I would recommend replacing the Thermostat and gasket thats usually under $20 bucks if you havent done that in a couple years. Mine got stuck in my 93 acura integra one winter when it was in the Teens and driving back from work in traffic of a 72 mile one way trip. Like to froze my Azz off. Whipped in to the nearest auto parts store I could find to have one in stock ,and swapped that cookie out!! Made a nicer ride rest of the way. Took forever to get off the highway to that Auto Parts store

Cold azzed hands too
