5. Locate and carefully remove the
engine oil level dipstick.
6. Wipe the dipstick clean. Insert
the dipstick fully, then remove it
again.
• If the oil level is between the
lower and upper holes, the oil
level is acceptable. DO NOT ADD
OIL.
• If the oil level is below the lower
hole, add enough oil to raise the
level within the lower and upper
holes.
• Oil levels above the upper hole
may cause engine damage. Some
oil must be removed from the
engine by an authorized dealer.
7. Put the dipstick back in and make
sure it is fully seated.
ENGINE AND INTERCOOLER COOLANT
The concentration and level of coolant should be checked at the mileage
intervals listed in the scheduled maintenance information. The coolant
concentration should be maintained at 50/50 coolant and water, which
equates to a freeze point of -34°F (-36°C) . Coolant concentration testing is
possible with a hydrometer or antifreeze tester (such as the Rotunda
Battery and Antifreeze Tester, 0014–R1060). The level of coolant should be
maintained at the "cold fill range" level in the coolant reservoir. If the level
falls below, add coolant per the instructions in the Adding coolant section.
Your vehicle was factory-filled with a 50/50 coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly. A
50/50 mixture of coolant and water provides the following:
• freeze protection down to -34°F (-36°C).
• boiling protection up to 265°F (129°C).
• protection against rust and other forms of corrosion.
• an accurate temperature readout from the engine coolant gauge.
