Detailed Description

Rein CHT0704 is a turbocharger coolant line engineered for the supply position on 2005-2009 Audi A4 and 2005-2009 Audi A4 Quattro models. It is manufactured to OE-quality standards so the replacement follows the original routing and connection points used by the factory cooling system. This makes it a practical choice when servicing a leaking, cracked, or heat-aged turbo coolant hose on an Audi A4 or Audi A4 Quattro.

The hose uses EPDM and aluminum materials selected for the demands of turbocharged engine bays, where elevated temperatures, oil exposure, and ozone can shorten the life of standard rubber components. Rein CHT0704 is intended to restore proper coolant flow through the turbo system and maintain the original system layout.

• Coolant seepage at the turbocharger line
• Cracked or hardened hose material from heat cycling
