198000018 - 0010T20 ENGINE COOLANT - CHANGE

Procedure for draining the circuit.    Op. 1016A10 SOUND-PROOFING COVER - R.R - With the engine cold, undo the engine coolant supply reservoir cap.
Do not remove the tank cap when the engine is warm as there is a risk of scalding.
    Op. 7055B65 ENGINE COMPARTMENT DUST COVER IN LEFT FRONT WHEEL ARCH - R.R. 1. Open the radiator coolant drainage tap.
Collect the coolant in a suitable container.
Procedure for refilling the circuit.- Close the tap on the radiator used for draining the circuit.1. Loosen the bleed valve on the top right part of the radiator.
1. Remove the bleed screw on the water pump rigid inlet pipe.2. Remove the bleed screw on the rigid water supply pipe to the engine oil heat exchanger.
1. Loosen the bleed screw on the heater return pipe.
- Introduce the recommended fluid via the filler and close the bleed screws on the radiator, on the water pump return pipe, on the rigid water supply pipe to the engine oil heat exchanger and on the return pipe from the heater as soon as the fluid comes out.

1. Complete the introduction of fluid until the MAX level is reached and then close the filler cap.
- Start up the engine and let it idle for about 2 minutes.- At the same time top up the fluid, if necessary, to the MAX reference.- Tighten the plug on the reservoir fitting.- Start the engine and remove the air from the circuit by pumping the accelerator regularly and gradually (every 30 secs) up to a speed of around 3000 rpm. This operation should be carried out until the thermostat opens and the fan switches on and off at least 3 times. During this operation keep the climate control system switched off to prevent the fan from coming on for reasons unconnected to the heating of the coolant. If there is a noticeable drop in the level (below the MIN reference) during this stage, let the engine idle and open the cap very carefully, topping up the fluid to the MAX level, then close the cap fully and remove all the air from the system.- Stop the engine and wait until the circuit has cooled down sufficiently.- Check whether the fluid in the tank needs topping up to the MAX level.- At the end of the above operations, make sure that the amount of fluid introduced into the system is at least equal to the amount collected during the draining stage.
