FLUID RECOMMENDATION



A 50/50 mixture of water and a high-quality ethylene glycol type antifreeze that is safe for use in aluminum components is recommended. The 50/50 mixture offers protection to -37°F (-40°C). If additional cold weather protection is necessary a concentration of no more than 70% antifreeze may be used.

LEVEL CHECK

Fig. Fig. 1: Adding coolant through the fill cap of the reserve tank

All vehicles are equipped with a transparent coolant reserve container. A minimum and maximum level mark are provided for a quick visual check of the coolant level.

  1. Run the engine until normal operating temperature is reached.
  2.  
  3. Open the hood and observe the level of the coolant in the reserve.
  4.  
  5. Fluid level should be between the two lines. Add coolant, if necessary, through the fill cap of the reserve tank.
  6.  

DRAIN & REFILL



See Figures 2 and 3


CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. Without removing the radiator pressure cap and the system not under pressure, turn the engine OFF , then raise and safely support the vehicle on jackstands.

Fig. Fig. 2: After placing a drain pan underneath the drain hose, open up the radiator draincock and allow the cooling system to drain

  1. Place a drain pan underneath the radiator drain hose and open the radiator draincock located on the lower left side of the radiator.
  2.  
  3. The coolant recovery/reserve container should empty out first, then remove the radiator pressure cap.
  4.  

Removal of the coolant sensor on the 2.4L engine is required because the thermostat does not have an air bleed vent. Removal of the sensor allows an air bleed for coolant to drain from the engine block.

  1. To vent the engine, remove the coolant temperature sensor located above the water outlet housing on the 2.4L engine, or loosen the air bleed vent screw located on the thermostat housing on 3.0L, 3.3L and 3.8L engines.
  2.  
  3. Fill the system with a 50 / 50 mixture of clean ethylene glycol antifreeze and water until the system is full.
  4.  
  5. When coolant reaches the coolant sensor opening on the 2.4L engine, install the sensor, then continue filling up the system until it is full.
  6.  


WARNING
Be careful not to spill coolant on the alternator or drive belts.

  1. Fill the coolant recovery/reserve container with a 50 / 50 mixture of clean ethylene glycol antifreeze and water until it reaches the MAX mark.
  2.  
  3. It may be necessary to add coolant to the recovery/reserve container after 3-4 warm up/cool down cycles to maintain the coolant level between the MIN and MAX marks. This will remove any trapped air from the system.
  4.  

FLUSHING & CLEANING THE SYSTEM



  1. Drain the cooling system and refill with clean water only.
  2.  
  3. Install the radiator cap, then start the engine.
  4.  
  5. Allow it to run until the upper radiator hose is hot.
  6.  
  7. Stop the engine and drain the system.
  8.  
  9. If the water is dirty, refill the system, run the engine, then drain the system again. Continue to do this until the water drains clear.
  10.  
  11. After the water drains clear, refill the system with a 50 / 50 mixture of clean antifreeze and water.
