Nissan Qashqai J11 MK2 2014-2018 1.5 dCi K9K Coolant Reservoir Hose
Nissan Qashqai J11 MK2 2014-2018 1.5 dCi K9K Coolant Reservoir Hose
Nissan Qashqai J11 1.5 dCi K9K Coolant Reservoir Pipe / Hose
Part number 21742-4EA0A / 217424EA0A. Used original-manufacturer cooling-system component. Fitment is deliberately restricted to verified applications to help buyers order the correct part first time.
Exact item — study the photographs before ordering
Verified identity & technical specification
Vehicle reference — correct J11 5-door body shape
Why we do not guess from a vehicle photo
Different engines can share the same exterior body. A J11 that looks identical may use a completely different cooling pipe. We therefore combine body/chassis + engine + transmission/drive + OE reference + physical photo match + VIN.
Reference vehicle image is a reusable CC0/public-domain dedication image. It is not a photograph of the donor vehicle.

VIN-TIED DONOR CROSS-CHECK | K9K646 donor example with 217424EA0A has been cross-checked. Confirm your own VIN before ordering. |
| Later J11 1.5 dCi K9K builds | K9K-family | VIN CHECK ONLY | The catalogue continues the K9K application after 06/2017, but no end date was stated in the verified data. We will not advertise later years as guaranteed without VIN confirmation. |
Do NOT order this part for the following without a positive VIN/part-number confirmation
| Vehicle / configuration | Fitment position |
|---|---|
| Qashqai J10 / Qashqai+2 first-generation vehicles | NOT THIS APPLICATION |
| Qashqai J12 third-generation vehicles | NOT THIS APPLICATION |
| Qashqai 2.0 petrol MR20DD | DO NOT USE — different engine application |
| 1.2 DIG-T, 1.3 DIG-T, 1.6 dCi, 1.7 dCi, 1.6 DIG-T and other non-K9K engines | DO NOT USE unless the exact OE number is independently confirmed |
| 4WD variants | CATALOGUE APPLICATION CHECKED IS 2WD |
| Automatic / DCT / CVT variants | VIN CHECK REQUIRED — verified catalogue row is F6 manual |
| Renault Kadjar or any other vehicle line | NOT ADVERTISED AS CONFIRMED — marketplace references alone are not enough for us to guarantee cross-fitment |
Where the part is fitted & what it does
Front engine-bay cooling circuit
This assembly is catalogued as the reservoir-tank hose within the radiator/shroud cooling group. Its job is to route engine coolant through the reservoir branch of the cooling system and maintain the intended coolant path and sealing integrity.
It is a fluid-routing component, not an electronic controller. A leak, restriction or damaged connection can nevertheless affect cooling-system pressure, coolant level and engine temperature control.
Possible symptoms of a failing coolant pipe / hose
Expansion/reservoir level gradually falling with no obvious radiator damage.
Damp joints, staining or dried coolant residue around the pipe, hose ends or clamps.
Sweet coolant odour, vapour or steam after driving can indicate a pressurised leak.
Low coolant or loss of pressure can contribute to overheating or a temperature warning.
Air entering the cooling system can sometimes cause fluctuating cabin-heater output.
A workshop pressure test may reveal a leak that is difficult to see when the engine is cold.
These symptoms are not unique to this component. Thermostat, pump, radiator, expansion tank, cap, other hoses or sealing faults can produce similar symptoms. Diagnose before replacing parts.
Why choose an original-manufacturer used part?
- Correct factory geometry: bends, diameters, retaining points and routing were designed for the intended vehicle installation.
- Better comparison: you can match the removed part directly against the photographed factory component and OE reference.
- Reduced routing risk: the correct shape helps avoid kinks, tension, contact with hot/moving components or incorrect clip alignment.
- Used-part value: depending on the component and market price, buying quality used parts can save up to 70% versus buying new. Actual saving varies by part.
- Reuse matters: extending the useful life of serviceable components reduces demand for new material, manufacturing and disposal.
Fitting guide, tools & estimated workshop time
Typical tools
- Basic socket and ratchet set
- Hose-clamp pliers and/or long-nose pliers
- Trim tool / screwdrivers as required for access
- Drain pan and suitable coolant-handling equipment
- Hose pick used carefully to avoid damaging sealing surfaces
- Torque wrench
- Cooling-system filling / bleeding equipment
- Cooling-system pressure tester recommended
- Gloves and eye protection
General fitting sequence
- Before dismantling, verify the full VIN, OE reference 21742-4EA0A and physical pipe/hose shape.
- With the engine completely cold, safely release any residual pressure and drain enough coolant to prevent uncontrolled spillage.
- Photograph the original routing and clamp/retainer positions before removal.
- Remove any covers or intake ducting required for safe access.
- Release hose clamps, retaining clips and bracket fasteners; remove the assembly without levering against fragile plastic fittings.
- Place old and replacement parts side-by-side. Confirm bends, end diameters, brackets, hose lengths and orientation before installation.
- Inspect clamps, seals, adjacent hoses and connection necks. Replace damaged consumables rather than reusing suspect items.
- Install without twist, kink or contact with moving/hot components. Tighten fasteners to the Nissan service information specification for the exact VIN; no torque value is guessed here.
- Refill with the coolant specification required for the VIN, bleed the cooling system using the correct procedure, run to operating temperature and check for leaks.
- Pressure-test where appropriate and recheck coolant level when fully cold.

VAT margin / Global Accounting scheme
Where applicable, this used part is sold under the Global Accounting / VAT Margin Scheme. VAT is accounted for within the scheme and is not shown separately as a reclaimable VAT amount.
Returns — fitment matters
Please use the fitment chart, actual photographs, OE reference and VIN-check service before ordering. Parts should be returned in the same condition in which they were supplied.
If a returned component has been fitted, used, damaged, altered, contaminated, is incomplete or otherwise comes back in a different condition, eBay may allow a deduction from the refund for loss in value, including up to 50% where eBay's rules make that deduction eligible. This is not an automatic 50% restocking fee and does not remove a buyer's valid rights where an item is not as described.
Checkout delivery address
Please check your eBay delivery address before paying. Orders are dispatched only to the delivery address attached to the eBay order. We cannot manually redirect an order to a different address after checkout; where possible, an incorrect-address order may need to be cancelled and placed again correctly.

- Does your removed part show or cross-reference to 21742-4EA0A / 217424EA0A?
- Do the bends, hose ends, mounting/retaining points and protective sleeve visually match the actual item photographs?
- If any answer is uncertain, do not guess — send the full 17-character VIN through eBay Messages before ordering.
Supporting reuse, local business & the circular economy 🌍♻️
Choosing a serviceable used vehicle component keeps an existing part in productive use and can reduce the material, manufacturing, packaging and waste associated with replacing every component with a newly manufactured item. Buying from an independent local automotive parts business also supports skilled dismantling, identification, storage, packing and customer-fitment support.
At ThePartPilot, the focus is simple: identify carefully, describe clearly, reuse responsibly and help the buyer get the right part first time. 🔧📦🚗
