939010369 - 0010T20 ENGINE COOLANT - CHANGE

Procedure for draining the circuit.- With the engine cold, undo the engine coolant reservoir cap.
Do not remove the tank cap when the engine is warm as there is a risk of scalding.
    Op. 7055B54 UNDER ENGINE PROTECTION/GUARD - 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. Open the bleed screw on the water pump rigid inlet pipe.
1. Slowly introduce the recommended fluid into the circuit via the filler on the engine coolant supply reservoir keeping the level above the MAX reference until fluid comes out of the bleed, then close the bleed screw.

- Complete the introduction of the engine coolant until the MAX reference is reached on the reservoir.- Start the engine keeping it idling for about 2 minutes and, at the same time, top up, if necessary to the MAX level.- Fit the engine coolant reservoir cap and tighten.- Then carry out gradual, periodic acelerations (about every 30 secs.) until the engine speed is 3000 rpm. Repeat this operation until the fan cuts in for about three 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 in the tank 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.- After the above operations and with the engine cold, check the fluid level in the engine coolant reservoir and top up to the MAX notch on the reservoir if necessary.- 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.    Op. 7055B54 UNDER ENGINE PROTECTION/GUARD - R.R.
