How to adjust the seepentine belt on the 1988

1987 Chevrolet Celebrity Serpentine Belt Routing and Timing Belt Diagrams

I had to replace the belt on a 1988 Buick Century (similar to the Celebrity, but with a four-cylinder engine). I found that the only tool that could reach the belt tensioner in the limited space was a socket on a breaker bar; there wasn't room for a ratchet, and I couldn't get the correct angle for a wrench. There may be more room at the end of a V-6 The tensioner bolt is one of the larger metric sizes.

Clean all of the pulleys before installing the belt. Verify that the belt tensioner, water pump and alternator bearings are good - no rough spots or slop, and make sure the tensioner spring is good - the tensioner should require some force on the tensioner bolt head to move it, but it should not grind, hang, or have out-of-plane movement (perpendicular to the pulley rotation).

If everything looks good, you can install the belt. The grooved side is on the inside around the grooved pulleys, and the smooth side is on the inside around the smooth pulleys. Make sure the belt is correctly seated on the grooved pulleys. Save the tensioner pulley for last - use your tool to pull the tensioner in against the spring, and slip the belt on over the tensioner pulley. {CAUTION: do not let your fingers get between the belt and the tensioner pulley. If your tool slips at this point, you'd be in a world of hurt.} Take one more look to make sure the belt is centered on all of the pulleys, then slowly release the tool to apply tension to the belt.

On the 6 cylinder it is located on the left side of the engine when look at it not far from the number one cylinder. in line with the bearings and seals on serpentine belt side next to fire wall about 10 o'clock while facing engine standing at passenger side front wheel.O7OUT

ADJUSTING V-Belts Fig. 1: A gauge is recommended, but the belt deflection may be checked using light thumb pressure
Fig. 2: Loosening alternator pivot/adjustment bolt in order to tighten the belt Fig. 3: Apply tension to the belt being careful not to damage the case. While holding accessory in this position, tighten the pivot bolt. Fig. 4: Using a 1?2 in. ratchet, apply tension to the air conditioning belt while tightening the pivot bolt Belts are normally adjusted by loosening the bolts of the accessory being driven and moving that accessory on its pivot points until the proper tension is applied to the belt. The accessory is held in this position while the bolts are tightened. To determine proper belt tension, you can purchase a belt tension gauge or simply use the deflection method. To determine deflection, press inward on the belt at the mid-point of its longest straight run. The belt should deflect (move inward) 3?8 - 1?2 in. (10-13mm). A general rule for alternator belt tension is that the pulley should not be capable of being turned with hand pressure. Serpentine Belt On most newer vehicles, a single belt is used to drive all of the engine accessories formerly driven by multiple V-belts. The single belt is referred to as a serpentine belt. All the belt driven accessories are rigidly mounted with belt tension maintained by a spring loaded tensioner. Because of the belt tensioner, no adjustment is necessary. REMOVAL & INSTALLATION V-Belt Fig. 1: Loosen the component mounting and adjusting bolts slightly
Fig. 2: Remove the belt by pushing the component toward the engine
Fig. 3: Remove the drive belt
Fig. 4: To tighten the belt, pull the component away from the engine and tighten the mounting bolts to specifications
To remove a V-style drive belt, simply loosen the accessory being driven and move it on its pivot point to free the belt. Then, remove the belt. It is important to note that on engines with many driven accessories, several or all of the belts may have to be removed to get at the one to be replaced. Serpentine Belt Fig. 5: Serpentine belt tensioner - V6 engine
Fig. 6: Serpentine belt tensioner - V8 engine
A belt tensioner is used on these models, to maintain proper belt tension. To relieve belt tension, rotate the belt tensioner (using a 15mm socket) to relieve pressure on the belt. With tension relieved, the belt may then be removed from the engine. It is important to note the belt location at each pulley, to assure correct installation, and proper operation of the engine cooling system. A diagram may be helpful in denoting belt positioning. NOTE: Take care not to bend the tensioner when applying torque. Damage to the tensioner will occur. Maximum torque to load belt should not exceed 30 ft. lbs. (41 Nm).

Adjustment
The belt is automatically adjusted by the auto tensioner.

Removal & Installation

1. Remove the air filter housing assembly bolts and the air intake tube.
2. Remove the air filter housing assembly from the vehicle.
3. Use a wrench to turn the tensioner bolt clockwise, compressing the tensioner, and releasing the tension on the serpentine accessory drive belt.
4. Remove the serpentine accessory drive belt.

To install:

1. Use a wrench to turn the tensioner bolt clockwise, compressing the tensioner, and releasing the tension on the serpentine accessory drive belt.
2. With the wrench in place on the tensioner bolt, loop the serpentine accessory drive belt loosely over the pulleys.
3. Slip the belt over the tensioner.
4. Remove the wrench from the tensioner bolt and the belt will tighten itself.
5. Install the air filter housing assembly into the vehicle.
6. Install the air intake tube and the air filter housing assembly bolts.
7. Tighten the air filter housing assembly bolts to 53 inch lbs. and nm
