2003 Mitsubishi Eclipse Q&A
2003 Mitsubishi Eclipse Question: Is it necessary to change the oil when you replace the water pump?
I believe that my car already had a blown head gasket when I took it to the shop and the mechanic was negligent in doing a thorough inspection ( top radiator hose swollen to almost burst, gurgling in radiator) and reported that I needed a new water pump, which he replaced. He claims I was 2 quarts over limit on oil ( which I believe was coolant leaking into oil) and he changed the oil. Is that normal to change oil when u replace water pump? Also, shouldn't you replace thermostat a the same time? - sandibeneke
yes you should repl thermostat w head gasket and it may b over full on oil due to blown head gasket if it wasn't changed at that time,but should have been. i would keep an eye on oil level as you still may have a headgasket or cracked head issue - globalhelper
