I suspect that it makes sense for you to get 185* at water inlet on block vs 150* at bottom of radiator, given that you were getting around 185* at outlet from block. It seems reasonable that the block would be (+/-) at one temp with the radiator cooling the water from the block temp to about 150*. I have no expert knowledge of this - just a guy trying to think about your problem. HTH

My 31, after a 10 mile drive, outside temp 85-90 with the eng. at idle the temp. of the cly. head is 165-168, the temp. of the block is 155-165. I use 50/50 and if their was anti-freeze in 1928-1931 Ford would have used it.
If your car runs hot with 50/50 it will run hot on any other mix.
my opin. is you have a problem with your rad. or a block full of corr....That is, if your car runs ok otherwise.
I still think you have a rad. prob. JMHO

Did you say you have a thermostat in it? Is it a 180degree thermostat? ...fwiw,jm

Are you a club member or are there other A's nearby? Any chance of swapping radiators with some one elese whose DOESN"T run hot?? How's the new water pump coming along?
Please keep us updated.

Just changed out water pump today. I will make a run this afternoon and see what happens. I am fortunate that I have lots of club members to help.

I know this is an old thread.


Am struggling with same issue. Do not need advice on troubleshooting. Curious if radiator and if something wrong with it, or if undersized.


Is there is an update, what resolved your issue?


Thanks

There is a much more detailed post here in the barn. Radiator ended up being an aftermarket 2 core radiator. Stock radiator was three core. Bought a replacement from Bergs Radiator and all is good now.

Thanks much, I've eliminated everything else. I have a replacement 2 row 8 fin that was installed 4 years ago by a repair shop, not sure of brand, was assured this was what they have used on other As and never had issues. My A had other issues, had to flush/backflush for 2-3 years to get all the crud out, and the head gasket was bad so it has had the top end rebuilt with coolant passages manually cleaned. This was an inherited A that had a 50 year nap. Going to do a Block test, then I guess will have to upgrade my radiator.


Thanks for the quick reply.

My old radiator was fine as long as the temps didn't get above 75 degrees. It too was a 2 row 8 fin. Had it flushed twice. It just takes 3 cores to do the job.

Re: UPDATE....Ok so a brand new radiator and it still runs hot
 

I see you used a Bergs 3 row. I've had recommendations of the Bergs and the Brassworks 2 row 10 fin. Why did you choose Bergs? Anything negative about the Brassworks?


Thanks

Re: UPDATE....Ok so a brand new radiator and it still runs hot
 

I have installed 6 Bergs radiators without a single problem. Family run business that makes a big difference to me. I have installed only one Brassworks and I had a hard time getting the radiator shell to line up. Again if you will search the barn Berg's users speak loud and clear.

Re: UPDATE....Ok so a brand new radiator and it still runs hot
 

Thanks much for the replies, so much info on this site, hard to sift through it and make a decision. I saw a lot of info on Brassworks QC issues, but most posts were more than 6 years old, a lot of time for that company to improve. Am a newbie at age 65, and not that familiar with computers and searching a database - thanks for your patience.
