On the 4106 not running I'm hoping it's just the shut down flapper deployed by someone not knowing what they were doing. The driver tried starting it with starting fluid. Not a big deal as I was going to suggest they try a little shot of starting fluid to see if it fired and eliminate a few items with that. When I asked him if he tried starting fluid he said "yeah I tried that , I gave it a four second spray of starting fluid and it still didn't start" oh no he ditn't just say that to me...... 4 second spray of starting fluid omg shoot me

I think we have confirmed the shut down flapper is deployed in a video she posted On fb.

I went down to Fort Worth to work on the bus for two days. I pulled the radiator and opened it up. It's a 6 core and it had about 15- 20% blockages internally that I opened up. Then I took it to a steam clean bath. the fins were caked with oil and grease build up. I couldn't see daylight through a good portion of it. I also removed the rear bumper flap to help with cooling, I added a 8 bladed fan, sealed the air gaps around the radiator preventing the warm air from coming back through around the sides, and I changed the v730 from 40wt to tes295. Even if it drops the trans operating temps 5 deg it will help relieve the stress on the buses cooling system. It ran cool all the way to Albuquerque. Lots of little changes that all add up to helping keep it cool. Just an update that it's still going. I'm not exactly sure when they are getting the new bus but it's coming soon. I think this one will hold together a little longer as long as they don't lug it up the mountains and cook it. Good news was the dash gauge was about 10 deg hotter reading than the actual engine temp. It's still a miracle that it didn't get cooked last week when it was spewing coolant and way over heated.

Nasty. So did you actually steam clean it also? Or did you just power wash it? How much power washing can a radiator take before you accidentally blow holes into it? Is it even possible able to blow holes into a radiator with a power washer I was always afraid to power wash my radiators

Is that actually steam, or just a hot water pressure washer. It looks like a pressure washer to me. I spent a good part of a summer running a steam cleaner and it didn't look anything like that.

A pressure washer might okay with a really wide tip and the pressure turned down.

It's a hot water pressure wash. It's a wide fan tip and it never gets too close. It washed away the grease and grime easily. They also coated it with a heated water based degreaser a couple of times and it helped the process. I have pressure washed lots of radiators and never caused one to leak. But they are fragile so always treat them as so.
