Overheating...UPDATE!
36 coupe, stock 21 stud, 2 Holley's w/3.5 PV's and 51 jets. Skips water pumps about 10 years ago. Bubba's dizzy 1 year ago. Would run 180 on hot days until 2 years ago. New radiator core and a good vinegar flush and rinse two months ago and I still can't keep it below 200-210 and it boiling over. What else do I need to do? Pull the heads? Small block? Any and all advice considered and appreciated.....Thanks....

Re: Overheating and fed up....
Hi Mike
1. Check the timing. Retarded timing will cause hot running 2. Rather than vinegar flush, try again using Evaporust. That will insure removal of all the old rust & give you a clean block |

Re: Overheating and fed up....
I've always, when the heads are off, taken a long screw driver and/or coat hanger and dug up casting sand out of the water jackets. Amazing how much can be left if the block has never been boiled. Just probe around with the coathanger and flush it out.
You might have an exhaust leak also heating up the coolant. There are a few ways to check and maybe someone else can explain it better then I will. One way to check is to remove the top radiator hoses with water in the block and look for bubbles. |

Re: Overheating and fed up....
Timing is always worth checking . . . but it seems you had the problem before you replaced the distributor (or rebuilt it).
Have you checked the plugs . . . are they consistent and do you see any sign of 'washing' away the carbon on any of them? If you have a blown head gasket, in many cases some steam or water vapor will get into the cylinder and 'wash' the spark plug. Have you had the water tested to see if you have compression gasses leaking into the coolant (blown head gasket)? If you warm the engine up and then pull the radiator cap and rev the engine - do you see bubbles or signs of compression leaks? Are you running thermostats - have you ran it without them? How fast does it heat up and under what driving conditions? Give us a bit more to work with. |

Re: Overheating and fed up....
I did use Evapo rust after the vinegar flush. Left it in for a few days, as I did the vinegar, and thoroughly flushed with water. I'm sure the block is clean. No thermostat's per Skips instructions. New spark plugs and no sign of water in the oil or bubbles in the top tank. It heats up normally I would say. I'll email Skip tomorrow for his recommendations. Thanks for helping, I really want to keep the flathead ......

Re: Overheating and fed up....
I'm willing to check/change the timing, should I use a vacuum gauge? I would think Bubba set it up correctly......

Re: Overheating and fed up....
Ted ,the 33 has no shroud and will stay cool towing in 42deg C, BUT with the fan off the generator, it ran 10 C hotter at hiway speeds,put it back on and it dropped the 10 C.
Clean radiator,clean block,good pumps ,timing close enough,no head gasket leaks,no cracked heads, thats what I have found.and we do a lot of miles towing in Hot weather for long distances. Lawrie |

Re: Overheating and fed up....
Could it be a leaky head gasket letting hot exhaust gas into the water jacket ??

Re: Overheating and fed up....
Do both sides get hot the same----remember the engine block is 2 seperate systems, i had a truck with duals and under load one side would overheat, I found that the muffler on that side was too restrictive
I don't like any waterjacket treatment that removes ALL ther rust, sometimes the rust seals a small crack or porosity, Have you drained it down and looked into the top tank of the radiator to see if some tubes are clogged are you using plain water---or antifreeze ---plain water makes more rust I have a "ZOO flush gun", it hooks to the hose and air, connect to lower hose, when block full of water hit it with air ---the air pushes the water out very fast bringing the crap with it----then do the same with the radiatyor, (but at lower air pressure and not as much all at once to prevent rad damage)---this has worked for me how are the plugs burning---white or black, when you drive does it run proper, and have the same top speed can you push the car easily by hand----could the brakes be dragging |

Re: Overheating and fed up....
Both sides get the same temp....hot....It's a new radiator core with bigger tubes than stock. Water and antifreeze and No Rosin. Plugs are a tan color. It sucks trying to diagnose...

Re: Overheating and fed up....
If it is cracked you would be getting water loss .so it doesn't sound like that ,How's your tempter gage ,stock or other wise .are you loosing water out the over flow ,Some radiators will not cool a flat head ,on one of mine even though the radiator is clean the only way I can get it to cool is with a shroud ,Wouldn't be with out it ,Ted

Re: Overheating and fed up....
The strange thing Ted is it kept at 180* in 90* heat until 2 years ago. Then started overheating. The water does come out the overflow and this is a brand new core better than the one Ford put there....I need to find the cause and fix that instead of adding additional measures that will bring the temp down.....I don't see any symptoms of any cracks...

