Technical Tidbits: Charge Air Cooler and Radiator Failure Issue

What Country Coach Motorcoach Model Years was there a potential of the Radiator / Charge Air Cooler Failure Issue to Occur?

Owners of the 2002-2007 model year Country Coach motorcoaches (also some 2000 and 2001 models) have experienced a Radiator (coolant/oil) failure issue and a Charge Air Cooler cracks causing a loss of turbo boost with accompanying loss of power/speed pulling hills.

Radiator - With the radiator failure issue, there is a likelihood of a failure occurring in the joint between the end tank and the core in the aluminum radiators installed in CCs in the 2002-2007 model year range.  The engine’s side mounted cooling fan kicks in drawing up to 45HP energy off the engine. Each time the engine reaches a certain temp the engine fan kicks on. As it is shroud mounted and bolted to the radiator core that vibration and energy from the fan is right against the tanks. It can rip apart at the faulty weld, if you have a radiator with this fault issue. A radiator replacement is the fix in this situation.

Charge Air Cooler – On a Country Coach the charge air cooler is between the radiator and the condenser and the oil cooler, all bolted together (looks like a box). Charge Air Coolers as originally installed in 2002-2007 models featured a bolt-together construction. When aluminum expands and contracts with heating and cooling, wear and tear and failure can occur. If the Charge Air Cooler is cracked and leaks, the engine runs hot, causing accelerated wear and potential engine failure.  A Service Center with knowledge of the Country Coach product lines and model year build processes will be able to help you assess whether your motorcoach may have this Radiator or Charge Air Cooler issue.
