Important!
Do not loosen or open the radiator cap when coolant is hot.
Doing so may cause hot water or steam to splash out, resulting
in burn. W hen opening the radiator cap, be sure to confirm the
coolant is cold. Cover a thick cloth over the cap and loosen it
slowly to reduce pressure, then open the cap.
6. Close the radiator cap firmly and run the engine at approx. 2000 rpm. In addition, set the heater temperature
adjuster to the max position to circulate coolant in the
heater conduit system.
7. Confirm that the temperature gauge reads half or more of full scale and that the thermostat is activated.
Then continue idling 5 minutes more and switch off the
engine, and allow it to cool.
8. After the engine cools down, check the coolant level and refill it if necessary. W hen the level is lowered extremely,
check the coolant conduit system and reservoir hose for
leak.
9. Pour coolant into the reservoir to MAX level.






Refill Coolant
Important!
After closing the cooling system, let engine run warm until
thermostat opens (coolant approx. 92 °C/197.6F)

Inspection
Coolant level
Allow engine to cool. If necessary, refill coolant.

Check that cooling system self-bleeds during engine warming-
up phase.

Reuse of Quick–Connector
• Replace the port and connector if scratch, dent or
crack is found.
• Remove any dirt build up on the port when installing the connector. Replace the connector, if there is an
y
forms of rust, dent, scratch.
•
After cleaning the port, insert it straight into the
connector until it clicks. After it clicks, try pulling at
49N (5kgf) it out to make sure that it is not drawn
and is securely locked.

Assembling Advice
By applying engine oil or light oil to the pipe, port makes
pipe assembly easier. The pipe assembly should take
place immediately after applying oil (to prevent dust
from sticking to the pipe surface – which ma
y
decrease sealing ability).
Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the “ON" position and listen
for pump start-up sound. Inspect for leaks, the
fuel pressure will increase as the fuel pump is
actuated.
3. Perform leak inspection (step 2) several times.
4. Start the engine and observe the engine idle speed.
The presence of dirt in the fuel system may affect
the fuel injection system.

6C-12 ENGINE FUEL (C24SE)
Fuel Pump Relay
General Description
In order to control the fuel pump and sender assembly
(FPAS) operation, the FPAS relay is provided. W hen
the starter switch is turned to “ON" position, the FPAS
relay operates the FPAS for 2 seconds.
W hen it is turned to “START" position, the Engine
Control Module receives the reference pulse from the
Ignition Control Module and it operates the relay, again
causing the FPAS to feed fuel.