Re: Overheating and fed up....
I have a similar problem , I did not re-torque the head gaskets. and one side is overheating, leaking combustion into the water jackets. It overheats at an idle within ten minutes. So I need to replace a head gasket.

Re: Overheating and fed up....
I emailed Skip and he responded quickly with some tests I should perform to verify water flow through my engine and we'll go from there. I'll do this within the next 2 weeks and post the results. Thanks guys.....

Re: Overheating and fed up....
Maybe we have been over this before but here goes. Rust in the block will not make it overheat. Cooling takes place in the radiator not in the block. But rust from the block can block radiator tubes and that can be a big problem. If there is rust blocking the radiator tubes Rust911 is a great product to remove it. You can get it on Amazon for about $50 or $60 dollars a gallon. That gallon makes 16 gallons of rust remover. I used it on a 1913 Oakland radiator and was amazed at how well it removed the rust blocking the top of the tubes. I also always use distilled or deionized water in my radiators. Ordinary tap water can have minerals in it that cause teakettle scale to form in the radiator that insulates the tubes on the inside. Vinegar should remove most of that however. Jim in San Jose.

Re: Overheating and fed up....
I had the same problem with a Model A engine that had been rebuilt by a "specialist", I gave up and purchased a "Diamond Block" and did a rebuild with an experienced machinest. My car runs at 160 now on a 90 to 100 degree day using water and water wetter.
Did an autopsy on the old engine, all the water passages were blocked. Over years of use and rust, this was the problem, the engine had also been over bored. |

Re: Overheating and fed up....
Were you running without thermostats 2 years ago when it was cool? Just curious. I know some flatheads run best that way but over the years, on other engines, I have seen the water circulate too fast to cool without them. Just my opinion, but if everything is right, you shouldn't have to run without them. To me it's akin to putting cardboard in front for winter, a bandaid.
Anyway, you have a lot of good suggestions here. I'd check the timing and look for bubbles first, cause that's easy. |

Re: Overheating and fed up....
Think I read all, seems to have started heating up immediately after new radiator was installed? The fact that both engine banks overheat at about the same rate kind of indicates problem is in new radiator, might have silver solder or braze media clogging or some other radiator fab issue. If it were in the engine I would expect one side to be hotter faster. Mine always runs hotter on the passenger side of the engine, 185 to 195 vs. 165 to 180 on driver side.

Re: Overheating and fed up....
Ran 180 without thermostats and Skips pumps until about 2 years ago. Put new radiator core in 2 months ago. Still overheats. Radiator is not clogged, flushed engine and now runs clean but hot...200-210...and boils over. I'm going to eliminate some causes with some testing and I'll be glad to report back before I install a 283....

Re: Overheating and fed up....
That is the problem I found with my 40. Combustion was leaking into the coolant.
It is amazing how fast that side of the engine heated up |

Re: Overheating and fed up....
There is no evidence of water in the oil so I'm assuming no crack? Is that possible?

Re: Overheating and fed up....
Think the suggestion was combustion leaking into water spaces possibly via a crack which will not show up as water in the oil maybe. Cooling water can be checked for hydrocarbons associated with combustion leak to water space.
Maybe a compression check also to assist. That is a very nice looking car and deserves TLC and plenty of use. Phil NZ |

depends on the crack but no milky oil is always great. I thinking sbc! Time will tell, don't throw the baby out with the bath water.

Re: Overheating and fed up....
With the exception of my last 2 years with an 8BA, the majority of my 40 years experience in dealing with engines has been with conventional overhead valve stuff. You can have combustion gasses having a significant effect on the water jacket temperature from a head gasket malfunction and not be able to tell other than with a block tester.
Barring something obvious, like a jacked-up radiator, that's where I'd be looking. |

Re: Overheating and fed up....
I think you're right on the combustion gasses. What leads me to this is it came on all of a sudden and my system with the new radiator and flushing I did is very clean. I'll do the test just to make sure....

I agree with willowbilly. 180 thermostats should slow the coolant flow somewhat and allow the coolant to absorb more heat from the engine parts. The engine should run more consistent with less temp gauge fluctuations. I would also pressure check the radiator cap to make sure it holds it's rated pressure. If it fails, coolant over-heat may occur. Antifreeze strength should be checked for 50/50 mix or -35F. If the strength is too high, heat transfer will be impeded raising engine temp. Water shouldn't be used alone as it has no water pump conditioners and antifreeze acts as a form of water-wetter to draw heat to the coolant. |

Re: Overheating and fed up....
We don't need thermostats here in SoCal. It ran great without them and I don't think adding them will make a difference. It's more likely, as suggested by other HAMB'rs, combustion gasses as it overheated all of a sudden, it never did that before so that leads me to believe a head gasket blew or something similar. That makes sense to me. The first test I will do is to see if water flows through each side unimpeded and go from there. My guess is I will pull the heads off to fix it.......I appreciate all who made suggestions and will report my findings. Viva La HAMB!

