Used Ford P100 Heater Matrix

Yes, the Ford P100 pickup truck was fitted with a heater matrix as standard across its production run, as it used a conventional engine-coolant heating system to warm the cabin. The heater matrix sits inside the heater box behind the dashboard and circulates hot coolant from the engine to heat the cab. If your cab heating has stopped working or you are getting a sweet smell or damp footwells, a failed heater matrix is a common culprit on these trucks.

The Ford P100 was built on the Sierra platform and sold in the UK from around 1983 through to 1992, with a notable facelift in 1990 that updated the front end and some interior components. Whether a pre-1990 heater matrix crosses over to a post-1990 truck is not guaranteed, as the facelift may have brought changes to the heater box assembly. We would recommend confirming with the breaker that the part comes from a truck of the same era as yours, quoting your registration so they can match it accurately.

No – engine choice does not affect heater matrix fitment on the P100, as the heater matrix is part of the cab's heating system and is common across the engine range regardless of whether the truck had a 1.6, 2.0 petrol or 2.5 diesel unit fitted. You do not need to specify your engine when searching for this part. Focus instead on the year of your truck and confirm the generation with the breaker.

Trim level does not affect heater matrix fitment on the P100 – the heater box assembly was common across the range regardless of specification. The matrix itself sits in the same location and uses the same connections whether the truck was a base-spec working vehicle or a higher-grade example. You may notice minor differences in surrounding dashboard furniture when dismantling, but the matrix itself should be the same part.

This question spans the 1990 facelift, which is the key boundary to be aware of on the P100 range. It is possible there were changes to the heater box or matrix connections around this time, so a straight swap from a pre-1990 truck to a post-1990 one is not something we can confirm as guaranteed. We would strongly recommend checking with the breaker directly, quoting both your registration and the donor vehicle's details, so they can compare the parts before you commit.

Give the breaker your full registration number so they can pinpoint the exact year of your truck, and let them know whether it is a pre-1990 or post-1990 vehicle if you already know. You do not need to mention the engine size, as this does not affect which matrix you need. A good breaker will ideally cross-reference the part from a donor truck of the same year to give you the best chance of a clean fit.
