Update - Thermostat and radiator service, with 6,000 pound in tow.

[Curt Sprenger]

Update...The past few days I ran the bus about 400 miles, 6,000 pounds
in tow, outside temperature in the 80's. On the flat the coolant
temperature run 180-185, oil temperature 220. Climbing Whitewater Grade
out of Palm Springs, 40 mph head wind, the coolant temperature got up to
190 degrees, oil just over 230. I'd say changing the thermostats and
clean/rodding the radiator was a good thing to do.

Sounds like you did the right thing replacing all of those parts.
That's what I did on mine too. Plus new water pump & new rad core
(increased cooling capacity 15%). When it warms up some, will take it
out on I90 to see what it runs at now.

Terry,
Please keep us posted.
How many miles on your engine?

Curt, it has 171,000 on it which appears pretty close from the Hobbs
hour meter. Went through all the upper part of the engine. Rebuilt or
replaced the blower, turbo, water pump, fuel pump, Charge air cooler,
etc. Resetting the fuel rails now & putting it all back together.

Terry,
I wonder if a correlation could be established between engine miles and
the coolant/fuel hose, pump, maintenance requirements. Would be useful
to other 'Bird owners for sure.

You are doing a lot of work on your engine. What is the rational for the
blower and turbo work? Do you have the maintenance history on your coach?

You must have a shop to park your bus and work on it.

I doubt there is any correlation between maintenance on an engine
used in RV service on one coach relative to any other coach and/or on
an RV engine versus one used in over the road class 8 truck service.
After talking to diesel mechanics, coach owners and truck owners
there appears to be a vast difference in the way the engines are
regularly driven and serviced which I believe is the main reason so
many of our engines are overhauled or replaced at such low mileages.
From what I have seen it is not unusual for our coaches to sit for
months at a time between uses which is not good.

If you look over the various internet sites where RVs are sold it is
not unusual to see engines replaced long before the average service
life of the engines detailed in the manufacturers manuals.

The same appears to be consistent with transmissions, radiators etc.
Two things you can do to minimize the problems with your coach, first
use it as much as possible, and/or start it up and drive it a few
miles at least once a month EXCEPT if it is stored for the winter.
Secondly do the regularly scheduled maintenance, including filters,
air dryers etc and dont over stress the engine by lugging it.

Curt Smart move with addressing your cooling system on your 92. I learned years
ago, that you just can't overheat a two stroke Detroit, you may luck out and do
it once, but you'll never get away with it, twice. What you did was the cheapest
insurance, one can buy. Good luck! Jimmy Harvie

Terry, I'd say change your hoses every other year, If you drive it or not. Also
don't be afraid to use a nutdriver and go over your hose clamps often. Those
Detriots vibrate a lot so I used to throw a wrench on all of the engine bolts,
on the ones I used to own, expecially the oil cooler. I use Permetex #2 non
hardening goo goo on all of my connections. One thing to remember is always put
it on the male end, so none gets inside Good luck!

Jimmy:

I think your recommendation to change coolant hoses every two
years is a bit of overkill. I am running my hoses now in excess of 6
years with absolutely no problems. I inspect the hoses regularly and
do check clamps on a regular basis.

Terry, I have missed some posts here. What happened that you had to go into a
DD6V92TA with only 171000 miles. Those engines are barely broken in at that
point. I have not known of many failing with what would be considered low milage
for that engine. On my part, since joining this forum in Dec., I have been more
alarmed at the failure rate of the Cats, at fairly low milage. Good luck with
the repairs, George Burke, 1977FC31 Charlotte
