Pontiac Repair: Coolant Leak, intake manifold gasket, coolant temp


Question
Grand Am Pontiac 2003  Air Temp. Sensor appears to be leaking. 3.4 liter engine.

Answer
Hey Clyde:

I think what you see is coolant leak around the coolant temp sensor not the air temp sesnro. it at the rear of the engine with 2 wires on it near the radaitor hose?? If so it could be wither the bypass tube in the intake leaking coolant or more likely the lower intake manifold gasket id leaking and coolant it wicking up the rear bolts. good luck :}
