Supply-and-fit means one supplier is responsible from collection to handover: engine supply, removal of the old unit, installation, fluids and commissioning. What separates good quotes from bad isn't the headline number — it's the scope: what's removed, what's replaced, what's tested and what happens if something else is found mid-job.

SHY1 Engine Supply & Fit (2.2 SkyActiv-D 150) — One Quote, One Responsibility
A SHY1 supply-and-fit job puts the whole replacement under one quotation: the 2.2-litre SkyActiv-D unit, its removal and installation, and commissioning — for your CX-5 or Mazda 6 (150 PS). This page sets out what the quote should cover, what the fitting plan must show, and how to compare offers so the final bill matches the first one.

What must a SHY1 supply-and-fit quote cover?
The quote should name the engine (a 2.2-litre SkyActiv-D matched to your vehicle's configuration), the removal and installation scope, fluids and consumables, and the commissioning steps. Reviewed records put the code in 150 PS CX-5 applications with grouped Mazda 6 references — so configuration checks come first.
Will a supply-and-fit job suit your CX-5 or Mazda 6?
Records tie SHY1 to the CX-5 (KE/GH, 2012–2017 cited) with grouped Mazda 6 references. Before booking, the workshop should confirm your derivative against the code on the block, your Reg — and check that related components (mounts, pipework, electronics) will match the new unit.
Model context lives at the CX-5 and Mazda 6 hubs; code context at the SHY1 guide.
| Model | Generation / body | Engine | Output | Evidence status |
|---|---|---|---|---|
| Mazda CX-5 | KE/GH (2012–17 cited) | 2.2 SkyActiv-D | Per the SHY1 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 job put right on a 2.2 diesel?
A fit is only as good as the commissioning. The family's known themes — carbon build-up and oil dilution — mean the job should include delivering a clean, correct-running engine, not just a bolted-in one.
The engine directory gives the family context.
Confirm fluids, filters and any required resets are in scope.
Ask how the engine is checked before handover: leaks, pressures, warning lights, road test.
Get the process for extra findings in writing — old engines usually surprise someone.
Supply-and-fit, reconditioned or used — which way for a 150 PS?
Supply-and-fit is the one-invoice route: engine plus labour, one supplier to hold responsible. Reconditioned suits long-term keepers; used is the value play with the right evidence. Choose by what you're protecting — time, money or both.

What must the SHY1 fitting plan include?
Scope: removal, installation, fluids, consumables and commissioning, itemised.
Identification: the engine matches your vehicle — code, configuration and parts.
Checks before handover: leak and pressure checks, warning-light scan, road test.
Contingency: what happens if mounts, pipework or sensors need replacing.
Terms: warranty split between engine and labour, timescales and recovery.
SHY1 supply-and-fit questions
Does supply-and-fit include the engine as well as labour?
It should — that's the point. One quotation covers the unit, removal, installation, fluids and commissioning. If the quote only covers labour, it isn't supply-and-fit.
What happens if extra parts are needed mid-job?
A written contingency makes or breaks a fit quote. Ask how additional parts are authorised and priced before you book, so the final invoice doesn't surprise you.
Is a supply-and-fit engine new?
Usually it's a reconditioned or tested used unit, supplied and fitted. Ask exactly which, and get the same evidence requirements as a standalone purchase.
How long does a fit take?
It varies with the vehicle and the workshop — get the timeline in writing with the quotation, including which days the car is off the road.
