I have a V6 and i had to replace my radiator two weeks ago cuz i had a small hole in the radiator core. I am not sure if the set up for the radiator is the same for the 4cy and the V6. First remove the upper hose. Then u need to remove the hold downs for the radiator and shroud. My radiator fan is powered by power steering fluid so i had to remove the power streeting hose that ran in to the radiator fan motor. then i had to remove the hose coming out of the fan. Once i had that removed i could remove the fan shourd (which is held in place by 4 bolts). With that off i disconnected the lower radiator hose from the radiator. Then i disconnected the transmission lines going in to the radiator. Once all that is off all u have to do is pull out the radiator. It wasn't that bad the only thing is that it was really messy and i lost alot of fluids ie. coolant, transmission fluid, and powersteering fluid. Good luck. If ur good with cars its not something u should struggle with.
