Any change your radiators for a Grand Jeep Cherokee 1998

Most yards use an interchange guide to give compatible years. You can check on any online scrap yard site for such listings, even an auto parts store can look up compatible years. As a rule of thumb, the same generation of vehicle will exchange parts. A '98 is still a first generation, so 1993-98 would likely work, but that doesn't mean later model years wouldn't also work. I'm not a fan of used radiators, they can be more trouble than their worth and new ones can be had for 100-200.
