If the air dam is missing, the car is guaranteed to run hot.

You check the water pump by viewing fluid movement in the radiator.

Someone asked what the actual temp was that it got to when the fans came on. So what is it REALLY not what the gage says? What temp is the PCM seeing? Maybe it's thinking it's colder than it actually is and doesn't start the fans at the correct temp?

Since you hit a bump and the oil pressure gage went south, I would think you have a wiring issue that seems to be effecting at least the temp gage. No?

check your coolant temperature sensor...

make sure all your hoses are routed correctly...

with the car running look in the radiator and make sure there is coolant circulating, you should have a steady stream coming from the steampipe into the radiator..

find a mechanic that can block check your cooling system. it is a chemical test to determine if combustion gasses are present in the cooling system. or find a tool truck or supply house that can sell you the kit and perform the test for yourself. you may have a leaky head gasket, or cracked cylinder head castings.
