Clear part-number identification, detailed compatibility guidance and actual-item photographs to help you order correctly first time.
FITMENT CHECK REQUIRED BEFORE ORDERING
Do not order this coolant hose from registration year, model name or appearance alone.

The physical hose in this listing is visibly marked 8V21 18K579. Ford service-number cross-reference: 1521014.

For the safest match, compare the number on your existing hose, the complete connector arrangement and the hose shape. If your existing number cannot be read, provide your vehicle's 17-character VIN through eBay messages before ordering so the catalogue application can be checked.

Important: the donor vehicle VIN and exact 3-door/5-door body style are not visible in the source listing, therefore we do not guess those details.

Actual Part Photographs

These are photographs of the actual used hose from this listing, hosted directly on eBay's HTTPS image network. Please compare the moulding, connectors, retaining hardware and visible markings with the part removed from your vehicle.

Part Identification

Visible Engineering Number

8V21-18K579

Clearly visible on the photographed hose. Match this number first.

Ford Service Number

1521014

Manufacturer catalogue service-number cross-reference for this heater-hose family.

Part Type

Heater Matrix Coolant Hose

Also commonly described as a heater water hose or bulkhead coolant hose.

Condition: Used manufacturer-marked Ford part. The actual component shown in the photographs is the item being described. Used parts can show normal cosmetic marks, dust and evidence of previous installation.

Construction: moulded flexible coolant-hose assembly incorporating a formed connector section and metal retaining/clamp hardware. The exact elastomer compound is not legible from the photographed markings, therefore no unverified rubber specification is stated.

Primary UK Fiesta Compatibility

The table below is deliberately conservative. It identifies the principal UK Mk7 Fiesta 1.25 application but still requires the buyer to match the part number or obtain a VIN check.

Vehicle UK Years Engine Power Engine Codes Fitment Status
Ford Fiesta Mk7 / Fiesta VI Hatchback 2008-2017 1.25 Petrol, 1242cc 44kW / 60PS STJA, STJB, STJC, STJD Part-number application - VIN/number match required

3-Door / 5-Door Buyers

Do not use door count alone to select this hose. The source listing does not expose the donor VIN or donor door count. Compare the hose number and connector arrangement or request a VIN check before purchasing.

Additional Manufacturer Catalogue Cross-References

Ford's service catalogue also associates service number 1521014 with the vehicle families below. These are shown to help identification, not as blanket guaranteed fitment. Production markets, build dates, air-conditioning specification and revisions can alter the hose used. A VIN and part-number match are required before purchasing this listing for one of these applications.

The quick connector, clip, hose bends or branch layout differ from the photographs Physical connection may be incompatible
You are selecting solely from registration year or engine capacity Multiple cooling-system revisions can exist within one model year
You are relying solely on 3-door or 5-door body style Door count is not sufficient evidence for this cooling-system component
Your VIN catalogue does not return Ford service number 1521014 for the required heater-hose position Do not fit this part

Where Is This Part Fitted?

ENGINE COOLING CIRCUIT   |   HEATER HOSE   |   BULKHEAD AREA   |   CABIN HEATER MATRIX

This hose forms part of the vehicle's engine-coolant/heater circuit and is positioned around the engine-bay/bulkhead heater-matrix connection area. Its purpose is to route coolant through the heater circuit.

What does it control? This is not an electrical control unit and does not electronically operate the heater. Its job is fluid transfer: maintaining the intended coolant path between the engine cooling system and heater circuit.

Because no verified donor VIN or engine-bay reference photograph is contained in the source listing, we have intentionally not shown a random vehicle or engine-bay photograph that could give a false impression of exact fitment.

Common Symptoms of a Deteriorated Heater Hose

Coolant Loss

Coolant level gradually dropping or visible wetness around the hose, connector or clamp area.

Coolant Deposits

Dried staining or crusted residue around a leaking connection can indicate previous coolant escape.

Coolant Odour

A noticeable coolant smell around the engine bay or heater area can accompany a leak.

Reduced Cabin Heat

Loss of coolant or air entering the cooling system can cause inconsistent heater performance.

Steam or Dampness

A significant leak may produce visible moisture or steam when the cooling system reaches temperature.

Overheating Risk

A substantial coolant loss can eventually reduce cooling-system performance and should not be ignored.

Never remove a coolant cap or disconnect a cooling-system hose while the engine is hot or pressurised. Hot coolant can cause serious burns.

Why Replace a Damaged Hose?

Cooling-system hoses operate through repeated heating and cooling cycles. Age, heat exposure, pressure, movement at the engine and deterioration around connectors can eventually result in seepage, cracking or connection failure.

Correct hose geometry matters because the hose must follow the intended route without kinking, stretching or placing unnecessary load on adjoining fittings. Matching the manufacturer number, connection type and moulded shape therefore gives much stronger fitment evidence than selecting a similar-looking hose.

A used manufacturer-marked component can provide an economical route to maintaining the original connection layout. On selected vehicle parts, buying used can save up to 70% compared with buying new, although the actual saving varies by component and current market price.

Typical Fitting Procedure

Cooling systems can retain heat and pressure for a long time after the engine has been switched off. Work only on a completely cold vehicle. If you are not experienced with cooling-system repair, use a competent workshop.
Confirm the VIN, engine specification and part number before dismantling the vehicle.
Allow the engine to cool completely and place the vehicle securely on level ground.
With the system completely cold, relieve any remaining cooling-system pressure in accordance with the vehicle workshop procedure.
Position a suitable drain container and lower the coolant level sufficiently to prevent uncontrolled spillage when the hose is disconnected.
Photograph the existing hose routing and note the orientation of every connector, clamp and retaining clip before removal.
Release the retaining hardware carefully. Do not force or lever against an adjoining plastic coolant connection.
Remove the old hose and inspect both mating connections for damage, contamination, corrosion or damaged sealing surfaces.
Compare the replacement part side-by-side with the removed hose: number, length, moulded bends, connector diameter, retaining features and orientation must agree.
Install the replacement hose fully into position and ensure each retaining mechanism is completely seated and locked.
Refill only with the coolant specification required for the exact VIN and bleed the cooling system using the correct vehicle-specific procedure.
Bring the engine to operating temperature, confirm heater operation and inspect every disturbed joint carefully for leakage.
After the vehicle has cooled again, recheck the coolant level and inspect the repaired area once more.

Typical Tools Required

Safety Equipment

Protective gloves, eye protection and suitable workshop clothing.

Coolant Handling

Drain container, suitable funnel and materials for dealing safely with accidental coolant spills.

Hand Tools

Hose-clamp pliers, suitable pliers, small hand tools and a socket/ratchet set as required for access.

Vehicle Data

VIN-specific coolant specification and the correct workshop filling/bleeding procedure.

Tool requirements vary with engine specification, access and previous repairs. This is a planning guide rather than a substitute for VIN-specific workshop information.

Estimated Workshop Time & Labour Cost Guide

For planning purposes, allow approximately 0.75 to 1.5 workshop hours for hose access, coolant management, replacement, refill, bleeding and final leak checks. This is an estimated planning range rather than a manufacturer flat-rate time.

Labour estimate formula: Garage hourly rate x time taken.

Garage Labour Rate 0.75 Hour 1.0 Hour 1.5 Hours
£50 per hour £37.50 £50 £75
£60 per hour £45 £60 £90
£70 per hour £52.50 £70 £105
£80 per hour £60 £80 £120
£90 per hour £67.50 £90 £135
£100 per hour £75 £100 £150
£120 per hour £90 £120 £180

Coolant, seals, clips, diagnostic work, additional repairs and VAT charged by an independent garage are not included in these examples.
