MAINTENANCE/SERVICE
Engine Cooling System
COOLANT LEVEL
Check coolant level daily at reserve tank (A).
Check level when engine is cold.
If tank is less than half full, add coolant to reserve
tank (A), not to radiator.
IMPORTANT: Use a 50/50 mix of clean, soft water
and anti-freeze. This ratio will protect engine to
temperatures of -30
°F (-34°C). Anti-freeze
Specification: Ethylene-glycol or propylene-glycol
fully formulated, containing a pre-charge
supplemental coolant additive (SCA) and meeting
ASTM Designation: D 4985.
Anti-freeze is essential in any climate. It broadens
the operating temperature range by lowering the
coolant freezing point and by raising its boiling
point. Anti-freeze also contains rust inhibitors and
other additives to prolong engine life.
IMPORTANT: If anti-freeze strength is not
adequate, do not drain cooling system to protect
against freezing. System may not drain
completely, and damage from freezing could still
result.
RADIATOR CAP
The radiator cap must fit tightly and the cap gasket
must be in good condition to maintain the 7 psi (58
kPa) pressure in the cooling system.
CAUTION: To avoid personal injury
from hot coolant, do not turn radiator
cap until engine has cooled.
Turn the cap to the first notch to relieve
pressure before removing cap completely.
If it becomes necessary to add coolant to the
radiator, use a ladder as shown.
ANTI-FREEZE CONCENTRATION
Check the anti-freeze concentration with a tester
once per season, preferably before off-season
storage. Protect the engine to -30
°F (-34°C) with a
50/50 anti-freeze and water mixture.
