get a book at your local autoparts store!... this will be helpful for much more than changing a timing belt... there are many intricate steps and alignments that MUST be exactly followed to allow your car to run without MAJOR damage after the belt has been changed... and will require special tools including air impact, etc THIS IS NOT A JOB FOR A BEGINNER!!!
I dont agree that you need an impact at all it is very simple as you approach most of it through the wheel well. You can even leave the tire on just turn it to the left. Once yo have the alternator out just take off covering in wheel well you will see everything clearer then. Hardest trick is alternator in whole job. You should put in new water pump while your there.
yes
if im not mistaken..it is behind the timing cover..it runs off the timing belt You are correct. It is the belt tensioner for your timing belt and a pain to release to release the tension and also not the easiest to replace.
Front of engine (behind serpentine belt).
Timing belt replacement is a pretty big job. I'd go to the parts store and pick up a Chilton or Haynes manual.
To replace the timing belt on a 1992 Pontiac Sunbird, first disconnect the battery and remove any components obstructing access to the timing cover, such as the alternator and air intake. Next, align the timing marks on the crankshaft and camshaft to ensure proper timing, then remove the old timing belt and replace it with a new one, making sure it is tensioned correctly. Reassemble all components in reverse order, reconnect the battery, and start the engine to check for proper operation. Always consult a repair manual for specific torque specifications and detailed steps.
Mine did this and I found out it was the timing belt that needed to be changed.
Check autozone.com it tells a bit about it. some engines you have to remove the timing belt so its not a very east job.
Sunburst?
After you have released the tension from the belt, remove the 2 obvious bolts that hold it to the engine block.
I've been informed it has a timing chain, not belt, and therefore does not need to be replaced.
I don't know the cost as that depends on where you live, but may I give you some advice. As the water pump is driven by the timing belt, if this car has over 100,000 miles on it, replace the timing belt at the same time as the belt. This will save you money down the road when the pump fails. The belt should be replaced every 60,000 miles.
If it's like my '91 model its behind the timing belt cover. If you look between the alternator pulley and the timing belt cover you can see part of it. It wouldn't be fun to replace. I think the shop charges 3 to 4 hundred.
