Ford Fiesta Mk7 2008-2017 1.25 Petrol Heater Matrix Hose 8V21-18K579 1521014
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
Clearly visible on the photographed hose. Match this number first.
Ford Service Number
Manufacturer catalogue service-number cross-reference for this heater-hose family.
Part Type
Also commonly described as a heater water hose or bulkhead coolant hose.
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 |
| Ford Fiesta Mk7 / Fiesta VI Hatchback | 2008-2017 | 1.25 Petrol, 1242cc | 60kW / 82PS | SNJA, SNJB, SNJC, SNJD | Part-number application - VIN/number match required |
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.
| Vehicle Family | Ford Catalogue Window | Engine | Engine Codes / Specification | Status For This Used Part |
|---|---|---|---|---|
| Ford Fiesta Hatchback | From 2008 | 1.4 Petrol 1388cc | RTJA, RTJB, SPJA, SPJC, SPJE | VIN verification required |
| Ford Fiesta Hatchback | From 2008 | 1.6 Ti Petrol 1596cc | HXJA, HXJB, HXJE | VIN verification required |
| Ford Fiesta Hatchback | From 2012 | 1.6 Ti Petrol 1596cc | IQJA, IQJC, IQJE | VIN verification required |
| Ford Fiesta Van | From 2009 | 1.25 Petrol 1242cc | SNJA, SNJB, SNJC, SNJD | VIN verification required |
| Ford B-Max MPV | From 2012 | 1.4 Petrol 1388cc | SPJD, SPJE | VIN verification required |
| Ford B-Max MPV | From 2012 | 1.6 Ti Petrol 1596cc | IQJA, IQJC | VIN verification required |
| Ford KA+ Hatchback | 2016-2020 catalogue window | 1.2 Petrol 1198cc | B2KA | VIN verification required |
| Ford KA+ Hatchback / Saloon | 2015-2018 catalogue window | 1.5 Petrol 1499cc | UEJB | VIN verification required |
| Ford Fiesta Hatchback | From 2012 | 1.5 Diesel 1499cc | UGJC, XUJA, XUJB | VIN verification required - do not order from model alone |
Manufacturer catalogues can retain wider international service windows than the UK model-generation dates. Your 17-character VIN and the number on the removed component remain the safest identifiers.
Vehicles / Situations This Listing Should NOT Be Used For
| Do Not Order When | Reason |
|---|---|
| Your existing engineering/service number is different | Part revision or hose specification may differ |
| 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?
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.
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
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.
