Water comes out of the expansion bottle

Hi everyone
I have just purchased a freelander 1 1.8 petrol and when it gets warm water is being forced out of the expansion bottle, could anyone give me a clue why this is happening, I'm not sure if the cap is faulty as it spins when I tighten it up as though its on a clutch is this right, and it looks like there's a thermostat thingy in the cap what's that for.
Any feedback would be greatly appreciated
Dave

I've never come across a cap that spins, get a new one and take it from there. Not sure where you'll get one before Tuesday though

Replace the cap as Kermit said , check the thermostat is opening and the radiator isn't blocked ........be prepared for a blown headgasket

Cheers for the replies, all the pipes get hot when warmed up, I was thinking of getting a new cap as I've never known a cap to spin either but wasn't sure as I've not had a freelander before

The cap has a torque limiting override clutch. This is designed to prevent over tightening of the cap. If the cap is sealing, then clicks, its a good sign its sealing ok.

If it holds pressure, then suddenly vents out coolant after a while, it's potential a HG issue.

It doesn't click just spins when tightend down, hopefully not the head gasket

Replied twice

Click to expand...

Replace the tank and cap, the tanks crack, but replacements are cheap.

Thanks for all the replies, off to get a new bottle and cap tomorrow when they open again
