Days before the first snow I just discovered that the CABIN heater is blowing cold air only, the machine is #7BC01181, this is the early series built in England with a Perkins engine. I've read the 416 heater thread as I am just starting to TS this.
- The pro who installed the engine (I built) also installed a circulation engine heater in-line in one of 2 hoses going from the lower right rear of the block, over the engine to the Cirtc-Heater output, then input, then to the left rad lower hose as one of also 2 hoses connected there to the large rad hose. The Circ-Heater did a meltdown so he gave me another to install, it also started burning out so I pulled it, joined the hose ends with a piece of pipe. All in all the exercise if futility cost me like $400, my hunch is that the routing simply is no good for this type of heater, and that it simply wasn't convecting at all.
- Last winter the CABIN heater was heating OK.
- There is a dual hose leaving the block at the right rear and that fitting looks like an F and has a T-handle valve. The different front left rad lower hose connection also has 2 hoses leaving, no valve there though. I don't think I ever closed or opened this valve, it's pretty inaccessible from the right front engine bay opening as well as from underneath (shame on Cat!)
- Turningthe Temp knob has no effect
- I can't find anything in the manual about the cabin heater, and the hose connections and routing are extremely hard to see.
Tomorrow I'll take some pics and try to get a little more eyes-on.
