No heat at idle

I have a 06 f350. I've only owned it for about a week and I'm learning that it was poorly maintained by the previous owner. I'm also new to the diesel community.

So, on to my issue. It was about 30deg outside the other morning (just started getting cool here). I started the truck and let it warm up for a while. When I came out to go to work, it was still cold inside the truck. Temp guage indicated the eng was up to normal operating temp. The heater was blowing out cool air. I messed with the settings, but no change. I dedided to drive it around for a few and as soon as I did, the heater started to blow hot air like it should.

Bottom line, heater works when rpm's are up, not at idle. I know there are other threads about this and I have read them. I wanted to start this one because my issue may be different than others. Today I will take a look at the coolant level and perform a coolant flush.

I will keep everyone updated......

No different. You're coolant level is likely low causing the issue. Probably should get the system checked since previous owner didn't maintain properly.

Possibly head gaskets as well

You're probably going to clog your oil cooler when you flush

It's probably already restricted and caused EGR cooler damage.

The coolant level is a little low. I've found what looks like oil sludge near the coolant cap and filler neck. I drained a little out of the radiator and dark colored liquid drained for a second and then turned into mountain dew colored coolant. So should I flush? Is there a way to prevent the oil cooler from clogging or check to see if it is already?

What's my next step here?

Only way to know if it's restricted is to get a monitor like an Edge Insight or a Scangauge. Need to watch your oil temp and coolant temp while driving 65 mph on flat ground. If there is a difference of 15 or more then the oil cooler is restricted.

I'm going to go ahead and do the flush. I have to drive it for a while before it will be complete. In the mean time, I'm going to see if I can get someone to look it over.

I'm letting the coolant drain now. I also just found a grey vacuum line(?) dangling on the passenger side. Seems like I have read about a grey fitting or line causing issues with the heater. Where would it go?
