2006 Gr Px GT overheats in traffic.
1. Should the fans kick on when car is running or does the car have to reach a certain temp for fans to kick on?
2. Could this be a problem with the computer communicating with the fans?
3. Local dealer says it is a problem with intake valves; $550 solution. Does this make any sense?:th_scratchhead:
 


no it dont make sense at all.

are the fans coming on at all? around 212 they should come on.

they should also turn on when the a/c is on.
 


well theres your problem right there, not intake valves lol fvcking dealerships suck.

check the temp sensor under the t stat. maybe replace it if the wires look ok.
 
could also be a the fan relay or a fuse blown in one of the fuse boxes.

you can swap relays in the under hood fuse box. they are all the same pretty much.
