1949 Chevy Truck, Installing a 180 degree thermostat.

This is part 2 of the swapping of a 160 thermostat to a 180 and replacement of the brand new defective heater hose. When I upgraded the truck to a Deluxe fresh air heater I left the 160 thermostat in. I noticed right off that the new engine rarely made it to 180 degrees even in hot weather and the heat didn't seem as hot so I'm following the original accessories manual instructions and installing a hotter thermostat.
