the parts costs depend on the vehicle and motor, it shouldn't be to hard to replace, just be sure the mounting bolts are securly tightened
Since There is no tensioner pulley you have to loosen your alternator.
Loosen the tensioner pulley. The power steering belt will come loose. Remove the power steering belt. Reverse the process to install the new power steering belt.
it depends on the engine. on a 2.8l, the serpentine belt tensioner is below the power steering pump. pay careful attention to how the belt is routed, especially if there is no belt routing diagram under the hood (should be on the belt guard on top of the engine). release the tension from the tensioner, replace the belt, make sure you have it routed correctly, release the tensioner.
Remove the belt by loosening the tensioner pulley. Remove the power steering hoses. Remove the retaining nuts. Reverse the process to install the new power steering pump.
remove belt, remove upper accessory tensioner bolt (shock) remove bolts holding power steering pump and push to side - to get at recessed tensioner bolt. remove lower a/c bracket - front of engine. Remove tensioner bolts and tensioner.
There is an adjuster on the power steering pump. One cannot adjust it as it has an automatic tensioner if the belt is squeaking it is time to replace belt/tensioner or both
The belt tensioner for the AC/Alternator belt is beneath the alternator. Facing the engine from bumper you can see the ac/alternator belt tensioner on the left side and beneath the alternator. Losen that bolt with size 12 socket. Next, loosen the tensioner bolt until the belt loosens. Now, with the Power Steering Belt you can loosen it by locating the belt tensioner usually found inside of the power steering belt on the power steering pump. Loosen both bolts and if needed pry UP the power steering belt tensioner and the belt should loosen. Repeat until belt comes off. Installation is the reversal of removal. NOTE: You may have to pry down the power steering pump tensioner to tighten the belt.
The belt tensioner is located at the bottom of the power steering pump looking at it from the front the tensioner is on the bottom left. you could always loosen the alternator up a little. My 1997 with a 4.0 does not have a tensioner pulley, and I believe the 99s are the same. the alternator is the tensioner. Remove one of the bolts and it will swivel in and you can get the belt off
The tensioner is spring loaded. To remove it is not the easiest of jobs. It is held on by a single 15mm nut. The easiest way to get to it is from under the car. It is located near the power steering pump it is the only nut in that area.
you replace it : )
The water pump does not have a "tensioner".
The tensioner has a spring in it that provides the correct tension for the belt. If it is too loose, replace the tensioner.
