How To Remove Thick Paint From Radiator??


I want to remove many layers of paint from a radiator.
The radiator is fine not thing wrong with it, just to much paint on it, when its very hot the temp of oil in radiator increases even with fan running.
Question is what removes several layers of paint on a radiator?

Like a car radiator? Or an old boiler radiator found in old homes?

Try the orange paint remover at depot. Stuff works great and is safe.

I think they are typically shot blasted. This old house had a segment on them.

As mentioned above this stuff works great. I've used it a bunch. On the flip this paint has been baked over and over. What type of radiator? Theres probably a bunch of led (spelling) there so I would ventilate well and if possible use a respirator how ever you tackle it.

The radiator is on my small wheel loader. Its a Deutz oil cooled engine.
After a couple paint jobs it has a problem of cooling the oil when the air temp is hot in the 90's.

Not an easy one to replace either I guess?

I would try heat, a heat gun wouldn't get it hot enough to melt the solder.

Call around to a radiator shop and see how they do it. I'd guess blasting or chemical bath.

Take it to a radiator shop.
They will cook it inside and out. If the tubes have crud in them it will help restore the cooling.

Purple Power will melt the paint off of the aluminum fins. You can get it at most auto parts stores. Lightly cut it with water, spray it with a spray bottle. Then use a garden hose to wash the paint away. Trojan Loader?

I agree with Timnj. If it is a hard to find radiator it would be well worth having flushed, dipped, pressure tested and flow tested. When finished they will paint it black like original. Money well spent IMO.

Laquer thinner. Don't smoke and make sure nothing is hot around it.
