Water Temp Gage

[davidbrady]

My LXi had two coolant temp sensors mounted on the head behind the turbo.

The shiny one is the DDEC ECM sensor; the one to the right is the dash gauge sensor. The DDEC ECM sensor is shiny because I replaced it.

On the way home from Kamloops CN, my H3's dash coolant gauge started to go whacky. I stopped in at Prevost in Goodlettsville, TN to have them replace the sensor. My H3's S60 has only one coolant temp sensor. The dash gauge uses the same sensor as the DDEC ECM. They do go bad. It's worked flawlessly since.
