Once the tension is relieved, slip the belt off the pulley then slowly release the tensioner
Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow
the tensioner to snap back, as this could damage the tensioners internal parts. 3.
Now finish removing the belt from the other pulleys and remove it from the engine. 4.
To install:
While referring to the proper routing diagram (which you identified earlier), begin to route the belt
over the pulleys, leaving whichever pulley you first released it from for last. 5.
Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final
pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the
pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the
belt. 6.
Once the belt is installed, take another look at all the pulleys to double check your installation. 7.
Connect the negative battery cable, then start and run the engine to check belt operation. 8.
Once the engine has reached normal operating temperature, turn the ignition OFFand check that the
belt tensioner arrow is within the proper adjustment range. 9.
Timing Belts
INSPECTION
Only the 2.3L and 2.5L OHC engine uses a rubber timing belt. All other engines use a timing chain, and
no periodic inspection is required.
The 2.3L and 2.5L Ranger engine utilizes a timing belt to drive the camshaft from the crankshaft's turning
motion and to maintain proper valve timing. Some manufacturer's schedule periodic timing belt replacement
to assure optimum engine performance, to make sure the motorist is never stranded should the belt break (as
the engine will stop instantly) and for some (manufacturer's with interference motors) to prevent the
possibility of severe internal engine damage should the belt break.
Although the 2.3L and 2.5L engine is not listed as an interference motor (it is not listed by the manufacturer as
a motor whose valves might contact the pistons if the camshaft was rotated separately from the crankshaft) the
first 2 reasons for periodic replacement still apply. Ford does not publish a replacement interval for this motor,
but most belt manufacturers recommend intervals anywhere from 45,000 miles (72,500 km) to 90,000 miles
(145,000 km). You will have to decide for yourself if the peace of mind offered by a new belt is worth it on
