Engine Coolant Refilling and Bleeding
1. Slide the heater lemperature control lever to maxi
mum heat.
Make sure the engine and radiator are cooi to the
touch.
2. Remove the radiator caP.
3. Loosen the drain plug, and drain the coolant.
4. Remove the drain bolt from the cylinder block.

Engine Coolant Refilling and Bleeding (cont'dl
Mix the recommended antifreeze with an equal
amount of water in a clean container.
NOTE:
. Always use Genuine Honda Antifreeze/Coolant.
Using a non-Honda coolant can result in corro-s\on, ca

o. fail.
For best corrosion protection, the coolant con-
centration must be maintained year-round at50% minimum. Coolant concentrations less than
50% may not provide sufficient protection against
corrosion or freezing. Coolant concentrationsgreater than 60% will impair cooling efficiency
and are not recommended.
Do not use additional rust inhibitors or anti-rustproducts; they may not be compatible with the
coolant.

9. Pour coolant into the radiator uD to the base of the
filler neck. When pouring engine coolant. do not let
coolant spill on any electrical pans or the paint. lf
any coolant spills, rinse it oft immediately.
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,
add coolant if needed.
Put the radiator cap on tightly. then run the engine
again and check for leaks.

Cap Testing
1.
2.
Remove the radiator cap, wet its seal with engine
coolant, then install it on the pressure tester.
Apply a pressure of 93 - 123 kPa (0.95 - 1.25 kgflcm',
14 - 18 psi).
Check for a drop in pressure.
lf the pressure drops, repiace the cap.

Testing
1.Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top oI the filler neck.
Attach the pressure tester to the radiator, and apply
a pressure of 93 - 123 kPa (0.95 - 1,25 kgf/cm', 14 -
18 psi).
Inspect for engine coolant leaks and a drop in pres-
sure.
Remove the tester, and reinstall the radiator cap.
Check for engine oil in the coolant and/or coolant in
the engine oil.

Testing
Replace the thermostat if it is open at room temperature.
To test a closed thermostat:
1. Suspend the thermostat in a container of water. Do
not let the thermometer touch the bottom of the hot
container.
THERMOMETER
THERMOSTAT
Heat the water, and check the temperature with a
thermometer. Check the temperature at which the
thermostat first opens, and at which it is fully open.
Measure the lift height of the thermostat when fully
open.
STANDARD THERMOSTAT
Lift height: above 8.0 mm (0.31 in)
Starts opening: 169 - 176'F (76 - 80'C)
Fully open: 194'F (90'C)

Remove the timing belt (see section 6)
Turn the water pump pulley counterclockwise.
Check that it turns freely.
Check for signs of seal leakage.
NOTE: A small amount ol "weeping" from the bleed
hole is normal.

Fan Motor Testing
1. Disconnect the 2P connector.

Test the motor by connecting battery power to theNo. 2 terminal and ground to the No. 1 terminal.
lf the motor fails to run or does not run smoothly,reptace rt.

Radiator Fan Switch Testing
E@ Removing the radiator fan switch whilethe engine is hot can cause the coolant to spray out, seri-ously scalding you. Always let the enginc and radiatorcool down before removing the radiator fan switch.
1. Remove the radiator fan switch from the thermostathousing (see page 10 '10).
2. Suspend the radiator fan switch in a container ofwater as shown.
Heat the water, and check the temperature with athermometer. Do not let the thermometer touch thebottom of the hot container.
Measure the continuity between the A and B termi-nals according to the table.
Bleed the air from the cooling system after installingthe radiator fan switch (see page 10-5).

Goolant Temperature Gauge
Gauge Testing
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testin9.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire from the coolant tempera-
ture sending unit. and ground it with a jumper wire.
YEL/GRNWIRE
Turn the ignition switch ON {ll). Check that the
pointer of the coolant temperature gauge starts
moving toward the "H" mark. Turn the ignition
switch OFF before the pointer reaches "H" on the
gauge dial. Failure to do so may damage the gauge.
lf the pointer of the gauge does not move at all,
check for an open in the YEL/GRN wire.
lf the wires are OK, replace the coolant temperature
gauge.
lf the coolant temperature gauge works, test the
coolant temperature sending unit.

the cooling system. lf the cooling system is OK,
replace the sending unit.
