Parts for your 2018 Ford Everest-Ignition coils

2018 Ford Everest ignition coils — are they even a thing?

Short answer: no, the 2018 Ford Everest does not use ignition coils. The 2018 Australian and New Zealand market Everest is powered by diesel engines (notably the 3.2‑litre Duratorq TDCi inline‑five, the 2.0‑litre Bi‑Turbo diesel followed for MY2019). Diesel engines rely on compression ignition rather than spark ignition, so they don’t have spark plugs or ignition coils. This is confirmed by Ford service literature for the 3.2L Duratorq TDCi (Workshop Manual, Engine — Diesel, 303 sections), the 2018 Everest Owner’s Manual references to a glow plug indicator and diesel-specific starting procedure, and the Ford Australia MY2018 Everest specification sheets, which list diesel only.

Here’s why that matters: ignition coils are a petrol‑engine part that step up voltage to fire spark plugs. A 2018 Everest diesel instead uses high‑pressure common‑rail fuel injection, controlled by the PCM, with assistance from glow plugs for cold starts. So if someone’s chasing a “coil pack” fault on a 2018 Everest diesel, they’re barking up the wrong tree.

Common issues that can feel like a petrol misfire but are diesel‑specific include:

• Hard cold starts or rough idle when cold — often glow plug or glow plug relay issues.
• Surging, rough running, or “miss” under load — may point to a clogged fuel filter, air leaks on the supply side, injector wear, EGR sticking, boost leaks, or sensor faults (MAF/MAP).
• Low power or excessive smoke — check turbo/charge‑air hoses, DPF soot loading/regen strategy, and fuel quality (water‑in‑fuel).

Good servicing habits for a 2018 Everest diesel: replace the fuel filter at the recommended interval (and sooner if contaminated fuel is suspected), drain the water separator when prompted, keep the battery in top nick so the glow system performs properly, and use quality diesel with the correct cetane rating. If cold starting degrades or a glow plug lamp stays on, test glow plug resistance and the control module before replacement. For persistent rough running, get the fault codes read and run injector correction and leak‑back tests per the Ford Workshop Manual rather than throwing parts at it.

Bottom line: ignition coils aren’t fitted to the 2018 Everest diesel. Anyone quoting coil packs for this vehicle is likely thinking of a petrol Ford, not an Everest of this year.

FAQs

Does a 2018 Ford Everest have ignition coils?
No. The 2018 Everest sold in Australia and New Zealand is diesel‑only, and diesel engines don’t use spark ignition. Ford workshop and owner’s manuals for the 3.2L Duratorq TDCi describe glow plugs and common‑rail injection, with no ignition coils listed.

What causes a misfire‑like feeling on a 2018 Everest if there are no coils?
On a diesel Everest, rough running is more commonly caused by fuel filter restriction, injector issues, air leaks, EGR sticking, boost hose leaks, or sensor faults (MAF/MAP). Read DTCs, check fuel quality, and pressure‑test the charge‑air system before replacing parts.

Does the 2018 Everest have glow plugs, and when should they be replaced?
Yes. Glow plugs aid cold starts. Replace only if testing shows a failure or the glow plug warning persists and diagnostics point to the plugs or control module. Use the correct spec plugs and proper torque to avoid damage.
