Fluid Specifications
|
Engine Oil Specification:
|
API SG/SH rated, SAE 5W-30, 5W-40, or 10W-40, depending on climate. Consult manual for precise VW specifications (e.g., VW 500 00). Oil capacity typically 4-5 liters.
|
Coolant Specification:
|
Ethylene Glycol based antifreeze, typically G11 specification (blue/green) or equivalent. 50/50 mix with distilled water. Capacity approximately 7-8 liters.
|
Brake Fluid Specification:
|
DOT 3 or DOT 4.
|
Transmission Fluid Manual:
|
Gear oil, e.g., GL-4 SAE 75W-90 or 80W-90. Capacity approx. 2.0-2.5 liters.
|
Transmission Fluid Automatic:
|
ATF DEXRON III (or manufacturer equivalent). Capacity approx. 3.5-4.0 liters for torque converter/transmission.
|
Known Issues
|
Known Issues Overview:
|
Common issues include aging rubber hoses and seals leading to vacuum leaks, fuel system component wear (injectors, fuel pumps), potential cooling system leaks (radiator, water pump), electrical gremlins in older wiring harnesses, and wear in suspension components like ball joints and control arm bushings. Timing belt failure can cause catastrophic engine damage. Early Quattro systems might require maintenance of the viscous coupling.
|
Common Maintenance Items:
|
Regular replacement of timing belt and tensioner, coolant system checks for leaks, maintaining clean fuel injectors, checking for vacuum leaks, and inspecting suspension wear.
