2. Pull the negative-pressure valve to open it and check that it
closes completely when released.
• Check that there is no dirt or damage on the valve seat of the
radiator cap negative-pressure valve.
• Check that there are no abnormalities in the opening and clos- ing conditions of the negative-pressure valve.
3. Check radiator cap relief pressure using suitable tool and Tool. • When connecting the radiator cap to the tester, apply water orcoolant to the cap seal surface.
• Replace the radiator cap if there is an abnormality in the nega-
tive-pressure valve, or if the open-valve pressure is outside of
the standard values.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.
CAUTION:
• Be careful not to bend or damage the radiator fins.
• When radiator is cleaned on-vehicle, remove surr ounding parts in order to access the radiator core.
Tape the harness and electrical connectors to prevent water from entering.
1. Spray water to the back side of the radiator co re using a side to side motion from the top down.
2. Stop spraying when debris no longer flows from radiator core.
3. Blow air into the back side of radiator core using a side to side motion from the top down.
• Use compressed air lower than 490 kPa (5 kg/cm
2, 71 psi) and keep distance more than 30 cm (11.8 in).
4. Continue to blow air until no water sprays out.
5. Check for coolant leaks. Repair as necessary.
Changing Engine CoolantINFOID:0000000009460391
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
DRAINING ENGINE COOLANT
1. Remove the engine under cover. Refer to EXT-17, "Removal and Installation".
2. Open the radiator drain plug at the bottom of the radi ator and remove the radiator filler cap. This is the
only step required when partially draining the cooling system (radiator only).
CAUTION:
• Do not allow the coolant to contact the drive belt.
• Perform this step when engine is cold.
3. Follow this step for heater core removal/replac ement only. Disconnect the upper heater hose at the
engine side and apply moderate air pressure [103.46 kPa (1.055 kg/cm
2, 15 psi) maximum air pressure]
into the hose for 30 seconds to blow t he excess coolant out of the heater core.
4. When draining all of the coolant in the system, re move the reservoir tank and drain the coolant, then clean
the reservoir tank before installation.

5. When draining all of the coolant in the system for engine removal or repair, open the drain plugs (A and B) on the cylinder
block.

6. Check the drained coolant for contaminants such as rust, corrosion or discoloration. If the coolant is contaminated, flush the engine cooling system.
REFILLING ENGINE COOLANT
1. Install the radiator drain plug. Install the reservoir tank and cylin-
der block drain plug, if removed for a total system drain or for
engine removal or repair.
• The radiator must be completely empty of coolant and
water.
• Apply sealant to the threads of the cylinder block drain
plug. Use Genuine High Pe rformance Thread Sealant or
equivalent. Refer to GI-21, "Recommended Chemical
Products and Sealants".
: Front
CAUTION:
Do not reuse copper sealing washers.
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.

2. Remove the core support cover clips (A), then remove the core
support cover (1).
3. Remove air cleaner assembly and front air duct. Refer to EM-84, "Removal and Installation"
.
4. Remove the engine room cover. Refer to EM-28, "Removal and Installation"
.
5. Remove the upper radiator hose, heater pipe, electric throttle control actuator inlet hose, water hose, and
water temperature sensor.
6. Remove the water outlet, O-ring and gasket. CAUTION:
• Do not reuse O-ring.
• Do not reuse gasket.
• Do not reuse water outlet.
INSTALLATION
Installation is in the reverse order of removal.
• Install the engine coolant temperature sensor. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-21, "Recommended Chemical Products
and Sealants".
• Install the heater pipe, first apply a mild soap to t he O-ring and quickly insert the heater pipe into the hous-
ing.
CAUTION:
• Do not reuse O-ring.
• Do not reuse gasket.
• Do not reuse water outlet.
• After installation, refill coolant and check for leaks. Refer to CO-12, "Changing Engine Coolant"
and CO-11,
"System Inspection".
CAUTION:
Do not spill coolant in engi ne compartment. Use a shop cloth to absorb coolant.
