Taking Built CJ7 apart to make CJ8 For Winter Use

Needed to replace the electric fan and be cool radiator. Radiators are a touchy subject with me. Was going to go back to the be cool radiator but 2 to 3 months is a long time to wait for a radiator. Trying a engineered cooling products radiator. Design is more like the original radiators (top and bottom tanks). When I got the radiator workmanship looks good. Especially where the core meets the tanks. Most that I've come across that's where they leak. These look like a more solid weld. Mount was straight forward, had to make new mounts for the electric fan.20211009_100047_resized.jpg20211009_102221_resized.jpg20211009_131531_resized.jpg20211009_143640_resized.jpg20211010_113037_resized.jpg
 
I have an ECP in mine that’s been great. With the electric fan I have it cools crazy fast and the fan doesn’t really run at all in cool weather or at any speed on the road.
 
Not comfortable with using the auto trans cooler with this radiator. The be cool fitting is a 3/8" fitting, the engineered cooling products fittings needed to be 1/4" fitting. I don't want to reduce the flow. The be cool radiator I ran it through the radiator, then a external cooler. This one I'm skipping the radiator, just using the external cooler.20211015_095331_resized.jpg20211015_095350_resized.jpg20211018_190447_resized.jpg
 
Also installed new upper and lower hoses. I would have loved to get their fan setup. but I don't have the clearance. Big W, your the one that I got the idea to check them out :wave: Thanks. I can't tell you how many radiators I've gone through with my 2 trucks over the last 3 yrs (hint 6, two are still in the trucks). I'm hoping a stronger weld where the core mounts to the tank is the answer.
 
Your correct on cooling. On the be cool and this one I don't use a shroud, 3000 cfm fan. On the be cool once the temp hit 180, doesn't really shut off. On the new radiator in city driving 55 deg I watch the temp go from 190 down to 170. Temp sensor is 185 on, 175 off. Never had it shut off in city driving. I admit, jeep is usually parked when it gets to 50 deg weather. Now I'm putting a new fan temp control to take advantage of the extra cooling (with out the fan).

IMO, from what I've read the in-radiator tank is as much for warming up the trans as it is cooling, if for cooling at all. Auto transmissions want to be a certain amount of warm and I'd worry about skipping the radiator unless you just don't see any cool weather. I run both and have never had any issues with my trans temps, as judged by the sender I have in the trans pan.

Forgot the title, for winter use I would never skip the radiator.
