Coolant, draining and filling: Refilling
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Volkswagen Jetta, 2002 Volkswagen GTI, 2001 Volkswagen Jetta, 2001 Volkswagen GTI, and 2000 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- To satisfy TL VW 774 D , only G 12 may be used as a coolant additive. Color coding: red.
- Only mix G 12 with clean water. Never mix G 12 with any other coolant additives!
- If the liquid in the coolant expansion tank is brown, this means that G 12 was mixed with another coolant and the coolant has to be changed.
- G 12 and additives which are labeled satisfies TL VW 774 D prevent damage from freezing and corrosion and prevent lime deposits. They also raise the boiling point. For these reasons, the cooling system must be filled with antifreeze and anti-corrosion agents throughout the year.
- The coolants higher boiling point will contribute to operational reliability under higher engine loads, especially in tropical climates.
- The antifreeze protection must go down to 25 ° C (in Arctic climates down to 35 ° C).
- The concentration of the coolant may not be reduced by topping up during the warm seasons or in warm countries. The proportion of additive must be at least 40%.
- If the climate requires stronger antifreeze protection, the portion of G 12 can be increased, but never above 60% (antifreeze protection down to about 40 ° C), otherwise the antifreeze protection will begin to decrease again and the cooling effect will be reduced.
- Do not reuse the same coolant if the radiator, heat exchanger, cylinder head or cylinder head gasket have been replaced.
Recommended mixing ratios:
| Protection to | Antifreeze | G 12 * See note |
Clean Water * See note* See note |
| -25 ° C -35 ° C | 40% 50% | 3.6 liters 4.5 liters | 5.4 liters 4.5 liters |
* The amount of coolant may vary depending on the vehicle accessories.
* Use only clean water for mixing.
- Tighten drain plug into radiator return.
- Push coolant hose onto oil cooler connection and pull it tight.
- Fill with coolant up to upper mark on cross-hatched area on coolant expansion tank.
- Close coolant expansion tank.
- Expose heater controls and turn off air conditioning if necessary.
- Start engine and run at approximately 2000 rpm for about 3 minutes.
- Keep engine running until fan starts.
- Check coolant level and fill as necessary.
The coolant level must be within the cross-hatched region when the engine is running warm. It must be above the lower mark if the engine is cold.
