The 1997 Isuzu Trooper was available in three trim levels: S, LS and Limited. All three were equipped with a 3.2-liter V-6 engine that produced 190-horsepower and 195 foot-pounds of torque. The 1997 Isuzu Trooper engine utilizes three different belts to propel the belt driven engine parts. The tension on the belt is controlled by the swivel mounting bracket on the power steering pump. Adjusting the power steering pump will tighten the serpentine belt.

Instructions

Power Steering Belt Adjustment

1

Open the hood on the Trooper and set the hood prop. Position your body near the power steering pump, in the front of the engine compartment.

2

Loosen the power steering pump swivel mounting bolt on the bottom of the pump using a ratchet and socket. Loosen the power steering pump adjuster bolt on the adjuster plate. Push the power steering pump upward using a small pry bar between the pump housing and the engine block if needed. Tighten the adjuster bolt while maintaining pressure upward on the pump.

3

Tighten the adjuster bolt to 34 foot-pounds using a 1/2-inch-drive torque wrench and socket. Tighten the bottom pump swivel mounting bolt to 34 foot-pounds.

4

Step to the drivers side of the truck and start the engine. Press the gas pedal slightly to increase the engine rpm. If the belt still makes a noise, inspect the belt tensioner plate. If the adjuster bolt is at the limit of its adjustment and you still have a belt squeal, the belt needs to be replaced. If the belt noise still exists and you have room for more adjustment, tighten the belt by repeating steps 2 and 3, until the belt squeal goes away.

Alternator Belt Adjustment

5

Loosen the fixing bolt and the lock bolt on the alternator using a ratchet and socket.

6

Rotate the adjuster bolt in the side of the adjuster to add tension to the alternator belt. Tighten the fixing bolt to 16 foot-pounds and the lock bolt to 17 foot-pounds, using a 1/2-inch-drive torque wrench and socket.

7

Proceed to the drivers side of the Trooper and start the engine. If the alternator belt still produces a squealing noise and the adjuster is set at its maximum adjustment, the belt needs to be replaced. If the belt makes a noise and there is more room for adjustment, readjust the belt using steps 1 and 2.

Air Conditioning Compressor Belt Adjustment

8

Loosen the lock bolt on the tensioner assembly. Rotate the adjuster bolt to tighten the tension on the A/C compressor belt.

9

Tighten the lock bolt to 37 foot-pounds with a 1/2-inch-drive torque wrench and socket.

10

Proceed to the drivers side of the Trooper and start the engine. If the air conditioning belt makes a squealing noise, shut the engine off and readjust the belt tighter using steps 1 and 2. If the tensioner is set to its maximum outward position, the belt needs to be replaced.

The new generation of the Volkswagen Passat was first introduced in 1998 on the North American market. The vehicle shares the same platform as the Audi A4 and features a 1.8L Turbo engine that has an output of 168-brake horsepower and 225 foot-pounds of torque. The timing belt is a crucial part in every engine and requires service and replacement if it fails.

Instructions

Removal

1

Bring the lock carrier into service position. Remove the tensioning element for the ribbed belt and the upper timing-belt guard. Mark the direction of rotation of the toothed belt.

2

Adjust the camshaft to top dead center (TDC) at the first cylinder. Remove the harmonic balancer/belt pulley. Take out the lower- and center-toothed belt guard.

3

Thread the T10092 tensioning bolt into the tensioning device for the toothed belt. If necessary, align the pressure piston before tensioning, using needle-nosed pliers or a thin wire (the hole in pressure piston and hole in housing must overlap). Tighten the pressure piston only far enough so that the pressure piston can be secured using a T40001 pin.

4

Insert a V.A.G 1331 hex torque wrench into the hex socket, and torque the tensioning roller nut in counter-clockwise direction with uniform non-excessive force until the toothed belt can be aligned with the mark on the cylinder block. Use the T10008 locking plate to lock in place the roller. To loosen toothed belt, loosen the nut of the tensioning roller by turning the wrench in the clockwise direction. Remove the timing belt and then turn crankshaft back slightly.

