Hi All,
Our 207 keeps loosing coolant.

the car's driven every day and it whips through the reservoir every week.

I'm no mechanic but i'm pretty sure this isn't right.

I recently replaced the mechanical temp valve & sensor on the NS of the engine, the old one certainly was knackered. But the problem is ongoing.

One thing i've noticed is that when up to temperature, there doesn't seem to be any 'flow' through the reservoir which is what I do get on my van (different system design perhaps?), but instead, if the reservoir cap is off then it just overflows - think of a volcano erupting.

Not sure what to try next but really want to sort this.

Would very much appreciate input.

Matt

I should add, head gasket was replaced 12 months ago. Theres no cream on the filler cap either.

Motor mechanics bought a Mini at BCA with a defective engine, turned out the engine had boiled dry because the hoses from the header tank were blocked.
Not sure if this is relevant but I think its the same engine so I would check them out and remove a bottom hose to flush the engine and radiator.
