Which models use the 3.2?

Code guide: P5-AT; model: BT-50.
| Model | Engine | Evidence status |

| Older P4-AT era | Earlier Duratorq generation | Different code family — not a match |
What goes wrong on a 3.2 Duratorq?
Records flag timing chain and oil-pump drive wear and injector issues.
Family context: engine directory.
Chain: cold-start rattle and chain-work history matter on hard-worked engines.
Injectors: test data beats descriptions — diagnose before condemning.
Duty history: towing and loads wear bearings, turbo and cooling.
Used, reconditioned or supply-and-fit — which way for a 3.2?
Downtime drives the decision: tested used with strong evidence gets you working fastest; reconditioned trades cost for renewed internals; supply-and-fit gives one quote and one responsibility.

3.2-litre Mazda questions
Is P5-AT the same as P4-AT?
No — different Duratorq generations. Match the physical marking on your engine.
What should I check on a used 3.2?
Donor Reg and duty history, compression and oil-pressure evidence, plus the components list. Ask about chain and injector history.
Do supply-and-fit quotes cover pickups?
Many suppliers handle commercial vehicles — ask about recovery, timescales and commercial-use warranty terms.
What evidence should a reconditioned 3.2 come with?
Machining and measurement records, replaced-parts lists, assembly and test results, and the identity of the actual engine.
