Cooling System - Acura Integra 1987 Manual

Cooling System

The engine in your Acura contains a number of aluminum parts.
Therefore, it requires an anti-freeze/coolant specifically for­
mulated to protect the aluminum parts from corrosion. Failure to
use a suitable anti-freeze/coolant may seriously shorten the life of
the engine as the result of rapid corrosion damage. Some anti-
freeze/coolants, although labelled for use in engines containing
aluminum, may not provide adequate protection for your engine.
Therefore, use only an anti-freeze/coolant recommended by the
Acura Automobile Division.
CHECK WITH YOUR ACURA DEALER.
For best corrosion protection, the mixture of coolant and water
must be maintained year-round at 50/50. Concentrations less than
50% coolant may not provide sufficient protection against cor­
rosion and freezing. Concentrations of greater than 60% coolant
will impair cooling efficiency and are not recommended. Low-
mineral drinking water or distilled water should be mixed with the
anti-freeze/coolant. Coolant loss should be replenished by a
mixture containing the proper concentration of anti-freeze and
water.
Do not mix different anti-freeze/coolants.
Do not use additional rust inhibitors or anti-rust products, as they
may not be compatible with the radiator coolant.

Checking Coolant
Check the coolant level in the reserve tank when the engine is at
normal operating temperature.
'Hi'WARNING
Do not remove the radiator cap when the engine is hot;
the coolant is under pressure and could severely scald you.
• If the level is below the MAX
mark, but still visible, add a
50/50 solution of anti-freeze
and water to bring it up to
MAX.
• If there is no coolant in the
reserve tank, the cooling sys­
tem should be checked for
leaks and repaired if necessary.
Coolant must then be added
to the radiator.
