Question type: Maintenance & Repair

Can I put a smaller radiator in to replace a
bigger one.  

3 Answers


Usually it is the other way around, putting in a bigger radiator to replace the small one. I would not do it, an engine needs all th cooling it can get with today's engines running so lean and hot, cooling is not something you want to downsize.
