I would personally go with the thermostat fella. Sounds like its staying shut. Cheap, easy fix Then if its not that, do the water pump.Water pumps only leak if the bearings fail, they can break up internally (fins break) and you wouldnt get a leak at all, just no coolant circulating. But as i said, do the thermostat, then if that doesnt work, water pump it is! |
