Are you having to top system up?
Yes but sometimes there is more water in than in before if that makes sense its as tho it usnt moving around the engine
Sounds like there is an airlock somewhere. There's also a chance the coolant tank cap is faulty after reading your other thread, as it may not be allowing the tank to vent the excess pressure build up
So do you not think its the head gasket seems like the water isnt movin round the engine but when i release the cap the level goes back to normal hope it aint the hg
Morning lads,gotta vectra cdti 1.9 06 plate recently been using about half a pint of water a week cant find any leaks ive had it pressure tested and the lad says im losing pressure but only very slowly. He also done a sniff test went from red to a slight yellow he said its the head gasket but he doesnt trust the sniff test coz they are unreliable. If it is the head is there any stuff on the market which i can pour into the header tank to reseal the head gasket . Ive seen a few products but do they work?? And also the temp guage has got a mind of its own goes up and down then stays on 0 then up and down again the water pump was done last month also cheers
