Kia Avella Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Kia Avella replacement engines. Whether addressing G-series timing belt wear in early S1 models or D3EA diesel head cracking in fleet variants, we provide direct OEM-spec solutions across the full Avella series.
Kia Avella Replacement Engines
The Kia Avella spanned two core generations: S1 (1994-2000) with G10B/G13B/G15B petrol and D3EA diesel engines, and S2 (2000-2002) introducing B5A/G4CN petrol and D4EA diesel units. All G-series engines share a timing belt-driven SOHC design prone to tensioner failure after 90,000 miles, while D3EA/D4EA diesels suffer from cylinder head warping under UK stop-start conditions. Kia Technical Bulletin KTIS-98-07 issued revised head gasket specs (OEM 21111-37150) for all S1 diesel variants due to recurring overheating issues.
Kia Avella Models & Engines Codes
Engine families span all Avella trims within each generation, with shared components creating consistent failure points across variants.
- G10B/G10A: 1.0L petrol (S1, 1994-2000) - Avella LX/GL/Urban; crankshaft wear common in high-mileage units
- G13B/G15B/B5A: 1.3L-1.5L petrol (S1/S2, 1994-2002) - GL/EX/Sport trims; timing belt and water pump failures
- G4CN: 1.6L petrol (S2, 2000-2002) - SRX/Limited; valve guide seal leakage in all applications
- D3EA/D4EA: 1.5L-1.6L diesel (S1/S2, 1995-2002) - LD/CD/TD fleet models; head cracking due to thermal stress
All petrol engines use identical distributor-based ignition (OEM 27310-37001), while diesel variants share injector pump design (Bosch VP37, OEM 26100-D3001), making cross-variant diagnosis and rebuild protocols consistent across the Avella series.
Buy Used and Second-Hand Kia Avella Engines
Used Avella engines carry high risk due to shared mechanical weaknesses across all variants. Reconditioned units with updated components are strongly recommended for long-term reliability.
- Reconditioned G-series: Includes new timing belt kit (OEM 25311-37701) and water pump
- Remanufactured D3EA/D4EA: Features upgraded cylinder head (OEM 21100-D3001) and reinforced head bolts
- Full-series compatibility: All rebuilt units fit Avella LX through Limited trims (S1/S2 chassis)
Engine Finders only partners with UK workshops following Kia Avella Series Rebuild Standard KRS-01, ensuring identical quality across petrol and diesel applications regardless of original trim level.
