3.2 V6 GTS (PETROL)
Our vectra has been a bit unlucky when it comes to coolant. About 6 months ago we started noticing leaking coolant. At first it was manageble, then it got worse, so decided to give it a fix. Jax (of all places) said its the housing water tap leaking (it was cracked), they changed it and the problem did get better (though not fixed).
However, its starting up again. I have heard of the heat exchanger failing (but thats a scary and expensive problem) on this and other opel forums. I took it back to Jax and they poked around with a camera and concluded it is the heat exchanger. Took it to a Holden dealer (I'm in Australia) and they have said a similar thing.
Any of you guys have this problem? It is getting worse, so would like a solution. Is it a very serious problem that can effect other areas of the car?
LASTLY, I'm in Australia, Brisbane area. Can anyone please recommend any good mechanics to deal with a Vectra if we have some Aussies here? Have had bad experiences with Holden dealers in the past. Euro garage specialising in BMW, Merc, Audi, VW doesnt want to touch Euro Holdens. Any good European/Opel garages/mechanics?
