The level of communication between Albuquerque Rocky Mountain Cummins and me has been poor at best. With that in mind, I decided to pay the shop a visit on Thursday afternoon to check on progress and see if they had confirmation of shipment of the new Charge Air Cooler (CAC).

I asked the Service Coordinator, Philip, about it. He picked up the phone on his desk and called the radiator shop. Then he told me the CAC had shipped and they expected it no later than Friday. I took this as good news. We walked out to the shop so I could retrieve a couple more items from the coach.

Before I left, Philip said, “Of course, if they have the CAC tomorrow, it doesn’t mean we’ll able to have the coach ready then.” I told him I understood – the radiator shop had to assemble the radiator stack and get it back to the shop. The mechanic had to finish putting the turbo assembly on the engine and install the cooling stack. I asked him if he thought Tuesday was realistic. He said he thought it was, but then he dropped a bomb. He told me they hadn’t received the replacement turbocharger yet.

I kept my mouth shut but thought, “What?” Last Monday they told me they would have the part by the next day. This potentially complicates matters. The mechanic will want to install the exhaust manifold and turbocharger before he installs the radiator stack. If he installs the stack – engine coolant radiator, CAC, hydraulic fluid cooler and AC condenser – he will limit the accessibility to the engine and exhaust system.

Yesterday I stopped by the shop in the afternoon again. As I said, communication isn’t their strong point – I figure if I want an update, I’d better stop in and ask. Philip confirmed the CAC had been delivered but then told me they should have the replacement radiator core on Monday! What? Again I bit my tongue – this was the first time any mention was made of needing to order the core and any delay with it.

The radiator core is the center portion of the radiator. It consists of tubes running from the radiator inlet tank to the outlet tank. Coolant passes through these tubes from one tank to the other. Thin aluminum or copper fins are attached to the tubes to transfer heat from the coolant to the air passing through the fins. Our radiator core had corrosion and the radiator shop was replacing the core, reusing the original tanks and end plates.

But wait, there’s more – Philip lobbed the final bomb. There was a problem getting the turbocharger. He said one had been located by Cummins, but it was in a warehouse in New Jersey that wasn’t operational at this time. Apparently, the warehouse is unmanned but it holds the only turbocharger in the country to fit our coach. He said the Cummins Holset turbochargers used on motorhomes have unique fittings and linkages.

He went into the service manager’s office to talk to the manager, Alvaro. He came out a minute later and told me their parts manager was working on a solution with Cummins, but wasn’t present at the moment. He said I should come back Monday morning to learn the disposition of the part in the warehouse. I think we’re in real trouble here.

The hotel has already informed me that we’ll be kicked to the curb on Wednesday. All the rooms in the area are booked for the Albuquerque International Balloon Fiesta. It’s the largest hot air balloon event in the world and it’s impossible to find a vacancy from a few days before the fiesta until the end two weeks later.

All I can do at this point is wait until Monday and hope for the best. Donna will return Tuesday night. I’m holding on to some hope they’ll be working on the coach by then.

We’ve had a series of thunderstorms passing through since Wednesday and that has hampered my activities. Yesterday, after I left the shop, I went to Rio Bravo Brewing. I looked for the owner, Randy, but he wasn’t in. He’d promised a brewery tour. The bar manager took me back to the brewhouse. When I mentioned I had experience with home brewing, he was relieved not to have go through the brewing 101 spiel about how beer was made and cut right to their equipment and processes. The brew master, Ty Levis, was there and he gave me a one-on-one tour and talked about some advanced techniques he uses and some experimental brews he’s working on. It was one of the best brewery tours I’ve had. I didn’t take any photos because they all start looking the same – stainless steel fermenters and mash tuns, etc.

An interesting thing I learned at Rio Bravo had to do with the canned beer they distribute. The four-packs are held together with what looks like plastic rings, just like you find on most six-packs. But they’re not. They are biodegradable, I think he said they’re made from corn starch. Don’t get the four-pack wet – it might disintegrate into loose cans!

I don’t have any big plans for the weekend – I’ll just wait and see what comes next.
