You have an OEM style 3 core replacement radiator with a fixed 4 blade fan and spacer. No shroud needed.

As a general rule, the 5 and 7 blade fans that have fan clutches use the shrouds.

That's the same setup I have with no shroud, and the highest temp I have ever seen was 205 while wheeling on a 95* day. It normally runs about 170.

Are you having cooling problems?

A few years back I had a problem finding one. I ended up getting one through OK4WD. I called and spoke with Mike and he helped me out. Give a call. Maybe he can find the right one for you.

As the others already said, your Jeep didn't come from the factory with a shroud. How warm is overheating? 258s run fairly warm. Mine goes all day at 190°.

Are you saying the sand clogs the radiator?

I'd rather be lost on the trails than found at home!

not sure what the temp gets up to numerically but the temp gauge gets almost all the way to the right

Rod-out the radiator.
After that, use distilled water only with coolant.

Let more air out of your tires. When you've let out enough, you should be able to run in 4-hi with no overheating. Try somewhere between 10-12 psi.

I agree with LumpyGrits. Do some maintenance to the cooling system. I'd do a good back flush of the entire cooling system. Probably replace the thermostat too (they're cheap). I've been running my CJ for 20+ years without a shroud and never come close to over heating. Even out at Sand Dunes National Monument in August (read sand, heat and altitude), my temp gauge stays close to the middle.

Even if you wanted to install a shroud as long as that cooler is strapped to the back side of the radiator it would not fit.
a fan shroud will not solve your heating problem in my opinion. You have other issues going on there. I had the same set up as you and my gauge never moved more than a needles width once it reached running temp.
Here are a few things to check:
Check your timing if its too retarded that will run the engine hot as Hades.
thermostat might not be working right or stuck or missing.
A missing t/stat will run an engine hot due to coolant flowing too fast through the rad.
Radiator plugged or partially plugged.
loose belts.
lower radiator hose collapsing.
water pump Failing.
Bad sender or gauge. (only telling you its hot but not really)

^^^I agree^^^ Most likely cheaper than a new radiator and you'll probably have a better product.
