I have been told that a time chain or belt should be changed after about 100,000 mile or 160,000 kilometres and that this is an high-quality service.

First, what is the difference between a time chain and also a time belt and secondly, i am considering the purchase of a 2005 Lexus RX330 the belongs come a neighbour and friend. He bought the Lexus brand-new and takes very an excellent care of his vehicles therefore I recognize it to it is in in wonderful shape. However I"m worried because it is coming up ~ above 150,000 km and, although it still looks prefer new, the possibility of having to shell out thousands because that a significant service (timing belt change) has me wonder if that is worth it. - Mark

As the belt or chain i do not care worn over time, the time of the valve movement can change slightly. But the more important issue is wear. If the belt or chain were to break, the valves would nearly certainly come into call with the height of the pistons, leading to catastrophic damages requiring a complete engine rebuild or replacement. The expense of no replacing the time belt or chain might thus be substantially greater.

A couple of engines usage gears because that this duty but the vast bulk use chains or cogged belts. Belts are slightly less noisy, lighter and also require no lubrication.

Gaining accessibility to that cover calls for the remove of assorted items, regularly including the radiator, various belts, hoses, pulleys and pumps.

If the owner has not currently had this business performed, you have the right to expect to salary in the vicinity that $1,000 to $1,200 - this amount have to be bring away into consideration when make an sell for the car.

Call around to a couple of Lexus and Toyota company departments - you plenty of find one where company is slow and it is supplying specials.
