My dealer installs lower rad heaters standard and did so on both my CK30 and DK45 cab. It's a little tight in there, but it fits exactly where you described on the DK.

Can you get a picture of how they installed it so I can compare to the factory layout?

No problem, I'll try and get it for you tomorrow. It's a really busy day, so don't feel bad reminding me tomorrow night if I don't post a pic by then.

Here's what I have.

I see what they did, and it's what I was thinking about too.

The cab heater return line is normally placed (at least on my tractor) where the heater is located on yours. By placing the heater where the return is normally placed they were able to l mount it on an angle. Clearly your tractor had enough slack in the heater hose to move it a couple inches down, hopefully mine has enough slack too.

Well, every tractor they sell has the same set up, I didn't ask to have it installed for either tractor I've bought from them, so I'd assume they all should have enough slack. Good luck.

I checked my tractor last night and it should be possible to get enough slack to relocate the return port a couple inches further away.

My next question is has anyone ever drained the cooling system on a cab tractor? I'm concerned that if I drain the system will the heat exchanger in the cab also drain and will I have to deal with an air lock.

I suspect there must be a check valve in the system somewhere otherwise wouldn't the coolant flow out of the rad when you take the cap off?

I was thinking I would pinch both of the heater hoses before draining just to be sure.
