hey BLUDGER.....with the whole coolant ruins water pumps i can and cant agree. i agree that not changing the coolant will somewhat determine the lifespan of the water pump but having been a mechanic for almost 15 years now i see cars that are 1-2 yrs old that require water pumps replacing due to premature wear. Namely Holden alloytecs are what i see. so for me id have to disagree on the whole keeping the coolant up to scratch to save your water pump. Youd also have to take into account that waterpumps run bearing and seals in them and it only takes a car to overheat good and proper to harden the seal in a waterpump and cause it to start leaking!! Im just talking from personal experience over my time as a day to day mechanic! not pun intended to anyone and not trying to sound like a hot head!

no problem m8.

I'm just a nobody that gives my own personal experience.

so your 15 years as a pro > me.

personally I'm in two mind.

if on a budget and it's still goos, then leave it.

if money don't matter so much then replacing it while the timing belt is out is a good idea too.

either way works for me.
