Ever since my car has bein heating up, my tranny feels sluggish. here are some of the issues I have. incorect timing, something is up with the MAF , put new radiator still over heats, tstat is new. could someone school me on my 88 tpi iroc?
Thanx in advance.

 

How does the air dam look underneath the car? Do the cooling fans come on?

 

Air dam is not complete, and fan runs constant.

 

Lack of an air dam will cause cooling issues at speed, car needs it to create the low pressure behind the radiator, and draw the air through. It's been a while, so I may be wrong, but if the car is moving at >35mph, the ecu won't kick on the cooling fans. If it's overheating when sitting still, and the cooling fans are running, you probably have much larger issues.

 

Going to check tstat, I put back the air dam and it's still getting hot.

 

Are you losing coolant ? If so determine where. May be a simple fix or a more serious problem with heads or head gaskets. As stated above the air dam is vital in keeping the engine cool. Is the radiator clean, good circulation etc ? Good luck !
