Gates 27555 Radiator Overflow Tubing
Gates 27555 is a practical choice when you need general-purpose radiator overflow tubing rather than a molded, vehicle-specific hose. Its listed feature is weather-resistant EPDM construction, and it is designed for use on a hose-bead fitting with or without hose clamps.
Best for: Buyers replacing a simple overflow tube who can confirm the required size and routing for their vehicle. It was selected because its stated use directly matches radiator overflow tubing.
Limitation: The available product details do not specify tubing dimensions or vehicle applications. Check the required hose size and fit before purchase.
LDCRE Ford Escape Overflow Hose
This LDCRE hose is listed for 2013–2016 Ford Escape models with a 2.0L L4 engine. It replaces part number CV6Z8B081Z, also written as CV6Z-8B081-Z. The product description identifies thickened rubber construction and says it is designed to resist cracking and warping under engine heat and pressure.
Best for: Owners of the specified Escape engine who need a direct-style replacement and can match the OE number. It was selected for its clear year, engine, and part-number information.
Limitation: The listed fitment is limited to the stated Escape years and engine. Do not assume it fits other Escape powertrains or model years.
SWQS Chevrolet Coolant Reservoir Hose
SWQS identifies this as a coolant reservoir, bypass, or upper radiator coolant hose. Listed applications include the 2011–2016 Chevrolet Cruze 1.4L, 2012–2020 Chevrolet Sonic 1.4L, and 2013–2020 Chevrolet Trax 1.4L. The replacement numbers are 13251447 and 13408385. The stated function is to support coolant flow and circulation.
Best for: Drivers with one of the listed 1.4L Chevrolet applications who are replacing a hose by OE number. It was selected because the product information gives specific model, engine, and part-number details.
Limitation: The listing explicitly excludes some model and engine combinations. Confirm your exact year, model, and engine rather than relying on the vehicle name alone.
Uselection Audi Coolant Hose Set
This four-piece set lists OE numbers 8W0121081BL, 8W0121081BK, 8W0121081AN, and 06L121081K. Its stated applications include select Audi A4 and A5 models with 1.4L or 2.0L engines, with year ranges beginning in 2016 for A4 models and 2017 for A5 models.
Best for: Audi owners whose vehicle and existing hose number match the listing. It was selected for its multiple OE references and coverage across specified A4 and A5 variants.
Limitation: The year ranges vary by model and body style. Check the exact Audi trim, engine, and OE number before choosing a set.
VekAuto Ford Fiesta Overflow Hose
VekAuto lists this hose for Ford Fiesta 1.6L applications, including S and SE models from 2011–2019, certain SEL and SES models from 2011–2012, and specified ST and Titanium versions. It references OE numbers 8V2Z-8B081-B and 8V2Z-8B081-A and states that the hose is manufactured to precise dimensions without modification.
Best for: Fiesta owners who can verify their trim, year, engine, and OE number. It was selected as a vehicle-specific option with detailed application information.
Limitation: Fitment varies by trim and year; the broad Fiesta name alone is not enough to establish compatibility.
Buying Guide: How to Choose a Radiator Overflow Tank Hose
Should you choose universal tubing or a molded replacement?
Universal tubing can suit a straightforward hose-bead connection when its diameter, material, and required length match the vehicle. A molded, vehicle-specific hose is generally the better direction when the original part has bends, connectors, or a defined routing path. The products above do not all provide the same level of dimensional detail, so check measurements when they are not listed.
How do you confirm fitment?
- Match the vehicle’s year, make, model, and engine—not just the model name.
- Compare the replacement hose’s OE or part number with the number on the original part or a vehicle parts reference.
- Check whether the listing describes an overflow tube, reservoir hose, bypass hose, or another coolant hose; those terms can refer to different components.
- Inspect the existing hose routing and connection style before ordering.
What material and condition details matter?
Look for product information relevant to the intended cooling-system location, such as stated heat resistance or weather-resistant material. Replace a hose that is cracked, damaged, or no longer functioning properly, and confirm that the replacement can be secured at the vehicle’s fittings. Product descriptions differ in detail, so avoid assuming that an unspecified dimension or application will fit.
Frequently Asked Questions
What does a radiator overflow tank hose do?
It carries coolant between the cooling system and the reservoir or overflow tank, depending on the vehicle’s design. The exact hose path and function vary by application.
Can I use vacuum tubing as a coolant overflow hose?
Only if its material, dimensions, and intended use are suitable for the vehicle’s requirements. Verify those details rather than assuming every vacuum tube is appropriate for coolant service.
How do I know which hose part number I need?
Compare the number on the original hose with the replacement listing, and verify it against your vehicle’s year, engine, and trim.
Are radiator overflow hoses interchangeable across trims?
Not necessarily. Engine, model year, and trim can affect hose shape and connections, so confirm the specific application before buying.
