Fan shroud wanted?

[cj69RR]

Thinking that I need a fan shroud on this car now. Didn't really have any issues with it when it was out in Colorado but seems to heat up a little in stop and go traffic but cools off right after it gets moving again. The front lower spoiler I put on seems to help but it has to be moving. Has the stock belt setup with water pump and alternator is all, running a flex a lite flex fan. Thinking the fan shroud will help? Suggestions also welcome.

What size radiator?

Guess that would have helped, especially since I put everything else. It's the 22 inch wide radiator.
