The Coolant tank has both a side and top inlet so it can be installed either in a short and wide application, or a tall and narrow installation. This allows 1 part to be more flexible with multiple vehicles and uses that have size restraints. Very common in a commercial type vehicle. It is left hand thread BECAUSE it has multiple caps. They do this just incase you go to standard loosen a cap, which tightens. This avoids accidental spills, and lets you know to look for a 2nd, or possibly 3rd tank cap.

[@flipfloptanlines926]

True, and probably will last. But if its not your vehicle, and you are a professional shop, YOU MUST WARRANTY all repairs. Replacing the assembly is a warranty issue. Way less likely the truck will have a "Comeback" that will have to be repaired for free, and an upset customer. Especially since a new tank assembly is a generally low cost item with minimal labor. Labor is the biggest cost, even with expensive parts.

[@valeriedunbar9227]

Hey Ray! The second cap on the side of the reservoir opens a bleeder if I recall correctly so that you can properly refill the reservoir. They are compartmented and the lower reservoir is to be refilled as well when servicing which entails plugging the overflow and filling the top tank up so that coolant goes through the 2nd passage by the cap down to the lower tank. After a while it stops taking coolant in that way, and as such specialized tools are needed to force more coolant down to fill it fully, although you can rig up a tool out of spare parts to do this. This comes from what I can remember in my time replacing block heaters under recall as a GM tech on these trucks, and in the notes it was as well mentioned to be critical that this lower tank be filled and to level. I would pull up the documents to double check, but as I am no longer a GM tech I don't have access to PBS anymore. Hope this helps!

[@valeriedunbar9227]

​@@richardwernst they're compartmentalized, I believe the lower section is the pressurized section of the tank and the upper section is just a reservoir. There needs to be appropriate coolant levels between the two of them for proper system function. It's similar to the older style reservoirs for the Duramaxs that are side by side, only real difference is that the newer style is one on top of the other instead.

[@stevewhiting556]

The engine itself probably is. It’s the 4,674 different sensors, coolers, heaters, valves, pumps, solenoids, etc. that make the problems. Diesel fuel is harsh for the environment when burned. It has to be at the right temperature, viscosity, and then needs to be catalyzed for it to score low emissions. These trucks also make twice the power and torque than they did 20 years ago. I bet if you put a 25 year old fuel and exhaust system on one of these new motors, they’d never break. They’d make 1/2 the power and blow smoke, but they’d be damn near bulletproof. Emissions are why the 7.3 died. It was cheaper for Navistar to engineer a new engine than keep throwing crap on the old one to meet the new standards. Plus, all the new redesigns have made these things vastly quieter.

@@GarryFishermusic I mean, the dealer is the one stuck with these parts. Try explaining to a Mitsubishi Mirage Customer that you quoted their one 14" hubcap at $127, but the lowest you can go is $92... because that is the COST. I understand the dealer is selling the part, but they actually have pretty minimal control over the cost on the OEM stuff or repair procedures. Which is why every Outlander with a blown trans cooler gets literally whatever size the parts store has in stock, lines spliced, and tack welded to the frame. $180 vs $1600 for the part, and 20 minute repair versus.... I can't even remember book time to re and re the factory cooler. It's... a nightmare.

I’ve seen you do this a couple of times now. You mix “red” and “green” antifreeze. When “red” first came out they could not be mixed as it would gel and kill the engine and radiator. When did that change?

[@helmonful]

Red is propylene glycol and green is ethylene glycol, using the wrong coolant in the engine can degrade seals and in some cases even damage the engine block as the additives differ between the two. the red dexcool type has additives to protect aluminum blocks and heads the green stuff usually doesn't. But hey gotta keep those customers coming in.

Sure. But where it matters, countries like India, China, and your other large industrial polluters, they couldn't care less. They will continue to undermine the efforts of other first world countries. And I'm not one of those tree hugging types that gets super riled up, just saying. Diesel pollution I don't think was ever that bad to begin with. Ok sure, it did help produce a lot of the smog in large cities that people used to be so fond of, but not much of the ozone depleting variety. Look at what Joe Biden/large government has done to energy prices in the U.S. IT's shameful, it should be. Modern coal fired power plants put almost zero emissions into the air. Their stacks emit water vapor and a small bit of carbon dioxide, or plant air as I like to call it. Or with your nuclear plants, well I'm no expert, but I think they don't put out anything but some water vapor. Anyhow, my rant is over.
