Frequently asked questions

What is the sealing washer (10802070) used for?
The sealing washer (10802070) seals the coolant temperature transmitter adaptor where it threads into the engine. It sits at the base of the adaptor in the cooling passage and forms a fluid-tight seal to stop coolant leaking at the sensor mounting point on 2.25L and 2.5L diesel engines.
Where does this sealing washer fit on the engine?
The sealing washer (10802070) fits at the base of the coolant temperature transmitter adaptor, where the adaptor screws into the cylinder head cooling passage. It's the seal between the adaptor and the head on the 2.5L four-cylinder diesel engines.
Should this sealing washer be reused or replaced?
Replace the sealing washer (10802070) whenever the temperature transmitter or adaptor is disturbed. Sealing washers like this are typically single-use, the old one takes a set once torqued, so refitting it risks a coolant weep at the sensor on 2.25L and 2.5L diesel engines.
