When you replace the AC belt you really should replace the serpentine belt as well, since you will have to take it off already. If you don't do it now it is inevitable that you will have to replace it in like 3 weeks anyway : )
You need to first remove the serpentine belt by loosening the nut in the center of the idler pulley. After that you will need to loosen the push bolt on the side of the idler pulley. The hub bolt is a 15mm size and the push bolt on the side of the tensioner is a 13mm I think. After you loosen it sufficiently, you will need to pull off the old belt.
Next you will need to loosen the tensioner pulley for the AC belt as well. It is the same process. The main issue is space. You will most likely need to raise your car to get at the right angles to loosen these pulleys.
Once you loosen the idler pulley in the same manner as you loosened the other, you can slip the AC belt onto the back of the crank pulley and route it as the diagram under your hood instructs you. Next tighten up the idler pully in the opposite way as you loosend it...tighten up the push bolt until the belt play is within factory specifications, then tighten the hub bolt in the center of the pulley. Do the same for the serpentine belt and you should be up and running in no time. I just performed these tasks on my 2000 300m and I wish someone would have told me this before I started my project. Hope this helps, Good Luck!

Sounds like the timing belt broke. Unfortunately this vehicle was not equiped with no contact valves so if that is the case you will need to have the engine and Head rebuilt. If the crank position sensor can't sense the position of the crank it should shutdown the electrical to keep you from damaging your engine.

Removal & Installation
To install:
To install:
Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.
If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.

Locks up? Do you mean the brakes lock up? If so, it could be a faulty brake module, but first have the rotors checked and look at the caliper to see if is heated up. WATCH OUT! They get REALLY hot if they are sticking and grabbing. Use the back or your hand to feel the heat, but DON'T touch! If it is really hot, then it is the caliper and the only fix is to replace the unit. Change the rotor while you are at it, and inspect the bearing to see if it rolls cleanly. It might also be shot, and the rollers could be failing or falling out. This is a dangerous situation and must be attended to right away to avoid an accident.
