Can a 99 radiator leak be repaired or must the whole radiator be replaced? Please help. Fuel pump, radiator, alternator and battery went as same time.

 

If the plastic end caps are where the leak is, then I'd recommend replacement, if it's in the center, then a radiator shop should be able to repair it. Also replace your thermostat and flush the cooling when you put the repaired/replaced radiator in
