RE: Air Filter Restriction Indicator?
Correct.
It "remembers"/stores the max air restriction since last reset.
So long, high RPM full throttle applications show the stored max restriction.

RE: Air intake systems on DP cummins
Does anyone ever replace that $5 gage instead of spending Big $...
If you have a reason to suspect the air filter minder is inaccurate, sure replace it.
But a simple test is all I do once a year (unless it flunks the test).
Pull the line to it. Start sucking on the line (sure, wipe it off if you must, but a little dirt probably won't hurt). As you gradually increase "vacuum" you should peg the gauge. And when you stop, it should stay at that max reading. Pushing the button on the bottom should release the reading back to 0.
They are pretty simple mechanically.

RE: Coolant Test Strips
Not to add any confusion, but...........
It sounds like you are a new owner of this DP.?
Would you not be better off to drain/flush and install a new thermostat and then add ES Complete with distilled water and blank filter??? That would solve the problem! JMHO.
I agree. Changing coolant is MUCH less expensive than taking a chance on engine, radiator or other cooling system failure. And using an OAT-based coolant will give you 6 years peace of mind with very little effort (usually just an extender half way through).

RE: Fuel Separator Replace, Need advice
A frequent cause of this is that the level of fuel in the tank is lower than the filter housing. When you remove the filter with the fuel level lower in the tank, the fuel can siphon out of the line all the way back to the tank.
So, changing the filter with full fuel and/or front of coach higher than back help minimize this.

RE: Coolant Test Strips
This IS a confusing subject for those new to the diesel coolant world.
PLEASE, VERIFY, repeat VERIFY what coolant you have in your coach's system.
If a "low silicate coolant for diesels with added SCA" (the standard coolant used by most chassis makers) you DO test for and add SCA's. Do not just add-- test with the strips first, as too much is as bad as too little. As said, SCA's are sacrificial and are used up in the normal process of driving-- therefore they need to be replenished.
BUT (read that a BIG BUT) if you have an OAT-based coolant, you do NOT add or test for SCA's. Most OAT-based coolants do call for adding an extended after 3 years or so.
So, please verify what you have-- treating an OAT-based coolant like "regular" coolant will not work. And treating "regular" coolant like an OAT-based coolant will not work.

RE: Filter Change Allison
If changing filters AND fluid, most of a 5 gallon pail-- so buy the pail, it is less than buying by the gallon.
You will need an inch-lb torque wrench to properly torque the filter cap bolts. Don't over-torque-- they are screwed into the aluminum case.

RE: Water pump not pumping
Open faucets, turn it on and let it run. The less restriction on the pressure side when trying to self-prime, the easier and faster it is.

RE: Water pump not pumping
Have you sucked on line from the tank at the pump to verify that there is no line restriction?
Make sure there are no air leaks on the tank to pump side (vacuum side). If bayonet fitting filter, make sure it is not allowing air into the pump.
Open a faucet when you turn it on and it will self-bleed to a reasonable extent.
All this assumes the pump is mechanically working.
Telling us what pump you have would also be helpful.

RE: Air intake systems on DP cummins
The air filter minder reads TOTAL air system restriction, so any/all of these can add to restriction:
1. Too small an intake on coach side.
2. Convoluted routing from side of coach to filter. Each turn adds to restriction. Corrugated hose is more restricting than smooth-wall hose/PVC.
3. Too small a filter (too little surface area). The larger the filter (that will fit your available mounting area) the better.
4. Convoluted routing from filter to filter minder pickup tube location (and effectively all the way to the turbo).
I suspect your Banks kit added boost, therefore the original filter AND hoses may be too small for your new CFM needs.
Mantra: You can't feed a diesel too much air.

RE: Sucking dust
OK, if you are not very skilled at it, you don't want to blow out a paper air filter element.
And you do not want to bang one on the ground and reuse it.
It is way too easy to break a pleat in the paper element which can allow dirt directly into the engine. That is known as "dusting" and can ruin any engine in short order.

RE: Power Steering Fluid
Best answer is to look it up in your book or call Monaco.
Motor oil, ATF, and hydraulic fluid are each used-- you need to find out what is in YOURS.

RE: Sufficient Diesel pucher HP ?
For a real in-depth discussion of RV performance, go to this Caterpillar document-- it applies to all heavy vehicles-- gas and diesel. After all, physics is physics.

RE: Sufficient Diesel pucher HP ?
Actually, both HP and torque are important.
What a diesel does very well is produce high torque at low RPM's. For example, the engine mentioned by the OP is only 7.2 liter (Caterpillar), but produces 860 Lb-Ft of torque at 1,440 RPM. Multiply that times RPM's to give HP and you still have reasonable HP at reasonable/sustainable RPM.
By reasonable/sustainable RPM's, I mean an RPM that the engine can sustain for long periods of time. THAT is the difference between diesels and gas engines. Though HP's can be similar, the RPM needed to produce that HP in a gas engine are higher than one would want to use for very long (like up the Grapevine or other long pull).
So, a gas engine could produce the same HP as a diesel engine, and both could pull a grade at the same speed, but the gas engine might be turning, say 4500 RPM while the diesel engine would be turning only 1800 RPM. BIG difference.
This is NOT a recommendation for diesel/against gas, but merely a clarification of the major difference in how they are operated in an RV.
We just pulled into Albuquerque on I 40. Our little Caterpillar 3116 (402 CID) never saw the upside of 1900 RPM on any of the mountain grades. Sure, gas coaches could keep up with us, but they WOULD be wound up on some of those grades.

And that Cat 3126 330 HP and torque (860 Lb-Ft at 1,440 RPM) will have its full power available (due to turbo) at those elevations-- in fact up to 10,000 feet. VERY important.
