I've got a 95 golf VR6 that is losing antifreeze. There doesn't appear to be
any puddles under it but over a week I lose about a liter. I have read that
there is often a leak where the plastic block with the temperature senders
are attached to the block. Is it possible to lose that much out of the
temperature sending block on the engine without leaving a puddle?
Also, the water system always seems to have pressure even when the engine is
cold. Is that normal?
Any ideas would be appreciated
Thanks

Don't know much about the VR6, but I'll give it a go anyway. So here.
..<==grain of salt
Sounds similar to the plastic 'gooseneck' on the 2.0l, 4-cyl engine.
That one's prone to cracking and losing coolant. You should see a track
from where the leaking coolant dries. It may only leak under pressure
since it sounds like it's up high in the system. Hot coolant would tend
to evaporate, and when it's cold it won't leak much, so no puddle.
Don't know why it would always have pressure. Maybe the cap's not
popping releasing pressure as the system heats, etc?
So your homework is, look for coolant tracks or traces, and either get
the cap tested (if it's expensive) or replace it (if it's not).
Good luck,
Mark

The constant pressure is a dead-giveaway.
You have a small head-gasket leak. The coolant is going out your
tailpipe, but not in large enough quantities to be obvious. Are there
especially large quantities of white smoke (steam) and a slightly sweet
smell from the exhaust when you start up in the morning?
Not much to do about it other than save your pennies toward the
replacement. Keep a sharp eye on it however... it will only get worse
and sometimes suddenly.
At a guess ~150,000 - 200,000km?

The head gasket was my biggest concern, but I really don't want to fix this
right now. Not quite the Christmas gift I was expecting.
I haven't noticed excess exhuast steam, but it's been cold around here, so
it's hard to say. It did seem to be a bit more than usual when I started it
last night, but I couldn't smell the telltale exhaust sweetness.
I had also taken the cap off the coolant system and made sure it was not
pressurized, and then started it and ran it for 2 minutes. There was
pressure on the system after just that time, so I started to suspect exhaust
pressurization in the system.
The problem has slowly gotten worse ever since a heater hose went a few
months back, so I suspect it overheated at that time.
Thanks for your response,
Brian

Everyone seems to like the most expensive problems most...
More things to try to verify a head gasket leak. Any bubbles from the
coolant after 2 minutes? Check the plugs. When I've had coolant leaks,
even slow ones, into the intake on other vehicles I could see the
coolant deposits on the ones in the cylinder where the leak was. The
location probably won't help you much without opening the engine, but at
least it verifies that's where the coolant is going.
It's still worth checking the cheaper, easier stuff.
I don't know much about this sodium silicate stuff, but the old rule of
thumb was if it'll plug a leak, it'll plug the system too. 'Course, if
the alternative is to open up the engine anyway...
