I did flush my radiator a few weeks back, but I don't recall dealing with any coolant sensors..

The reason I'm asking is because I am using the "search" function for "Service Engine Soon" light..


Thanks! :icon_idea:

Yes.

It's in the coolant crossover in the intake manifold, and I believe that it is on the passenger side. I distinctly remember it's passenger side because I had to extend it for the Cobra crossover's sensor on the driver side.

That is the coolant temperature sensor.

The coolant level sensor is on the bottom of the coolant reservoir tank, driver side, right by where the hose goes down to the thermostat.

Look just above the lower rad hose.

I don't know about the others but mine is in the coolant tank. When my coolant got low then it got stuck. This is not a recommeded repair but I took a rod and went through the filler tank to loosen up the float. It worked. The SEL never came back.
