Question From A New Lexus Owner.

[silverstatic]

Does it matter if the timing belt alignment line was moved as i was taking the crankshaft pulley bolt out? Please help. It's a Ls400 91'.

If you screwed up the timing then NO that is NOT ok at all.

For a new Lexus owner, you sure are ambitious. ;)

The timing is very critical and must be lined up precisely.

See the link below for a tutorial on changing the timing belt. Step 34 shows how to properly align the belt.

Any idea how similar/different the process is for a Generation 2 LS400 (1999)? Has anyone done that thorough of a tutorial for a Gen 2?

I replaced my timing belt on my 95 LS 400 4 weeks ago using the same tutorial. I would imagine the timing belts would be the same part# and would have the same line-up marks on them possibly-only way to find out really is to look up the part online. i purchased mine from autozone for $36. good luck!

When it comes to a critical component like a timing belt, I would really (I mean REALLY) recommend a Lexus OEM belt.

Especially if the engine is the interference type. If the belt should break, hello new engine (or rebuilt). Cha-ching.

True story. A friend of mine recently had the T belt of his 2000 Ford Escort SR2 replaced at 80k miles (recommended every 60k).

The shop that did the work used an Autozone belt. At 120k, the belt broke and trashed the engine. I know, thats a Ford not a Lexus,

(so dont flame me). The point is that a lot of replacement parts are inferior (and possibly made in China?...naw). Replacing the belt with

just any brand does not get you out of the woods, so to speak. Use only Lexus/Toyota timing belts.

Landar is exactly right! TB, tensioner, pulleys should all be OEM every time! There are NO vital components that I would be betting on with aftermarket parts!
