Product Details
Features
- Flexible stainless steel hose routes coolant to and from the heater core
- Includes 5/8" and 3/4" adapters to match mismatched heater core and block ports
- 44" length allows custom routing around firewall and engine bay obstructions
- Sold without end caps — confirm your port connections before ordering
Description
This polished stainless steel flexible heater hose kit connects the heater core to the engine or block heater port, with flexible construction that allows custom routing around firewall and engine bay obstructions rather than following a fixed factory hose path. Two hoses are included at 44" length and 3/4" OD, along with four hose adapters — two at 5/8" and two at 3/4" — to match ports of different sizes on each end.
This kit is sold without end caps. Confirm whether your application connects directly to threaded or barbed ports without additional caps, or whether a separate end cap kit is needed before ordering. Hose clamps are included; a hose clamp cover is not.
Port and Adapter Sizing
This kit includes two adapter sizes — 5/8" and 3/4" — since heater core and engine/block heater ports are often different diameters from each other. Confirm which adapter size matches your heater core port and which matches your engine or block port before routing, since the two ends of a single hose run may not use the same size.
Routing and Length
The 44" overall length and flexible stainless steel construction allow custom routing around engine bay obstructions rather than requiring a fixed hose path. Confirm this length provides enough slack for your specific firewall-to-block or firewall-to-intake routing before cutting or trimming.

Q&A
Does this kit include end caps?
No — end caps are not included. Verify whether your application connects directly to the supplied adapters or requires separately sourced end caps or additional fittings.
Why are there two different adapter sizes included?
The kit includes both 5/8" and 3/4" adapters to accommodate different heater-core and engine-side connection sizes commonly found in heater-hose routing.
Are the two hoses in this kit the same length?
Yes — both hoses are 44" long, providing flexibility for custom routing between the engine and heater core.
Does this kit include hose clamps?
Yes — hose clamps are included. Hose clamp covers are not included.
Can I cut this hose to a shorter length?
Yes — the 44" length provides extra material for custom routing and can be trimmed to fit your installation. Measure and confirm your routing before cutting.
What's the hose diameter?
The listed hose size is 3/4" OD (outside diameter).
