    Coolant

    Hi all,

    Got the 1.7dti and it seems to have drunk a little bit of water about 5mm. There is no crap in the header tank or 'mayo' in the usual place.

    The van runs about 86 on the temp gauge and never goes any higher.

    would this be a problem? The time span is a week for it to do this.

    5mm seems very little to me. If yer worried get it pressure tested or get the coolant emissions tested

    Well this is after 400 miles. It doesn't heat up quickly, runs fine etc.

    I've only have the van about 2 weeks, maybe I am being a bit paranoid.

    I am compairing it to my last car, which never used any water.

    Do Astras go through a bit of coolant every now and again?

    First of all make sure you have no leaks. Follow the coolant hoses around. I found one on my red wreck (rover) and the bottom of a hose had split. Replaced hose and all is good again. Get the engine really hot and let it idle then go check out the coolant hoses to make sure there are no leaks. Try and park it on a pavement that is dry and when you pull off again check for any water that wasn't there before.

    If nothing can be found then you may want to take it and have it pressure tested to make sure your head gasket isn't going. If it is save up and get it done. I was talking to my mate who runs a garage and he says the 1.7's are pretty reliable.

    Hope this helps

    Not really TBH, its a pressurised system blah blah so you shouldnt lose any really. Just keep an eye on it is the best thing, IIRC the 1.7DTi is notorious for the head gasket. The above mentioned tests shouldnt set you back more than £30 im sure

    MIne lost a small amount of water at first. Then more and more.

    The reason was a slighlty warped head and corrosion around one of the cylinders causing an eventual consistent misfire (3 cyls) due to lack of compression in cylinder 2

    This caused the head gasket to go very slowly, losing more and more water over about 3 months

    get it checked out because it aint a cheap repair!!!!
