How would you replace the radiator on a 1991 Geo Prizm 1.6L?

If you have an automatic transmisssion, there are two lines that have to be removed. Relatively easy as there should be two clamps that have to be loosened and then the rubber line can be pulled off. Be sure to tie them up as tranny fluid with otherwise leak out.Allow the engine to cool, if necessary. Remove the radiator cap. Remove the passenger side splash guard from under the car. On the on the engine side of the radiator, near the bottom, on the passenger side, is a petcock bolt. Loosen this bolt to drain all the radiator fluid. Clean up any spills so no critters, human or otherwise, try to drink it or sue you cause it's on the ground. Disconnect the radiator fan at the wiring harness near the radiator on the drivers' side. Disconnect the upper and lower radiator hoses wherever it's easiest for you. (if they feel flimsy or too squishy or you even THINK they'll fail, replace them. If you lose a hose on the freeway that engine will overheat and warp the head faster than you will be able to stop the car. On that you can trust me). On top of the radiator there are two brackets that hold it to the car. Remove these. Don't worry about the bottom, there's nothing there to worry about. Just yank 'er out.
