The CADILLAC K3-VE is a 1,298 cc inline-three naturally aspirated petrol engine engineered for compact city cars (1998–2007). It combines SOHC architecture with variable valve timing to deliver responsive throttle response and high fuel efficiency. Designed to meet Euro 3 standards, it balances urban drivability with low CO₂ emissions.

The CADILLAC K3-VE was used across Opel/Vauxhall platforms with transverse mounting and no direct Cadillac-branded applications. This engine received platform-specific adaptations-revised cooling routing in the Agila A and shorter accessory drives in the Karle-and from 2007 the facelifted Agila A adopted the A13NET with revised VVT system, creating 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The K3-VE is generally robust, but early models (1998–2001) are prone to timing tensioner wear. Later revisions (post-2001) with improved spring design significantly enhance longevity. Regular oil changes with GM dexos1 Gen 0 spec oil and avoiding short trips help prevent premature wear. Well-maintained engines often exceed 180,000 km.
Key issues include timing belt tensioner wear (pre-2001), coolant leaks from plastic thermostat housing, valve cover oil leaks, and VVT solenoid clogging. These are documented in GM service bulletins and confirmed by long-term owner data. The tensioner issue is particularly critical due to spring fatigue in early units.
The K3-VE was not used in any Cadillac-branded vehicles. It was developed by Daihatsu and used in Agila A and Karl models (1998-2007). It replaced the K3-DE-based prototypes and was later superseded by the A13NET with direct injection. All applications meet Euro 3 emissions standards.
Aftermarket ECU tuning is common on the K3-VE platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In an Agila A, combined consumption is ~5.6 L/100km (~50 mpg UK). Highway driving yields ~5.0 L/100km (~56 mpg UK), while city use can reach 7.0 L/100km (~40 mpg UK). Real-world figures depend on driving style, but the engine is highly efficient for a 1.3L naturally aspirated triple of its era.
No. The K3-VE uses a non-interference design. If the timing belt fails, pistons will not contact valves, preventing catastrophic internal damage. However, belt replacement is still recommended at 150,000 km as a preventative measure to maintain valve timing accuracy.
GM specifies 5W-30 oil meeting GM dexos1 Gen 0 spec. Use high-quality synthetic oil and change every 15,000 km or annually. Proper oil selection is critical to protect the VVT system and timing belt, especially in pre-2001 engines. Avoid low-detergent or non-synthetic oils.
