WARNING!(Continued)
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.

the radiator is hot.
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
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.
CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine dam-
age and may decrease corrosion protection. Organic
Additive Technology (OAT) engine coolant is differ-
ent and should not be mixed with Hybrid Organic
