COOLING SYSTEM
Fill the system with the recommended coolant through
the filler opening up to filler neck [1]. [1] [2]
Remove the radiator reserve tank cap [2] and fill the
reserve tank to the upper level line.
Bleed air from the system as follows:
1. Shift the transmission into neutral.
Start the engine and let it idle for 2 – 3 minutes.
2. Snap the throttle 3 or 4 times to bleed air from the
system.
3. Stop the engine and add coolant up to the filler neck
if necessary.
4. Install the radiator cap.
5. Check the level of coolant in the reserve tank and fill
to the upper level line if it is low (page 3-14).

• When air bleeding is insufficient, level of coolant in
the reserve tank will decrease. If so, fill to the upper
level line with coolant.
After installation, check that there are no coolant leaks.
Install the removed parts in the reverse order of
removal.
