Want this question answered?
It depends. The explorer has a front timing chain and rear timing chain assembly. While the rear cassette/tensioner rarely fails, it is far more expensive and difficult to fix. If the front tensioner is the problem (which it commonly is), then the repair is quite simple. Either way, a dealership will charge an arm and a leg to repair. I have heard that fixing both can be as much as 2-3 thousand dollars.
yes it has nothing to do with the timing
The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray
there are two tensioners, the serpentine tensioner and the timing belt tensioner. the timing belt tensioner is behind the timing belt cover ;)
Not unless the bearing in that pulley is noisy or rough when you spin it.
chain. if you hear a clattering noise the timing chain and timing chain tensioner need to be replaced they are usually sold as a kit
The 98 explorer has three timing chains. The front two can be replaced by removing the fan, fan shroud, serpentine belt and water pump. The rear chain can not be replaced unless the engine is pulled from the explorer to gain access.
Yes, the BMW M20 engine uses a timing belt. It should be replaced (along with the tensioner) every 70000 kM.
A 1997 Ford Explorer , 5.0 litre / 302 cubic inch V8 engine has ( 1 ) timing CHAIN
All these here should be replaced as per post somewhere else: timing belt, water pump, tensioner, tensioner pulley, and idler pulley
Idler and tensioner pulleys, cam and crank oil seals and pays to do water pump also if it is driven from the timing belt.
This truck has a timing chain, not a belt. The chain will last longer than a belt and should not be replaced until it fails.
