LUBRICATION
COOLING SYSTEM
ANTI-FREEZE
The cooling system of your new vehicle is filled at the
factory
with
IH
permanent-type
anti-freeze.
IH
permanent-type anti-freeze may be added undiluted if
protection below -290C (200F) is required.
CLEANING
Once a year the cooling system should be drained and
thoroughly flushed.
Unless the cooling system is treated with a corrosion
preventative, rust and scale will eventually clog up
passages in the radiator and water jackets. This
condition is aggravated in some localities by formation of
insoluble salts from the water used.
IH cleaning solutions are available which have proven
very successful in removing accumulation of rust, scale,
sludge and grease. This solution should be used
according to the recommendation on the container.
CAUTION
DO NOT USE CHEMICAL MIXTURES TO STOP
RADIATOR LEAKS EXCEPT IN AN EMERGENCY.
NEVER
USE
SUCH
SOLUTIONS
INSTEAD
OF
NEEDED RADIATOR REPAIR.
When draining the cooling solution, disconnect the
radiator outlet hose, as large particles of sediment will
not pass through the drain.
WARNING
USE ONLY THE FOLLOWING PROCEDURE TO
REMOVE THE PRESSURE TYPE CAP FROM THE
RADIATOR. ALWAYS ALLOW THE ENGINE TO COOL
FIRST. WRAP A THICK, HEAVY CLOTH AROUND THE
CAP. PUSH DOWN, LOOSEN CAP SLOWLY TO ITS
FIRST NOTCH POSITION; THEN PAUSE A MOMENT.
THIS WILL AVOID POSSIBLE SCALDING BY HOT
WATER OR STEAM. CONTINUE TO TURN CAP TO
THE LEFT AND REMOVE.
CAUTION
IF THE COOLANT SHOULD GET EXTREMELY LOW
AND THE ENGINE VERY HOT, LET THE ENGINE
COOL FOR APPROXIMATELY 15 MINUTES BEFORE
ADDING COOLANT; THEN, WITH THE ENGINE
RUNNING, ADD COOLANT SLOWLY. ADDING COLD
WATER TO A HOT ENGINE MAY CRACK THE
CYLINDER HEAD OR CRANKCASE.
