  • 1997 CHEVROLET MONTE CARLO
A leaky water pump was replaced a couple of days ago, and I noticed the temperature was erratic. It read 260 degrees and I stopped to check and the car just didnt seem to be running hot. Yesterday I went to take the car back to have it corrected, and when I got into the car I noticed the temperature gauge was sitting at 260 degrees, even though the car had been parked in the garage all night. The dealership wasted two hours of my time and gave me a song and dance about needing more time to diagnose the problem and letting them have the car for a day. This doesnt seem like rocket science and I refuse to believe it takes two hours, not to mention a whole day to diagnose what should be a simple problem for them. Can you give me your idea of what the problem could be so I can help out these overpaid mechanics? This cost me 388 dollars.

"Run the engine, find the coolant temperature sensor disconnect it if the 260 still showing."

1. Whats does it indicate if after disconnecting the temperature sensor it remains at 260 degrees?

2. I assume if the temperature gauge indicated a cold reading after disconnection, it would show the sensor is working properly?

3. What problem is indicated if after sitting in the garage all night, the temperature gauge is pegged at 260 degrees, and the car is dead cold?

The gauge is erratic. It is not always at 260 degrees. It flucuates from normal to hot infrequently. This problem was caused by the tech who replaced my water pump and I cannot understand their having any difficulty correcting it. Thanks

Assumptions, maybe he didn''t connect the proper harness to it or the wire to it is shorted or the gauge itself
