Hello and welcome. My name is ***** ***** I will be happy to assist you today.

They are sometimes bad about the radiators clogging up and causing an overheating. You can have that tested at a radiator shop or feel around the core when the engine is hot to see if there are any cool spots that would indicate a clog.
.
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:
Napa BK.(###) ###-####
OEM/Block Tester AUTOZONE
Part Number:

.
*****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.

I'm not understanding gas in crank case portion of answer
Expert:  Jerry replied 2 years ago.
Normally we get paid for the original answer(s) before any follow ups.
However, there is no mention about any gas in crankcase. There is however, a mention of exhaust gases in the cooling system as well as a mention of NOT filling the crankcase with coolant in most cases, as some people think.
