Not surprised it was getting hot. The engine bay is fully stuffed with a big heater and the airflow is 3/4 blocked with a big winch. The original arrangement with the straight 6 and no winch was just adequate in summer heat. Now you need a good off-road test to prove you got it right and don't forget to record it, lol.😉😉

[@Cyruscosmo]

Back in the day... around 84 or so when my friends and I were into wheeling I had a 1954 Willies Overland. It had the original radiator but I had fitted a Ford 302 in place of the old L head four-cylinder. During the summer in eastern Washington, it got a lot hotter then here in the seattle area and I had over heating issues when on camping trips and wheeling in the mountains. My solution was a ten foot section of 2 inch copper pipe cut in the middle and folded back on itself with a 90 degree fitting running along the underside of the truck tucked up next to the frame. Being a welder I slotted the tubes in a chevron pattern and brazed in 1/16th inch flat stock. A manifold placed in line with the heater hoses made it possible to divert all the water through the frame radiator or close it off so the water only went to the heater in the cab. There was no extra room under the hood for a wider radiator so I would have had to have a multi-core radiator custom built which was very expensive for a 20-year-old. It worked great until I shoehorned a 460 into it with a C6 and an NP 205 transfer case. I added another "radiator" on the drivers' side frame and all was cool again. Then I started breaking axles, LOL. it worked beautifully until one cold winter we went wheeling and I forgot to check my antifreeze freeze temp. One of the frame rads froze and blew antifreeze all over the front tire, I lost steering control and rammed into a snow bank... End of Willies... R.I.P. I miss that truck and all the fun we had together.

Paul, your fan shroud is doing nothing but blocking airflow, so about 1/2 of your radiator is just dead air space. A shroud is supposed to direct air movement to the parts of the radiator not directly in front of the fan, not be a solid barrier right up against the radiator. You'd be better off with out it and just having the fan hang in the middle. If you find yourself still overheating, that's why. 19:07 "It's pulling the whole radiator" he said as the cloth isn't getting pull into the top right corner, I noticed that's where you did an awkward edit.

[@larryjones3846]

i would have put the lip towards the rad. that way you have a small air gap between the rad and shroud, more air flow !!

[@auldman]

Pondering - putting the road sign so close to the rad surely blocks 20-25% of the rad from having cooling air flowing through it. Would it not be better to flip the road sign so the yellow side is by the fan thereby giving a 1/2"-3/4" stand off to let air flow across whole area of the rad? With the front bodywork off, there will be more airflow, so not a real test. You may have to cut a few louvres to allow the air to flow better out of the engine bay.

[@MrPaddyelvis]

Yep, exactly what I was thinking too.

Really liked the explanation of why you went with that fan. It’s useful to me to hear your reasoning

[@aussiebloke609]

A good fan is necessary when crawling at low speeds, but irrelevant for driving speeds - the vehicle pushing through the air has much more effect than the fan. If you're overheating at normal driving speeds, either the original shroud was too restrictive and reducing the amount of _passive_ air flow (and this new shroud looks to be significantly more restrictive), or your air flow is blocked by lights and winch ahead of the rad.

[@telecasterfool1773]

That's what I was thinking. Above about 40 mph, I usually have the fans off, even with the air conditioning on. I am not a mechanic or any kind of auto professional. Just a guy who customizes towing vehicles.

[@aussiebloke609]

@@telecasterfool1773 It's the same reason F1 cars don't even have fans - so long as they're not left idling too long, or driving at low speeds, there's no need for a fan at all. So if Yota is overheating while driving, but not while crawling, it's not a fan or rad size problem - which means there's just not enough air being forced through the rad at speed.

[@dustymojave]

Apparently you guys have not watched the entire video or were not paying attention because Paul stated in describing the problem that the engine runs cool when crawling, but gets hot on the road. Exactly the OPPOSITE of what you 3 guys and some other commenters have said.

[@aussiebloke609]

@@dustymojave We know exactly what we're saying. We're considering the possibility that Paul got this one wrong. We know he said he's not overheating when crawling - but that indicates that the fan isn't the problem, as that's when fans are worked the hardest, under high load and low speeds. However, fans are rarely used at all when driving at normal speeds when airflow through the grille becomes much more significant - suggesting that he's maybe blocking too much incoming air with the winch and bumper, or that the shroud may have been too close to the radiator and prevented air from being driven through the entire radiator surface.

MY guess is its not getting enough air due to everything in front of the radiator blocking it from breathing.

This rig spends the majority of its life in the desert at very low speeds, I air flow around the grill is an issue as it would be on a street driven vehicle .

[@Doogle81]

Clear only!!!! I'm so happy that's the plan!!!!

[@Kletke84]

SEATBELTS! Be a good role model. I don’t care if you’re down the street or across the country. Seen too many dead friends cause of no seatbelt

Getting ejected in the bigger problem.

We need to get Grandma in a lot more to help

[@robroten6446]

You're blocking airflow to the area outside of the fan itself. You're blocking about a third of the radiator. You need some airspace. See how the fan was installed in the Crown Vic, with space between it and the radiator, and you'll see what I mean.

[@supersport1986]

I thought the same thing but actually looks like there is about 1/2 or so of air space between the flat of the shroud and the core of the rad so I think it's gonna be pretty good but I guess time will tell

[@Druid_Plow]

That's what the shroud is for. Without the shroud, the fan would pull air from around the gap instead of pulling through the rad fins. Closer is better for a fan that is pulling through a radiator, have seen it tested using computer water cooling. Rad fan is also supplementary. in "ideal" conditions, something like 75° and moving 35+, the rad alone would be enough to keep it cool. But slowly crawling on rocks in the desert is far from ideal 😆

I thought so at first but it is a cross flow radiator so the fan draws from everywhere. There’s a slight dead spot against the sign but the sign will draw heat.

Passed the "Rag Flow Test" in the corners too.

[@Druid_Plow]

@@thejackofalltravels8267 the water flow doesn't change the air flow.

[@edwinschlee8374]

Good job Paul and Ben! Putting that bigger fan on there and modifying everything for it to fit!

[@Bac0n3510]

Still says no views. That's how fast I clicked !!

[@philthy63612345]

Me too

[@2551554]

No I think your phone. Is just slow 😂😂

[@Bac0n3510]

Doubt my s21 ultra is slow. Just damn good

That cutting fat works real good on the sanding discs, and flap discs too.
