can anyone help? my astra has sprung a leak which i thought was comin from the thermostat housing,so i put a new gasket on that but it is still leakin and it looks like its comin from just under the manifold flange,the pulley end of the head.will it be the head gasket? and roughly how much are they(hoping they aren`t cozzy prices).many thanks
you sure the hose that connects to the stat hasnt got a split in the bottom where you cant see.
If your water pump is leaking id replace it before it seizes and possibly bending valves,the c20xe ISNOT a safe engine?
