So I have this CJ7 that has some running issues. I feel like it's just a few things away from being a decent little weekend trail rig slash cruise around town rig. The first problem I need to address is keeping it running.
Going up AF canyon, the hill leading up before the Forest Lake trail caused it to overheat. It also can't run during the summer in stop and go traffic without overheating/vapor locking. It clearly needs better cooling. After some poking around for fans, it looks like this is the exact product the previous owner put in it...
Now, is it possible to just add a bigger fan, or am I better just replacing the radiator with a radiator/fan combo larger and with more CFM's? Or would a larger overflow bottle holding more coolant in the system make a difference (typing this, I'm not 100% sure it even has an overflow bottle now...I assume it does but I don't recall seeing it specifically...will check after work).
The second problem to address is TBI. Part of the problem I have is that the carb doesn't want to run at any angle, and elevation really ****s with it. I also think the fuel is getting too hot and the fuel lines might need to be re-routed and/or shielded where they are running close to the block and above the dual exhaust. (I kind of want to just get rid of the dual exhaust in favor of a single so that it isn't even an issue, but that might be more dollars than just shielding). So, in which order do I attack this? I was thinking of jumping to TBI and just seeing if that eliminates the issue all together, but maybe both of those problems need to be addressed at the same time?
After I can keep it running, I want to improve ride quality/offroad quality most likely by going to YJ springs and pushing the wheelbase 2" in both directions. But that's probably for a later discussion.

At that point, I'd work on adding TBI.
