so my car keeps overheating, i replaced the thermostat, all hoses antifreeze system has been purged but still overheats i can't figure it out, would a blown coolent seal do that? I was thinking the radiator next an aluminum one i don't know what do you guys think

have you replaced your rad cap..that could be shot?,allowing the cap to Open early and make it look like the engine is Overheating when it isn't..What does Your Temp gauge Say that the engine is "doing"??..But the best thing would be a cooling pressure test..also a engine compression test..if the car Frequently overheats there is something wrong.and yes a blown coolant seal could do that,by letting Engine Compression into the Cooling system..Oh another thing,is I am wondering If the Thermostat was Installed the "right Way".it could be simple as that too.

 

ya the cap is new, the gauge will read hot then go down then it will jump up again, the go down, but if its cold outside it will stay cool longer ya , i'm going to do a compression test today so i'll let you know

 

water pump? it should stay hot all the time but if it is no moving water that is where you get the jumpin from

 

i'll have to order a new one thanks bro
