Continental Flexible Coolant Hose 1-1/2" x 15-3/4" — Wire-Helix Reinforced, Corrugated for Easy Routing

Continental 52415 is a wire-helix reinforced flexible coolant hose sized 1-1/2" x 15-3/4" made to replicate molded radiator lines while keeping full coolant flow and resisting collapse.

This flexible coolant hose from Continental is engineered for radiator and heater line repairs when an exact molded replacement isn't available. Its corrugated exterior lets the hose bend to match original routing without kinking, while an internal wire helix keeps the passageway open under vacuum or engine movement. The construction is optimized for use with standard automotive coolants and meets SAE J20R5 D1 specifications for flexible coolant hose performance.

How does this hose fit where a molded radiator hose won't?

The corrugated cover and pliable body allow the hose to be shaped around tight engine bay paths that a rigid molded hose can't follow. You can hand-bend the hose into the needed curvature and secure it with clamps at each end. Its flexibility reduces the need for precise pre-formed replacements in many repair situations.

• Corrugated outer profile for easy bending and routing
• Available length and diameter suitable for many radiator and heater applications
• Can be trimmed to exact length at installation

Will the hose maintain coolant flow and resist collapsing?

Yes—the internal wire helix is embedded to hold the lumen open even under pressure changes and engine movement. This reinforcement prevents inward collapse under suction or when routed tightly, so coolant can circulate without restriction. The synthetic knit and design also provide dimensional stability over time.

• Wire helix reinforcement prevents lumen collapse
• Synthetic knit carcass for consistent flow characteristics
• Designed to withstand repeated flexing without occluding flow

Is this hose compatible with engine coolants and safe to use in radiator systems?

The Continental 52415 is formulated specifically for use with automotive coolants, including ethylene- and propylene-glycol based mixtures. It meets SAE J20R5 D1 standards, which cover hot and cold flexible coolant hose requirements. Avoid using this hose for fuels, oils, or other fluids for which it is not designed.

• Rated for automotive antifreeze and coolant fluids
• Conforms to SAE J20R5 D1 specification for coolant hoses
• Not suitable for fuel or oil service

What should I know about installation and trimming?

Trimming to length is straightforward with a clean, square cut and appropriate hose clamps at each end to secure connections. Slide clamps over the hose before fitting it onto the fitting, then position clamps behind the wire helix area for best seal. Inspect clamps periodically and replace if signs of wear or loosening appear.

• Use a sharp cutter for a clean end; avoid crushing the corrugation
• Place clamps behind the helix to ensure a reliable seal
• Check routing to prevent chafing against sharp edges or hot surfaces

Who is this product for? The Continental 52415 flexible coolant hose is ideal for mechanics, DIY car owners, and fleet maintenance teams who need a dependable replacement when molded hoses are unavailable. It suits vehicles requiring a flexible, wire-reinforced radiator or heater line that preserves coolant flow and resists collapse. Choose this hose when you need an adaptable, spec-compliant solution for coolant circulation in passenger cars, light trucks, and similar applications.
