Engine Coolant Thermometer...?

Question

The Check Engine light went on for my 2001 Volvo S40 1.8T and I took it to Advanced Auto Parts for diagnostics. The diagnostics said that there was a failure in the engine coolant thermometer. They said they sell this part. Does anyone know if this would be a replacement that I could do on my own or if I should just bring it for service?

Answer 1

It's not a straight shot at the sensor and just pulling it out. You have to remove some coolant from the radiator, remove the reservoir cover, the splash guard under the engine (to get to the radiator drain), remove the thermostat housing, fuel rail cover, upper camshaft cover, remove a fuel injector connector to swing the therm cover out of the way and then remove the ECT connector and part. Plan on about 2 hours+ taking your time, not breaking any covers and putting everything back the way it was originally. I hope this helps.

Answer 2

The coolant temperature sensor is threaded into the water jacket at or near the thermostat housing, or in the radiator tank. AAP can show you where it is and then you can decide if you want to tackle the job or hire someone to do it.

Answer 3

its just a coolant temp sensor, it should be easy to replace but take your time, also make sure there is nothing wrong with the wiring. after you replace the part have someone clear the code for you

Answer 4

it is an easy fix you would have to remove the cap off the cooling system ( radator) Find your sensor un plug it and unsrew it put on some teflon tape and reinstall it the same way you took it off and fill the cooling system back up and bleed ther air out so it wont over heat

Answer 5

DO IT YOUR SELF IT IS PRETTY EASY JOB FOR MOST PEOPLE JUST LOCATE THE PART AND SWAP IT
