Man, some people
Did you go all big spender and get the Aluminum Degas Bottles?
Let us know how it goes!!
I was unaware of any such tank, I expect my wife would appreciate that though!
While I had no issues other than I noticed the thermostat housing was rusty and damp for the few days I practically slept on top of the motor while R&R the turbo, gauge wiring, and HPOP lines/fittings... I think a good flush was overdue. Also glad I came across some threads and good info here on ELC coolant, feel better knowing it doesn’t required the maint. of alternative choices.
These two along with some penetrant made block plugs way easier than I anticipated after the experience I had with the plug when doing the FRx:
Coolant I removed and some of the sediment, guessing some of the SCA dropout:
Thermostat housing and thermostat.
Also replaced lower inlet elbow, new o ring and bolts - only a little rust but figured worth replacing. Cleaned up mating surfaces for it and thermostat housing good
Replaced hoses, glad I saw the one meant for those with dual alt, goes AROUND the serp belt... always wondered what that little c shape was for under the alt.
After running for about 5 min with flush t through heater line and thermostat out, then about 8 with motor running, got clean water. After draining tap water out first distilled flushed looked pretty rough, second not a whole lot better, by the third and fourth I decided it wasn’t that bad and I was not going back to get anymore gal jugs. Here’s the 2nd 3rd and 4th (left to right) flush some I grabbed in jugs when draining:
I figured since cast iron block, maybe surface or flash rust between flushes? I read a post that distilled seems to have a different reaction than tap - either way 4 trips sliding under the truck and getting soaked was my “practical” limit. I got the new thermostat and all back in, and the new Rotella ELC.
Took for couple good drives tested heater and all, topped new degas bottle off and plan to check level over next few days.
