Flushing the radiator or cooling system of a Renault Clio 1.9D is an important maintenance task that helps to remove dirt, debris, and old coolant from the system. Keeping the cooling system clean and properly maintained can help to prevent overheating, corrosion, and other problems.
To flush the radiator or cooling system of a Renault Clio 1.9D, you will need the following materials and tools:
* New coolant (Renault recommends Glaceol RX Type D coolant)
* Distilled water
* A funnel
* A drain pan
* A hose clamp pliers
* A screwdriver
* A bucket
* Safety glasses
* Gloves
Step 1: Prepare the vehicle
Start the engine and let it run for several minutes until it reaches operating temperature. This will help to loosen any dirt or debris in the radiator or cooling system.
Step 2: Drain the radiator
Place the drain pan under the radiator draincock, which is located at the bottom of the radiator on the left side. Use the screwdriver to loosen the draincock and allow the coolant to drain into the pan.
Step 3: Drain the engine block
After all of the coolant has drained from the radiator, close the draincock and move the drain pan under the engine block. There is another draincock on the engine block, which is located near the water pump. Use the screwdriver to loosen the engine block draincock and allow the coolant to drain into the pan.
Step 4: Flush the radiator
Once all of the coolant has drained from the radiator and the engine block, use the garden hose to flush the radiator with clean water. Run the water through the radiator for several minutes until the water runs clear.
Step 5: Fill the radiator
Once the radiator has been flushed, use the funnel to fill the radiator with new coolant. Add enough coolant to bring the coolant level to the "FULL" mark on the coolant reservoir.
Step 6: Start the engine
Start the engine and let it run for several minutes until the thermostat opens and the coolant begins to circulate through the cooling system. Check for any leaks around the radiator, hoses, and draincocks.
Step 7: Add coolant to the reservoir
If the coolant level in the reservoir drops below the "FULL" mark, add more coolant to bring the level back up.
That's it! You have successfully flushed the radiator or cooling system of your Renault Clio 1.9D.
