How to Change the Drive Belt on a ZD30by John Johnston
The Nissan ZD30 is a 3-liter engine available in turbo, variable geometry and non-turbo versions. The drive belt is used to link two or more rotating shafts within the engine. If your drive belt becomes damaged it can cause your engine to no longer work as it should. When this occurs you should look to remove your drive belt from the engine in order to change it with a new one.
Locate the drive belt on your engine. You will locate the belt by looking at the engine and following the belt which moves around all of the rotating shafts on the engine. This belt is the drive belt.
Use a wrench to remove the mounting bolts attached to the alternator. Lift the alternator and its bracket away from the engine.
Locate the drive belt tensioner. This fixes the belt tightly in place in the engine. Use a nut driver to loosen the bolt which is attached to the tensioner. This will loosen the belt on the tensioner and allow you to remove it. Lift the drive belt away from the engine.
Take the drive belt to your local auto parts store in order to pick up a replacement. It is best to take the drive belt which you removed from the engine as it will guarantee that you get the right size and type of drive belt which you will need for your engine.
Place the new drive belt on to the drive belt tensioner. Tighten the tensioner bolt with a wrench to fix the belt securely in place. Reattach the alternator and its bracket. Fix them in place with the mounting bolts.
