Radiator removal 94pt 8v92

[Gregory OConnor]

Dan, There are several was to do it. On the radiators we have in the
bus you will notice a big line of bolts that hold the top tank to
the core (center finns) the shop can remove only one tank and push a
flat strap solid rod in the many journals to open up and clean the
passage. I have this done to my dump truck every 2 to 3 years
($250.00). My bus radiator was so clogged that both tanks needed to
be opened so the tech could push and pull rods from both ends. I
watched the guy cut rod stock from a roll and sharpen it on a wheel
befor he attempted to push the flat stock thru the journal. the
journals close to the sides cake up quicker (frame heat sink) and in
worst case they can be soldered closed and not used.

The trans cooler on my bus is a tank where the trans oil is flowed
over tubes encased in a larger pipe. the tubes (400tubes 12 inches
long) are connected to the radiator ouput. the antifreeze flows thru
the tubes then into the engine. One forum member?? had to replace a
tranny when one of the many tubes in this heat exchanger leaked and
pushed radiator fluid into the tranny. The tech doesnt want to push
a rod thru the tranny exchanger tube because he fears making a weak
spot and having it show up later with water in the tranny. he plans
on using heat and chemicals to clean it and inspect it. the heat
exchanger on my tranny is a BorgWarner and not serevisable. if he
finds issue I will have to buy a new one. ($?,???.??)

here is kinda a diagram of heat exchanger
term ;Tube=Radiator fluid and ;Shell=Trans oil
