They are sometimes bad about the radiators clogging up and causing an overheating. That may have been the original problem that caused an overheating

.

However, with any engine that runs hot, overheats or has been overheated it is best to check the integrity of the engine, (head gaskets and heads, etc.)

.

The first thing that you want to do is check the cooling system for any exhaust gases. Make sure that it’s full first. There is a tester for that, that you can get from Autozone for about $20. They will normally lend you the tester and you just buy the fluid for about $8. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases.

Block tester available is:

*****You will want to check it at different RPM’s and at different temperatures***

..

.

If there are any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high. Most times not filling the crankcase with coolant either and not smoke out the exhaust.

If there are, then there would be an internal engine problem, like a head gasket or head.
