Where is it? Engine Coolant Temp Sensor 200

The ECT is almost the engine bay version of the heater blower motor.

When the one on my 1988 244 needed changing, I combined the job with a throttle body cleaning and oil separator box replacement.

Once the throttle body and oil separator box are removed, you can see the ECT.

It is not necessary to drain off any coolant for this job.

Remove the harness, same wire clip system as injector connection. Loosen the ECT just enough to get it free, then tighten finger-tight.

Not wanting to get any coolant into the crankcase through the holes that get revealed when the oil separator box is off, I laid over them a paper towel folded to be thick and narrow so it would sit there.

Next, with your hands, take out the old ECT and spin in the new one. A little coolant will drip out, not enough to worry about. Tighten and then go on with the job.

Good Luck,

Bob
