Mdmccurr Posted May 19, 2017 Share Posted May 19, 2017 Hello Mack experts, I am restoring a 1978 Mack U Model Tractor with the 237 engine. Unfortunately the Radiator is leaking pretty bad and probably needs a new core. We tried "Stop Leak" with only temporary success. I found a guy on Craigslist who is parting out a 1978 R Model Tractor. He wants $500 for the radiator. Is this a reasonable price for a used Radiator and does the radiator on an R model fit the U Model? Most modern radiators are "throw-away" and there are fewer shops that actually rebuild radiators anymore. Any idea how much it would cost to have a R/U model radiator redone? I appreciate any advice. Thanks, Mike Quote Link to comment Share on other sites More sharing options...

Joe Ditchkus Posted May 20, 2017 Share Posted May 20, 2017 I see adds for radiator cores from companies like Detroit Radiator and others for less than $500.00 I would check around. Was the used radiator ever recored ? Quote Link to comment Share on other sites More sharing options...

Thanks, Mike Mike, when you called your local Mack dealer with the model and serial number (last five digits of the VIN) off the vehicle identification plate on the driver's door and asked about a new radiator (possibly 3MF5296AP2), what did they say?

Bought a core from them for my '70 KW K-100. Just be careful when removing the bolts from your tanks. As always, electrolysis is the enemy in this job. Some of the bolts were a bugger to get out of the aluminum tanks. Easy does it! And don't over tighten the bolts,the gasket "sqwash" is a good indicator of required tightness of the tank bolts. Patience is the key! Al 2 Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!

fxfymn Posted May 20, 2017 Share Posted May 20, 2017 It's a bit of a ride for you, but I'd call L&S Radiator in Richmond to see what they can do. http://www.lsradiatorshop.com/ Quote Money, sex, and fire; everybody thinks everyone else is getting more than they are!

IH Farms 2 Posted May 27, 2017 Share Posted May 27, 2017 The company I worked for had issues with new radiators from Detroit radiator. A lot of failures they did warranty them but some of the warranty ones failed shortly after install. They switched back to only oem after that.

mowerman Posted May 28, 2017 Share Posted May 28, 2017 Good luck can't help you much on this one but yes I would recommend recore as you mentioned these days they're pretty much throw away and I don't think I would feel comfortable with anything used unless it was quite old lol....good luck...bobSent from my XT1096 using Tapatalk Quote Link to comment Share on other sites More sharing options...
