Dissapearing Water/Coolant...
Hey guys....
I have a 96 VS Calais with about 120000 on the clock...
A lil while ago my heater core decided to go and piss coolant all over my floor and hence the car overheated due to no water in the system...
I have since repaired by looping the hose around and making it a closed circuit...
But now...9 months later...the car goes through more water then it does petrol...
i have used stop leak etc...and cannot find any visible water leaks in the engine bay...(although it does like to piss oil everywhere)...
I fill the car up with water...then 2 days later it starts overheating again...and i have to refill....
I looked on the oil filler cap...and there was no milkyness...but when i remove the radiator cap the water is bubbling slightly and does go frothy...
I'm thinking head gasket?? does anyone have any ideas/advice??
thanks guys

Even in our sleep we happen to be right.

Sounds like a headgasket issue.
Do a compression test and/or watch for steam in the exahust pipe once the car has warmed up.
Heater core is a big job and I'm wondering how poorly the cars been maintainted if at 120,000ks its blown the heater core & headgasket?!?

Some radiator places can do a chemical test on your coolant/water to detect any combustion gases - this will tell you for sure if its a head gasket gone.....though which head, left or right?....screw the plugs out and inspect the condition of each - if one/some look suspect with fluffy sooty deposits on them then its that head. Water pump probably will be failing around this mileage/age as well. Good luck.
I'm experiencing a similar problem at present. Lead in circumstances a little different though. Car is 96 VS S1 Acclaim with nearly 99000 on it. Was serviced about a month ago and had the thermostat, housing and top hose replaced. System was flushed also. In the 2wks after that, it was topped up with nearly 2 litres of coolant. So when I had a chance took it back and they looked at it again and was told that the screw on the hose clamp was stripped, which they replaced and would be fine. They were right and for 2wks perfect (checking every couple of days) then yesterday had to top up radiatior and overflow bottle between 1/2 & 1litre all up. Yesterday drove for about 50kms all up then this morning overflow bottle empty again. Do I have a problem or just being paranoid. Oil is clean, no signs of coolant in the engine bay anywhere, no puddles on the ground, no steam. Water pump replaced about 3yrs ago.

There was an excellent post, with pics on how to change the heater core the easy way. I'll see if i can find it.
Here it is: heater core on VS

Forgive me if I don't reply to a query straight away. The E-mail notification function only works 50% of the time for me.
Id replace the radiator cap as well, always a good thing to do if its getting a bit of rust or gunk in it.
yeh im gonna replace thermostat and cap tomorrow and do a compression check to see how it all goes ......
i shall keep y'all posted...
Mine was going through a lot of coolant too, turned out it was leaking at the pump. Replaced the pump and it worked a treat, no more leaking

You've got to remember that the VS radiator runs at 20 psi which is quite a lot of pressure. You only need a pinhole leak, maybe from a tiny split or a hose clamp not properly tightened or a waterpump seal leaking slightly and that coolant will spray out and basically disappear as a mist or steam and leave little trace. Also the coolant is at around 100 deg C which means it boils and evaporates almost instantly. The only leak you may see is when it occurs after the engine is switched off and the leak continues and dribbles down continuously leaving puddles. It always pays to do some detective work and just sit and watch the engine whilst it is running...run your eyes along every surface which has anything to do with the cooling system and look for "something different". Good luck
yer guys...
ran a press test...water pissed outta the water pump...although when running there was no evident leaks etc...
ah well
give it a few more days i guess and shall see how it goes!!
