REMOVAL & INSTALLATION



The radiators used in these vehicles are cross-flow types (horizontal tubes) designed for strength and good heat transfer capabilities. These radiators use plastic tanks which are supposed to be stronger than traditional brass tanks but are subject to damage by impact such as a slipped wrench or heat as from a torch.

The use of aluminum cylinder heads, intake manifolds and water pumps requires special corrosion protection. Chrysler recommends their MOPAR Antifreeze or equivalent for best cooling without corrosion. If coolant looses its color or becomes contaminated, drain, flush and replace with fresh properly mixed coolant solution. A 50/50 ethylene glycol with a silicate inhibitor and distilled water mix is recommended.

  1. Disconnect negative battery cable.
  2.  

  1. Place a drain pan under the radiator. Open the radiator drain located at the lower right side of the radiator. Use care. These are plastic parts. Do NOT use pliers to open the drain. Do not remove drain unless it leaks and needs replacement.

  15. Install the upper radiator crossmember and tighten the bolts to 21 ft. lbs. (28 Nm).
  16.  
  17. Install the cylinder block drain plugs on both sides of the engine block.
  18.  
  19. Attach the fan motor electrical connector and reconnect the negative battery cable.
  20.  
  21. Be sure that the radiator drain is closed. Open the thermostat bleed valve. Install a 1 / 4 -inch diameter clear hose that is approximately 48 inches in length, to the end of the bleed valve and the other end into a clean container.
  22.

  1. Slowly refill the coolant reservoir until a steady stream of coolant flows out of the thermostat bleed valve. Gently squeeze the upper radiator hose until all of the air is removed from the system.
  2.  
  3. Close the bleed valve and continue to fill up the coolant reservoir bottle to the proper level. Install the cap back on the bottle and remove the hose from the bleed valve.

  1. Start the engine and allow to run until normal operating temperature is reached.
  2.  
  3. Check the cooling system and automatic transaxle for leaks and correct fluid level. Be sure that the thermostat bleed valve is closed once the cooling system has been bled of any trapped air.
