You are watching: 5.3 vortec coolant temperature sensor location


*

I have actually a 2005 yukon xl 5.3L. The temp ~ above the dash reads normal but according to mine scan tool the TOT temp is analysis at -40f. From what I check out there are 2 sensors. I recognize where the one because that the temp gauge is on the driver;s side of the block close to the front. Walk anyone know where the second one is located? Thanks.

Usually one is by the upper radiator water tap outlet top top the engine, at the very least for many of the GM engines I"ve looked up information on. That is also feasible that there is one in a mirrored ar from the driver side one top top the pass side. On mine 5.7 over there is one near the header ~ above the driver side and also one the pass side in about the same location there is a clogged off port the would"ve been used for aux fan temp.

the ECT is at the driver side alongside the #1 spark plug on the head . -40 deg f means the circuit is open normal engine temp need to read around 170-230 ohms ... Don"t remove very first check the wiring connector and also the resistance the the sensor through the engine warm .. Typically the pins gain corroded ...

Pikey, shot your scan device on an additional truck, it just might be the end of calibration. One ohm meter top top the temp sensor is a certain thing.
