Note. Pour GLACEOL RX antifreeze into the cooling system (type D).
You will need: coolant, a clean rag, a container for draining coolant with a capacity of at least 10 liters, pliers.
Attention! Change the coolant only when the engine is cold. The coolant is toxic, so be careful when handling it. When starting the engine, the expansion tank cap must be closed. Screw the tank cap tightly. The cooling system is pressurized when the engine is running, so coolant may leak from under the loose cap.
1. Install the car on a flat horizontal platform.
2. Turn away a stopper of a broad tank.
3. Remove the air release valve plug.
4. Remove the crankcase protection (see «Removal and installation of mudguards and engine crankcase protection»).
5. Squeezing the clamp of the lower radiator hose with pliers, slide the clamp along the hose...
6.... remove the hose from the radiator pipe and drain the liquid into a container.
Warning! Antifreeze is deadly poisonous to all living things. in order not to pollute the environment, drain it through a funnel (for example, made from a plastic soda bottle).
7. After draining the coolant, tighten the air release valve plug.
8. Fill the expansion tank with water to flush the system.
9. Apply compressed air to the expansion tank to purge the cooling system to remove as much water as possible from it.
10. Connect the lower radiator hose.
11. Install the crankcase protection.
12. Fill with coolant (air release valve plug must be removed).
13. After the air has stopped coming out of the valve and liquid has appeared from it, wrap the valve plug and the plug of the expansion tank.
14. Start the engine, bring the crankshaft speed to 2500 min-1 and let it run until the fan turns on. After that, turn off the engine, check the coolant level and, if necessary, add it to the expansion tank to the mark «MAX».
Note. When the engine is running, watch the coolant temperature on the gauge. If the indicator scale is completely shaded, and the radiator fan does not turn on, turn on the heater and check how much air passes through it. If the heater supplies heated air, the fan is most likely defective, and if it supplies cold air, then an air lock has formed in the engine cooling system. To remove it, turn off the engine, let it cool and unscrew the plug of the expansion tank. Start the engine, let it run for 3-5 minutes and tighten the reservoir cap.
Note. For better filling of the system without air pockets, periodically squeeze the radiator hoses by hand.
After a few days of operation of the car after replacing the coolant, check its level. Top up if necessary.
If after a very short time the color of the fresh liquid turns brown, then you have poured a fake into which the manufacturer «forgot» add corrosion inhibitors. In addition, one of the signs of a fake is a sharp complete discoloration of the liquid. The dye of high-quality coolant is very resistant and only darkens over time. The liquid, tinted with linen blue, is discolored. Such «antifreeze» needs to be replaced quickly.
