Coolant hoses

[gregory O]

if he blew a hose and it lost coolant the bus would have shut down when the
expansion tank lost its fill and sent the detroit computer in to
crawl-low-r-mode. more to it than just a blown coolant hose.

Does he need a rebuild?

One more test would be to run the bus then screw off the expansion tank sight
window and see if draining coolant prompts a shut down????? this would shut
him down wit a blown hose assuming the expansion tank also loowes coolant as a
result............

a good test to prove that the expansion tank shut down sender proves a shut down
when the coolant hose pops is to run the bus then pop the hose and see what
happens.

BUT........if the t stats are not open, it may be that the expansion tank may
retain fluid. and without hot fluid, the t stats wont open????? in that
instance the expansion tank shut down prompt should then be duplicated to a
block location. where the water should be to cool?????????????

one problem with temp gauges on coolant is they do not measure air temp. if the
coolant is lost, you may not see the temp rise. this is where the oil temp I
guess is your second chance to see the condition. noise is usually a good second
chance indication of a problem but lost chance in a pusher. I am sure someone
will come up with a digital reader to define the sounds reference index then
factor that to ;speed, ;demand, ;rpm ;etc... then take that value and compare it
to good running like noise at the same factor conditions.

I bet sound is one of the first prompt of issues with most mechanical devices. I
even use communication sound changes to avoid breakdowns expensive overhauls in
social issues with Tim.

there that need a wake up call. Birds may be owned but they are a finite entity

owners need to change these hoses. Not just the early models. Every owner of
this engine needs to either replace these hoses or insure that it has been done
previously. 1994/95 was the last year they were installed. That’s old enough.
I can't believe this problem is still occurring and I'm asking all Bluebird
forums to repeat this thread. There is no reason what-so-ever for an engine
failure due to failed compressor hoses. Tomorrow an investigation will begin to
determine if there is any concern regarding the 6V92 compressor coolant hoses.
All forums will be kept in the loop."UNQUOTE
