6B-6 ENGINE COOLING
COOLING SYSTEM FLUSH AND REFILL
WARNING:
To help avoid danger of being burned, do not remove radia-
tor cap while engine and radiator cap while engine and ra-
diator are still hot. Scalding fluid and steam can be blown
out under pressure if cap is taken off too soon.
1) Remove radiator cap when engine is cool:
Turn cap counterclockwise slowly until it reaches a “stop”.
(Do not press down while turning it.)
Wait until pressure is relieved (indicated by a hissing sound)
then press down on cap and continue to turn it counterclock-
wise.
2) With radiator cap removed, run engine until upper radiator
hose is hot (this shows that thermostat is open and coolant is
flowing through system).
3) Stop engine and open radiator drain plug (1) to drain coolant.
4) Close drain plug. Add water until system is filled and run engine
until upper radiator hose is hot again.
5) Repeat Steps 3) and 4) several times until drained liquid is
nearly colorless.
6) Drain system and then close radiator drain plug tightly.
7) Disconnect reservoir tank hose from radiator. Remove reser-
voir tank and pour out any fluid. Scrub and clean inside of tank
with soap and water.
Flush it well with clean water and drain. Reinstall tank and
hose.
8) add 50 / 50 mixture of GOLDEN CRUISER 1200 (Good quality
ethylene glycol anti-freeze) and water to radiator and tank.
Fill radiator to the base of radiator filler neck and reservoir tank
to “FULL” level mark. Reinstall reservoir tank cap.
9) Run engine, with radiator cap removed, until radiator upper
hose is hot.
10) With engine idling, add coolant to radiator until level reaches
the bottom of filler neck. Install radiator cap, making sure that
the ear of cap lines up with reservoir tank hose.

ON-VEHICLE SERVICE
WARNING:
Check to make sure that engine coolant temperature is
cold before removing any part of cooling system.
Also be sure to disconnect negative cord from battery ter-
minal before removing any part.
COOLING WATER PIPES OR HOSES
REMOVAL
1) Drain cooling system.
2) To remove these pipes or hoses, loosen screw on each pipe or
hose clip and pull hose end off.
INSTALLATION
Install removed parts in reverse order of removal procedure, noting
the following.
Tighten each clamp bolt securely.
Refill cooling system with proper coolant, referring to description
on COOLANT of MAINTENANCE.
THERMOSTAT
REMOVAL
1) Disconnect negative cable at battery.
2) Drain cooling system and tighten drain plug.
3) Disconnect thermostat cap (1) from thermostat case (2).

1. Return hose
2. Vapor hose
3. Feed hose
4. Fuel tank
ENGINE FUEL 6C-3
7) As fuel tank has no drain plug, drain fuel tank by pumping fuel
out through fuel tank filler or fuel tank inlet.
Use hand operated pump to drain fuel tank.
WARNING:
Never drain or store fuel in an open container to avoid
possibility of fire or explosion.
8) Disconnect fuel hoses from filter (5) and pipes.
WARNING:
A small amount of fuel may be released after fuel hose is
disconnected. In order reduce the chance of personal in-
jury, cover hose and pipe to be disconnected with a shop
cloth. Be sure to put that cloth in an approved container
when disconnection is completed.
9) Remove fuel tank from vehicle.
INSPECTION
After removing fuel tank, check hoses and pipes connected to fuel
tank for leaks, loose connections, deterioration or damage. Also
check for leaks from installation face of parts installed on fuel tank,
visually inspect fuel tank for leaks and damage.
Replace any damaged or malconditioned parts.
INSTALLATION
1) Install fuel pump assembly to fuel tank.
Use new gasket.
2) Install 2-way check valve to fuel tank directing its black nozzle
toward fuel tank.
3) Connect hoses and pipes to fuel tank.
4) Connect breather hose to fuel tank.
5) Install fuel tank to vehicle.
Tightening Torque
(a): 23 N
.m (2.3 kg-m, 17.0 lb-ft)
6) Connect fuel filler hose to tank and breather hose to filler neck.
7) Connect fuel hoses to filter and pipes.
8) Connect connectors of fuel tank wire harness.
9) Install rear seat cushion referring to Section 9.
10) Connect negative cable at battery.
11) With engine “OFF” and ignition switch “ON”, check for fuel
leaks.

EVAP Canister Inspection
WARNING:
DO NOT SUCK nozzles on EVAP canister. Fuel vapor inside
EVAP canister is harmful.
1) Check outside of EVAP canister visually.
2) Disconnect vacuum hoses from EVAP canister.
3) Check that there should be no restriction of flow through purge
pipe (2) and air pipe (3) when air is blown (4) into tank pipe (1).
If any faulty condition is found in above inspection replace.
PCV SYSTEM
NOTE:
Be sure to check that there is no obstruction in PCV valve or
its hoses before checking IAC duty, for obstructed PCV valve
or hose hampers its accurate adjustment.
PCV Hose Inspection
Check hoses for connection, leakage, clog and deterioration.
Replace as necessary.
PCV Valve Inspection
1) Disconnect PCV valve (1) from cylinder head cover and install
plug to head cover hole.
2) Run engine at idle.
3) Place your finger over end of PCV valve (1) to check for vacuum.
If there is no vacuum, check for clogged valve. Replace as nec-
essary.
4) After checking vacuum, stop engine and remove PCV valve (1).
Shake valve and listen for the rattle of check needle inside the
valve. If valve does not the rattle, replace valve.
5) After checking, remove plug and install PCV valve (1).