Matter of prospective, some of us believe all engines need thermostats. (and others don't, LOL) Many advantages to running an engine at a higher temperature.

Re: Overheating and fed up....
Mike;
Drain some water from the radiator if you run anti-freeze, if just water don't worry about it. Remove fan belt from water pumps & remove the radiator hoses from the heads. Start engine & look for bubbles in the water. |

Re: Overheating and fed up....
I didn't read all this thread but, are your thermostats opening completely?
Are the radiator hoses collapsing? |

Re: Overheating and fed up....
Mike -- had the same problem, went to a couple of shops and they used the exhaust gas sniffer right at the radiator neck. The readings were over 30PPM. Removed the heads,
surfaced, Best head gaskets, redid the readings twice and it was 0-4 PPM. There must be a shop in the land of gracious living or over in the Brea area.

Re: Overheating and fed up....
You can get a NAPA kit (BK 7001006) to test for combustion gases in the coolant. It's a quick easy test and cost is under $50.

Re: Overheating and fed up....
OK, did some testing.....first checked that water flowed freely through block and that passed, flowed right through. Then did what B-O-B suggested with upper hoses and fan belt off. Saw a burping in the water on the pass side nothing on the driver but driver got 10* hotter and water would overflow the pump flange while pass. side did not. Didn't see any large bubbles on driver side. Any more test suggestions before pulling the heads? Thanks....

Re: Overheating and fed up....
I would suggest re-torqueing the head and if you decide to take a stab at it be sure to back to nut off and record how much torque it took then re-torqueing the nut

Re: Overheating and fed up....
Mike, I have a v-8-60 that I run in a vintage kurtis midget race car. Had over heating problems until I added "Water Wetter" a Red Line product to the red. went from 210 down to 180/ 190 you can get it at any parts store

Re: Overheating and fed up....
OK.....after much thought, I decided to pull the heads to check gaskets and look for cracks. First, the water pumps are all corroded with something. This mix has been in for two months. It is a mix of A.F/Water/and No-Rosen suggested by Rumble-seat's blog. After cleaning.. It looks like the impeller is being eaten away.... And the last photo is the root of my overheating. Sandy sludge between the back cylinders. How should I get this out without screwing something else up? Appreciate all suggestions.....Having problems getting all photos here...

Re: Overheating and fed up....
Sandy sludge. Is it core sand? Was the core sand cleaned out of the block at the last rebuild?

Re: Overheating and fed up....
I suspect that new radiator. You say larger tubes, not necessarily good. How many rows? You need 4. Aluminum or brass? Brass cools better. And clean out that block! Hot just in town or on the road too?

Re: Overheating and fed up....
Maybe it just needs burping. Jack up the front, remove the cap and run it awhile. The trapped air will bubble out if there is any.
Also, run thermostats. |

Re: Overheating and fed up....
mike that's not so good to hear about your issues. ive never seen that crud on a water pump like that before. I wouldn't think the casting sand is your issue, I would say it was the crud on the water pumps which ha caused them to move/pump only a small amount of water. sand has been there now for 81 years and never caused any issues previously, now you know about it, its best to get it out though. I would think you will need to get the block out and spend a bit of time with a screwdriver loosening it as you wash it out.

Re: Overheating and fed up....
The sand had to come from somewhere! It is either getting added to the cooling system somehow or something is causing the original casting to come loose and move about. Almost everyone that takes to time to clean the blocks out (they have a ton of sand and wire in there!) claim much fewer cooling issues. The only other thing I can think of is something is going on with the coolant that just appears to be "sandy". But if it is truly fine sand, casting sand could sure be the source.

Re: Overheating and fed up....
Phil, It overheated with the old radiator also. It's brass similar to the old style. I plan on cleaning out the block. I did flush out the block before the new radiator went in as well as you can. It gets hot where ever I drive it....

