Supply-and-fit puts one supplier in charge from collection to handover: the engine, the removal, the installation and the commissioning. The headline price is only half the story — the scope is what protects you. Reviewed records put SHY4 in a 175 PS CX-5 context, so configuration checks come first.

SHY4 Engine Supply & Fit (2.2 SkyActiv-D 175) — One Quotation, Whole Job
A SHY4 supply-and-fit job covers the 2.2-litre SkyActiv-D unit for your CX-5 or Mazda 6 (175 PS), its removal and installation, and commissioning — in one quotation. This page explains what belongs in that quote and how to compare them so the price you agree is the price you pay.

What should the SHY4 supply-and-fit quote itemise?
The engine (correctly matched 2.2 SkyActiv-D), removal and installation scope, fluids and consumables, and commissioning checks. Configuration is confirmed against your vehicle first — the code is recorded in 175 PS CX-5 applications with grouped Mazda 6 references.
Will a fit job suit your CX-5 or Mazda 6?
Records link SHY4 to the CX-5 (KE/GH, 2012–2017 cited) with grouped Mazda 6 references. The workshop should confirm your derivative and check that mounts, pipework and electronics will match the replacement unit before the job is booked.
CX-5, Mazda 6 and the SHY4 guide for the technical context.
| Model | Generation / body | Engine | Output | Evidence status |
|---|---|---|---|---|
| Mazda CX-5 | KE/GH (2012–17 cited) | 2.2 SkyActiv-D | Per the SHY4 record | Reviewed European OEM-linked record |
| Mazda Mazda 6 | Grouped references | 2.2 SkyActiv-D | Shared context | Grouped record — not a universal fitment claim |
| UK derivatives | — | — | — | Still to confirm — check the code against your Reg and Mazda EPC |
What should the fitting put right on a 2.2?
Delivery plus commissioning is the standard you're paying for — including how the known family themes (carbon build-up, oil dilution) are accounted for in the supplied unit.
Family context: engine directory.
Fluids, filters and resets listed in scope.
Pre-handover checks: leaks, pressures, warning lights, road test.
Written process for anything found during the job.
Supply-and-fit, reconditioned or used — which way for 175 PS?
One invoice and one responsible supplier is the supply-and-fit promise; reconditioned suits long keepers; used is the value option with strong evidence.

SHY4 supply-and-fit questions
Is the engine included in the price?
In a genuine supply-and-fit quote, yes — engine plus labour. If the quote is labour-only, it isn't supply-and-fit.
Who warranties what?
Ask for the split in writing: engine warranty, labour warranty and what each covers. That clarity is worth more than a rounded number.
Can the job be done at my location?
Some suppliers offer mobile or partner-workshop options — ask early, and check recovery arrangements if the car isn't drivable.
What if the car needs more than the engine?
Get the contingency process up front: how extra work is authorised, priced and timed. Old engines rarely fail politely.
