2. Remove the soundproof cover at the bottom of the motor. Prepare a container to collect the liquid. Never drain coolant directly onto the ground.
3. Remove the spring clip 1 of the coolant temperature sensor 2. After that, pull the sensor out of the pipe and drain the water.
In order to drain the coolant, you need to pull the coolant temperature sensor out of the pipe
4. Also remove the hose on the oil cooler (arrow) and drain the rest of the liquid.
The rest of the coolant can be drained only if the hose is removed from the oil cooler
5. Dispose of the collected fluid in an environmentally friendly manner.
6. Before filling in the coolant, insert the temperature sensor 2 with a new sealing ring into the pipe and secure it with a spring clip /. Also, connect the hose to the oil cooler.
7. After that, fill in the coolant until it comes out of the vent hole in the pipeline. After screwing in the air valve, continue to add fluid until it comes out of the vent hole in the hose that goes to the heat exchanger of the heating system. Then slide the hose onto the nozzle and secure it with a spring band clamp.
Get to the air valve (arrow) in the upper pipe in a six-cylinder engine is possible only after removing the engine front cover
8 Close the expansion tank.
Air vent (arrow) on the hose that goes to the heat exchanger of the heating system can only be seen if the hose is pulled back so that the hole is no longer closed by the connecting pipe. Before that, you still need to remove the cover of the battery section. The cover can be removed by pulling it forward after removing the rubber seals.
9. Start the engine, the engine should run for approximately 3 minutes at 2000 rpm. The engine should then idle until the bottom hose at the radiator is hot.
10. Check the coolant level. When the engine is warmed up to operating temperature, the fluid should reach the maximum mark; when the engine is cold, the fluid level should be between the minimum and maximum marks.
