Hi peeps was just thinking do I really need to change the water pump and crank and cam seals when I do the 60k belt change I know this is a high performance 300bhp monster but ave never had to do that on a timing belt change normally just tensioner and belt

 

Don't get me wrong have never worked on a Nissan and as engines go you really don't be wanting to put a foot wrong on this one

 

My gt4 was high performance a mere 220 bbl and that was just belt and tensioner

Its not imperative, unless there are obvious signs of wear or leakage, however, its best to replace what you can, while you have the front of the engine bay apart. You dont want to be taking it all apart again 6 months down the road, when you can get it out of the way in one hit.

Water pump and thermostat not that dear to be honest so for the price, def worth replacing.

Cam and crank seals for peace of mind, while the belt is off and the belt tensioners if they look worn.

Best to speak to JeffTT about the pro's and con's, the guy does it for a living, so will be best to advise.

I think age would be as much a concern as miles. A nigh on 20 year old water pump might not have much more go left in him.

aye, ad do the pump as a bare minimum
