Phil,

For what it's worth, my wife's 89 BMW 325 temp gauge
was whacko/sporadic until we replaced the temp gauge
sending unit.  This cured the problem.  Symptoms we
had were much like you have described.

I have manual on/off switch on my vanagon.  It's great
to have when in a traffic jam on the highway when it's
95F outside... Just have to remember to turn it on.
It would be great to wire a  manual switch in parallel
with the automatic switch so if you forget, you don't
overheat.

Good luck,
Greg

Fan--Radiator/Coolant
Hell

Well after bleeding/wasting over two gallons of
coolant
and alot of jacking the Van up and down, my temp gauge
needle STILL is at "very hot"....then all of the
sudden its at "normal"-for like 15 minutes (while
driving)
So I turn off the engine and let sit for 15 minutes
start up again and the needle is at "Very Hot" again!
I check engine temp with my heat temp sensor gun and
it says 195F degrees.
No the theremostat is band new, same with the
waterpump that I changed out. If theres anymore air in
the hoses Ill sh*t a brick.

I am going nuts and after getting coolant splashed in
my eyes today(im lucky it was only warm) Im ready to:
A. Take it to a mechanic, he'll say"Duh..whats a
Tiico"
B. Drop the Radiator get it flow/pressure tested and
acid bath
C. start riding my mountain bike

What should I choose?

Phil
