spartan says they don't carry it looking for radiator

MAC's radiator will rebuild your radiator, and they probably have the dimensions on hand to built a new one if you prefer.

going to radiator shop tomorrow finally got that bugger out of there they silicone the radiator to the air charger and also to the transmission cooler I had to cut those lines out on transmission cooler so looks like a radiator repair and weld new connections back on cooler ya I could of used stop leak but I couldn't do that to the next owner of this coach as we are looking for a newer coach now I think most of us are that way with a motorhome we meet great people rving all the time ok later.

Radiator shop yup.

Radiator on my 2000 Spartan chassis started leaking late last year. I removed the radiator myself and took it to a local radiator shop. The completely rebuilt it for less than the radiators I found online to replace mine. I put it in and have just returned from a 6000 mile cross country journey and all is well.

There are two kinds of shops now days. OLD and NEW

The new shops are just replacement shops You bring you ride in they figure out what is bad and order a new one and put it in. Easy Peasy.

But the old style shops FIXED things.. A raditor for example has several modules The upper tank, lower tank, Transmission cooler (often part of lower tank) and so on.. What a Radiator REPAIR shop does is remove the top and bottom tanks if they are good RE-CORE the thing (that is the heat exchanger part) and put it back in... Unless the problem is a bad tank. these shops should be able to fix ANY radiator.

Any good radiator shop will dismantle your old radiator and keep the upper and lower tanks and mounting brackets. Then they will replace the core with an off the shelf unit to replace your old radiator core. The problem is that most shops cannot deal with an RV so you must remove the radiator and take it to them.

Radiator shop should be able to get replacement if unable to fix yours
