Brake Fluid Replacement
Warning! Old brake fluid is darker in color than new.
The operation for changing the brake fluid is similar to the operation for bleeding the brakes, except that the brake fluid reservoir must be emptied of the old brake fluid.
1. Open the first bleed valve and pump the brake pedal until the old brake fluid comes out of the brake master cylinder. Add brake fluid to the max mark in the reservoir and pump again until new brake fluid appears in the bleeder, then screw the bleeder. Similarly pump over brake contours of other wheels.
2. When bleeding, do not allow the brake fluid level in the reservoir to drop below the min mark. Otherwise, air may enter the hydraulic brake system.
3. Check the tightness of the bleeder fittings, install dust caps on them and wipe off traces of brake fluid.
4. Check the operation of the brake system when the vehicle is moving at low speed.
Replacing the battery in the remote control
Warning! The battery in the remote control must be replaced within 3 minutes, otherwise the remote control system will need to be reprogrammed.
1. Using a screwdriver, remove the battery cover from the remote control box.
2. Mark the polarity of the battery and remove it from the remote control.
3. Install a new battery and close the battery cover.
Coolant replacement
Warning! The coolant is changed on a cold engine. Avoid getting coolant on painted body surfaces and clothing. Otherwise, wash the area where the coolant has entered with plenty of water.
Coolant drain
1. Remove the cap from the expansion tank.
2. Remove the mudguard under the engine compartment and install the container under the radiator on the left side.
3. Loosen the clamp and remove the hose from the radiator base and drain the coolant into a container.
4. After draining the coolant, install the hose on the radiator and secure it with a clamp.
Flushing the cooling system
5. The coolant must be changed periodically, and the cooling system must be flushed, as rust and dirt form in the channels of the system. The radiator must be flushed regardless of the engine.
Flushing the radiator
6. Disconnect the hoses from the radiator.
7. Insert the hose into the inlet of the upper radiator tank, turn on the water and flush the radiator until clean water appears from the lower radiator tank.
8. If it is not possible to flush the radiator with clean water, then use a detergent.
Engine flush
9. Remove the thermostat and disconnect the hoses from the radiator.
10. Install the thermostat and connect the cooling system hoses.
Filling the cooling system
11. Before filling the cooling system, check that all hoses inside are in good condition. Note that the antifreeze mixture must be used all year round to prevent corrosion.
12. Remove the cap from the expansion tank.
13. On 1.6L SOCH engines, remove the coolant temperature sensor from the top of the thermostat housing. This is necessary to remove air from the cooling system. On other engines, air is removed from the cooling system automatically when the engine warms up.
14. Slowly fill in the coolant until the level reaches the max mark on the expansion tank. On 1.6L SOCH engines, install the temperature sensor after clear, bubble-free coolant emerges from the sensor hole.
15. Install the expansion tank cap.
16. Start the engine and warm it up to operating temperature.
17. Stop the engine and cool it down, then check the coolant level.
Antifreeze
Antifreeze is a mixture of distilled water and ethylene glycol concentrate. Antifreeze protects the cooling system from corrosion and increases the boiling point of the coolant. The amount of ethylene glycol in antifreeze depends on the weather conditions of the car and ranges from 40 to 70%.
