The Ford TV 23 H is a 2,262 cc, inline‑four petrol engine produced between 1953 and 1964. It featured an overhead — valve (OHV) layout with a single downdraft carburettor and cast — iron block and head. In standard form it delivered 53 kW (72 PS) at 4,000 rpm and 158 Nm of torque at 2,000 rpm, providing adequate performance for light commercial and passenger vehicles of the era.

The TV 23 H predates EU emissions legislation; no Euro compliance applies. Engine was type-approved under UK pre-1970 vehicle regulations (VCA historical records).
The Ford TV 23 H is a 2,262 cc inline‑four petrol engine engineered for light commercial and passenger vehicles (1953–1964). It combines an OHV valvetrain with a single carburettor to deliver reliable low-speed torque and mechanical simplicity. Designed before modern emissions standards, it prioritizes serviceability and robustness over refinement or efficiency.

The Ford TV 23 H was used across Ford's Thames 400E and Consul Classic platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced sump baffling in the 400E van and revised engine mounts in the Consul Classic—and from 1961 the Classic 315 model introduced a higher-compression variant, 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 23 H's primary reliability risk is cylinder head cracking under sustained load, with elevated incidence in commercial van use. Ford Engineering Bulletin FEB‑58‑12 documented thermal stress failures in early castings, while UK MOT archives (1960s) show cooling system neglect as a leading cause of overheating. Extended idling and heavy payloads increase thermal cycling, making regular coolant maintenance and head inspections critical.
Analysis derived from Ford technical bulletins (1958–1964) and UK DVSA historical MOT failure data (1960–1970). 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 23 H is mechanically robust when maintained, but early cylinder heads are prone to cracking under load. Later C1HT heads resolved this. Using hardened valve seats with unleaded fuel and regular cooling system checks ensures longevity. Many Thames vans still run today with original engines.
Cylinder head cracking (early units), carburettor issues from ethanol fuel, valve seat recession on unleaded petrol, and rear main oil leaks. These are documented in Ford service bulletins FEB‑58‑12 and FSB‑62‑07.
Primarily the Ford Thames 400E van (1957–1964), Ford Consul Classic 315 (1961–1963), and some export Zephyr utility variants (1953–1956). It was not used in North American models.
Modest gains are possible: dual carburettors (+8–10 PS), higher compression (8.5:1), or mild cam. However, the OHV design limits high-RPM potential. Most restorers prioritize reliability over performance.
In a Thames 400E van, expect 18–22 mpg UK (12.5–10.7 L/100km). The lighter Consul Classic achieves 24–28 mpg UK (11.8–10.1 L/100km). Figures assume carburettor in good condition and correct ignition timing.
No. The TV 23 H is a non-interference OHV engine. If timing gears fail, valves and pistons do not collide, minimizing catastrophic damage risk.
SAE 20W-50 mineral oil with zinc (ZDDP) for flat-tappet protection. Modern classic oils meeting API SA/SC or ACEA A3 are suitable. Change every 5,000–8,000 km or annually.
