Caution: The coolant contains ethylene glycol and an anti-corrosion additive. Since the radiator, cylinder head, coolant pump housing and cylinder block (2.7L engine) 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. Place the vehicle on a level, horizontal surface and apply the parking brake.
2. Wait until the engine cools down.
3. Set the temperature control switch on the air conditioner and heater control panel to the maximum heating position ("MAX HOT").
4. Draining the fluid from the cooling system.
- a) Remove the radiator cap.
Caution: To avoid burns, do not remove the radiator cap or expansion tank cap when the engine is hot, as the liquid and steam are under pressure.
- b) Drain the coolant from the radiator into a suitable container by unscrewing the radiator drain plug located at the bottom.
- c) Remove the expansion tank and drain the coolant from it, then install the expansion tank back in place.
- d) If necessary, after draining the coolant, fill the radiator with clean distilled water or a special liquid to flush the cooling system.
- d) After the coolant has completely drained, tighten the radiator drain plug securely.
5. Filling with coolant.
- a) Slowly pour coolant into the radiator until it is completely full (to the base of the filler neck), and also fill the expansion tank without exceeding the "FULL" mark.
- Coolant: high-quality antifreeze for aluminum alloys (aluminum radiators) based on ethylene glycol.
- Concentration of antifreeze in the coolant: Recommended (for year-round use) 50%
- The range of acceptable concentrations is 30-60%
- Total filling volume:
- Engines 2.0 l/2.4 l - 7.3 l
- Engine 2.7L - 8.6L
Note: The total filling volume includes the volume in the expansion tank.
Attention:
- If the concentration of antifreeze is below 30%, the anti-corrosion properties of the coolant are significantly reduced.
- In addition, if the concentration is more than 60%, the crystallization temperature of the antifreeze increases (heat exchange efficiency decreases), adversely affecting the engine. Therefore, make sure that the antifreeze concentration level is within the specified range.
- Use a brand name ethylene glycol based coolant with an anti-corrosion additive and mix with demineralized or distilled water according to the manufacturer's instructions.
- Do not mix antifreezes of different brands.
- Do not use alcohol-based antifreeze.
- b) Tighten the radiator cap securely.
- c) 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. It should be warm when the thermostat is open.
7. After the thermostat opens, press the accelerator pedal two or three times, increasing the crankshaft speed to approximately 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: Use caution when removing the radiator cap or expansion tank cap on a hot engine.
9. Later, if the coolant level does not decrease, add coolant to the expansion tank up to the "FULL" mark.
