How to Replace the Serpentine Belt in a Mitsubishi Eclipse

by Contributor

A drive belt is called a serpentine belt when it snakes around various components of the engine. For a Mitsubishi Eclipse, the drive belt setups vary, and there may be more than one belt. This information refers to the model year range of 1995-2001 for the Mitsubishi Eclipse. Since the drive belt setups in the Eclipse vary quite a bit, check your owner's documentation for specific tools, methods and belts.

Step 1

Locate the main component for the belt. This component has a locking mechanism in place that adjusts tension on the belt. An alternator belt generally gets adjusted by the alternator, the power steering belt by the power steering pump and so on.

Step 2

Look at how the belt is routed over different pulleys and make a detailed drawing for later reference. Make sure you have the routing exactly right. The Eclipse has different setups according to the engine type. The 2.0L and 2.4L 4 cylinder turbo models has the water pump as part of a drive belt assembly. On other models, the drive belt is run by the timing belt.

Step 3

Use a wrench to loosen the one or two bolts near the main component to allow you to move the component and change tension on the belt. The power steering pump usually has two mounting bolts, and the alternator has a pivot bolt and lock nut system.

Step 4

Slip the old belt off of the pulleys.

Step 5

Install the new belt using your belt routing diagram. Make sure the belt is routed right and seated correctly on all pulleys.

Adjust the component to get tension back on the belt and tighten the applicable bolts.


  • Mitsubishi recommends checking these belts every 6,000 miles or 6 months for possible replacement.
