Random Coolant Loss???
« on: 28 March 2008, 14:17:22 »
Hi fellas,
I have a '97 V6 manual that suffers from random coolant loss.
It is so random, that if I had hair, I would pull it out!
I sometimes have to top the coolant up after 40 or 50 miles & sometimes it will be fine for 1000 miles!! There seems to be no pattern at all & this confuses me.
I've fitted a new expansion bottle, the old one had a hairline crack around the filler neck, & I've pressure tested the cooling system 3 or 4 times now, with no pressure or water loss.
This problem has been around for over a year now & is really bothering me.
The temp gauge has never gone over 95 degrees C and I'm sure the head gaskets are fine.
Twice I have seen steam appear from under the glove box area & occasionally the screen will suddenly mist up very quickly, mid journey, accompanied by the horrid hot water/anti-freeze smell. When this first occurred I put some paper in both footwells & left the car running for nearly two hours. NO overheating, NO water on the paper & NO dampness on the carpets which makes me think that the heater matrix is okay.
Sorry about the essay & thanks for reading this,
please shed the light,

Slime.

Have you checked the HBV at the rear of the engine???
There is a guide with pictures in the Maintenance section.

you could try and place a peice of kitchen roll around it and take it for a short drive / run it for a while, then removee the kitchen roll and if its wet its leeken.

not sure it would work but its worth a try.
the lads might have some ideas.

They're not too expensive to replace. £25/30?

The HBV is a little easier in that you can at least see the bugger when the scuttle is removed. The first I saw of my DIS pack was when the final bolt had been removed.  ;)  ;)  :y
