I hate how that pull is against my thigh. I will consider removing it. I need to think if I really use them or not.

How hot are you???
I’ve got a heat issue, well in my mind it’s a heat issue.
very built AMC 360 with FiTech Efi along with V8 Be Cool aluminum radiator with mechanical fan and shroud. I’m running water wetter instead of coolant and on mild days I am at 215 degrees easily and get to 225 at stoplights. During the Summer months it’s worse. My timing is set right. I also run an 8274 on the front which blocks a lot of the air.
speedhut gauge and FiTech have separate gauges and both sensors are threaded on top of the manifold. They both show the same temps.
any ideas on how to bring the temps down? I don’t want to loose the 8274 but if I must I will.

At 5’9” I’m not a big guy but I do see where the pulls could be a problem. Turns out my door seals will be here by the end of the week. I’ll get them installed and see how it all fits.

Are you running the clutch fan? Maybe install a HD clutch that will lock up sooner?

I'd certainly pull the winch for a while to see if it's the issue before getting into anything else. I have an aluminum radiator on mine (just a stock 4.0) that runs so cool that the electric fan rarely runs unless I'm doing low-speed driving. I'm kind of shocked that even a built 360 with an 8274 would be a problem.
Try a lower thermostat to get things flowing sooner to let the radiator keep up better? Doubt it would help, but all I got other than Raymond's idea (or maybe a hard-mounted fan, eliminate the clutch?)

How's your fan to shroud clearance? The one picture I could find in the thread looks like the fan blades don't protrude very deep into the shroud and maybe are a bit far away from the edge? The tighter it is to the edge the more efficient it will be, and ideally should be 1/2 of pitch depth into the shroud.
May also throw a new radiator cap on. Sometimes if they won't seal pressure right things will boil over.

Great call-out. I have actually added a spacer and put my fan closer to the radiator - as close as I can get without hitting it.

Also since I am running an automatic I have hot tranny fluid running through my radiator. I also thought about adding a separate trans cooler as a last resort.
So maybe another question would be how hot is too hot? I've always heard 230 is tops for AMC V8s. The fact that I am approaching that with Water Wetter is what concerns me. Lord knows where I would be with regular coolant on a consistent basis. I changed to Water Wetter last September when sitting in traffic picking up my daughter at school I was at 230 for a brief period.

That's an idea. I do not have a clutch fan currently.
While I am not afraid to put more $$ into this build I also don't want to waste any at the same time. So I guess my next step would be to pull the winch for now, keeping the Water Wetter in place, and see if I see a drop in temps. If so, I could then drain the fluid, switch to coolant, and see what my temps are.

Are you currently running a flex fan? IMO clutch fans work much better and move way more air. My little 4.3 will get warm enough to engage the fan on long slow climbs in 90+ degree heat. It only stays on a minute or two and things are cooled off. The fan moves an incredible amount of air compared to the flex fan I had with the 258 prior. For what its worth I also have an 8274 blocking most of the grill.

Yea I was going to ask you after I saw the other post about your 8274.
I had a mild 304 in my last Scrambler with an 8274 and never had heat issues with the rest of the setup being identical to the current.
I probably have a clutch fan in storage

To follow-up to the heat issue my first mod I’m going to try is to add an auxiliary trans cooler. Having that hot fluid run through the radiator can’t be helping things.
To follow-up on the half doors I decided to get ready for the 80 degree temps we have forecasted for later this week.

Maybe it’s my age (46 next week), maybe it’s my love of muscle cars / anything 1970ish and older, AMC Jeeps, …. while I don’t like chrome on modern stuff I dig it on the older stuff.
Picked up a Laredo grill cover for The Family Man yesterday. Hopefully it cleans up nicely. There’s something about chrome on silver

Those are cool. I know your attention to detail so when you mount it please tell us how you attach it without damaging your paint.

Heat issues seem to be solved. Time will tell …..
now I have a new problem. I hope I didn’t jinx myself earlier talking about how I’ve had nothing but good things to say about FiTech and my experiences with them In both this Jeep and multiple others.
The Jeep sat for 3 months without being cranked. Since then I consistently loose fuel pressure when it sits more than an hour. This makes it hard to start. I can get it started…. Just isn’t fun.
called the tech line. Guy said to replace regulator in the Force Fuel and all things will be fine. Fine, it’s a $15 part. I did that. Same problem after.
called the tech line. Guy said I needed a check valve in the main fuel line. When I asked why I’ve never needed it before in 600 miles he said “dunno… but your issue is fuel leaking back out of Force Fuel.“. Fine, it’s a $6 part. I’ll do it. Guess what?? Same problem after.
called the tech line today. Guy said I need to service my Force Fuel filter. Said it probably got gummed up sitting for 3 months. Fine, it doesn’t cost $ just some time cleaning. I‘ll do it…. This weekend.
Stay tuned…….

Unfortunately, it sound like they need a new tech guy....
