Contents: Filling the cooling system 🠛 Removal air 🠛
- In the cooling system, there is no radiator tap heating system of the passenger compartment. The circulation of the coolant is constantly carried out through the radiators of the heating system, which thus participate in the cooling of the engine.
Filling the cooling system
- Connect the lower hose to the radiator.
- Screw the coolant drain plug into the cylinder block
- Unscrew the air bleed plugs on the radiator, the supply hoses to the heating system radiators, at the thermostat outlet and on the coolant housing (Fig. 3.77).
Fig. 3.77. Location of the air bleed plug
- Fill the cooling system with coolant through the filler hole of the expansion tank.
- Starting from the bottom, close the air bleed plugs as soon as coolant flows out of them in a continuous stream.
- Fill the expansion tank to the mark "Maxi"
- Start the engine and let it run at 2500 rpm.
- After 4 minutes, add coolant to the required level
- Close the expansion tank cap.
Removal air
- Run the engine for 20 minutes at 2500 rpm until the radiator fan comes on (time required for automatic air removal).
- Make sure that the fluid level in the expansion tank is in the area of the "Maxi" mark.
- Do not open the air bleed plugs while the engine is running.
- Tighten the expansion tank cap on a warm engine.
