Ford P100 Glow Plugs Replacement Parts

Yes, the Ford P100 pickup (produced from 1983 to 1992) was powered exclusively by diesel engines throughout its production run, so every P100 has glow plugs – there is no petrol variant to worry about. The most common engine was the 2.5-litre naturally aspirated diesel, with a turbocharged 2.5 TD version also available, and glow plug specification can differ between these two units. Always confirm which engine you have before ordering.

The P100 ran as a single generation from 1983 to 1992, with a notable facelift arriving around 1987 that brought various updates, but the 2.5-litre diesel engine family carried across both phases of production. The glow plug specification is primarily tied to the engine code rather than the model year, so plugs from either side of the 1987 facelift may well interchange if the engine code matches – but confirm this with the breaker against your registration before buying, as ancillary and component changes can occur mid-production without obvious external signs.

No – trim level has no bearing on glow plug fitment whatsoever. Glow plugs are determined entirely by the engine code and fuel system, not by whether your truck is a base-spec or higher-grade variant. Focus on supplying the breaker with your engine code (found on your V5 or via a VIN check) rather than worrying about trim designation.

Quite possibly yes – the naturally aspirated 2.5-litre diesel and the turbocharged 2.5 TD variant can have different glow plug requirements due to differences in combustion chamber design and injection system setup. This is exactly why the engine code is the most important detail to have to hand when sourcing used parts. Give your engine code to the breaker and they can confirm whether the plugs from a specific donor vehicle match your application.

The P100's 2.5-litre diesel is a four-cylinder engine, so it has four glow plugs in total, one per cylinder. Breakers will often sell these individually from a dismantled vehicle, but it is generally advisable to replace all four at once, as a plug from the same donor engine will have matching wear characteristics. Ask the breaker whether they can supply a matched set of four from a single vehicle for the best result.

The P100 did share its 2.5-litre diesel engine family with other Ford commercial vehicles of the period, including certain Transit variants, and in principle glow plugs from an engine with an identical engine code should be interchangeable. However, engine codes must match exactly, as there were variations in the diesel units across different applications and model years. Confirm the donor vehicle's engine code with the breaker against your own before purchasing – do not assume compatibility purely on the basis of similar displacement or vehicle era.
