Radiator Leak

[nextrio]

I have a 93 chevy silverado and the radiator will not stop leaking in the mornings when i start it. I have tried putting stop leak in it and it will not stop. It only does it when i start it, not when it is just sitting there.

are you sure it's leaking at the radiator?? if it is you'll have to replace it or get it repaired. flush the cooling system before installing the new radiator because that stop leak stuff clogs up cooling passages and might jam up the thermostat and heater core. common coolant leaks include waterpump, hoses, block heater, freeze plugs. be sure it's a bad radiator before replacing it.
