Having problems with your 1998 Chevrolet Astro ?

Vehicle unexplainably ran rough and now won't start

\015 I think my timing belt needs to be replaced, how do I know if it does?\015 Posted / edited by AnonymousUser on : 23-04-2018

Answers :

If it no longer starts, the easiest way to check for timing chain failure is eyeballing the distributor rotor. You'll need a helper.

  • Pull the air filter assembly
  • \015\012
  • Loosen the distributor cap mounting screws. (They won't come completely out) Some distributors have 'half-twist' fasteners that look like screws. With these you push down and give it a half turn.
  • \015\012
  • Pull up on the cap and set it aside.
  • \015\012
  • In side you'll see a round plastic thing with a piece of metal going from the center to the outside. This is the rotor.
  • \015\012
  • Have your helper turn the engine over while you watch the rotor. WARNING: Keep clear of the engine while doing this. It won't start, but it can still cause damage.
  • \015\012
  • Is the rotor turning? If not, your timing chain is broken.
Hope this helps,
