52 A overheating

check for compressoin in the radiator

Are you sure of the direction of the pump. We had one a guy installed with it pushing the water up through the radiator and it wouldn't cool till we reversed it to pull it from the bottom of the radiator. No problems after that.

I just double checked pump. It is going the correct way. And reason I put in a 1” valve is my thought was it was pumping to fast to give it time to cool down In radiator. I did have it straight no valve and noticed issue. Hence why I put in valve to slow pump down some. But same issue. This thing is not making sense. I get what you all are saying.

A restriction will actually build heat just like in a hydraulic system that’s how you heat things to test in the shop test get the hydraulic flow going then add the restriction in the line that’s flowing and cardboard in front of cooler. Same principal different fluid.

Valve will not be much help especially that small I think that whole output line being smaller is enough of a restriction.

Speed of flow through radiator shouldn’t hurt anything it’s going to cool about the same if you pull a thermostat out on anything with a water pump it doesn’t reach temp at least not fast. Thermostat (restriction) is there to keep it up the opposite of the problem you have. 200 again is also just fine this won’t hurt anything.

Your fan is probably not constant I’m more curious of that now as to when it turns on. Do you have it on a thermostatic switch? If constant than is it reversible? I had a motor grader of all things with a hydraulic reversing fan valve stuck and it overheated. Fan is more effective pulling air through pushing works but not as well it would reverse to blow the crap out the other way.

With fan on in the correct direction and full flow this should stay nice and cool.

Hey all. The fan runs all the time with pump. I just ran around reversed fan to push out through About 15 mins. It’s 230 tonight. Switched back to suction through fan and no change. FYI. I had a smaller radiator same issue. So I got the bigger one. Buddy of mine has the small one and claims no issue with heat. And thinks my A is odd ha

My 52 A is overheating after putting in aluminum radiator. I have a pump on it now too. Running through a valve to adjust flow rate. Nothing seems to help. Goes up to 200 quickly. Flushed system. New antifreeze etc.
any thoughts?

Get a temp gun and see what is happening how much is the radiator cooling. Next that fan needs a shroud it looks like there is a lot of radiator not doing anything.

230 is too hot that’s getting in the range of cracked head and more fun trouble.

I wouldn’t rule out the head as a culprit as well kind of the chicken or the egg it got hot and cracked the head or is the cracked head making it hot.

Get a big fan and point it at the areas your fan doesn’t cover on the radiator see if that helps cool it off fast. Maybe the buddies smaller one fits his fan better like rockcreek4630 suggested

I think ET got it right. That's quite a lot of restriction between the pump and the head. Why did you put a flow valve in the loop? What is the square loop behind the air intake?

The SS loop is just the breather line off valve cover. When I bought tractor previous owner had that on there

Factory radiator with water pump in bottom casting and original fan will fix it

Try a different temp gauge
