Hi Guys, I purchased a 94 Bobcat with a V2203-B Kubota and a fully enclosed cab with heat. I just used it for the first time in the cold. I cant get the temperature up. It only shows 1 bar on the temperature display. All coolant hoses are only warm to touch. I did buy another T stat, but how do I get the coolant out? (sorry for the dumb question, but I didnt see a way without making a mess!!) Also, the 2 lines that run to the heater core are "T"ed into each other. Is the correct? At approximatley 8-10" from the waterpump and Tstat housing the 2 heater core lines join each oher from a T in each line, then continue to the heater core and back. Seems to me the warm coolant might want to take the easiest path back to the motor and bypass the heater core. Any ideas? The lines are warmer up to the Ts and back to the motor than the lines running to the core. Any diagrams of the heater setup? How many bars on the dig readout should the temp read? My whole problem is the air is hardly warm coming from the vents and I keep frosting up all the windows. Thanks for the help!!!
