over heating problem

When I'm in stop and go traffic my temp spikes. Clean air on the interstate is all good. Is this the thermostat or one of the relays? I've heard both. Thanks

Check the area in between the radiator and the AC condenser. They are notorious for clogging with road debris. You'll need a long handled soft bristle brush to clean it and or a power washer.

What do you mean by "overheating?" Normal ops is about 192 on the road and 220-225 in the drive-thru at burgerland.

Yeah define "overheating". 220-230 is not overheating.

it gets over 225 in summer with a/c on in traffic. Relays looked good, thought about putting a new thermostat in

Low pressure from the engine side toward the front of the car to dislodge any debris that has been thrown up against the radiator fins. C5's are bottom breathers and suck up anything on the road and that is the most likely cause of heaing in traffic.

However I would also start with insuring the surge tank has coolant up to the "COLD" mark on the end of the tank.
