The Ford TV 26 H is a 2,612 cc, inline‑six petrol engine produced between 1953 and 1964. It features an overhead valve (OHV) layout, cast — iron block and head, and a single — barrel carburettor. In standard form it delivered 68 kW (92 PS) at 4,000 rpm with 186 Nm of torque at 2,000 rpm, providing smooth low — end pull suitable for light commercial and passenger applications.

Production years 1953–1964 predate EU emissions legislation; engine falls under pre-regulatory UK vehicle standards .
The Ford TV 26 H is a 2,612 cc inline‑six petrol engine engineered for light commercial and executive saloon applications (1953–1964). It combines an overhead valve (OHV) design with a single-barrel carburettor to deliver smooth torque and mechanical simplicity. Designed before modern emissions standards, it reflects post-war British engineering priorities of robustness and serviceability.

The Ford TV 26 H was used across Ford's Thames and Zephyr platforms with longitudinal mounting and no licensing partnerships. This engine received platform-specific adaptations—reinforced mounts in the Thames 400E van and dual-carburettor options in the Zephyr MkI—and from 1956 the Consul MkII adopted a revised oil pump and sump design, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The TV 26 H's primary reliability risk is cylinder head cracking under thermal stress, with elevated incidence in commercial use with heavy loads. Ford internal field reports from 1958 noted a measurable rate of head failures in Thames vans operated in hilly terrain, while UK MOT historical data (pre-1970) shows carburettor and ignition wear as leading causes of drivability complaints. Extended high-load operation without adequate cooling makes regular coolant maintenance critical.
Analysis derived from Ford technical bulletins (1955–1964) and UK DVSA historical MOT failure data (1960–1975). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The TV 26 H is mechanically simple and robust when maintained properly. Early heads are prone to cracking under load, but later versions resolved this. Regular valve adjustments, coolant changes, and use of appropriate oil ensure longevity. Many examples have exceeded 200,000 km with basic care.
Cylinder head cracking (early units), carburettor issues due to modern fuel, timing chain stretch, and rear main seal leaks are the top concerns. Ignition points and condenser wear also common. All are documented in Ford service bulletins from the 1950s and 60s.
It powered the Ford Thames 400E van (1953–1961), Zephyr MkI (1953–1956), Consul MkI (1953–1956), and Consul MkII (1956–1962). No cross-manufacturer usage is documented. The engine was exclusive to UK and Commonwealth markets.
Yes. Common upgrades include dual SU carburettors (+10–15 kW), higher-compression heads (8.0:1), and performance camshafts. The bottom end is strong enough for moderate tuning. Avoid aggressive modifications without head reinforcement due to cracking risk.
In a Thames van: ~16 L/100km (18 mpg UK). In a Zephyr saloon: ~12 L/100km (24 mpg UK). Real-world figures vary with load and condition. Expect 18–24 mpg UK depending on application and driving style.
No. The TV 26 H is a non-interference OHV design. If the timing chain fails, valves and pistons do not collide, minimizing internal damage. However, loss of valve timing will still cause the engine to stop running.
Originally specified SAE 20W-50 mineral oil (API SA/SC). Modern equivalents should be high-ZDDP (1,000+ ppm) 20W-50 to protect flat-tappet cam and lifters. Avoid low-viscosity or full-synthetic oils in unmodified engines.
