paul.h Posted August 18, 2011 Posted August 18, 2011 Some obvious checks which you may have already done include the radiator, cabin heater matrix which may be noticed by smell when hot (similar to burnt curry), all coolant hoses and the air bleed points on the hoses, water pump, expansion bottle cap. These would all be noticed by coolant at the leak point but once the coolant is hot it may evaporate so best to look when still cold. Next is a possible head gasket leak into a cylinder so you may see more water vapour from the exhaust than previously, or a leak to the outside down the engine block. Quote
biggestalever Posted November 9, 2011 Author Posted November 9, 2011 found it.... the air filter box had chafed through a pipe underneath it.. its part of the water intake tank. looks like a right pig to change so I have repaired it .. all good now. Quote
