UPDATE: A limited supply of the original best-selling Lextreme 1UZFE EGR Delete Kit remains. If you own a 1UZ from 1990-1997, you really need to get this kit! Email me at [email protected] for help with ordering or questions. This will probably be the last kits I have made.

All other parts are SOLD OUT and won't return, including the LS400 and SC400 turbo kit, rebuild kits, supercharger and performace torque converter. We're not an auto parts supplier and I can't respond to inquries for random Lexus and Toyota auto parts.

How to Change the Serpentine Belt on Your Lexus LS400 and SC400 V8

This is one of the simplest tasks you can do at home and it will about 30 minutes or less.

A Serpentine belt is very important.  It powers the alternator, mechanical fan, A/C compressor and Power steering.  I have an incident that my serpentine belt broke and I lost all power.  Alternator was dead, power steering wasn’t working and so on.  I recommend you should chance this belt once every 50-60k miles.

There are many aftermarket serpentine belt u can get.  One of my all time favorite would be the original Lexus serpentine belt.  The cost is slightly higher, but will worth the money.  The second trust worthy brand would be Gates.  Gates make great quality belts for competitive price.  Here are some aftermarket serpentine belt suppliers.

Gates part number is K060882
ACDELCO part number is CK882
Kragen Brand 6PK22250

The pictures below are very self explanatory.  I tried to give u details explanation.  Right before you take out the belt.  Its belt to use your left on the socket to release the tensor and use your right hand to remove the belt.  I also included a serpentine diagram.
