What tool do I need to replace serpentine belt on a 98 isuzu trooper?


This is no job for a novice. Take it to somebody that knows about these. NOT a simple job. You will need to replace water pump and tensioner also. http://www.youtube.com/watch?v=kjhNOVl1Tcc

What else needs to be changed when doing a timing belt on a 1999 honda accord? and about how much should it cost?


Technically, nothing else needs to be changed when replacing a timing belt, however it is recommended or suggested to replace the timing belt tensioner and water pump while doing the belt. These items are only accessable when doing a timing belt. The cost should be under $100.00

On a 98 Trooper is the oil pump acessable when the timing belt is replaced?


Usually the timing belt is on the side of the motor under a cover. And the oil pump is in a different area.

Timing belt jumped... why?


This can be caused by not tensioning the belt corectly.When fitting a new belt you should allways replace the tensioner,and make sure the water pump pulley is in good working order.Its always wise to get your timming belt from the dealer.as others are nown to be faulty.Fit new belt follow manuel when doing so.good luck

Just puchased a 1998 trooper runs loud


It sound like you have a timing belt tensioner that is bad. Is the noise at the front of engine? If it is replace tensioner,timing belt and water pump. The pump is driven by the timing belt.

My 98 eclipse is making a screeching noise in the engine


1.Most likely alternator belt is not tight enough or need new one.2. A/C-Power steering belt is loose or need new one. 3. Bearing in A/C-Power Steering Tensioner is going bad. 4. Not the water pump unless you are loosing water all the time. Timing belt runs the water pump & you need to tear down the engine. If so ,you would need to replace the timingbelt,tensioners, and maybe the hydraulic tensioner. NOT FOR $300, more like 5-600. Get yourself a Haynes Manual for 95-99 Eclipse at AUTOZONE,Advanced Auto, or Pep Boys and read up on this.
