Lads quick question I changed the oil pump and timing belt the other day but haven't drove much since went out this eve did bout 50 miles and stopped in petrol station noticed a bit of water on the exhaust under top rad hose side of engine but Couldn see where it was coming from as it was pissing rain so wasn staying out all night looking drove home and noticed car started ta cool down ... Well temp needle dropped any way but still had heaters fairly hot but noticed when I stopped at lights the heaters went cold light went green so drove off and heaters went hot again..... What ya reckon???was thinking water pump????
