OVERHEATING PROBLEM
 

I have a 86 gt i can drive it for a good 30 mins before it starts heating up and its doesnt matter if im in traffic or on the highway. we have put a new water pump,radiator cap,thermostat and the fan and radiator is fine. we can a check for a head gasket leak and it checked out fine but im still thinking its a slow head gasket leak dont know what else it could be. any input would be much appreciated

Is it loosing coolant, does the oil look like a milkshake, and is the exhaust have a constant white smoke comming from it? otherwise no need to look into the head gasket as those are the signs its leaking.

no its not losing any coolant and the oils good. havent checked for white smoke but havent noticed any ill check on that though

i'm no mechanic but it kinda sounds like something is pluged up somewhere...maybe something in the radiator got clogged? tstat is sticking? have ya flushed everything out recently?

well it souds like u have eather a cylender head problem or a radiator problem. Try having your radiator checked by a radiator shop, and flush out the cooling system. And if that dosent work you might have a cylender head problem. You could have a head craked. I have had this problem befor. Let me know how it gose!!
