"foamy"? Never heard of that one before. If it's bothering you, have you tried flushing?

I would like to know what's going on with your car aswell. Never heard/seen coolant go 'foamy' before.

capuccino coolant? thats what my navara with the blown head gasket does....its air getting into the coolant from the cylinder. If you leave the radiator cap off when running, once the thermostat opens you will probably see bubbles moving through the coolant as well.

It won't necessarily run hot until you have lost enough of the coolant.

Leakdown test could confirm.

Or just chuck a bottle of chemiweld in the radiator....

I agree with Duncan - Headgasket is leaking if you've got bubbles in your coolant.

Chemiweld is a bit of a band-aid solution but i'd be looking at getting the gasket replaced if you value your engine.

cheers guys. well i just took it for a drive, was fine, but wen i got home i checked everything and one of the hoses has blown at the back of the head. it is a spraying sort of leak so must be a small hole in the hose. i blew the top radiator hose about a month ago and changed it without changing the rest of them could this have something to do with it? if its a blown head gasket, what must be done to rectify, there is no water in the oil or oil in the coolant by the way. my car is goin in to the workshop for turbo fitting,pfc ect ect in 3 weeks should i get it sorted then??
