Detailed Description

Rein CHH0529 is a single heater hose assembly made for direct OE-style replacement on select Volkswagen and Audi models. The hose measures 22 inches centerline length and uses EPDM material for durability in demanding underhood conditions. With one quick connect fitting and a branch layout that follows the original routing, this hose supports a precise repair on the heater outlet pipe to flange to transmission oil cooler circuit.

This part is a practical choice for Audi A3, Audi A3 Quattro, Volkswagen GTI, Volkswagen Eos, Volkswagen Beetle, Volkswagen Jetta, and Volkswagen Golf applications where the original hose assembly has aged, cracked, or begun to leak. Rein CHH0529 is identified by part number CHH0529 and is built to match OE dimensions rather than requiring modification.

Common Repair Uses

• Coolant seepage at the heater hose connection
• Cracked or brittle hose material from heat cycling
• Leaking quick connector or worn O-ring interface
• Incorrect hose fitment after prior repair attempts
• Repeat HVAC coolant loss on Volkswagen and Audi platforms

Installation Notes

Install CHH0529 as a direct replacement for the original hose assembly on the listed vehicles. Because the hose is built to OE dimensions, no cutting or refitting is required. Inspect the mating surfaces, connector condition, and surrounding coolant passages before installation, and verify the routing matches the original heater outlet pipe to flange to transmission oil cooler layout.

Quality Assurance

Rein designs this heater hose to OE quality standards for European vehicles, with fit and connector geometry based on the original assembly. Part number CHH0529 is backed by a 24-month or 24,000-mile warranty.
