1.) Begin by having the car OFF and somewhat cool; you will be dealing
with hot coolant if the car has been driven some time before.
2.) Locate the coolant drain plug on the coolant pipe of the VR6. It's left and quite
above the oil filter housing; it's a quarter sized plug with a flathead screwdriver fitting in it.
3.) Unscrew and let the coolant drain out into a collection vat; expect to get about a
little less of two gallons out of the system.
4.) Once drained, re-install plug. * Note: Do NOT overtighten
the coolant drain plug since the coolant pipe and plug are plastic. If overbearing stress is applied, the coolant pipe
or plug could crack and leak. *
5.) To get the residual coolant out of the radiator, remove the lower radiator hose from
the radiator. Reconnect once all the coolant is drained out.
6.) Premix new coolant (VW G11 or G12 -
phosporous free [depending on year application] ) with distilled water in a 50% - 50% or 60% - 40% (for colder climates) ratio.
7.) Remve the expansion tank pressure cap and add mixed coolant to expansion tank; fill
to MAX line.
8.) Start car and turn on the heater. Fill the expansion tank if the coolant falls
below the MIN line. Re-install expansion tank pressure cap.
9.) Drive normally for a few days and periodically check level of coolant in expansion
tank. Add premixed coolant accordingly.
