Extreme cold impact on hydraulics

    Own a 2005 Jeep wrangler with an old beat up 6' Western on it. Drove fine yesterday, but when I went to start it this morning...nothing.

    Granted it's dang cold out there (-20 to -50 overnight), but the dash lights came on, and the hydraulic power light for the plow also lit up. Got kind of a nasty rattle that did not sound like the alternator though.

    Wondering if the cold had an impact on the hydraulics, but even so, why would that impact the ability of the vehicle to start? Garage won't accommodate a 3rd vehicle so this had to sit outside overnight...

    Would jump starting it work? I thought about taking a hair dryer outside and heating some key spots, but am not even sure where to be honest...

    Get some heat on that engine. Those negative temps will keep it from starting.

    What kind of oil are you running in the jeep?

    I wanna say Synthetic 5W30, but would have to check - also have been wondering if an engine block heater would do the trick? Those are only like $40-$50 to install, but it'd be tough to get done right now because the plow is down and I have no way to raise it without starting the jeep in the first place! LOL

    Cold impacting hydros and batteries and now a truck won't start. Never heard of this before sounds odd

    Yes. This is common, common sense!

    Not sure if you're being serious or sarcastic. I know it's the cold, just more a question of what is impacted and how to fix it. if it's the battery, a simple jump start should suffice, correct?

    How would I alleviate the problem if it's the hydraulics that are frozen though? (Sorry if this sounds rookie, but I am not a serious plow business, just my own driveway and a few neighbors and never dealt with this kinda cold before...)

    It's in the negative temps and your asking what is effected and how to fix? Really. C'mon man. Batts don't like cold. Hydros don't like cold.

    Put in a block heater

    Even put a 100 watt light bulb under the hood in the right spot and it will make a difference.

    You might be able to place a heating pad under the oil pan and used bailing wiring to hold it place to get you going. I'd also suggest you through a moving blanket or tarp over the top engine to hold the heat in.
    Also get a KATS inline block heater, they're easy to install and relatively cheap, I've used both styles shown below and they both work very well.

    I understand that cold affects everything (even my arthritis is reacting to it! LOL). However, I am not a mechanic and thus was asking if anyone could get me started in what the best course of action would be to try and get it running again.

    Thanks for your "help" though...

    Get some heat on the engine. It will start eventually

    That is the best advice and I thought THAT was common sense. Heat.

    Heat the engine and after a while I would try it. If does not start then try putting a battery charger on it and see if that helps.

    You could also take battery out and put in house until warm. Then after installing back in truck it should have lots more power to crank.
