Winterbeater is right, BIG gaps around radiator. (recirculating hot air!)
What I did is stuff some foam weatherstrip into the gaps. Should be a firm snug fit so it holds itself in place, yet easy to pull out when maint requires.
Around the ends of the radiator I cut to fit ( about 12-14 inch long) pieces of 2 1/4 x 2 1/4 x 42 inch window air conditioner weatherstrip (about $5) from Home Depot/Lowes. Grey/Black color blends in ok . Use some smaller size foam for the gaps running across.
----------------------
I suspect air flow problems are a really BIG part of our cooling systems problems.
Just looking at it - that radiator is about the size to be expected for that size (HP) engine (or maybe a little smaller!) Other vehicles don't have this constant battle with cooling
--SO What the heck is not right on Cherokees??????--
Sealing the gaps and going to that ZJ HD fan cluch that Joe Peters suggests may really be the best start on gaining control of the problems. (assuming up to date coolant, flushed clean, Cleaning out the fins on the radiator!etc.)
