We have a nice little stream of coolant leaking from the curbside radiator. I guess I'll be searching the forum for a source to buy a new one recore this one. Is there an R&R instruction thread for replacing the radiator on an MCI 9?

Good write-up, Gumpy. Well described and the photos are clear. Cleaning, fixing and straightening is a big part of all this, isn't it? Those two big blowers up above your engine -- do they draw air through the radiators? A centrifugal blower like that is always going to move air better than a bladed fan but they're sure big, and, by your account, heavy as anvils! Where does the air exit from them? It looks like they shoot straight down onto the engine but that wouldn't make much sense (sorry, I don't have any experience with an MC9). Everything still working well?
Thanks, Bruce H NC USA
Hi All, MCIs from the 5s on air is sucked in thru the split radiators at window level, pushes air thru fan department to engine compartment, and is sucked out the bottom and onto the roadbed, this is the reason mud flaps have to be (infront of the engine and) just behind the wheels not across the entire rear, mounted to the bumper, this is not for models where the single radiator is mounted in other places, lvmci...
When I repaired both my radiators, I made sure to replace the rubber seal around each unit. That really made a huge difference on "sucking" efficiency!

Thanks gumpy!!!! :)

If you can't find anyone else give these guys a call. I know that they handled MCI radiators a few yeas back.

Im a little off the beaten path , if you need mc9 radiators i have several in good condition .
just replaced both my radiator cores , 1992 mci 102d 6v92 , got them from general radiator industries , 1380.00 plus shipping . not a terrible job if you do it yourself , took a few nights ,
Get some gas tank epoxy repair for a couple of bucks, push it in the leak, and keep on busing!
I'm going the repair or replace route. Took me a couple of hours but I finally yanked the old one out. What a pain. Anyway, hoping the other one doesn't spring a leak on me for at least a couple of months.

Good Job Scott. Should do them both at the same time ;)
I would if the budget allowed but one good rad will get us going :)

I also documented the process:

Mike that's great work you and your son did, I also followed your other bus build articles good work and thanks.
Jim I checked out your site, with the write up on the repair that's a great. And the some cool paint to Thanks
Thanks guys, glad you enjoyed them.
Wagwar: Thats a great write up, I will have to remove the blowers eventually. I suspect once we start driving the bus we will also have dried up seals to deal with. Its been sitting for 4 years now as I convert it. My wife is to the point where she just wants it usable so we can enjoy it.
Nice!! Thanks for posting these! :)

Just got a quote from a well known and well liked radiator place in Michigan. $1900 to recore my 1 mci9 radiator. Someone please tell me that price is wrong...
I have a call into general radiator. They were nice but their website is a little scary.
http://www.generalradiator.com
That is a bargain compared to the on that resides in the back of huggy.
Still have heating problems.
That's the problem with making horsepower out of a 2stroke Detroit.

