Renault 1.9 dCi 120 2006 coolant hose identification by photo or VIN

User question

coolant line for engine or phot 120 dci 2006

Artificial Intelligence Response

Direct answer to the question

I cannot identify the correct coolant line/hose from “phot 120 dci 2006” alone. Most likely you mean a photo or a coolant hose for a 2006 Renault 1.9 dCi 120. In Renault documentation from that period, 1.9 dCi 120 appears on vehicles such as the Mégane and Espace, and the cooling hoses are different by exact vehicle model/code, even when the engine family is similar. (media.renault.at)

Key points

  • “120 dCi” in this 2003–2006 Renault context is typically 1.9 dCi 120, not a single universal hose. (media.renault.at)
  • Renault parts catalogs split the cooling system into several separate lines/hoses such as:
    • radiator inlet tube
    • radiator outlet tube
    • inlet pipe to pump
    • connection tube
    • outlet tube
    • water pipe
    • expansion/reservoir hose (7zap.com)
  • To give you the right part, I need the exact make/model and ideally the VIN. (catcar.info)

Detailed problem analysis

The main issue is ambiguity of identification. The phrase you wrote does not uniquely define:

  1. the vehicle make/model,
  2. the engine code,
  3. or which coolant line you need.

For Renault vehicles, the same general engine family can appear in multiple cars, but the hose routing and part numbers depend on the chassis/model code. Parts catalogs for Renault Mégane II, for example, show the cooling system under a dedicated “Radiator hoses” section, and the catalog is indexed by model code, not just by engine power. (catcar.info)

If your vehicle is a 2006 Renault with 1.9 dCi 120, the hose you need is usually one of these categories:

  • upper radiator hose / radiator inlet tube
  • lower radiator hose / radiator outlet tube
  • water pump inlet hose
  • small bypass/connection hose
  • expansion tank hose
  • sometimes a metal water pipe section rather than a rubber hose. (7zap.com)

This is why asking for “the coolant line” is too broad. On the Mégane II F9Q listing, several distinct cooling pipes are shown separately, so a seller or workshop cannot safely select the part from engine type alone. (7zap.com)

From an engineering perspective, the correct identification method is:

  • first identify the vehicle platform/model,
  • then the engine family/code,
  • then the hose position in the circuit,
  • then match by VIN or OEM catalog.

That avoids ordering the wrong molded hose, which is common because molded coolant hoses have:

  • different bend geometry,
  • different branch tees,
  • different clip/clamp interfaces,
  • and sometimes different sensor or bleed connections.

Current information and trends

For older Renault vehicles, current online parts catalogs still organize coolant parts by model code and subsystem, not by a generic “1.9 dCi 120 hose.” The accessible catalog views for Mégane II show this clearly, with cooling parts grouped under Cooling system → Radiator hoses and multiple separate hose items listed. (catcar.info)

Official Renault press material also confirms that the 1.9 dCi 120 engine was offered in that era on vehicles including the Mégane and Espace, which supports the conclusion that your query most likely refers to a Renault application rather than a unique standalone engine designation. (media.renault.at)


Supporting explanations and details

If you are trying to identify the hose by location, use this quick map:

Hose/line type Typical location Function
Upper radiator hose Top/front of engine to radiator Hot coolant to radiator
Lower radiator hose Bottom radiator to engine/water pump Return coolant
Expansion tank hose Small hose to reservoir Bleed/expansion flow
Heater hose Toward bulkhead/firewall Cabin heater circuit
Pump inlet hose Low/front side of engine Feeds water pump
Bypass/connection hose Around thermostat housing Internal circulation

On Renault parts listings for the Mégane II F9Q, the catalog names include RADIATOR INL TUBE, RADTR OUTLET TUBE, INLET PIPE PUMP, CONNECTION TUBE, OUTLET TUBE, WATER PIPE, and FLEXIBLE RESERVE. (7zap.com)

If by “phot” you meant photo, then the fastest way forward is for you to send:

  • a photo of the engine bay,
  • a photo of the leaking or missing hose,
  • and the vehicle registration/VIN.

Then I can help identify whether it is the upper hose, lower hose, heater hose, or expansion hose.


Ethical and legal aspects

  • Used coolant is an environmental hazard and should not be poured onto the ground or into drains.
  • If the hose is leaking badly, operating the vehicle risks engine overheating and secondary damage.
  • Replacement parts should be matched by VIN/OEM reference to avoid unsafe fitment, especially on molded cooling hoses with branch connections.

Practical guidelines

Please reply with one of these:

  1. Exact vehicle
    Example:

    • Renault Mégane II 1.9 dCi 120, 2006
    • Renault Scénic II 1.9 dCi 120, 2006
    • Renault Espace 1.9 dCi 120, 2006
  2. Which hose you need

    • upper radiator hose
    • lower radiator hose
    • heater hose
    • expansion tank hose
    • thermostat housing hose
  3. Photo or VIN

    • upload a photo of the hose/engine bay
    • or send the last 8 digits of the VIN

Best practice

  • Do not order by “120 dCi” only.
  • Order by VIN or OEM part number.
  • If the old hose is removed, compare:
    • overall shape,
    • branch count,
    • inside diameter,
    • quick-connect ends,
    • bleed nipples/clips.

Possible disclaimers or additional notes

  • I could not verify a unique vehicle called “phot 120 dci 2006.”
  • The most plausible interpretation is “photo” or a typo for a Renault model with 1.9 dCi 120.
  • Without the exact model, giving a part number would be unreliable.

Suggestions for further research

To identify it precisely, the next useful data would be:

  • VIN
  • engine code from the label/plate
  • photo of hose routing
  • where the leak is located:
    • top of radiator,
    • bottom of radiator,
    • near thermostat housing,
    • near firewall,
    • near expansion tank.

Brief summary

Your query is too unclear to name one exact coolant line. For a 2006 Renault 1.9 dCi 120, the cooling system uses several different hoses, and Renault catalogs identify them by exact vehicle/model code, not just engine power. (catcar.info)

If you send me:

  • the exact model, and
  • either a photo or the VIN,

I can help you identify the correct coolant hose/line very accurately.
