Hi,

<posted to Facebook VOG as well>

I've got a 1991 Westfalia stock with a 2.1 L (stock) engine.

Heading home today, I got the blinking low coolant light.  Heart attack,
but the temperature was fine.

Pulled over immediately and sure enough the tanks were low.  Topped up
with water as I only had 50 km to go to my gf's place in Lake Louise and
I now knew my low coolant sensor is working, I wasn't too stressed.  The
temperature needle never wavered a bit.

Tried the parking lot repair and if it hadn't started raining, I
probably would have gotten it fixed.  It is what I believe is the return
line for the oil cooler.  Had to pull the oil filter off to get to the
hose & was overjoyed to find that the entire crankcase didn't empty out :)

Other than a brain fart, where I got impatient removing the hose,
thinking I had a spare piece that would fit... I cut the old hose off
the oil cooler.  Only when I got the hose cut, could I see that the 2
ends of the hose are different sizes :(

I had cut a slit lengthwise & if I was WAY more patient (or stranded up
a logging road, like I could have been if it happened yesterday!), I
could have fashioned a repair using the silicone repair tape that I
carry with me due to the great recommendation of this list.

Like I said, it started raining, so I went inside & had a shower and
pondered the situation.

I seem to remember reading on this list that the unit isn't so much an
"oil cooler", but an "oil pre-heater"... but I could be wrong which is
why I'm coming back to the list.

I'm 175 km from home on relatively flat roads.  It's not that hot out
here in the Canadian mountains.

On page 19.14 of the Bently, the hose that is blown is the one on the
oil cooler line on the "To Thermostat".

I'm thinking to block off the host at the thermostat end as well as the
hose coming from the water pump.

Am I totally out to lunch?

Thanks,
Steve Williams
