Attention! If the coolant is drained as part of a vehicle repair, it must be collected for reuse. If the water pump, radiator or cylinder head is being replaced, the coolant must be replaced with a new one. Only fill the system with coolants approved by RENAULT, e.g. CLACEOL RX (type D).
Attention! The coolant is poisonous. It cannot be poured in random places. To do this, you need to find out where the nearest collection point for special funds is located or to hand over the coolant at a disposal point.
Coolant drain
1. Remove the cap from the filler neck of the expansion tank.
2. Check the condition of the cover gasket.
Note: When the engine is hot, before removing the expansion tank filler cap, place a thick cloth on it to prevent burns from hot coolant or steam. Remove the cover only when the coolant temperature is below +90°C.
3. Remove if there is a mudguard (protection) engine.
4. Place a clean container under the radiator and engine to collect the coolant.
5. Loosen the clamp securing the lower coolant circulation hose to the radiator and remove the hose (see illustration). If necessary, cut the pressed clamp with side cutters and install a clamp instead of it when connecting the hose.
2.5 Loosen the clamp securing the lower coolant circulation hose to the radiator and remove the hose
6 Drain, if necessary, for example, when repairing an engine, the coolant from the cylinder block by unscrewing the plug from the drain hole on the block (see illustration). For vehicles with a 1.4-/1.6-litre petrol engine (K7J/K7M) The drain plug is located on the back of the cylinder block next to the alternator.
2.6 Drain, if necessary, for example, when repairing an engine, the coolant from the cylinder block by unscrewing the plug from the drain hole on the block. Vehicles with a 1.4-/1.6-liter petrol engine (K7J/K7M)
2.6a For vehicles with a 2.0 liter petrol engine and a 1.9 liter diesel engine, the drain plug is located on the rear side of the cylinder block above the intermediate shaft
Coolant from the system of vehicles with a 1.4-/1.6-liter petrol engine (K4J/K4M) drains completely after disconnecting the lower radiator hose.
7. Drain the coolant.
8. Screw the drain plug back into place, replacing its old O-ring with a new one. Plug tightening torque 10 Nm.
9. Connect the lower hose to the radiator and secure it with a clamp.
10. Install, if available, the engine mudguard.
Removal of air from the cooling system
11. Remove the vent plug from the top of the radiator. Depending on the type of radiator, the plug can be either on the left or on the right side of the radiator (see illustration).
2.11 Unscrew the vent plug at the top of the radiator
12. Unscrew the plug of additional ventilation of the system, if any. Vent plugs on all engines except 2.0 liter petrol engine (150 hp) and a 1.4-/1.6-liter petrol engine (K4J/K4M), located on the heater radiator pipe (see arrow in illustration). For a 2.0-liter gasoline engine and a 1.9-liter diesel engine, the vent plug is located next to the partition of the engine compartment. The 113 hp engine has and diesel engine, the vent plug is located on the top side of the thermostat housing (see arrow in illustration 2.12a).
2.12 Vent plugs on all engines except 2.0 liter petrol engine (150 hp) and a 1.4-/1.6-liter petrol engine (K4J/K4M), located on the heater radiator pipe (see arrow). Ventilation plug for a gasoline engine with a volume of 1.4-71.6 liters (K4J/K4M) on the thermostat housing on the flywheel side (see arrow in illustration 2.12b).
2.12a For an engine with a power of 113 hp. and diesel engine, the vent plug is located on the top side of the thermostat housing (see arrow). The illustration shows a diesel engine
2.126 Vent plug on a 1.4-/1.6-liter petrol engine (K4J/K4M) on the thermostat housing on the flywheel side (see arrow)
13. Fill in system through a mouth of a broad tank with a cooling liquid. As soon as the liquid begins to flow out through the vent in a uniform stream, screw in the plugs and add liquid to the mark «MAX» on the expansion tank.
14. Start the engine and let it run for about four minutes at 2500 rpm (150 hp engine - 1500 rpm). Keep an eye on the coolant level and top up if necessary.
15. Screw a cover on a jellied mouth of a broad tank.
16. Start the engine and let it run for approximately 20 minutes at 2500 rpm (150 hp engine - 1500 rpm) until the radiator fan turns on. This is necessary to remove air from the system.
17. Tighten the cap on the filler neck of the expansion tank by placing a rag on it.
18. Check the coolant level in the reservoir. If necessary, after the engine has cooled down, replenish its volume to the level «MAX».
Attention! Do not remove the ventilation plugs while the engine is running. If air has not been completely removed from the system, then it can heat up to a vapor state.
19 Check the tightness of the cooling system, especially at the hose connections, vent plugs and water pump.
