Beeping - Check Engine - Stop Engine

September 02, 2021, 11:27:15 am

Coach is making it interesting this morning.

Beeping, Check Engine message. At one point, luckily in front of Walmart, Stop Engine message came up.

Eng Oil PR at 20 psi

Coolant Temperature 203

Engine Oil Tempersture at 200

What to do, what to do?

The Forum tech "experts" will soon respond, but from my experience (different engine) your coolant and oil temps seem kinda high, and oil pressure seems low.

Under what conditions did you see the above reported readings?

Go grab a cup of coffee. Let things cool down some and then check fluid quantities, belts to water pump, hyd pump etc. check connector to ECM for a start..

It was beeping when I aired up this morning at RV park, even after I got to Travel Mode. Check engine light was on but I was 5 minutes past my check out time at RV park. All gages looked fine so I got out knowing Walmart was 1 mile away.

Engine temperature started creeping up and RED Stop Engine came on. Pulled into walmart.

Under those conditions, I would say your temps are too high.

Takes a few miles on the road before our engine even gets to normal operating temp (185).

Did you notice if your engine cooling fans are turning?

I'm sitting at a safe spot out of the way in the Walmart parking lot. It is pouring rain in sunny Florida right now. Radar has rain ending at around 1 pm. I'll let the rains pass and also let the engine cool down before I get fo the engine.

If I do need antifreeze, what kind is recommended for this boat? Would Wallmart tyically carry it?

I have pulled the manuals out for some relaxing read.

Your year coach would have ELC in it unless changed out by a PO. Final Charge is usually found at Walmart's and would be what to use. 20 psi oil pressure at idle is ok for an ISM. 203 water temp would be ok climbing a grade oil temp the same. Those numbers don't set off any alarms or red circles in my VSMpc

The engine temperature gage was climbing into a range I have never seen before. Even when climbing hills and at high speeds. Very unusual temps after just getting on the road. I guess coolant levels and belts would be the first thing to check.

You do not have any belts in your cooling system, all gear driven including the hyd. pump for the motors. Remember the plastic reservoir is not the tank that circulates the coolant, just a extra tank.

Peter said he started engine and drove 1 mile to Walmart where he is parked.

Coolant level in the metal tank has a sensor on his coach.

I think that was it.

There was no coolant in there. I have already poured 4 gallons of SupeTech OAT from wallmart and it will take more. The white overflow tank is empty.

How many gallons to fill from empty?

I'm going in for more juice

This is where the VMSpc comes in handy. You can see what the code is and know exactly what to look for. 2004 U320...I'm guessing ISM? If so, I hope that SuperTech stuff meets Cummins criteria. It's kinda specific. Sounds like you've found one issue (coolant). Hopefully that solves your beeping and issues.

The next and more important question is "Why are you 4+ gal low?"

If it's an ISM450 I believe it takes about 16 gallons, but it doesn't mean you need that much to fill.
Did you notice any coolant under the coach?
When was the last time you saw coolant in the over flow tank.

You need to change the coolant when you get home. That Super Tech isn't for Cummins engines.

Beeping gone. 7 gallons to fill black tank. And I still have not put in any into white overflow tank because I need an appropriate funnel to get into that tight corner.

I'm an idiot, obviously. The moral of this story is to have a ckeck list. Better to not be an idiot to begin with. I'm good at checking tire pressures, and engine oils. Had not checked coolant. Why you ask? That's what happens when you leave on a trip in a hurry.

Because of rain, it is hard to check for any leaks now, but I need to do so ASAP.

SupedTech is OAT. But, not good for Cummins?

Everyone, thanks for all your help. A special thanks and a boy scout badge goes to Rudy for his telephone call.

Let this be a learning experience for all. It was certainly for me. I was extremely lucky to be at the entrace to walmart when the Stop Engine warning came up.

It is also good that I'm a member of the very ancient Stoic/Stoicism club. Because when you own a bus, you learn to go with the flow.

In addition it is also very fortunate that I have a reservation at the World of Beer place in Ft. Myers FL, a Harvest Host site. After this, I need a drink.

Peter,

With that substantial a leak, you need to find the source before driving.

Be sure to check engine oil and transmission oil for signs of coolant contamination. If found, do not even start the engine!

Not going anywhere.

I just found the leak. A bad one. If I can't get to it myself, it will be time to call a mobile tech

That size leak should be very easy to find!

Your 2004 came OEM with Shell Rotella ELC extended life coolant. Mixing coolants can cause issues.

Flush out, change filter, find proper ELC coolant. Readily available at Tractor Supply in the concentrate (best value, mix with distilled water) and pre-diluted 50:50 flavors.

Oil and trans fluid look normal?

See where the leak is coming from if the oil/trans fluid looks good?

Once you get to where you just need to fill the overflow tank, I use a solo cup. You can squeeze it slightly to make it fit into the space. Slow but you usually don't need but 1-4 cups.
