The 7.3L Ford engines come inside the Ford Excursions and the Ford diesel vans. The 7.3 liter engine comes geared up with a single serpentine belt that controls all of the front engine equipment at the identical time. The belt routes round every pulley in order that when the automobile is working, it will possibly function all of the equipment at the identical time. If the belt is lower, chaffed or has extreme cracks on the inside the belt, substitute it instantly.
Ford Excursions Change the Serpentine Belt Instructions
Open the hood on the Ford car and find the belt diagram. This diagram explains the routing instructions of the belt round every accessory pulley. Use the belt routing diagram when putting in the new belt. The diagram is positioned on the high of the black plastic cowl that surrounds the radiator.
Find the spring-loaded belt tensioner on the front of the 7.3L Ford engine. The tensioner is under the alternator and above the crankshaft pulley. The tensioner has a 1/2-inch drive sq. gap on the pulley finish of the tensioner. Use the sq. gap to rotate the tensioner backwards and forwards.
Rotate the tensioner pulley clockwise with the half of-inch drive breaker bar. As soon as the belt turns into unfastened sufficient to take away, slide it out from the underside of the tensioner pulley. Then, launch the tensioner pulley and take away the breaker bar.
Slide the belt out of every pulley. Then, pull the belt round every fan blade and out of the engine space. Rotate the fan blades as wanted to get the belt round every blade.
Route the new belt round the fan blades and round the crankshaft pulley. At all times start the routing means of a single belt with the crankshaft pulley. Then, route the new belt as directed by the belt routing diagram.
Rotate the tensioner pulley clockwise once more with the breaker bar. Then, slide the new belt beneath the backside of the tensioner pulley. Launch the tensioner pulley and because it retracts, it should pull all of the slack out of the belt. Examine the belt to be sure that it’s correctly routed and that it’s seated inside of every pulley.
Crank the 7.3L Ford Engine and watch the new belt simply to make it possible for it’s going to keep round the pulleys. Flip the engine off and shut the hood.
