1. Make sure the engine is cool, remove the radiator cap and drain the radiator- the drain plug on mine was on the passenger side.
  2. Remove the plastic covers over the radiator.
  3. Disconnect the radiator overflow reservoir hoses and remove the 3 nuts holding it in place.
  4. Disconnect the wire harness at the cooling fan and the upper and lower radiator hoses. I also had to remove some of the the blower piping for more room to work in there. While it was off I covered both exposed ends with aluminum foil to keep dirt and debris out.
  5. If your car is equipped with an automatic transmission, disconnect the cooler lines
  6. unbolt the upper radiator supports and remove them.
  7. Lift the radiator straight up and out of the car.
  8. Unbolt the cooling fan from the stock radiator and attach it to the new radiator. It may be easier to get the radiator out by removing the fan while the radiator is still in the car. I had to reinstall the fan after the Fluidyne was in the car because of clearance issues with the blower.
  9. Follow the above directions in reverse to install the new radiator. Fill the radiator with your preferred mixture of coolant/water and start the car. Once the thermostat opens (you can tell by feeling the upper radiator hose - when there is pressure in the hose the thermostat is open) carefully open the radiator and make sure it is full. I thought mine was but the low coolant light came on when I took the car for a test drive and mashed the go pedal...
   
These are the lower radiator supports along with some residual fluid...
This is the mounting peg that drops into the lower supports and the drain plug. This is the lower corner on the passenger side of the car... The same part on the Fluidyne...
The shiny new Fluidyne. It is a damn shame that something that looks this good has to be covered up...
