Wondering if anyone can help here...engine was =
overheating due
to obvious lack of antifreeze,
but there are no obvious signs of leakage anywhere. =
Pressure
tested the system
at like 20lbs for 30 minutes, and not a drip =
anywhere. If my
main fill tank was down where did
it go?
Here's the
situation:
'89 westy overheated and light came on the temp =
guage a few
months back.
Took it into the shop and they checked everything, =
flushed it,
pressure tested the lines, fan works, etc and no obvious
cause. After they do all this though, the =
guage stays normal and seems fine so drove it away. =
A couple of months later it happens =
again.
Only this time, its clear why: the main antifreeze =
tank is
low, so we've lost coolant and that's the cause. Everything else in the =
system
including radiator fan checks out. Great. So refill and
everything seems cool, for now. But the shop can find no obvious signs =
of
leakage anywhere, not even a stain, and there's =
nothing
obvious that says where the lost antifreeze was going.
Anybody have any clues as to the nature of the =
problem, given
a)thermostat works, b)fan works and comes on at the right time, and c)no =
obvious
signs of leakage.
