350z Timing Belt Question
Hi,
I am about to buy a 2003 Nissan 350z with 50k miles. The guy has not changed water pump/timing belt yet. Is this something I need to worry about, and how often do the belts on the 350z last?
Please let me know as soon as possible
Thanks
Tom

Let's get the facts straight: the 350Z VQ35DE has a timing chain that should last the life of the engine (or until you rebuild it). There are two engine drive belts (one for the PS/ancillary drives and the other for A/C) and they should be replaced at 60K, if not sooner.

Yep what he said Chains usually run the life of the car the other belts
need to be checked once in a while for cracks and stuff. Read the owners manual and it should tell you when to check what

I'm just curious I guess.

interference engine
I still have as built chains on my 311,000 mile Q engine [new metal guides at 100k] the chains have stretched < 4 degrees relative to crank......nice upper rpm boost above 6,000 thru 7300 rpm and the VVT retard stops the lope one would expect at idle from a domestic with such high mileage.
Unfortunately on the newer 3.5 and 4.5 there is no way to adjust initial to compensate for stretch so maybe replace chains every 150k........whenever the idle gets a little shakey.
With a seperate crank and cam sensor the ecu might throw a code when things get too far out of whack. We'll have to wait a few more years to find out.