Scott; check local bus companies --Might be surprised what they have laying around they don't use any longer. The MCI's with 2 rad were work horses for along time for many..
FYI I'm not hearing good things about general radiator. Not impressed with my interaction with him today.
try diesel radiator in Melrose Park I'll. it's been a few years but the treated me real good
Try these 2 I bet one will have what you need for 1/2 the 1900 bucks
Daniel Radiator 1-800-767-0395
Hart Radiator 1-713-675-6313
both are in Houston and do a bunch of bus radiators
good luck
those seem to be a lot like the Radiators I have in my MC5 A ?
About the same, just a bit bigger. One common modification if you put more power in an MC-5 is to install MC-9 radiators.
Brian
Scott - This drives me crazy! Don't be afraid to go looking around in old junk yards and weld up a frame to make it fit. As long as what you are putting in is bigger than what you took out. I pray this doesn't set you all back another month. That's not healthy for a herd of turtles.
Loving the brotherly love Sean. It's just life in a bus :-/ cliff, the guy quoting $1900 said the mci9 radiator has a ton of cooling per square inch. So he cautioned against getting anything with less cooling power, I concurred seeing that 6v92s don't take kindly to overheating. General radiator claims that he can use 1/2 tubing instead of 3/4 inch and get by. That scares me.
I bought my 2 radiator cores from general radiator & was skeptical initialy when they said their cores were much thinner , the guy i spoke to said his cores would cool a battleship so i ordered them , well after i receieved them & saw much less cores / tubes i called them & was again reassured they would be fine , I then procceded removing rads & recoring , watched the you tube video by mike 802 , great video helped me decide to recore myself , nothing terribly hard about it , they have so far been in about 6 months & have around 2000 miles on them , all miles have been with temps in the 90's with bus a/c running towing a 6000 pound excursion , i have kept a good eye on my temp gauge & it never rose out of the normal range . when we went out on our 1st trip / shake down after completing conversion I thought about where to go and decided to head up to niagara falls , about a 6 hour trip each way , thats when one of the original rads blew , i had pulled off the interstate to grab a coffee & wife ran in , I took a walk around the bus and holy c--- there was what looked like 100 gallons of antifreeze on the ground , had to hold in the emegency run button & limped across the street to a travel america truck stop , no worries i had just purchased the day before Coach net premier insurance , not so , turns out they would only pay to tow me to the closest repair facility the next day , i bypassed the leaking rad with some creative plumbing & headed back home , it was only about 60 deg out & did just fine on 1 rad
All radiators are designed per the engine manufactures heat rejection requirements in btu's taking in the consideration of the fans CFM,water pump volume and water circulation over the tubes different manufactures have their own method on how that is accomplished. I'm looking at the tubes and fins on your old radiator and I don't see anything special with it
Ok. Making me feel better. Here's the stats on my radiator:
Length: 24 3/4
Width: 18 1/2
Thick: 7 1/8
8 rows 3/4" tubes
10 fins per inch
Headers: 9.62"x19.625"
40 tubes per row
40x8x0.75=240 cooling units??
Gene burge, what kind of bus and what year are you running
There were two OEM MC-9 radiators, so beware. The bigger of the two was installed with the 8V92 application. I had both MCI part numbers, as we bought several of each, but unfortunately I sold most of my manuals a few months ago (3 cases worth!).
scott my bus is a 1992 mci 102 d , 6v92 turbo , allison auto
Thanks gene. I just noticed you already mentioned that in your first post. I'm sleep deprived. Boomer, I must have gotten the larger radiator. My bus has a repower 6v92 turbo. I'll be making some calls tomorrow. I'm stranded 100 feet away from the sewer dump and our tank is over half full.
Update. Still a little confusion. Just spoke with MCI. They list two part numbers for the radiators on my 1984 MCI 9.
young 6r-1-28D
6k-1-5
1. The 6k-1-5 I thought was the MCI 102 big radiator. If so, that won't fit in my coach without modification correct?
2. Anyone know if the young 6r-1-28D is the smaller radiator for the 6v92 application?
Scott,
I got mine from Diesel radiator in Illinois, They were a 6G-1-9 8 rows, I have in my notes the 6R-1-28D is 6 rows, I did have to modify the back wall a little bit with a hammer. Jason
Ok. Sounds good. Diesel Radiator wants $1540 for one complete radiator. Tanks and all. I just found someone on Minneapolis Craigslist who is willing to send me two completely redone radiators for $1600 plus shipping. I think I'm going that route. His name is Max/Mark. I think he's known by some of you here? Has a bus...involved in the bus clubs...
I don't recognize the name.
Scott I really question the deal or transaction for $1600.00
What are you really buying, used radiators painted black? Or used radiators that were taken apart and were repaired by soldering 20 cores/tubes. Then put back together with new bolts/nuts and then painted black?
$800 a radiator can't get you new cores equal to the MCI radiators.
Well, the deal is done. I can understand you questioning the deal. It really worked out for us both. He needed the funds and I needed the radiators. They are the big ones 8 tube jobbers. He had them recored by diesel radiator in Illinois. Excellent company. They look new but are not spray painted. The labels affixed to
The radiators indicate they were redone by diesel radiator. I looked inside and they look new on the inside too. So so happy. They are heavy as all get out. Took two of us to unload and load them. Excellent deal for us and money in his pocket. This made my month.

Now while you have both out spend the few bucks and rebuild the mitre box and blowers a lot easier now than later ::)
How much is the entire seal kit? Also, how much for two thermostats?
Sent from my iPhone using Tapatalk. Clumsy fingers may contribute to mistakes.
I have no idea for the seal kit, on the thermostats take a candy thermometer and check both in hot water on the stove probably nothing wrong with the 2 you have
Then replace the 5 dollar seals in the thermostat housings most of the time they are the culprit. The thermostats are getting pricey now the 10 dollar stats days are long gone they are now about 50 bucks each now from DD
Scott I have a miter box we rebuilt about 100,000 miles before the coach lost a turbo and ruined the 6V92. All new seals & bearings make me an offer! (been sitting 5-6 yrs now not doing us any good)
;D BK ;D
Thanks BK! :) you're always looking out for me :) I have a pretty intense schedule between now and January and I honestly can't see where I would get a moment free to do a swap. But I may be in touch. You're in KY?
