CAUTION: The system is under high pressure when the
engine is hot. To avoid danger ol releasing scalding engine
coolant, remove the cap only when the engine is cool.

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.

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

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.

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).
