    there,s nothing to it. all you do is drain the anti-freeze, take the transmission lines off, take the top and bottom radiator hoses off, take the top radiator support off and the radiator should lift right out. tell him not to lose the rubber mounts that the radiator sits on.

    This should not be very hard at all. You need to drain the radiator, then the bottom hose into a bucket ( do not disguard in lawn or drain) dogs like the sweat taste of this stuff and it will kill them, also not in drain because it’s wrong, take it to a auto store that takes hazard waste. Now disconnect top hose and disassemble radiator from engine, it might have a trans line cooler, that need to come off and temp plug it. also take the electric fan or fan off place all hard wear in bowels with labels, ig, rad, fan, etc, etc. Now put in the new one in and work backwards. when you put the water in go with 50/50 mix or check with auto store for specs and type of fluid, try to use distilled water it’s better for the radiator and system. Run the car and leave the cap off to purge the system ie, get the air out. and your done. then fill the over flow bottle.