Installation

5

Align marks on the camshaft gear and the cylinder head cover. Pistons must not be positioned in top dead center (TDC) position. Install the timing belt on the crankshaft gear (note the direction of rotation). Install the lower timing belt guard.

6

Install harmonic balancer/belt pulley using new bolts. Tighten the bolts applying 7 foot-pounds of torque, plus an additional 1/4 turn. Rotate the crankshaft until the first cylinder is in the top dead center (TDC) position. Install the timing belt in the specific order. First, position the belt on the coolant pump, and then on the tensioning roller and, finally, on the camshaft gear.

7

Tension the timing belt by pulling out the T40001 pin and unbolting the T10092 tensioning bolt. The engine shouldnt be more than hand warm. If the timing belt tensioning device is completely extended, it must be pressed back in the installed position with the tensioning roller. This procedure can take up to five minutes. Excessive force during compression can damage the tensioning roller.

8

Turn the 3387-pin wrench in counter-clockwise direction until the T10008 locking plate can be removed without tension. Turn the pin wrench clockwise until a drill bit can be pulled through the tensioning lever and the housing of the tensioning device. Hold the tensioning roller in this position and tighten the securing nut of the tensioning roller, as you apply 20 foot-pounds of torque. Turn the crankshaft two rotations and check whether the camshaft and crankshaft marks align with their erence points.

9

Install the timing belt guard, the center and upper part. Install the tensioning device for the ribbed belt. Tighten it to 19 foot-pounds. Install the ribbed belt.

The Nissan 200SX is one of the many editions of the Nissan Sentra that have evolved over the years. The Nissan 200SX utilizes the serpentine belt system to turn various components of the engine, such as the air conditioner and the water pump. Depending on the exact make and model of your 200SX, the number of components driven by the serpentine belt can change, but the overall removal and installation process is the same. Change the belt when it begins to fray and stretch to keep your vehicle running smoothly.

Instructions

1

Park your Nissan 200SX in a flat, level area such as a garage, where you can keep your work area secure. Set the parking brake and allow the engine to cool. Release the catch for the hood and open it to expose the engine. Look for the serpentine belt configuration diagram on the shroud cover for the radiator or on the underside of the hood. Disconnect the negative battery lead with the adjustable wrench and set it aside.

2

Locate the belt tensioner pulley referenced on the diagram under the water pump hose in most 200SX models (your particular year/model could have it placed differently -- use the diagram to find exactly where it is on your Nissan). Slot an appropriate socket over the end of the nut that protrudes from the side of the tensioner pulley and attach the ratchet to the socket. Turn the pulley in the direction indicated on the diagram to loosen the pulley. Remove the serpentine belt and allow the tensioner pulley to return to its original, closed position.

3

Remove the belt from the other pulleys in the engine. Refer to the diagram chart to install a new belt. Start with the crankshaft pulley and attach the notched sections of the belt to the corresponding pulleys and match the smooth sides of the belt with the smooth pulleys. Work your way up to the tensioner pulley and use the ratchet to "open" the pulley. Slide the belt over the pulley and let it close again to tighten the belt.

4

Start the engine of your Nissan 200SX. Let it run for several minutes and listen for sounds of the belt screeching or flopping. Allow the tensioner pulley four to five minutes to adjust the tension on the belt before driving.

All cars are fitted with the standard shoulder belt. This belt goes over the shoulder and lap, offering maximum protection for the passenger. Seat belts do become subject to casual wear and tear; sometimes they can stop working altogether, making it dangerous for the driver and passengers. Fixing a problem with a seat belt buckle involves dismantling the seat belt.

Instructions

1

Fully extend the whole of the seat belt to check for kinks.

2

Remove the bolt underneath the seat belt buckle. Hold the retractor straight and thread the seatbelt out. Remove the seat in the car if you need to gain a closer inspection of the belt.
