Engine Options:
Covered various gasoline and diesel engines, including: 1.3L, 1.6L (8V and 16V), 1.8L (8V and 16V), and 1.6L Diesel. Specific engines like the 1.8L GTI (DX, PL, KR codes) were performance highlights.
Power Output:
Varies by engine: 55-112 hp for gasoline, 50-70 hp for diesel. GTI models offered higher performance outputs.
System Type:
Carburetor (e.g., Pierburg 2E2, Solex) for base models, Bosch CIS-Jetronic and later Digifant fuel injection for higher performance and later models.
Examples:
Common gasoline engine codes: GU (1.8L), RP (1.8L), PF (1.8L 16V), PL (1.8L 16V GTI), KR (1.8L 16V GTI). Diesel: JK (1.6L D), RA (1.6L TD).
Oil Change:
Typically every 5,000 to 7,500 miles (8,000 to 12,000 km) or 6-12 months, depending on driving conditions and oil type.
Timing Belt:
Critical: Replacement recommended every 60,000 miles (100,000 km) or 5 years to prevent catastrophic engine damage on interference engines.
Engine Oil:
Refer to manual for specific viscosity (e.g., 10W-40, 15W-50 depending on climate and engine) and API service classification. VW 500.00 or similar for gasoline.
Coolant:
Ethylene glycol-based antifreeze mixed with distilled water. Manual specifies correct mixture ratio and type (e.g., G11). Capacity approx. 6-7 liters.
Brake Fluid:
DOT 3 or DOT 4 brake fluid. Capacity approx. 0.75 - 1 liter.
Transmission Fluid Manual:
API GL-4 gear oil, SAE 75W-90 or 80W-90. Capacity approx. 2.0-2.5 liters.
Transmission Fluid Automatic:
ATF (Automatic Transmission Fluid) like Dexron II or equivalent. Manual specifies exact type. Capacity approx. 3-4 liters for drain and refill.
Power Steering Fluid:
If equipped with power steering, it typically uses ATF or a dedicated power steering fluid. Manual will specify.
Common Problems:
Rust (wheel wells, rocker panels, around windows), cooling system leaks (hoses, radiator, water pump), fuel injection issues (early systems), electrical gremlins, worn suspension components, clutch wear, distributor o-ring leaks.
Gti Specific:
More prone to head gasket issues if overheated, more complex fuel injection tuning.
Oil Filter Example:
Example: Mann-Filter W 920/1 or equivalent Bosch 0 451 103 252. Specific part number needed based on engine.
Air Filter Example:
Example: Mann-Filter C 24 132/1 or equivalent Bosch 1 457 433 028. Specific part number needed based on engine.
Spark Plug Example:

Heritage:
Volkswagen has a long history of producing reliable and practical small cars, dating back to the Beetle. The Golf/Jetta (A2) continued this tradition.
Evolution:
The MK2 Golf/Jetta (A2) was introduced in 1983 (as a 1984 model) and represented a significant redesign from the MK1, featuring larger dimensions, improved aerodynamics, and updated styling. It was produced until 1991/1992 with various facelifts.
Key Changes Mk1 To Mk2:
Larger, more aerodynamic body; improved suspension geometry for better ride and handling; updated interior ergonomics; wider engine options, including 16-valve performance variants.
Locations:
Primarily produced in Wolfsburg, Germany, and also manufactured in various other plants worldwide, including North America.
Facelifts:
The MK2 Golf/Jetta received a significant facelift around 1987/1988, which included updated dashboard styling, new exterior trim options, and often revised engine management systems.
