I had to replace my radiator. The replacement is engine oil cooler equipped whereas my original isn't. Can I plug the engine oil cooler "holes" and use the radiator or do I need to get one that is not - engine oil cooler. happy new year.

 

Should be no problem sealing the holes. I would use a gasket compound on the plugs that came with the radiator to keep any contaminants out of it. OR add the cooler hardware to your current rig and take advantage of the radiator.
