radiator weeping
I'm seeing some crystal growth along the top seam of my 40 Merc Dearborn car.
I really don't want to R/R the radiator. What sealant should I use that won't plug up the radiator any. I have a heat problem as is. Clem |

Re: radiator weeping
If you "have a heat problem as is", wouldn't this be a good tome to pull the radiator and have it repaired properly? I don't know if this would effect your "Dearborn Status", but I would rather risk that than a cracked block or other side-effects of overheating.

Re: radiator weeping
If your radiator is not pressurized apply a smooth bead of black rtv to the seam. Wonder if that FLEX SEAL stuff "as seen on TV" would work as a short term solution.
The truth is, you should R and R the radiator to prevent a costly disaster as the leak will only get worse. |

Remember those ads where Chuck Yeager said "Never wait for trouble"? (even though it was a GM ad) |

Re: radiator weeping
old timers back in the 1930's used to pour a small size box of pepper into the radiator. This would have the small soft ground pepper fill and tiny cracks.

Re: radiator weeping
Just had to have the radiator in my 1950 F1 recored. I checked into new replacement radiators. Aluminium had overflow on wrong side, no provisions for shroud, set up for high pressure, Drain in back instead of front. New Brass works radiator was $800 and had some of the same issues. I bit the bullet and got my old radiator back with the new core and no issues. Sit down and weigh the pros and cons.

Re: radiator weeping
When I worked for a Ford dealer, the "factory authorized rebuilt engines" always came with a contained of material, usually "Barr's Leaks". Ford flathead blocks often were fragile due to "core shift" when they were cast. Machining during rebuild would cause internal leakage. Many years ago when I visited the Ford Rouge plant I was surprised to se a virtual mountain of engine blocks piled up out in the yard. The failure rate of newly cast blocks was very high. When we removed the water pumps during repair, we often dug out heaps of core sand with a length of wire. This stuff could, and did, impair cooling.

If you are interested in a Rumble Seat recommendation: "Recently I came across BG Cooling System Sealer (part #571). ABSOLUTELY SUPER STUFF! I saw a demonstration where the bottom of a beer can (I volunteered to empty it first) had been punched with an ice pick several times. They filled the can with water and held it up so the water poured out the holes. Then they added a mix of water and their tan colored sealer. The water completely stopped streaming out of the holes in less than 5 seconds!!!! Great stuff. Since it’s organic, it doesn’t harden in the system...It simply stays in suspension until there is a leak. Another thing I like..... flushing the system flushes it out. It doesn’t adhere to the walls of the cooling system. I use it to seal head studs and head bolts when building an engine in addition to sealing radiator leaks on the road. It’s so good I carry a can of it in my heap all the time. You never know when a rock or something will cause a leak. Oh yeah.... it will seal blown head gaskets if the hole is fairly small..."

Metamucil psyllium powder works for me. Unsweetened of course. 8^) Jack E/NJ
