It's also possible that there are
coolant draining plugs on the engine block as well.
Not exact matches
I am soon doing a
coolant change on my car, including
draining the
coolant from the block using the
drain plug, and I have heard of a few people apparently snapping these off due to over torquing them,...
After removing the blue
drain plug (my car only had one, apparently some cars have two) on the bottom of the radiator and another
drain plug on the side of the engine under the exhaust manifold, my expansion tank still has a bunch of
coolant left in it.
Yet to
drain the
coolant usually the procedure is to use the
drain plug at the radiator.
There is a modification that is on the TDIClub.com that puts a hole in the middle of the connector
plug to let the
coolant drain instead of flowing back into the wiring harness.
