I need to replace the radiator in my 2005 Monaco Signature. The engine is an ISX 525 Cummins. I have 3 questions. 1. Does anyone know the part number for the replacement radiator? 2. How labor intensive/complicated is the replacement process? 3. Does it require any special equipment? Thanks in advance!
Had radiator issues on my Cummins engine while traveling through Kingsville, TX. Found Acme Radiator & Muffler shop in town. Small place but great service. Carlos got right on the issue and had me back on the road as fast as could be expected. I thought I would have to have the radiator pulled but Carlos said no and fixed it with new hoses. Honest service and reasonable prices. A big truck shop would have spent much longer and lots more money. Carlos said he could work on any size unit. If you have a problem while in his area I would recommend him.
I thought you might benefit from this. It might save you a gob of money, in the long run. After friends sent their Discovery in for radiator service and ended up with a huge bill, I starting getting more serious about tending to mine*. Bear in mind the buddy who owned mine prior to our purchase periodically raised the closet floor and shot degreaser onto the engine and radiator, and I've done the same every six months or so in nearly two years of steady use. We had been overheating, but only under extreme conditions, eg making 2-mile constant climb at 60 mph in N. Arkansas with 100+F ambient temps (120+ against the pavement). Even then, a short downhill run with the exhaust brake on to boost rpms, or pulling over resulted in immediate return to normal. A recent trip to Galveston resulted in perfect temps, albeit with 85F outside. Still, after the trip, I applied degreaser to the aft side of the radiator, waiting 20 minutes, shot the fins with a safe blast from the hose. What looked like mouse turds showed up in the driveway. Lil' greasy mouse turds that turned into a smudge when rolled between my fingers, rather than the wholesome, nutty but slightly gritty goodness of the real thing... Clearly, the engine side of the radiator was a muffin mold of sorts for these little pellets. Using the heavy duty degreaser in a spray bottle, I hit it from the back side -- the idea was it'd pass through to the engine side -- another five or so times, waiting and rinsing each time. The next morning, I jammed a digital camera up inside the shroud and shot a series of photos. One spot on the lower right was gummed up solid, despite repeated cleaning. So, I got a gallon sprayer and loaded a 1:4 mix of the Simple Green Pro HD from Home Depot yesterday, rated safe for aluminum, sprayed the engine side of the radiator while hot, let it sit for 20 minutes and then rinsed. There was quite a difference, althought further cleaning was needed. As a result of this discovery, I'm programming a misting of degreaser up under the shroud on the engine side, after every trip. It only takes a minute or two, can be paired up with hooking up the black tank rinse, done at the same interval. Thanks for the comments below. Indeed, the moral to the story was that degreaser must always be applied to both sides of the radiator, with an emphasis on the upwind eg front side. Use good judgement to protect the delicate fins: some pressure waters have "Delicate" tips and are appropriate; if in doubt, use a hose-end sprayer.
I have two small leaks in the radiator of my 2000 American Tradition, found during a service inspection. No overheating, no leaking on the ground. Cummins dealer says replace the radiator but wondering if some sort of stop leak product is safe to use and would work. Starting on a long trip.
