PRECAUTIONS
Revision: 2007 April2007 M35/M45
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-47, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.

If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.

As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.

Within five minutes of liquid gasket application, install the mat-
ing component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten after mounting bolts and nuts the installation.

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

RADIATOR
Revision: 2007 April2007 M35/M45

Minimize the lift of A/C condenser to prevent load from being applied to A/C piping.
e. After removing the radiator, place the A/C condenser on the radiator core support to prevent load from
being applied to piping. And then, temporarily secure them using a rope to prevent them from being
dropped.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-11, "
LEAK CHECK" .

Start and warm up the engine. Visually make sure that there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapNBS004QU

Check valve seat of radiator cap.
–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
close completely when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) (A) and the radiator cap tester adapter
(commercial service tool) (B), apply engine coolant to the cap
seal surface.

Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorNBS004QV
Check radiator for mud or clogging. If necessary, clean radiator as follows.

WATER PUMP
Revision: 2007 April2007 M35/M45
b. Screw M8 bolts [pitch: 1.25 mm (0.049 in) length: approx. 50
mm (1.97 in)] into water pumps upper and lower mounting bolt
holes until they reach timing chain case. Then, alternately
tighten each bolt for a half turn, and pull out water pump.
CAUTION:

Pull straight out while preventing vane from contacting
socket in installation area.

Remove water pump without causing sprocket to contact
timing chain.
c. Remove M8 bolts and O-rings from water pump.
CAUTION:
Do not disassemble water pump.
INSPECTION AFTER REMOVAL

Check for badly rusted or corroded water pump body assembly.

Check for rough operation due to excessive end play.

If anything is found, replace water pump.
INSTALLATION
1. Install new O-rings to water pump.

Apply engine oil and engine coolant to O-rings as shown in
the figure.

Locate O-ring with white paint mark to engine front side.
2. Install water pump.
CAUTION:
Do not allow cylinder block to nip O-rings when installing
water pump.

Make sure timing chain and water pump sprocket are
engaged.

Insert water pump by tightening mounting bolts alternately
and evenly.
3. Install timing chain tensioner (primary) as follows:

4. Drain engine coolant from radiator drain plug at the bottom of radiator, and from water drain plug at the
front of cylinder block. Refer to CO-11, "
Changing Engine Coolant" and CO-24, "WATER PUMP" .
CAUTION:

Perform this step when the engine is cold.

Do not spill engine coolant on drive belts.
5. Disconnect radiator hose (lower) and oil cooler water hose from water inlet and thermostat assembly.
6. Remove water inlet and thermostat assembly.
CAUTION:
Do not disassemble water inlet and thermostat assembly.
Replace them as a unit, if necessary.

INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using radiator cap tester adapter (commercial service tool) and radiator
cap tester (commercial service tool). Refer to CO-40, "
LEAK CHECK" .

Start and warm up engine. Visually Check if there is no leaks of engine coolant and A/T fluid.
Checking Radiator CapNBS004RI

Check valve seat of radiator cap.
–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
close completely when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester adapter
(commercial service tool) (B) and the radiator cap tester (com-
mercial service tool) (A), apply engine coolant to the cap seal
surface.

Replace radiator cap if there is an unusualness.
CAUTION:
When installing a radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorNBS004RJ
Check radiator for mud or clogging. If necessary, clean radiator as follows:

Be careful not to bend or damage the radiator fins.

When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape the harness and electrical 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.
