Cleaning the cooling circuit
|
Connect flushing equipment 87 91 824 to the cooling circuit in the opposite direction of flow.
Note
|
Important
|
|
Always use protective gloves. Incorrect connection can damage the gearbox, as the fluid filter includes a non-return valve preventing the fluid from circulating in the gearbox. Neither will the cooler be cleaned.
|
|
|
|
1.
|
Oil the sealing surface of the adapter plate with DEXRON II and fit a new fluid filter.
|
|
2.
|
Connect one of the hoses in the kit to the outlet on the bottom of the adapter plate (opposite to the fluid filter).
|
|
3.
|
Raise the car and remove the left-hand air shield.
|
|
4.
|
Detach the delivery hose from the lower transmission coupling and connect it to the coupling on the side of the adapter plate (inlet).
|
|
5.
|
Detach the return hose from the upper transmission coupling and connect the hose from the bottom of the adapter.
|
|
6.
|
Couple together the return hose from the cooler with the remaining hose in the kit and connect it to the lower coupling on the transmission.
|
|
7.
|
Fill the gearbox with fluid, start the engine and check the integrity of the connections.
|
|
8.
|
Apply the handbrake and depress the brake pedal.
|
|
9.
|
Move the selector lever to position D and let the cleaning process progress for 5 minutes.
|
|
10.
|
Detach the hose from the lower coupling on the transmission and separate the joint between the hose from the cooler and the hose from the cleaning kit.
|
|
11.
|
Detach the cleaning kit hose from the upper transmission coupling and connect the return hose from the cooler instead.
|
|
12.
|
Detach the delivery hose from the coupling on the side of the adapter (inlet) and connect it to the lower transmission coupling.
|
|
13.
|
Make sure the hoses are not resting on the subframe. Fit the air shield and lower the car.
|
|
14.

Check the engine oil and transmission fluid levels and top up as necessary.
