CAC repair by Fleet Air Technology

I recently had to have my CAC repaired due to multiple leaks, including core leaks as well as a split tank seam. On the advice of Walt, I called Fleet Air Technology in Martsell, AL. I talked to Jeremy. He was very knowledgeable and very familiar with the Monaco CAC’s. He described the common problems, and they were exactly the ones I had. Jeremy said the majority of the OEM coolers had flimsy cores and that repairing them was failure prone. He said he could only recommend replacing the core, and performing their entire restoration process, including a proprietary sealing procedure. He estimated, without seeing the CAC, that the repair would be about $1200 plus freight. Freight from NC was just over $100 each way. I sent it to them. The freight company had the CAC to him the next day and promptly the following morning he called me to say that either my CAC was different than those he was familiar with in Monaco’s or it had at some time been replaced. Jeremy said he would re-use my core and that the total repair would be about half what he had estimated.

Less than a week later, I had the skillfully repaired CAC back and looking like new. Being a bit of a skeptic, I pressure tested it before reinstalling. It was OK. I do not have many miles on the repaired cooler, but feel certain it is OK.

The point I want to make is this—How often does someone charge you a lot less than what he estimated, when if he had done what he said originally, you would never have known? That is uncommonly good customer service. And Jeremy was a very pleasant person to deal with. I would heartily recommend Fleet Air Technology if you are ever in need of this type service.

I had to have my CAC redone, as well. I did the removal of it myself and took it to Webster Radiator here in Concord, NC. Little over $1,000 for mine to be completely redone. Man does it look much better, and stronger!

Your CAC is located back there by your radiator. It looks like a radiator, but if you can see the entry or output hose they are probably about a 4" hose. The CAC cools the hot air coming from the turbo on its way to the intake. The problem with Monaco CACs is that they didn't put in very expensive ones in and they crack or the solder used on the end connections was not a high enough temperature for this use. Normally the solder connections on the hot end, turbo out, give up first. If you have a boost guage on your dash watch for how fast the boost goes to max when you hit the accelerator. It should go up to around 30 in about two seconds. If it doesn't go that high or takes a bit longer you are on your way to having CAC problems or Turbo Charger Problems. Either really affect engine performance. The CAC is necessary because the turbo output air temperature is hot enough to damage the engine intake, and engines like cool air.

An easy check of the CAC is to have someone hold the accelerator at about 1200 RPM and spray some soapy water on the CAC. No soap bubbles is good.

I too wondered what CAC stood for. Now I know it's a charge air cooler. Why don't they just call it what most manufacturers call it - an intercooler???
