There was coolant under the left rear of the engine =
so I took
a look. White powdery substance on a coolant pipe. The =
coolant
looked to me to be coming from the top of the expansion tank, around the =
sensor. Took it in to a shop. The mechanic says there is a =
leak on
the side, where the two pieces of the tank come together, so we ordered =
a new
one. Straight-forward. The part should be in today. =
We'll get
it in tomorrow. But in the meantime the coolant warning light on =
the dash
has started blinking all the time--even when the engine is stone cold =
.
Although the temp gauge reads normal. I thought, ok, we're low on
coolant. Added some to the overflow with no result. Pulled =
the cap
off the expansion tank, thinking it would be low--but it's full to the
brim. This I don't understand. Could it be simply a bad
sensor? Does it sound like the coolant flow is restricted =
somewhere
too? Or do I have excess pressure in the system? I searched =
the
archives for the past 21 months but didn't find an answer.
We don't see many vanagons around here, so it's =
probably
impossible to find a mechanic that has a lot of experience with =
them.
Therefore, I'm turning to the list before this mechanic gets too deep =
into
it.
BTW, we took the westie 2300 miles in June from =
Missouri to
South Carolina and back and the gauge stayed steady at just above the =
warning
light. We then took it 6700 miles up to Canada, across western =
Canada,
then down the coast to San Diego and back to Missouri. The gauge =
ran up to
2/3 on a hot day on the interstate heading north. Was fine in the
Rockies. But we lost a little coolant. Discovered a leak in =
a
coolant pipe which was replaced in San Diego. On some steep grades =
heading
to Jerome and Prescott, Arizona the needle went all the way to the top =
and the
fan came on momentarily, but other than that it behaved ok, so I don't =
know if
we have a cooling problem. I have given some thought to a new =
radiator,
though.
Any advice on the expansion tank leak and on keeping =
cool in
general would be appreciated.
Thanks,
Bill
