ECT sensor on 2002 Volkswagen EuroVan

can someone direct me to some instructions on how to change the ect myself?

It looks like it's in the coolant manifold where the hoses connect on the cylinder head in the front area of the engine compartment. With the engine cold, it should be fairly easy to remove it and install the new one without having to drain the coolant. Just remove and replace the coolant cap to equalize pressure before you loosen the ECT. Wear your goggles.
