There are dozens of new threads on heater related problems b/c of lower than normal temps across the USA.Just wanted to tell these folks to check the anti-freeze strenth.If it's not good to -40F or lower you won't have any heat at these temps and wind chills.

 

I see where in some places in the mid-west the wind chills will be -50F tonite,I would run no less than 75% anti-freeze.

 

Also, alot of post on here with hose and radiator leaks and cracks.Probably b/c their system froze somewhere.
