Coolant sensor


#1

The mechanic said that my 1992 Chevrolet Lumina

had a faulty coolant sensor and pigtail connector wire.



He charged $270 to fix it.



The car was cutting off at stop lights and the engine sounded like it wasn’t shifting right.



He fixed it and now it appears to run okay but I wanted to ask “after the fact” if that sounds reasonable.


#2

What did the sensor cost and how much was the mechanic charging per hour?

Secondly, was it the temp sensor or the low coolant sensor?


#3

Thanks, I don’t know the answer, other than that he called it a coolant sensor.

I just know overall it was $270, but I can look at the receipt later in the car.

Define reasonable.

The sensor runs between $20-$50 depending on what brand you buy and where you buy it.
The pigtail has come with all GM ECT (engine coolant tempterature) sensors that I have purchased. The pigtail can be purchased seperately for $12-$18.
It takes about 30 minutes to properly change the sensor, the connector, refill the cooling system, and verify the repair cures the customer complaint.
