Title: Coolant Leak & Wet Carpets
Post by: sdgibbon on 21 July 2011, 13:56:43
I have a 1998 3.0 V6 Elite Saloon, and have recently had the coolant level warning come up.
I top it up and in a day or so will need to do so again.
The driver's side carpet (front & rear) are soaked, to the extent that a pool has collected on the rear rubber mat.
I am thinking heater matrix.... any other causes?
I have checked the drains at the front, but not the sunroof, but wouldn't I notice water elsewhere if it was coming in there?

I did the taste test on the pool in the back.... more of a bitter than sweet taste.
I put some wire down the two front sunroof drains and met no resistance, but can't see the two at the back.
I have noticed that although the drivers floor is wet the carpet on the side (console/transmission tunnel) is dry... wouldn't that be wet if it was a matrix leak?
I emptied the water from the rear and will leave the car overnight. With the rain we've been having lately I can tell if it is perhaps the sunroof.

You haven't sampled Vauxhall's pink anti-freeze then.  ::) It's the most foul, bitter tasting thing I've ever tasted. :o

Agreed .. it is REALLY bad ... :( ... I was told, but have no proof, that it is "made" to taste bad to deter cats from drinking any spillage as Ethylene Glycol is extremely poisonous to cats

:(

Well I am sure it's not the sunroof... topped up coolant again this morning, 4 mile round trip, and the warning lights back on and the carpet (rear especially) is soaked.
So, working on the assumption it is heater matrix related, and bearing in mind my mechanical skills are reasonably limited, what sort of possible costs am I looking at?
I have no aversion to getting my hands dirty, I just don't want to get out of my depth.... see what I did there?... water, depth..... whatever!  :)

Sounds very much like it's the heater matrix, and it's a beehatch to sort out  :'(

Had this on the brothers Elite in April ish, if you are lucky it's only the 2 'o' seals which are about 50p ish i fitted new pipes aswell but could have done without them. Took about an hour of me upsidedown with the drivers seat right back and the panel by the fuses out the way for better access and a black bag over the carpet and some rags. if you have to take the matrix out good luck it's a sod. the garage my brother had first asked wanted £600 :o :o :o you can use an allen key to undo the bolt that holds the clamp for the two pipes.

You say the leak is allowing water to go to the back so must be going down the vent plastic so must be the matrix and not the "o" seals :'( :'( you could always remove the centre console and check the vent run to the rear or remove carpits and top up with coolent and run to see if that is the correct way it is getting to the back :y

This sounds more like the heater bypass valve, which is a common problem and an easy fix. However, you still have a coolant leak inside the car, which can only be the heater matrix or the plumbing between it and the bulkhead.

EDIT: Unless there's some bizarre fault where coolant is leaking up the vacuum line from the heater bypass valve. Not even sure this is possible, but you never know.
