Subject: [WanderlodgeForum] Radiator removal 94pt 8v92

David,rad removal '94pt-8V92. I removed the panel below the louvered
door by drilling out 2 rivets and removing screws. Kept the fan oil
radiator and aircon setup attached and moved both out of the way.
dropped about 20 gallons of antifreeze. slid rad out 6 inches to
clear fan as the fans shroud remains attached. lowered forklift
about 8 inches then walked the entire radiator out across the
forks.

There are a row of sheetmetal screws that hold top rubber lipped air
foil to the body(4pieces direct air into rad). I was able to remove
only 3 of the 8? as you only have access to the back of the last
screws . I loosened them with vice grips after stripping the thread
with an airfile; then cut the screw off. I plan on tack welding a
nut on the back side of the sheetmetal panel to reattach.

Took full two hours, one man
filled 4units of 5gallon pails with antifreeze
I would guess rad weighs 120 to 175 lbs???

day prior I set the frame of the bus on blocks and sprayed all hose
clamps, screws, nuts and bolts with liquid wrench. crusty bolts
were coated with a finger full of greese.

gotta watch fan, will reinstall with signboard strips taped in a
pannel between fan and rad. simple 2x4 skid platform with jack inder
installed radiator end would work better than forklift. forklift has
no way to offset forward slope of jacked bus (will reinstall with
2x4's). fear I tweeked the drain pitcock when the weight rested on
it as I lowered it in my pickup. I will post the rod cost or shop
recomendaton.

You gain little additional access to hard to reach aircompressor
cooling lines with rad removed.

Greg, tell me if I am wrong but I don’t

think radiator shops actually “rod” the radiator. I think it is

all done with chemicals now.

Radiator ROD is what it is...push a rod through each tube, and flow/pressure test after. Anyone doing less is taking your money.

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

I paid $3800 last summer for the re-core up here. Makes me feel bad reading your post Greg. Oh well, just money.
