General description of the diesel engine power system The diesel engines installed in the Golf II/Jetta II vehicles can be either naturally aspirated or turbocharged. High pressure fuel pumps can be installed in power systems...
Fuel filter service The fuel filter must be replaced every 30,000 km. Additionally, condensate must be removed from the filter after 12 months. The filter is located in the engine compartment next to...
High pressure fuel pump banners (injection pump) To adjust the injection advance angle, as well as to replace the injection pump, special tools are required. This applies to both Bosch and CAV equipment. Before removing the...
Checking and adjusting the compression torque (Bosch pump) Adjustment of the start of compression is always carried out after the installation of the high-pressure fuel pump or after the detection of improper operation of the injectors....
Checking and adjusting the compression torque (CAV pump) An indicator and special mandrel 3071 are required to check the start of compression. The pump is correctly adjusted if the 1st cylinder is at TDC (pic. 243) notch 1 on the pulley...
Accelerator thrust adjustment Manual Transmission Fully depress the accelerator pedal and lock it in this position (like laying a brick). Check if the lever on the injection pump rested against the limiter...
Trigger Adjustment The adjustment of the starting device, or rather the length of the cold start accelerator thrust, is the same. for Bosch and CAV pumps. If the rod has been removed, it must be...
Idle speed adjustment Bosch injection pump For adjustment, the cold start accelerator rod must not be extended, all electrical consumers must be turned off, and the engine warmed up. The idle speed...
Maximum speed adjustment Bosch injection pump Warm up the engine. Set the pump lever to the maximum speed position. Connect the tachometer according to its instructions. Weak locknut and turning the...
Nozzle replacement Injector inspection and repair. must be carried out at service stations. These works cannot be performed independently, since, in addition to the need to use special equipment,...
Turbocharger replacement The individual components of the turbocharger are shown in fig. 259. The sequence of actions for dismantling this device is as follows: Pic. 259. Turbocharger components: 1 -...
Turbocharger Installation Install the turbocharger and tighten the exhaust manifold mounting bolts (it is still possible to move the turbocharger housing). Tighten the four turbocharger mounting bolts to...
Turbocharger check If the turbocharger stops working properly, it should be replaced as it cannot be repaired. The main condition for the correct operation of the turbocharger is the complete...
Replacing the intake and exhaust manifolds Fastening of inlet and final manifolds is shown in fig. 261. Before removing the manifolds, remove the turbocharger. The exhaust and intake manifold gaskets must be replaced with...
Starter candles Starting plugs are auxiliary starting devices and serve to initially heat the fuel mixture on a cold engine and initiate the combustion process. Starter plugs cannot be repaired...
Exhaust manifold replacement Fastening of a final collector in system of release of the fulfilled gases is shown in fig. 264. To remove / install the elastic plate, a special tool is required, the use of...
