Installation
Installation is in the reverse order of removal.
CAUTION:
• Completely remove all moisture, oil and old gasket from the oil pan gasket mounting surface of tran-
saxle case and oil pan.
• Do not reuse O-rings, lip seals, oil pan gasket and oil pan bolts.
• Apply ATF to manual valve, O-rings, li p seals and sliding surfaces of the transaxle case.
NOTE:
• Set manual shaft in “N” position, then align manual plate (1) with
groove in manual valve (2).
• After installing control valve assembly to transaxle case, make sure that selector lever can be moved to all positions.
• After completing installation, check for A/T fluid leakage and A/T fluid level. Refer to AT-17, " Checking A/T Fluid " .

INSPECTION AFTER REMOVAL WARNING:
Use a protector to prevent a burn during the work.
Thermostat • Place a thread (A) so that it is caught in the valves of thermostat (1). Immerse fully in a container (B) filled with water. Heat while
stirring.
• The valve opening temperature is the temperature at which the valve opens and falls from the thread.
• Continue heating. Check the full-open valve lift amount.
• After checking the full-open valve lift amount, lower the water tem- perature and check the valve closing temperature.
• If out of the standard, replace thermostat.
INSPECTION AFTER INSTALLATION • Check that the reservoir tank cap is tightened.
• Check for leaks of engine coolant using suitable tools. Refer to CO-11, " Inspection " .
• Start and warm up the engine. Visually make sure that there is no leaks of engine coolant. PBIC3755E

- Check if valve seat is swollen to the extent that the edge of the plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.
• Pull negative-pressure valve to open it, and make sure that it is completely closed when released.
- Make sure that there is no dirt or damage on the valve seat of radi-
ator cap negative-pressure valve.
- Make sure that the valve operates properly in the opening and closing conditions.
• Check radiator cap relief pressure using Tool.
- When connecting the radiator cap to the tester, apply water or coolant to the cap seal surface.
- Replace the radiator cap if ther e is an abnormality in the negative-
pressure valve, or if the open-valve pr essure is outside of the standard values.
• Replace radiator cap if there it does not comply to specifications to the above three checks.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking Radiator INFOID:0000000004305239
Check radiator for mud or clogging. If necessary, clean radiator as follows.
• Be careful not to bend or damage radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator shroud and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward. • Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm 2
, 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out. PBIC2816E

CVT Fluid Cooler Cleaning INFOID:0000000004666864
Whenever a CVT is repaired, overhauled, or replaced, t he CVT fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can be tr apped or become deposit in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.

1. Identify the CVT inlet and outlet fluid cooler hoses.
2. Position an oil pan under the inlet and outlet cooler hoses. Fluid status Conceivable cause Required operation

Stall Test Procedure 1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the CVT fluid temperature is 50 to 80 °C (122 to 176 °F). Inspect the
amount of CVT fluid. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test. •It is good practice to mark the point of specified engine
rpm on indicator.
