Reading that thread about the heater core got me to thinking about my heater. How warm should the air coming out of the heater be? Right now I have the stock fresh air heater and i bypassed the control valve (it leaked of course) so i have the hoses connected no valve nothing. My truck runs at a constant 180 to a 190 degrees. Me and my wife took it for a cruise last night the outside temp was 54 degrees and the truck warmed up to the 180 to 185 degree mark but the air coming out of the heater felt like 60 degree air.

I went under the hood and both hoses were warm. Now I think that it should be warmer than that. Maybe I'm wrong but some insight would be appreciated also just incase it comes up i have the hoses connected according to the manual minus the ranco valve of course. Please help I'm looking forward to a toasty ride. Also I'm sorry for my grammar and spelling mistakes I was working all day and I'm so dang tired I'm Seeing two screens right now. lol.
