Hello again folks,

It's been quite a while since I've posted here on the forums but I'd like to share the procedure on replacing the radiator on a '04 LeSabre


1) Drain the engine coolant.

2) Remove the upper radiator seal.

3) Remove the upper tie bar.

4) Disconnect the coolant overflow hose from the radiator.

5) Plug the coolant overflow hose.

6) Disconnect the upper and lower radiator hoses.

7) Remove the transaxle oil cooler pipe bracket bolt from the lower tie bar.

8) Remove the cooling fans.

9) Slide the plastic cap off the transaxle oil cooler pipe quick connect fittings.

10) Disconnect the upper and lower transaxle oil cooler pipes from the radiator.

11) Remove the A/C condenser mounting bolts.

12) Separate the condenser from the radiator.

13) Lift the radiator up and out of the vehicle.


To install:


1) Install the radiator to the vehicle. Place the bottom of the radiator in the lower pads.

2) Install the condenser to the radiator.

3) Install the A/C condenser mounting bolts and tighten to 115 inch lbs. (13 Nm).

4) Push the upper and lower transaxle oil cooler pipes into the radiator quick connect fittings, until a "click" is heard.

5) Tug gently on the cooler pipes to ensure proper retention.

6) Slide the plastic caps (1) over the quick connect joints.

7) Install the cooling fans.

8) Install the transaxle oil cooler pipe bracket bolt to the lower tie bar and tighten to 89 inch lbs. (10 Nm).

9) Install the upper and lower radiator hoses.

10) Connect the coolant recovery hose to the radiator neck.

11) Install the upper tie bar.

12) Install the upper radiator seal.
