ENGINE COOLANT / RADIATOR CAP

E2-6prose procedure

Use the proper amount and mixture of ethylene-glycol based coolant. (Refer to Coolant Protection, page E2-5.)

1
Slowly pour the coolant into the radiator up to the coolant filler port.
Filling pace: 1.0 L {1.1 US qt, 0.9 Imp qt}/min. max.
2
Fill the coolant reservoir up to the FULL mark.
3
Fully install the coolant filler cap.
4
Start the engine and let it idle until it warms up.
5
If the temperature increases beyond normal, there is excessive air in the system. Stop the engine and allow it to cool; then repeat steps 1-3.
6
Run the engine at 2,200—2,800 rpm for five minutes.
7
Stop the engine and allow it to cool.
8
Repeat steps 1-7; then go to step 9.
9
Remove the filler cap and verify that the engine coolant level is near the filler neck. If not, repeat steps 1-8.
10
Fill the reservoir up to the FULL mark.

1
Remove foreign material (such as water residue) from between the radiator cap valve and the valve seat.
2
Attach the radiator cap to a radiator cap tester with the SST. Apply pressure gradually to 73.5–102 kPa {0.75–1.05 kgf/cm2, 10.7–14.9 psi}.
3
Wait about 10 seconds. Verify that the pressure has not decreased.

1
Pull the negative pressure valve to open it. Verify that it closes completely when released.
2
Check for damage on the contact surfaces and for cracked or deformed seal packing.
3
Replace the radiator cap if necessary.
