Fitment Guide & VIN Verification

Selecting the correct automotive spare part requires precise vehicle identification. Even small differences in engine type, production month, trim level, or electrical configuration may result in incompatibility.

This guide explains how to verify compatibility before placing your order and outlines your responsibilities when purchasing from Zefix.


1. WHY COMPATIBILITY MATTERS

Automotive manufacturers frequently introduce changes within the same model year. Two vehicles that appear identical may have different:

  • Engine configurations
  • Transmission types
  • Sensor connectors
  • Brake system specifications
  • Mounting dimensions

For this reason, selecting a part based solely on vehicle brand and model name is insufficient in many cases.


2. INFORMATION REQUIRED BEFORE ORDERING

To ensure accurate compatibility, customers should confirm:

  • Vehicle make
  • Model
  • Year of manufacture
  • Engine size and engine code
  • Transmission type (manual / automatic)
  • Trim or variant (if applicable)
  • VIN (Vehicle Identification Number)

Providing complete and accurate information significantly reduces the risk of ordering an incompatible component.


3. WHAT IS A VIN AND WHY IT IS IMPORTANT

The Vehicle Identification Number (VIN) is a unique 17-character code assigned to every vehicle.

The VIN allows precise identification of:

  • Manufacturer
  • Production plant
  • Engine specification
  • Model variant
  • Production sequence

The VIN is typically located:

  • On the dashboard (visible through windshield)
  • On the driver’s side door frame
  • On vehicle registration documents

When available, providing the VIN at checkout allows more accurate part verification.


4. RESPONSIBILITY FOR PART SELECTION

Zefix provides compatibility information based on manufacturer data and supplier references. However, final responsibility for part selection rests with the Customer.

If VIN or complete vehicle details are not provided at checkout, Zefix shall not be liable for incompatibility claims.

Compatibility statements on product pages are intended as guidance and do not replace professional verification.


5. ELECTRICAL AND ELECTRONIC COMPONENTS

Electrical components such as:

  • Sensors
  • Control modules
  • Alternators
  • Starter motors
  • Engine management components

may have minor connector differences or calibration variations between production batches.

Customers must ensure full compatibility before installation.

Electrical parts are non-returnable once connected to a power source.


6. ENGINE AND MECHANICAL COMPONENTS

Engine components, cooling systems, and drivetrain parts may differ depending on:

  • Engine displacement
  • Turbo or non-turbo configuration
  • Production month
  • Regional manufacturing variations

Visual similarity does not guarantee compatibility.

Professional mechanical consultation is strongly recommended prior to installation.


7. SPECIAL-ORDER PRODUCTS

Where a Product is specially sourced based on Customer-provided information, the accuracy of the supplied vehicle details is critical.

Special-order Products are non-refundable once procurement has commenced.

Incorrect or incomplete vehicle information may result in incompatibility for which Zefix shall not be responsible.


8. WHEN IN DOUBT

If uncertain about compatibility, customers are encouraged to:

  • Consult a qualified mechanic;
  • Cross-reference part numbers;
  • Provide full VIN information prior to ordering.

Zefix may assist with reference checks where sufficient vehicle data is provided, but such assistance does not constitute a guarantee of fitment.


9. INSPECTION BEFORE INSTALLATION

Customers must inspect the Product prior to installation.

Once a Product is installed, mounted, or connected, it becomes ineligible for return except under approved warranty conditions.

Testing fitment without installation is strongly recommended before final mounting.
