Installing The New Warn Endurance 12.0 - Endurance Winching

Posted in How To on April 1, 2009

We don't know what your girlfriend or wife calls you, but we can guarantee your friends will refer to you as Mr. Endurance if you get yourself one of these new Warn 12,000-pound winches. What makes them so great and why? Well, the new Endurance 12.0 has an innovative cooling system attached to the housing so it can handle a continuous pull (or even multiple pulls) at full load without burning up the winch's 4.6hp motor. And in case you weren't already aware, continuous heavy-duty pulling can burn up a winch motor very quickly. This is why you will see many winchers take a break about half way through the winching job in order to let the winch cool down.

Heat is the No. 1 killer of winches, and Warn has found a way to directly combat this overheating issue and allow for a safer, longer pull of whatever you're winching.

We got to try one out on the front of a hefty JK Wrangler adorned with 40-inch Toyo tires and a bunch of other heavy parts.

How Did It Pull?
We brought a temperature gun with us to do the winch testing, and checked the temperature after a full pull. Warn is not specific in how much you can pull before the motor gets too hot, for obvious liability reasons: Warn does not know how heavy the load is on the cable or at what angle you are winching with the Endurance 12.0, so giving an exact number of how far you can safely pull is just not possible.We can tell you we did a full pull, and then immediately let the line completely out again (under the same load). We have been told that winches will actually heat up more quickly under load when letting line out than when winching it back in.It was 48 degrees F out that day, and that was the exact reading from the winch housing, according to the temperature gun, before we started winching. After a full pull in and out, we never got the housing around the motor over 132 degrees F, but something to note (when the line was completely spooled out) was that the temperature of the winch spool was 188 degrees F.
