8v92's Coolant Capacity - 27Gal?

[Hat52MY]

I'm getting ready to change out the coolant in my 8v92TA's. In preparation for this task I have been gathering all the necessary supplies drain buckets, distilled water, Fleet Charge, etc. When I checked my DD Guide it states the 8v92 engine will hold between 24 and 27 gallons each. Can this be correct? Can anyone verify how much an 8V92 System cooling system should hold? Thanks.

 

[JLR]

Mine holds 9 gallons total including the tank.

My Covington 8V92's hold 12 or 14, can't remember which. Maybe that's (27 Gals) for both engines? It does seem like an awful lot. Thx.

I was able to replace coolant in my 8v92TA's this past weekend. I was surprised to see one engine drained 23 gallons - drain cock valves at front engine bottom elbow (13 gal), oil cooler housing (5 gal), Right blower manifold (2.5 gal), Left blower manifold (2.5 gal)....lots of buckets!. Filled back up with every bit of 23 gallons. Is it possible the other posts noted earlier do not have turbos or possibly missing some of the drain cock valves? In any regards, I appreciate everyones input. Best regards./dle.

I'm looking for PowerCool and can only find on Ebay and not sure I trust ebay. I'm a missing a better source for PowerCool?
I have 1989 8V92TAs. I'm leaning toward FleetCharge SCA Precharged at Tractor Supply full strength for $24/gallon.
I'm operating in the Southeast& Gulf so understand Fleetcharge Precharge diluted to 30% is the way to go?
So it looks like I'll need about 14 gals of the FleetCharge for 30% dilution for both engines, correct? I don't want to screw this up. Thx!

Are you up north? 50/50 or to 60/40 (60%water) in the south is all you need.
Order The real Detroit stuff and mix with distilled water for the 92s.
Don't cheap out on what the weak part is on a 92.

A real local Detroit shop can order in what you need.
With a serial number, they can confirm the capacity also.

Power cool also available pre mixed @ 50/50.

Capt Ralph, I understand 92s need their careful cooling.
A prior thread regarding coolant stated must use DD Power Cool with Supplemental Coolant Additives (SCAs) added, and mentioned adding SCA at the ratio of 1 pint SCA for 3-4 gallons of Powercool (I don't recall specific ratio). Your link is for OWI 23519396 which is "Power Cool Extended life" 50/50 without mention of SCAs. Do I need to buy the additive and add SCAs to the coolant in your link?

I do see DD part number 23512138 is DD Power Cool 50/50 with SCAs added but that seems harder to find online these days.

Just did mine and was 15 gallons a side. Used distilled water and power cool additive. No antifreeze necessary in our climate.

Base coolant works well.
Keeping in mind, Other than freeze protection, Coolant and it's chemicals keep rust down, seals and gaskets fresh, cavitation and corrosion down. It is still the water that moves the heat.

The proper coolants to protect the 92s liners and O rings is where maintaining a proper coolant charge with all of its chemicals is beyond just working well.

The correct extended program includes test strips or lab results to guide the original coolants life. SCAs are added (then if needed) to increase certain levels of chemicals as the coolant ages.
Big trucks don't dump coolant every 100K miles (monthly?), they test the coolant and ad what is needed.
Tug boats & serious work boats don't dump their coolant either. It's tested and SCAs added as needed.

With the same attitude, our engine coolants don't require changes but testing and updating its chemical levels can help for years.

Sadly, this is not practiced.
Boaters don't bother with it and replace coolant when its been abused and the coolant is brown.

If there is a real Cat or DDC shop around, ask them for the real coolant theory.

How ever you maintain your engines coolant ritual,, IMO, the factory products should be where to start.

While you are in there.... might want to consider adding a bypass coolant filter. I was amazed at the amount of sludge/sand/rust our coolant filter pulled out the first few times we ran it.
Doesn't matter what coolant you use if there's a ton of gunk in your system. We flushed with freshwater 3 times and new coolant before installing the filter.

FleetCharge is a good product and will work fine in the 8v92. Another alternative is MTU Power Cool Plus 6000 coolant. Its my understanding this is the same as DD Power Cool, just MTU branded (MTU bought DD some years ago - 2000(?)).
It comes down to what is more readily available in the supply chain.

Running 50/50 in in the south is not really necessary, its about heat removal. In my experience you don't need that much freeze protection. Especially, if you have Engine Block Heaters installed. Running in Florida and Bahamas, RPM Diesel recommended 10-20% coolant and the remainder distilled water (9 to 11% by volume per MTU), change ever 3-5 years.

On a side note, there are many boats in Florida that run distilled water and only the SCA. Not my recommendation, but just an interesting note. Personally, having factory Block Heaters installed and running 10-20% of Power Cool / FleetCharge by volume and the remainder distilled water has been a good solution for my 8v92s.

MTU Power Cool Plus 6000 coolant.

Thanks for everyone's advice. This is a great forum!

This is the coolant I use in his recommended by one of the best Detroit diesel mechanics. Got it at Napa auto parts.

 

[Captain Ralph]

Just finishing up some updates to my 12V71TIs. Got my PowerCool in and thought I would post the labels. 40/60 ratio is still good. SCAs already added. Part number on the label front.

 

[Sadey]

Ralph, is that a concentrate?

 

[Captain Ralph]

Ralph, is that a concentrate?

Yes.
You still have to mix with your water to get the ratio you want.

The premix already with water in it @ 50/50 is OWI-23519396.

PowerCool part numbers.

The pre mix usually is 3 to 4 bux cheaper. Purchasing chemical per gallon and then shipping/tax, It's still cheaper to purchase full strength and ad your own water.

Thank you.

Maybe I missed a couple of the petcocks but I was only able to drain about 15 gallons total out of my 8v92ti using the block side drain plugs, the exhaust manifold drain plugs and the front "J" pipe drain plug.
Also I got a lot more coolant to drain out of one side of the block than the other. Do these blocks have coolant passages that share the coolant from side to side or is each side independent of the other ?

 

[Sadey]

How many petcocks did you find?

 

[cenger]

I was told that the Napa Heavy Duty (Pink) was the same as the Detroit Power Cool. I've been using it for years with no issues and its quite a bit cheaper than the DD stuff.
