Hi all,

I have a coolant leak. It is actually leaking from underneath the car when the car is hot. The drops of water /coolant are dripping from the aluminium exhaust surround (heat guard whatever) on the passenger side of the car towards the front, so basically somewhere inbetween the handbrake and the middle of the passenger seat, but underneath.

The car is not overheating, and I would say it is probably losing about 150ml of coolant before it stops dripping.

Could this be a thermostat, or simply a burst pipe somewhere?

The only other thing to mention is that the coolant reservoir seemed to be bubbling slightly from underneath, as if air was being pushed in, and also hissing a bit. It seems to me as a total layman that there is a leak somewhere in the cooling system, but I want to be as clued up as I can before I take it in to get looked at.

Any ideas or help would be much appreciated.

Thanks in advance :)

Paul
