XG350 Timing belt at 90,000

[Dan K]

I decided at 60,000 to put off the timing belt until 90,000 on my 2002
XG350, mostly because the car was only 3 years old at 60,000 miles. Well,
its going to turn 90,000 in another month and I'm trying to get a list of
parts togeather. I fully intend to keep the vehicle to byond 180,000 miles.
I know HyundaiTech suggests replacing the hydraulic belt tensioner, why is
this? Have you seen them fail? There are lots of parts that could take out
an engine if they fail...why have you focused in on the hydraulic belt
tensioner? I'm not doubting your thinking, I'm just trying to understand
why you make this suggestion.

plenium gasket - required when back 3 spark plugs are replaced
spark plugs
waterpump - might as well
timing belt
hydraulic belt tensioner
serpintene belt
fuel filter
air filter
tranny fluid for a drain and fill
antifreeze for a drain and fill
Any insights on replacing radiator hoses??
Other??


Thanks

Dan

Your list looks pretty good, Dan.

The reason for recommending the timing belt tensioner is that I have
indeed seen them fail. And if it causes the belt to slip, it can have the
same consequences as a stripped or broken timing belt. It's one of those
cases where I think you're better safe than sorry.

And, at 90k, I think you're correct that the water pump is a good idea.
The timing belt is very labor intensive on this car, and at 90k, your
water pump warranty is just about over. It'd be very disappointing to
need to pay that labor all over again if the water pump started to leak.
