Hi. I am looking to replace the radiator in my 1983
prevost / 8v92 silver / 754 it has the 871 radiator
in it still would like to recore it or better if i could
find the 8v92 radiator.the price quotes are unreal
looking for thoughts and ideas. have been working
on this conversion for 10 years.labor of love for a old
trucker.and very pleased with the outcome.any help
is appreciated. thanks to this forum for the info.when
i was repowering motor and trans. thanks Jim.
did you disconnect main bus heat exchanger? If so remote mount it and run electric fan to move air across it.
When I turbo'd my 8V-71, I had the radiator recored from the standard 5 row straight fins to 6 row serpentine fins. Improved cooling, but still needed more. Have misters that help out on long pulls in summer.
Misters I started with were 15 from Home Depot. Worked OK, but still had to stop to let cool off on over 100 days. I then drilled out two of the misters with a 1/16th drill. Now they dump some water and it cools down while climbing. I made the radiator as big as I could. Good Luck, TomC
Thanks guys for the comback. Bob I did remove
it as i mounted my gen.set there. Tom were you
able to mount the 6 row in the same framework
as the 5 row? I dont have a bad heat problem
my radiator is the orignal and like me worn down
some. could use some help finding a supplier that
supplys quality at a fair price. or a sound takeout.
the fins on mine are turning to dust. I like the misters
will use your Idea.It only offers to heat on hot day on
the grapevine and dropping a gear and backing out
keeps it in line. thanks tom as you were the one who
advised me to stay with the 92 when I wanted to go
with a b/c 400 I am happy with the 500 hp. silver.
Thanks again Jim.
I have had good luck getting radiators rebuilt for a decent price. thing is you need to find the shop that does this and deal with then directly, anyone between you and shop will double the price.
Usually a heavy-duty copper/brass radiator should take at least a 6 row core. A radiator shop will know for sure. Going to a 7 row starts getting so thick air flow can be a problem. New trucks are using 2 row aluminum radiators with plastic tanks. Course when they go bad you install a new one-no repairing them. Good Luck, TomC
Jim, you've got a lot of good technical advice above, but I'd suggest that (unless you have an acute failure or a critical need to replace the radiator RIGHT NOW) you take your time. If you look around, you might find someone with a radiator or core in their warehouse that's good for the 92 but they've sold off all their 2-stroke buses. Of maybe you can find the perfect rebuilder. Or someone might pop up with an available later-model replacement. It appears that what you have works pretty much OK and you're not going to see "cooking hot" outside temps for another 6 months or so. Take your time and look around.
Built my mister system the second time for my 8-V92 Turobed using 1/2 inch drip mister tubing and 180 degree sprayers really made a difference on my MCI 7
thanks guys. I plan on shopping more what I have found
sofar it is in the ballpark with a new core from prevost.
I do plan on installing the misters I do want to replace it
before I have a real problem.thanks all for the feed back
Jim.
