How to Replace the Timing Belt in a 2004 Volkswagen Passat 1 8T

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.

How to Replace the Fuel Pump on a 2004 S 10 Blazer

The Chevrolet S-10 Blazer was a mid-size SUV manufactured from 1983 to 2005, with the last major redesign occurring in 1995. The 2004 Blazer had a 6-cylinder 4.3L engine with multi-port fuel injection requiring a high-pressure electric fuel pump. The procedure for replacing the fuel pump is the same in all versions of this vehicle. The fuel pump is part of the fuel-sending unit on the fuel tank, so you must remove the fuel tank in order to replace the fuel pump.

Instructions

    1

    Disconnect the cable to the negative terminal of the battery with a socket wrench. Install Fuel Pressure Gauge J 34730-1A to the fuel pressure connection on the fuel rail. Loosen the fill cap for the fuel tank, and open the valve on the fuel pressure gauge. Disconnect the fuel pressure gauge from the fuel pressure connection.

    2

    Drain the fuel tank and support it with jack stands. Remove the filler neck for the fuel tank. Disconnect the fuel tank shield and the retaining straps for the fuel tank. Detach the fuel lines and electrical connector from the fuel pump. Disconnect the fasteners for the fuel tank with a socket wrench and lower the fuel tank from the vehicle with the jack stands.

    3

    Turn the locking ring on the fuel tank counter-clockwise with a spanner wrench. Remove the locking ring and detach the fuel pump from the fuel-sending unit. Discard the O-ring that is on the fuel tank.

    4

    Install the new O-ring on the fuel tank and lower the fuel-sending unit into the fuel tank. Avoid damaging the fuel strainer as this can restrict fuel flow. Turn the locking ring clockwise with a spanner wrench. The cam-locking ring will lock into position under the locking tabs.

    5

    Connect the fuel tank to the vehicle and tighten the fasteners to 33 ft. lbs. with a torque wrench. Attach the fuel lines and electrical connector for the fuel pump. Fasten the restraining straps and shield for the fuel tank. Connect the filler neck for the fuel tank. Connect the cable to the batterys negative terminal. Start the engine check for fuel leaks.

How to Install a Lift Pump on a 2004 Dodge Ram 3500

The Dodge Ram series of full-size pickup trucks is manufactured by Chrysler under its Dodge brand. The 3500 models have a rated carrying capacity of 3/4 ton, although the actual carrying capacity is higher than this. The 2004 Dodge Ram 3500 with a diesel engine uses a fuel lift pump (transfer pump) to move fuel from the fuel tank to the fuel system. The fuel lift pump on this vehicle attaches to the rear of the fuel filter.

Instructions

    1

    Place a gasoline container under the fuel filter separator and turn the drain plug on the bottom of the separator in a counterclockwise direction. Drain the fuel from the fuel filter and tighten the drain plug.

    2

    Detach the electrical connector on the fuel lift pump. Disconnect the fuel line for the fuel lift pump from the inner left frame rail.

    3

    Remove the mounting bolts for the fuel lift pump from the fuel filter, using a hex wrench.

    Discard the O-ring in the housing of the fuel filter.

    4

    Mount a new O-ring on the fuel lift pump, then coat the O-ring with a thin layer of new engine oil. Place the fuel lift pump into position so that it is flush with the fuel filter housing. Fasten the mounting bolts for the fuel lift pump, and tighten them to 61 inch-pounds, using a torque wrench.

    5

    Connect the fuel line to the connection on the inner left frame rail. Attach the electrical connector for the fuel pump.

    6

    Turn the ignition on for two seconds to prime the fuel system, then check for fuel leaks. Start the engine and check again for fuel leaks.
