OK, then make sure there is enough tension on the belt. If there is , then go down to the autoparts store and get some stuff you can spray the belt with to make it sticky. Just tell them whats going on and they will know what you need. You could have gotten some oil on the belt.

On a SC300 there is absolutely no need to remove radiator/fan/shroud to change out serpentine/drive belt. Serpentine belt change can be changed in about ten minutes without removing ANYTHING except the old belt itself. I have put about 200,000 miles on my SC300 and have changed that belt aleast a dozen times. SC400 may be different.
any other question, can I change drivebelt tensioner assembly (that's the part that I brought) without removing radiators, fan, etc... I don't have enough tools... -__-

Just "fish" the belt around the fan blade. If the belt is old/damaged and your still having trouble, just cut the SOB. You will need a socket set with extensions to remove the tensioner pulley. When putting on new serpentine belt, you will need the proper socket and socket wrench(to clear fan blade) WITH a small cheater bar attached(say about 16") to allow the necessary leverage on the tensioner to install belt. Watch your fingers! (Remember, the SC300 engine is just darn near the easiest modern 6 cylinder engine to work on) Very easy procedure with the correct tools to change the belt. I believe you can remove tensioner without removing the fan/shroud.If installing a new tensioner pulley, then,Do Not overtorque the tensioner pulley mounting bolts! Stick with the OEM torque specs, always.

if you never done either then get someone that knows what they are doing to do it for you or help you do it. it is NOT hard to do either one but it is very easy to screw it up...at least the timing belt and if you screw it up then you will most likely need a new motor if you bend some valves. 
good luck
good luck
serpentine belt takes 5 min tops and is cake walk just remember the belt routing

does anyone know how to read the markings on the serpentine belt tensioner? i see 3 lines on the tensioner assembly, but i don't see anything to line them up with like on the block or anything.. just curious my tensioner seems fine but it's really close to another pulley..

So I just removed my serpentine belt. I didnt understand what people posted and finally I figured it out. It was so simple, I wish someone just explained it better. Just tighten the pulley the tensioner is connected to and it swings and you can take the belt off EASY. Geez. Took me 1 min after I figured that out. I used a breaker bar to tighten the bolt.

I did my timing belt when i first purchased my car. It's not very hard, really not hard at all. The biggest pain in the A$% for me was trying to get the crank nut off. Unless you hang out with the Incredible Hulk and he has a 5k lb/ft impact gun your going to have fun.
And as stated earlier in the post make sure to replace anything/everything maintenance related that you can get to when its off. I did'nt and now I have a blown headgasket due to a sticking t-stat
Good luck in your ventures and may the bolt loosening force be with you.
