Recommendations for elimination of typical malfunctions of the systems of these vehicles are given.
Golf II / Jetta II cars began to be produced in 1983. Since 1984, both carburetor and diesel engines have been installed on them. Two years later, the Golf turbodiesel model, equipped with a turbocharging system, was added to these cars. Gasoline engines could be equipped with both carburetors and fuel injection systems with various types of ignition systems (see Tab. 1).
Basic modifications of Golf II/Jetta II cars are front-wheel drive, Synchro versions are all-wheel drive with a three-link longitudinal drive shaft and a viscous coupling installed in front of the rear axle.
Front suspension independent, contains spring struts (MacPherson type). The rear wheel suspension is a type of linked-arm suspension. It is formed by a U-shaped transverse beam and trailing arms, at the ends of which spring racks are installed. The rear axle beam is connected to the body by means of two rubber-metal corrective bearings.
Cars of GTD modifications are equipped with anti-roll bars.
The brake system - with disc brakes for the front wheels and drum brakes for the rear - is equipped with a hydraulic drive with two separate circuits. The hand-operated parking brake acts on the rear wheels.
The steering contains a rack-and-pinion steering mechanism; a hydraulic booster can be used in the steering drive.
The cars were equipped with fully synchronized four- and five-speed gearboxes. Models with high-powered engines and an injection system were equipped with only a five-speed gearbox. An automatic transmission was installed complete with a diesel engine equipped with a free fuel supply system.
Typical malfunctions due to the design features of Golf II / Jetta II cars include the following:
- engines with a working volume of 1.3 liters can be difficult to start in winter due to freezing of the carburetor;
- in gasoline engines, increased oil consumption may be detected due to the poor quality of the oil seals;
- in diesel engines, the cylinder head gasket is often damaged;
- cracks appear in the cylinder block (usually - under the bed of indigenous liners);
- the power system of diesel engines running on domestic diesel fuel is often clogged;
- gearboxes are subject to oil leakage and rapid wear of synchronizers;
- axle shaft covers require constant attention, since if they are damaged, the constant velocity joints wear out very quickly.
The body is more resistant to corrosion than the Golf 1 models.
Despite these shortcomings, Golf II / Jetta II cars are among the most reliable and comfortable models in this class of cars.
Table 1. Main characteristics of engines
1) On vehicles manufactured for Austria, engines are marked according to engine numbers and EZA indices. On vehicles manufactured for Sweden and Switzerland: HM index, a Keihin carburetor and an exhaust gas recirculation system are installed. On cars manufactured since 6.91: ABN index.
2) Austrian variant 51 kW/70 hp
3) On cars produced for Sweden and Switzerland: HV index, a Keihin carburetor and an exhaust gas recirculation system are installed.
4) On vehicles manufactured for Sweden and Switzerland: index GZ.
5) When refueling with unleaded gasoline with an octane rating of 95, power is reduced.
