Caution: The coolant contains ethylene glycol and an anti-corrosion additive. Since the radiator, cylinder head, water pump housing and cylinder block (engine 2.7 l) are cast from aluminum alloy, periodic replacement of the coolant is necessary to prevent corrosion of these parts. In addition, it is not allowed to replace the coolant with clean water, even in summer.
1. Park the vehicle on a level surface and apply the parking brake.
2. Wait for the engine to cool down.
3. Set the temperature control switch on the air conditioning and heater control panel to the maximum heat position ("MAX NOTE").
4. Draining liquid from the cooling system.
- A) Remove the radiator cap.
Caution: To avoid burns, do not remove the radiator cap or expansion tank cap while the engine is hot, as fluid and vapor are under pressure.
- b) Drain the coolant from the radiator into a suitable container by removing the drain plug located at the bottom of the radiator.
- V) Remove the expansion tank and drain the coolant from it, then reinstall the expansion tank.
- G) If necessary, after draining the coolant, fill the radiator with clean distilled water or special liquid to flush the cooling system.
- d) After the coolant is completely drained, securely tighten the radiator drain plug.
5. Filling the coolant.
- A) Slowly pour coolant into the radiator until it is full (to the base of the filler neck), and also fill the expansion tank without exceeding the mark "FULL".
- Coolant: high quality antifreeze for aluminum alloys (aluminum radiators) based on ethylene glycol.
- Concentration of antifreeze in the coolant: Recommended (for year-round operation) 50%
- The range of permissible concentrations is 30-60%
- Total filling volume:
- Engines 2.0L/2.4L - 7.3L
- Engine 2.7 l - 8.6 l
Note: The total filling volume includes the volume in the expansion tank.
Attention:
- If the antifreeze concentration is below 30%, then the anti-corrosion properties of the coolant are significantly reduced.
- In addition, if the concentration is more than 60%, then the crystallization temperature of antifreeze rises (heat exchange efficiency decreases), adversely affecting the engine. Therefore, make sure that the antifreeze concentration level is within the specified range.
- Use a proprietary ethylene glycol based anti-corrosion coolant and mix with demineralized or distilled water according to the manufacturer's instructions.
- Do not mix different brands of antifreeze.
- Do not use alcohol antifreeze.
- b) Screw on the radiator cap securely.
- V) Install the expansion tank cap.
6. Start the engine and warm it up until the thermostat opens.
Note: To check the condition of the leaking coolant, touch the radiator hose with your hand. When the thermostat is open, it should be warm.
7. After opening the thermostat, press the accelerator pedal two or three times, increasing the engine speed to about 3000 rpm, and then turn off the engine.
8. After stopping the engine, let it cool down, then remove the radiator cap and check the coolant level. If the level is low, add coolant to the edges of the radiator filler neck.
Note: Be careful when removing the radiator cap or expansion tank cap when the engine is warm.
9. Later, if the coolant level does not drop, then add coolant to the expansion tank to the mark "FULL".
