Winch cause overheating?

A winch is on my mod list but in looking at mounts and options it appears that a winch will block at least 1/3 of the radiator surface area. It seems that in 100+ temps blocking the airflow is a bad idea. Anyone with a winch had any cooling issues or concerns?

I saw this question come up and I don't recall anyone having any real issues with overheating, however if you would rather be sure not to cause a problem one solution is to get an off-road bumper where the winch is recessed. Lots of them have a recessed design (Lod, AEV, Mopar).

I havent seen any JK's have overheating isues with a winch. Mine has been in the woods with no wind at all geting to the jeep going very slow for a few hours with the AC on and I havent had any problems at all on 100+ days. My jeep with the winch handels the high temps better then my 2001 chevy 1/2 ton ever thought of, and my truck dosent have a winch on it.

The winch itself is usually fine. People run into issues using large vinyl/canvas covers that can flip up at speed and cover more of the grill.

Ah never even thought about that, but then again I dont know anyone who runs a cover on a winch. The are kinda pointless to me. If you are scared of your winch geting wet or muddy maby you should have bought a better winch? IDK maby some folks run them for looks? Or I guess maby you might need one if ice is an issue during the winter?

My winch sits down inside the bumper and doesn't block even a 1/4 of the grill. Mine has a cover, just to keep the sun off of the synthetic line, it is brutal here in the SW.

+1

I bought a cover for the same reason. I wanted to keep my synthetic line from degrading over time due to sun exposure.

Thanks for the replys, seems a non-issue...I worry too much having a couple old Chevys that run hot for little or no reason. I will continue my winch hunt with wreckless abandon.

I have had overheating issues ever since I installed my winch. I've overhauled my cooling system but I still get hot at slow speeds. I'm not sure its my winch but I've replaced everything from my fan to my water pump. My winch mounts on top of mybumper and covers most of my grill

I would think the contrary, the more I spend the more I would want it protected. Snow, rain, hail, rocks kicked up, the trail of sand constantly following a semi, bird sheet, birds, insects-i trout fish-ever drive by a river when a hatch is going on? They can show up on radar. The elements shape rock. Why wouldn't you cover it? $15-20 at tsc.

Never had mine come off at all, elastic bottom. No overheating issues but mine is fairly well recessed. Put 4" auxiliary lights on top of bull bar, still no issues.

Have you tried removing the winch to see what happens?

If the winch does turn out to be causing yoh to overheat, then could something like a hood louver help solve this problem? I know the air would not be send through the fins of the radiator, but I wasnt sure if it could still help.

While it makes sense as to why it could cause over heatting, I dont feel like it should. My biggest thing would be that you have some of the top brands, I.e. PSC who sells front bumpers with winch mounts, but dont have the winch dropoed down into the bumper. In fact, I dont feel like Terri make one that drops in at all. I just feel that if this were a true problem, then the engineers of these major companies would have located the problem and found a solution by now

A winch wouldnt be a problem at all.

If it were, the hundreds of thousands of jeeps with winches would have lead to thousands of posts about it being an issue.

My jeep spends 99% of its life below 10mph with a winch in front of the grill, never had a problem.

You could put a 4'x4' piece of plywood on your bumper and drive 80mph, as long as the fan could draw around it you would be fine.

Tweak (above) has the right idea. Here's the deal, folks. Modern radiators don't require any kind of "ram air action" in order to cool. As long as you don't actually seal the rad, the fans can suck the air around your winch just fine. Think about it -- any car (think taxi or cop car) can sit for hours upon hours at idle, then run at speed for a few minutes and heat up, then come to idle again and just sit there, hot and panting, but they don't overheat. The fans suck the air if you're not ramming it in by being at speed.

If you had a big enough winch, and it was close enough back to the front of the opening, then I'd say you might wind up with fans that run more than they would without a winch because the rad wasn't getting enough natural airflow at speed. They'd still draw enough air for your motor, but they'd run some of the time that they wouldn't have normally because of the natural cooling you get at speed.

But again, this would require a much greater blockage than anything a standard winch provides IMO.

This.
Our grill opening is largely cosmetic.

This was my setup prior to getting an aftermarket bumper. I checked through the dash readouts the before and after install. 1 was a loop through town (stop and go) and then a 30 mile highway trip. There was no noticeable temp change before and after the install

Ive never had an overheating problem with my two Jeeps. On my TJ, the winch was mounted on top of the bumper. On my JK, its recessed into the Warn bumper. Never an issue even with Ohio's hot and humid summers. On my old Warn XD9000i I never had a cover. That was back 15+ yrs ago so my line was steel cable. A few times in the winter though I remember having some ice build up. That, and daily driving here took its toll with the salt. On my new M8000s I keep it covered. One, because Ive grown up a little and I take better care of things now than I did when I was in my early 20's and late teens, and two, because of the synthetic line.
