How do I solve a problem with Xara Picasso cooling system?

Just to complete this item (sorry it has taken so long!) but it should be noted that the problem was in the cap for the reservoir. The original cap had lost the capacity for completely sealing the system. Replacing the cap it little cost, solved the problem. There was no evidence when inspecting the cap that it was the cause. After months of driving many miles, including towing a caravan, there has been no loss of coolant.

a friend of mine had the same problem turned out to be coolant hose had been rubbing/chaffing on the engine and caused a pin hole in the hose. hope this helps.

you could try putting car on ramps, start car until up to temp, and look for leaks, and check radiator, if nothing found then i would suspect coolant going into engine, as there is nowhere else for it to go.

helpful?
