Hydraulic jacks
We have read that the leveling jack fluid can freeze. How do most MH owners prevent this or is my question incredibly stupid? We would like to use our Mh in the winter, but dont want to damage our machine.

- Antifreeze for jacks? I love this forum
- Don't tell CW about this. Way they solve problems nobody has, they'll introduce Hydraulic Jack Antifreeze.
- Reko u r exactly right, I miss Read this article, and I appreciate the feedback,
- Thank you Doug, Puts our minds at ease! And your right, hasn't been an ice age in a while.
- Might be confused with sometimes the jacks will freeze to the ground. If the jacks get any kind of moisture under the jack pads, the springs will not have enough force to pull the jacks back up if they are set down on asphalt or concrete. If on dirt it will also sometimes not release but will usually bring up a mess of earth if it does. I used hot water to get me unstuck once but if I suspect freezing weather I now usually put a block of wood under the jack pad and since the water will soak into the wood and not build up around the pad as bad it will usually release the jack and after I pull away I can go back and beat the block with a hammer and it will usually break free as well. I've also sprayed WD-40 on the bottom and usually had luck with that also.
- WHERE have you read that? The fluid is the same as in your Car Transmission. So, when have you heard of a Car Transmission fluid freezing? You are OK, it will not freeze. The freezing point of Transmission fluid is -65 degrees. So, I know of no area in the USA where people camp and use motorhomes/trailers that get that cold. Doug
PS, IF you got water or moisture contamination in the Jack fluid, THAT liquid would freeze. But, it would take a lot of water contamination to harm the system.
