heres why coolant is so vital in the longetivity of your engine,pic of waterpump shows heavy deposits of rust and muck that accumilated,the car in question,kept overheating obviously there was no waterleak,so only way was to strip it down,almost all water channels were clogged in the block and in turn buckled the heads aswell ,so just because you dont have a leak,does not mean your z wont overheat,use antifreeze :headvswal ;) Excuse the pic quality,camera phone :o

Ouch! that looks expensive

More examples :(

 

I think that Nissan state that distilled or deionized water should be used, with antifreeze, a bit more expensive than tap water + antifreeze, but as Greg’s picture shows worth it!

 

I should have taken a picture of mine during the cambelt change, 70,000+ miles and spotless, almost like a new, even when looking into the engines water channels leading away from the pump.

there you go see,with decent levels of coolant through-out the cars life,it saves the engine rusting inside-out ;)

Due to a recent leak while I was in town, my Z now runs on Marks and Spencers Chilled Still mineral water!!! With a healthy dose of antifreeze too, of course ;)
