Temp. Coolant
Difference between temp. coolant sensor and temp. coolant switch and where located on both would be very helpful to me. And what's the sensor on the bottom of the plenum on a tpi setup? Thanks

Re: Temp. Coolant
The coolant temp sensor sends coolant temp to the ecm. This is located on the on the front of the intake above the water pump. The coolant temp switch turns on the cooling fan when the coolant reaches a certain temp. This switch is located on the pass. side head in between the #6 and #8 spark plugs. Can be a pain to get to. The sensor screwed into the bottom of the plenum is the IAT sensor(intake air temp sensor). It sends air temp readings to the ecm.

Re: Temp. Coolant
@jermdm, this is probably a stupid question, but are the coolant temp sensor and intake temp sensor the same sensors? I ask because the local parts house said so and sold me two of them, but my car really never has run right and I'm wondering if this could be an issue???
thanks for any help on the matter.
