Please, Please!!! Has anybody who owns a ford ka or any other car had a problem with a leaking coolant reservoir? Its driving me balmy! Its a 2004 reg. I've seen the leak with my own eyes. its comming from the bottom of the reservoir. The trouble is: its is only noticable in the morning when its cold. I can see the trickle. but when i take it to the garage. they can't find the leak. Although They agree the level is down and have said the reservoir maybe split.. Anybody got any suggestons what should be done? for instance: replacing the reservoir! Anybody got any idea how much that would cost?
