Just wanted to give an update on the heater connections for the Oliver cab that I put on my 1850. I hooked the lower hose on the heater core to a tee up on the bottom of the water neck where the temp. sender was located. The top core hose (return) was I going to hook on the other port on the back of the water neck but there was not enough room there - so I just teed in a hose barb on the existing hydra-power cooler line that goes to that port. I had an air lock and bad radiator cap at first - but replaced the cap and installed a bleeder in the top line at the heater core to get air out. The core now gets hot and I sealed up around the core and roof to get the fan to pull air thru the core. Air gets decently warm. I am guessing the temp gauge needs to get in the middle to get the air really warm. Included a few pics - Alan K had asked for one of the core and there is a pic of the bleeder we made up.
