Just curious has anyone suffered a waterpump leak/failure? My car sometimes starts to overheat when idling after the engine is up to temp, which has forced me to fix the slow speed problem. Also, when fitting my fmic, I noticed coolant on my undertray and what seemed to be coolant trailing down the drivers side of the engine which makes me think waterpump? How do I go about diagnosing the problem? Had the coolant light on the dash one morning, so checked level and it was quite low. Topped it up and risked driving from Cornwall to Gloucester and there was no fluid missing after it had cooled down...? Any advice?