Re: Overheating and fed up....
Several years ago when I had to replaced the heads on my '34 I decided to clean out the block as best as I could without removing the engine from the car. With the heads off I scraped the water passages as best as I could with various lengths and thickness of stiff wire like coat hangers. I used various flat tipped screwdrivers as well. I then used extreme high pressure compressed air to blow out every orifice in the block that I could see. I was amazed at the amount of sand and debris that was blown out of that block! After the job was done and having the car out on the road for several months I found that I had to add thermostats for the first time ever because the running temperatures would never get over 140 degrees. I installed a pair of 160 stats and the car has never run better....

Re: Overheating and fed up....
Wow! What crap. You will have to keep your eye on that in the future.. That may not be the last you will see of that. May have to be run and cleaned out several more times.

Re: Overheating and fed up....
You can also blow out some of it with an extended air nozzle. BUT be aware it will blow a cloud of junk everywhere!!!

Re: Overheating and fed up....
Mike, I use both the shop vac method with a rubber hose, and then used a pressure washer with out the sprayer tip on it. Just used the sprayer tube and was able to get a ton of crudola out of it. Also with the heads on, and no thermostat, used a high pressure down the housing and into the block in an effort to wash it out as well.
If you need radiator work, Rick's out in Azusa does excellent work, and knows old Fords. 693 E Arrow Hwy Azusa, CA 91702 Do you go to the cruise in at Dukes on Wednesday's

Re: Overheating and fed up....
I just had the heads off a 59AB engine. Lots of rust in the passages, I used a long 1/4" aluminum pipe on the end of an air nozzle to blow out all the crud. It took some time to get it all. The engine runs a lot cooler now.

Re: Overheating and fed up....
Mike, it seems you have done all the things to make it run cool. I don't know how to sure; but can't you do a "LEAK DOWN TEST". I believe by brazing/welding a shadrer valve onto a spark plug, so you can blow air into a cylinder. Fill one cylinder at a time to about 90#. Then watch it if holds pressure for a length of time. This hopefully would show which cylinder has a bad head gasket, crack, ??? Maybe other Fordbarners can share info how to do a leakdown test. Any how, I share your frustration. Hard to truly enjoy your car/hobby with it not running correct. Good luck.

Let him clean the block out first! A block full of sand is not going to cool well.

Re: Overheating and fed up....
Thanks guys for all the suggestions and advice. I appreciate all comments. I 'll post photos of what comes out. I'm hoping this is the problem. I'm letting it dry out and will probably get to it in a week or so......wish me luck!

Re: Overheating and fed up....
Wow! That's a lot of crap; getting it out of there should help a lot. About the crack, I'm not so sanguine. I used to run 'em like that in the '60's with no problems, but these days? Good luck to you!
I ran a '52 Ford for several years that had cracks like that in 7 of the 16 valve pockets without a problem. I think I was really lucky. |

Re: Overheating and fed up....
Yeah, I was going to say the same thing....I had at least twice that amount come out of one side of the engine in my '34....

Re: Overheating and fed up....
This is only a small amount I scraped out of my block, I did it twice. Using compressed air to move the smaller stuff everything around the work area turned brown...

Re: Overheating and fed up....
OK, wanted to follow up with the results of my work. New head gaskets, added water, antifreeze, water wetter and Barrs copper block seal for that small crack. Also, re-torque after warm up twice. Temps get to 185-190. After running it on the freeway and I shut it off, it crept up to 200+ while not running, that seems strange....Now I'm going to install thermostats and see if they help/slow the fluid down even though I never ran them before. I appreciate ALL suggestions given. Thanks to all that took the time to read and respond. I will post the results soon but now I'm into my 46 woodie that overheats....That's a post for another time. It's always something......

Re: Overheating and fed up....
Mike ,there was a recent thread about deposits in an engine that looked just like your water pump. The conclusion was that the combination of Water Wetter and NO Rosion caused the deposits. Apparently you can not mix some of these chemicals.
Glad you solved your problem. John |

Re: Overheating and fed up....
I just had a flathead engine baked, shot peened and shaked. I dug around in the block and blew air through it and did not get any left over debris out of it. I'll flush with water to triple check before it goes on a radiator.

Shake& Bake. Walt in Me did an engine for me and he had it cleaned up there somewhere. It looked great before he got into the rebuild. I was really pleased With what I saw. I would take any other engine to that place. and I should have gotten the name and phone. kerk

Re: Overheating and fed up....
I have my 36 radiator at toms right now. I hope he does a good job. I almost went to hoffmans down a couple of blocks. I still waiting to hear back, he's had it about a month.
