Removal & Installation



2.0L Engine

CAUTION
Never open a radiator cap or cooling system when the coolant temperature is above 100°F (38°C). Avoid physical contact at all times, wear protective clothing and eye protection. Always drain coolant into a sealable container. If spillage occurs take care to clean the spill as quickly as possible.

  1. Drain the coolant into a sealable container by loosening the radiator drain plug.
  2.  
  3. Remove the upper and lower radiator hoses.
  4.  
  5. If equipped with an automatic transaxle, place a separate sealable drain container under the transaxle Automatic Transmission Fluid (ATF) cooling lines and disconnect, drain and plug the lines and radiator fittings.
  6.  
  7. Detach the electrical connectors for the radiator cooling fans.
  8.  
  9. Remove the two upper radiator support brackets and cushion assemblies.
  10.  
  11. Carefully lift the radiator upward and away from the vehicle.
  12.  
  13. Remove the fasteners that secure the cooling fans to the radiator.
  14.  

To install:

  1. Install the radiator in the reverse order of disassembly.
  2.  
  3. Set the heater to the full hot position.
  4.  
  5. Fill the cooling system with a 50/50 mixture of a suitable coolant and water and bleed the air out of the system as necessary. Alternately squeeze the upper and lower radiator hoses to help force out any trapped air pockets.
    NOTE
    When mixing a 50/50 solution of coolant and water, using distilled water instead of regular tap water may help prevent the cooling system from internal deposit build-up.

  6.  
  7. With the radiator cap partially installed, start the engine, and allow the engine to run until the cooling fan runs two times. Turn the engine off and top up the cooling system and overflow reservoir as necessary.
  8.  
  9. Close the radiator cap, restart the engine and check for leaks.
