	To radiator. Refer to Exploded View.
	: Always replace after every disassembly.

CAUTION:

Metal debris and friction material may become trapped in the radiator, cooling hoses, bypass valve or external CVT fluid cooler (if equipped). This debris can contaminate a newly serviced transmission, control valve or torque converter. In severe cases this debris can block or restrict flow and may cause damage to a newly serviced CVT.

Always perform a CVT Fluid Cooler Flush after any one of the following:

• CVT (transaxle) assembly overhaul, internal repair or replacement

• Control valve replacement

• Torque converter replacement

CVT FLUID COOLER CLEANING PROCEDURE

CAUTION:

• Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner.

• Spray Cooler Cleaner only in areas with adequate ventilation.

• Avoid contact with eyes and skin.

• Do not breathe vapors or mist from spray.

Remove front under cover. Refer to Removal and Installation.

Position an oil drain pan under the CVT fluid cooler.

Position an oil drain pan under the CVT oil warmer.

Disconnect the CVT fluid cooler hose A and CVT fluid cooler hose B from the CVT oil warmer. Refer to Exploded View.

CAUTION:

Do not reuse hose clamps.

NOTE:

• If rubber material from cooler hose remains on the steel tube or fitting, clean steel tube and replace rubber hose.

• The hoses removed from the CVT fluid warmer will be flushed first in one direction and then the other.

Allow any transmission fluid that remains in the CVT fluid cooler hoses to drain into the oil drain pan.

Flush CVT fluid cooler and hoses using the following steps:Attach a suitable hose (A) to the CVT fluid cooler hose (1).

CAUTION:

• Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner.

• Spray Cooler Cleaner only in areas with adequate ventilation.

• Avoid contact with eyes and skin.

• Do not breathe vapors or mist from spray.

NOTE:

Always check with the Parts Department for latest parts information.

Attach a suitable hose over the end of the CVT fluid cooler hose (2) that was used as the flush inlet.

Blow compressed air through CVT fluid cooler hose (2) for 10 seconds to force remaining fluid out of CVT fluid cooler hose (1).

Repeat steps 6-8 one additional time, then proceed to step 10.

Reverse flush the CVT fluid cooler. Install Transmission Cooler Cleaner to CVT fluid cooler hose (1), then repeat steps 6-8 twice.

Install CVT fluid cooler hose A and CVT fluid cooler hose B to the CVT oil warmer. Refer to Exploded View.

CAUTION:

Do not reuse hose clamps.

Fill the transaxle assembly with CVT fluid. Refer to Replacement.
