Dodge Omni/Horizon/Rampage 1978-1989 Repair Guide

Timing Belt



1.7L Engine

The timing belt is designed to last a long time without requiring tension adjustments. If the belt is removed or replaced, basic valve timing must be checked and the belt retensioned.

  1. Remove the timing belt cover.
  3. While holding the large hex on the tension pulley, loosen the pulley nut.
  5. Remove the belt from the tensioner.
  7. Slide the belt off the three toothed pulleys.

  1. Using the larger bolt on the crankshaft pulley, turn the engine until the No. 1 cylinder is at TDC of the compression stroke. At this point the valves for the No. 1 cylinder will be closed and the timing mark will be aligned with the pointer on the flywheel housing. Make sure that the timing mark on the rear face of the camshaft pulley is aligned with the lower left corner of the valve cover.
  3. Check that the V-notch in the crankshaft pulley aligns with the dot mark on the intermediate shaft.

If the timing marks are not perfectly aligned, poor engine performance and probably engine damage will result!

To install:

  1. Install the belt on the pulleys.
