Just picked up 2000 4runner. Love it!! The last owner put an aftermarket rant cooler which is better. But he never plugged the old ports/holes on the radiator now there is some coolant dripping out. Obviously it's leaking inside somewhere. I guess I can just plug up the old port holes.

 

You can run some cooler hose between the two ports for now. I'd replace the rad.

 

I agree, I bought a Koyo A1998 38,000 miles ago and it's still working like new.
