Radiator Cap Test
1. Remove the radiator cap {A), wet its seal with
engine coolant, then install it on the pressure tester(B) (commercially available).
Apply a pressure of 93 '123 kPa {0.95 1.25
kgf/cm', l4 18 psi).
Check for a drop in pressure.
lf the pressure drops, replace the cap.

4.
Radiator Test
Wait untilthe engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top of the filler neck.
Attach the pressure tester (A) (commercially
available) to the radiator.

4.
Apply a pressure ot 93 '123 kPa (0.95 1 .25
kgf/cm', '14 18 psi).
Inspect for engine coolant leaks and a drop in
pressu re.
Remove the tester, and reinstall the radiator cap.

Cooling System
1 . Look at the coolant level in the reserve tank. Make
sure it is between the MAX mark (A) and MIN mark(B),
Goolant Check
lf the coolant level in the reserve tank is at or below
the MIN mark, add coolant to bring it up to the l\4AX
mark, and inspect the cooling system for leaks.

Start the engine. Set the heater temperature control
dial to maximum heat. then turn off the ignition
switch. Make sure the engine and radiator are cool
to the touch.
Remove the radiator cap.
Remove the splash shield (see step 23 on page 5-5).
Loosen the drain plug (A), and drain the coolant.
Remove the reserve tank drain cap (A), and drain
the coolant.

1.
After the coolant has drained, tighten the radiator
drain plug securely. and installthe reserve tank
drain cap securely.
Fill the reserve tank to the MAX mark (A) with
Honda All Season Antifreeze/Coolant Tvpe 2
(P/N O1999-9001).
8. Pour Honda All Season Antifreeze/Coolant Type 2
into the radiator up to the base of the filler neck.
NOTE:. Always use Honda All Season Antifreeze/Coolant
Type 2 {P/N 01999-9001). Using a non-Honda
coolant can result in corrosion, causing the
cooling system to malfunction or fail.. Honda All Season Antifreeze/Coolant Type 2 is a
mixture of 50% antifreeze and 507o water. Pre-
mixing is not required.
Engine Coolant Refill Capacity including the
reserve tank capacity of 0.53 4 (0.56 US gtl :
5.0 0 (s.3 US qt)
Installthe radiator cap loosely.
Start the engine, and let it run until it warms up (the
radiator fan comes on at least twice).
Turn off the engine. Check the level in the radiator,
and add Honda All Season Antifreeze/Coolant Type
2 if needed.
Put the radiator cap on tightly, then run the engine
again and check for leaks.
lnstall the splash shield (see step 22 on page 5-12).

5. Disconnect the fan motor connectors and radiator fan switch connector, then pull the radiator up and out.
6. Remove the fan shroud assemblies and other parts from the radiator.
7. Installthe radiator in the reverse order of removal. Make sure the upper and lower cushions are set securelV.
8. Install the bulkhead in the reverse order of removal. Apply body paint to the bulkhead mounting bolts.
9. Fill the radiator with engine coolant and bleed the air (see page 10-6).

Recover the refrigerant with a recovery/recycling/
charging station (see page 21-53).
Remove the front bumper {see page 20-85).
Remove the bolts, then disconnect the discharge
line (A) and the condenser line (B) from the
condenser. Plug or cap the lines immediately after
disconnecting them to avoid moisture and dust
conlamtnaflon.

4, Remove the mounting bolts, then remove the
condenser by lifting it up. Be careful not to damage
the radiator or the condenser fins when removino
the condenser.

5.lnstallthe condenser in the reverse order of
removal, and note these items.
. lf you're installing a newcondenser, add
refrigerant oil (KElHlN SP- 10) lsee page 21'6).. Replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a (R-'134a)to avoid leakage.. lmmediately after using the oil, reinstallthe cap
on the container, and seal it to avoid moisture
absorption.. Do not spillthe refrigerant oil onthevehicle;it
may damage the paint. lf the refrigerant oil
contacts the paint, wash it off immediately.. Be careful not to damage the radiator or the
condenser fins when installing the condenser.. Charge the system (see page 21-55).
