pulling the engine without pulling the radiator?
well....
i wouldn't advise that, not even sure its possible.
Once you get the engine loose from the tranny it has to be pulled back to clear the transmission case. I suppose if you removed the fan and alternator and fan shroud you MIGHT get enough clearance to get it out. But by the time you do all that you could have just pulled the radiator, its only 4 hoses, (5 if you include the reservoir hose), and a couple of bolts. All it would take is one wrong move and you got a hole in the radiator core, why take the risk? Just pull it. New radiators are 600 to 800 dollars and a new core is half of that plus the labor to replace it. Not worth the risk imo.
