    I have a 2005 Cat 226. It has factory cab and heat, but the heat is mediocre at best. The hydraulic cooling fan runs all the time, should it? The blower motor works fine, and when its been working you can catch a little bit of heat off the heater, but its only 30 degrees out now. I was hoping for a little better when its 0 degrees!

    Any ideas?

    Your cooling fan probably will not run all the time. I have a 2002 242 Cat, I installed a factory cat heater in it this year. I put a thermometer in the vent and got 110 degree air coming out with the outside temp being about 45 degrees. When I ran it in cooler weather about 25 degrees it would not heat up, I ended up changing out the thermostat and when I test ran it the air coming out of the vents was 140 degrees. I ran it to remove snow tonight, the outside air temp was about 8 degrees, and the heater worked great. So you may have a bad thermostat. Check your temperature at the vent before and after you should get a big difference in them if the thermostat is the problem.

    Thanks Max, Ill try a thermostat first. I was just surprised to see the cooling fan running even right on cold start up. This is my first skid steer, Ive worked on cars for 15 years, but never a skid, especially with hydraulic driven components.
