so i pressure tested my coolant sytem and it held 18 psi. my engine is still overheating and i tested for a headgasket and i know i dont have it blown. i do see some leakage/old oil buildup on the passender upper side intake gasket area where the alternator should be could this be messing up my coolant system? idk 100% that it is leaking but i do see some kinda old oil/sludge around that area.

 

Have you checked the thermostat, purged all the air out of the system, are the fans coming on when engine gets hot enough?

 

Are you sure it is really over heating? I used to think mine was but the factory temp guage was way off

 

i am unsure if the fans are coming on when the engine gets hot, i have purged all the air out i am sure of that. brand new thermostat.

 

well when it overheated it blew out the overflow tank, pressure tested and found out i had a leak in my radiator. so i replaced, now i have a brand new one and its still overheating and it holds pressure now.
