434 SERVICING AND MAINTENANCE
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be drained, flushed and
refilled with fresh coolant. Check the front of the A/C
condenser (if equipped) or radiator for any accumulation of
bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the A/C
condenser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant properly.
Failure to fill these systems properly could lead to severe
internal engine damage. If any coolant is needed to be added
to the system please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Plan” in this section for the proper
maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
NOTE:
• Mixing of engine coolant (antifreeze) other than specified
Organic Additive Technology (OAT) engine coolant (anti-
freeze), may result in engine damage and may decrease
corrosion protection. Organic Additive Technology (OAT)
engine coolant is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze) or any “globally compatible” coolant
(antifreeze). If a non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an emergency, the
cooling system will need to be drained, flushed, and
refilled with fresh OAT coolant (conforming to MS.90032),
by an authorized dealer as soon as possible.
