ContiTech 63525 Molded Heater Hose

The ContiTech 63525 is a precision-molded heater hose engineered to deliver reliable coolant flow between the engine and heater core. Manufactured by ContiTech — a Continental brand and global leader in rubber and polymer technology — this molded hose is designed to maintain its pre-formed shape for a direct, rattle-free fit in specific vehicle applications.

ContiTech molded heater hoses are built with a multi-layer construction featuring an EPDM (ethylene propylene diene monomer) rubber compound that resists heat, ozone, and coolant degradation over the long term. The molded design eliminates the need for field bending, ensuring proper routing and reducing the risk of kinking or collapsing under pressure.

Key Features:

• Pre-molded shape for precise, direct-fit installation
• EPDM rubber construction for superior heat and ozone resistance
• Engineered to withstand high coolant temperatures and pressures
• Resists electrochemical degradation (ECD) that can cause premature hose failure
• Meets or exceeds OEM specifications for a reliable, long-lasting repair
• ContiTech quality — a trusted Continental brand with global OEM heritage

Designed as a direct OEM replacement, the ContiTech 63525 restores proper heater system performance and helps prevent coolant leaks. It is an ideal choice for technicians and DIY mechanics seeking a factory-quality heater hose replacement.
