My '84 Westy is running slightly warmer than usual. Recently, I
popped some hoses off for inspection and to begin tracking down the
source of coolant loss, and used that as an opportunity to flush -
using the garden hose method, at several different hose connections -
the old coolant. I then sealed up the whole system, filled with
water, and repeated the process several times . It gave me good
practice at raising the front, and bleeding the whole bleeding
system. Not an unpleasant job, though a bit noisy: no exhaust system.

Now, with a shiny new Bus Depot exhaust system kit  (delivered in
three days:), I could hear the source of my coolant leak: the water
pump. I took the van to a VW specialist (30 minutes, 40-60 mph). On
the way to the mechanic, my temp needle was on the left edge of the
LED warning light. Left edge, nice and cool. Driving home, with a new
thermostat (87C) and water pump, the needle was right of the LED.

I've topped off and bled the system since, and believe the air is out
and the system is full.

So, the recent changes are: all new exhaust and O2 sensor, water
pump, and thermostat, plus some back flushing with the hose. Why so hot?

Also, fwiw, I did my fuel hoses 5 years ago, thanks to the
(legitimate) paranoia of this list.

Thanks all,

Kevin
