Timing belt change on 2002 lexus straight six cylinder engine.

The RX 330 uses a timing belt. It will be on the outside end of the engine furthest from the gearbox. It will be hidden behind a plastic bolt on cover used to protect fingers from fast moving parts.
The cars with an internal timing setup use a timing 'chain' which doesn't need changing anywhere near as often.

nowhere. it has a timing chain that should last forever as long as you keep your oil in good shape. doesn't matter if you have a 4 cylinder or a v6, they both use chains.

A six cylinder Trailblazer does not use a timing belt. It has a timing chain.
Are you sure you did not cause a problem with the cam or crank sensor ?

This engine uses a timing chain not a timing belt, a timing chain never needs to be replaced unless it fails or the engine is being rebuilt

Both engines .. the four and the six have timing chains.. not belts.. so there is no replacement for the life of the engine.

Some of the six cylinder models did have problems with a Timing Chain tensioner.. if you have the six and it makes a rattling sound when first started..that could be an indicator. There is a TSB (technical service bulletin) on this and it should identify which cars are affected.

Best of luck!

On Honda Accord between 2002 - 2010 all they came with was an 2.4L engine, all have timing chain in them, no timing belt

It has a timing belt. Recommended to be replace every 105,000 miles, timing belt also run's your water pump good idea to also replace, your engine is also an INTERFERENCE ENGINE which will damage your cylinder head valve's if timing belt goes bad. Hope this was very helpful.

If it's anything like the six cylinder engines from Audi, which I'm very familiar with, and from what I remember of the V8, you have a timing belt that drives the water pump, crank, and exhaust cams, and also includes a tensioner and an idler roller. The timing chains come into play in the cylinder heads. What Audi did was to only drive the exhaust cams off of the crank, using the timing belt, and inside each cylinder head there is a timing chain assembly that is used to drive the intake cams off the exhaust cams. On a periodic service (like the timing service) you only need to do the timing belt. The timing chains are only replaced if the tensioners fail - you'll know this by a diesel-like clatter from the cylinder heads. Failure of the chain drive assemblies is very rare, which is good because they're incredibly expensive (on the V6 engines they're upwards of $700 each). If you're doing this job because it's due based on mileage, don't touch the timing chains in the cylinder heads - only change the timing belt, tensioner roller, relay arm, hydraulic tensioner, idler pulley, water pump, and serpentine belt. You can leave the chains alone.

The 2002-2006 Camry received the next generation 2.4L 4-cylinder engine (model 2AZ-FE), which combines decent power with excellent fuel economy. This engine does not have a timing belt, it has a chain that does not need to be replaced.
The second choice is very smooth and powerful 3.0-liter 24-valve all-aluminum V6 engine.
Starting from 2004, the 3.3-liter V6 DOHC VVT-i engine is available on SE V6 model.
Both, the 3.0L and 3.3L V6 engines have a timing belt that must be replaced at certain interval

the 2.7 v6 engine uses a timing chain. no service interval. What engine do you have?
