Drive belt replacement

[Schulmann]

I have to replace the water pump/Alternator drive belt.
I am looking for the tensioner. Where is it located ?

If you are staring at the engine from the front, I think it's the left most pulley. Off the top of my head, you'll need a 15mm wrench, I use a gear wrench, works great. While you are at it, put in smooth tubes

Thanks ! Actually I have discovered it at 11PM yesterday evening after having observed the engine during 2 hours.

So for those who are new in Viper business (like myself) the process to replace drive belt (on ACR 2000 model) is :
1. Remove air filter
2. Detach but don't remove oil cooler
3. Observe how the belt is routed so it will be easier to place it back.
4. Take a 15mm wrench and move the tensioner pulley upward. The tensioner pulley is the one on the most right and most bottom.
5. Check for any damages on the pulleys. My ACR has only 5000km but the belt was damaged. Actually I have discovered a large cut on the Crankshaft pulley. How it happened ?!! So I took a small file and smoothed that cut. The pulley looks good and smooth. I will have to check for vibrations at high RPM.
