you really need to get a manual on the car before you attempt this. Especially the timing belt.. one tooth off and your motor could be history!

the belt timing must be replaced every 120,000 km , the price depend the workshop , aprox 300 dls

There are 2 PDF documents to open from that page (above the picture).
The first (Routing guide) gives you the belt routing diagram code for your car (diagram 6-10).
The 1995 lexus ES 300, GS 300 and Sc300 all have the same engine and belt configuration so refer to the 1995 GS300.

The second PDF (Illustration) shows the belt diagram for code 6-10.

Hope this helps.
Cheers.

it will take an hour to type the step by step of this procedure, your better off getting a repair manual. there are a lot of steps to this procedure and if done incorrectly you could damage your engine. you should consider letting an experienced tech handle this.
