Engine Coolant Refilling And Bleeding; '96 -00 Models - Acura 3.5 RL Manual

Engine Coolant Refilling and Bleeding

'96 -00 models:

CAUTION: When pouring engine coolant, be sure to
shut the relay box lid and not to let coolant spill on the
electrical parts or the paint. If any coolant spills, rinse it
off immediately.
NOTE:
Perform this procedure when the engine is cool.
Before replacing the coolant, turn the ignition ON (II),
slowly turn the climate control temperature knob to
90°, and turn off the ignition. This will allow the
coolant in the heater to drain out with the rest of the
system.
When the radiator is cool, remove the radiator cap.
Loosen the drain plug, and drain the coolant.
DRAIN CAP
2. Remove the drain cap from the coolant drain pipe
to drain the block.
3. Put the drain cap back in place, then reinstall the
clip on the drain cap securely.
4. Tighten the radiator drain plug securely.
5. Remove, drain and reinstall the reservoir. Fill the
tank halfway to the MAX mark with water, then up
to the MAX mark with antifreeze.
6. Mix the recommended antifreeze with an equal
amount of water in a clean container.

7. Remove the engine cover (see page 5-3).
8. Loosen the air bleed bolt in the water passage, then
fill the radiator to the bottom of the filler neck with
the coolant mixture. Tighten the bleed bolt as soon
as coolant starts to run out in a steady stream with-
out bubbles.
9. With the radiator cap off, start the engine and let it
run until it is warmed up (radiator fan comes on at
least twice). Then, if necessary, add more coolant mix
to bring the level back up to the bottom of the filler
neck.
10. Put the radiator cap on tightly, then run the engine
again and check for leaks.
Always use only genuine Honda antifreeze/
coolant.
For best corrosion protection, the coolant con-
centration must be maintained year-round at
50% minimum. Coolant concentrations less than
50% may not provide sufficient protection
against corrosion or freezing.
Coolant concentrations greater than 60% will
impair cooling efficiency and are not recom-
mended.
Do not mix different brands of antifreeze/coolants.
Do not use additional rust inhibitors or anti-rust
products; they may not be compatible with the
coolant.
