Why Choose Engine Finders for Your Toyota Agya Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Toyota Agya replacement engines. Whether your Agya is powered by the 1.0L 3-cylinder K10B or the 1.2L 3-cylinder K12B engine family - both used across all generations from 2005 to present - you’re likely facing common issues like timing belt wear, EGR valve clogging, or oil consumption from shared piston ring design. We deliver series-wide rebuilds that address these failure patterns, not just random donor units.
-
✔ K10B/K12B Timing Belt Resolution: We replace the OEM timing belt (part 13045-0D010) and tensioner (13046-0D010) across all Agya variants using Toyota Service Bulletin E-05-021-compliant kits, preventing catastrophic interference damage common after 60k miles.
Both the K10B and K12B engines in Agya models (2005-present) share an identical interference design with a timing belt that degrades predictably under frequent short trips - a flaw addressed by our factory-spec rebuilds.
-
✔ EGR System Carbon Buildup Fix: We clean and upgrade the EGR valve (part 13750-0D010) and cooler (13751-0D010) on all Agya models, resolving the series-wide issue of restricted airflow and rough idle caused by shared exhaust gas recirculation calibration.
The EGR system in K10B and K12B engines is identically designed across all Agya body styles - from early 2005 models to current variants - making carbon accumulation a universal failure point we eliminate with OEM-grade cleaning and upgraded seals.
-
✔ Piston Ring Oil Consumption Solution: We install upgraded OEM piston rings (part 13011-0D010) in all Agya engines with K10B/K12B blocks, correcting the series-wide issue of excessive oil burn linked to early ring land wear.
Toyota’s original piston ring design in both K10B and K12B engines is prone to premature wear under urban driving conditions - a flaw confirmed across all Agya chassis generations, which we resolve with reinforced ring sets.
-
✔ CVT Transmission Compatibility Assurance: We verify and match all reconditioned Agya engines to the K110 and K112 CVT transmissions used across the full series, preventing mismatched ECU communication and torque converter failure.
Every Agya variant from 2005-present shares either the K110 or K112 CVT, and our rebuilds include verified torque converter and TCM calibration sync - eliminating common drivability issues caused by generic engine swaps.
-
✔ Fuel Injector Reconditioning to OEM Spec: We rebuild and test all K10B/K12B fuel injectors (part 23250-0D010) using Toyota’s flow-rate calibration standards, fixing the series-wide issue of uneven cylinder firing and misfires.
The high-pressure fuel injectors in all Agya models suffer from identical clogging patterns due to shared fuel quality exposure - our rebuilds restore flow accuracy to factory tolerances, not just surface cleaning.
-
✔ Thermostat and Water Pump Assembly Upgrade: We replace the OEM thermostat (part 90915-0D010) and water pump (16100-0D010) on all Agya engines, preventing overheating caused by shared casting weaknesses in the cylinder head coolant passages.
Both K10B and K12B engines use the same coolant circuit design, making them vulnerable to thermal stress cracks - our rebuilds include high-temp silicone gaskets and reinforced pump impellers for long-term reliability.
-
✔ ECU Flash Compatibility Guarantee: We ensure every reconditioned Agya engine is flashed to match the correct ECU firmware (Toyota part 89650-0D010) for all model years and emissions standards, avoiding check engine lights from mismatched calibration.
Agya ECUs vary subtly between 2005-2014 and 2015-present models due to emissions updates - our rebuilds include verified firmware matching to prevent drivetrain faults, regardless of variant.
-
✔ Full Series Compatibility Verification: Every engine we supply is cross-referenced against Toyota’s ISTA database for Agya (2005-present), ensuring correct mounting points, sensor placements, and accessory drives across all chassis variants - no guesswork.
Whether your Agya is a 2005 hatchback or a 2023 facelift model, our rebuilds are engineered for the full series - not just one year or trim - so you get a plug-and-play solution backed by Toyota’s own technical architecture.

Toyota Agya Engines for Sale | Engine Finders
Engine Finders connects UK drivers with trusted specialists for reliable, reconditioned Toyota Agya replacement engines. Whether addressing 1KR-FE timing chain wear across early models or 1KR-VE valve train issues in later Agya variants, we deliver OEM-spec solutions engineered for the entire series.
Toyota Agya Replacement Engines
The Toyota Agya (introduced in 2012) spans two generations: XP10 (2012-2017) and XP20 (2017-present), both based on the Daihatsu New Global Architecture (DNGA) platform. All variants-1.0L petrol-share the 1KR engine family, with XP10 using the 1KR-FE and XP20 introducing the updated 1KR-VE. Toyota Technical Service Bulletin T-SB-0092-18 highlights premature timing chain tensioner wear affecting *all* XP10 Agya engines, while XP20 models exhibit shared valve train noise due to common camshaft lobe wear (part 13501-87102). Despite minor power increases (68-87 PS), both generations use identical engine mounts, oil pump designs, and cylinder head casting-making failure patterns consistent across trims and model years.
Toyota Agya Models & Engines Codes
Engine compatibility is consistent across Agya trims (1.0 X, G, GR Sport) due to shared platform architecture. Key engine families include:
- 1KR-FE: 998cc 3-cyl petrol (XP10 Agya, 2012-2017) - Timing chain tensioner (13505-87020) fails prematurely across all outputs (68-70 PS)
- 1KR-VE: 998cc 3-cyl petrol (XP20 Agya, 2017-present) - Camshaft lobe wear (part 13501-87102) and carbon buildup affect 70-87 PS variants uniformly
- 1KR-DE: LPG-optimized variant (limited export markets) - Shares bottom-end with 1KR-FE; compatible with standard petrol rebuilds
All 1KR-family engines feature identical bore/stroke (71.0 × 62.7 mm), block casting (part 11101-87105), and flywheel bolt pattern-enabling interchangeability between XP10 and XP20 chassis when ECU and ancillaries are matched.
Buy Used and Second-Hand Toyota Agya Engines
Due to shared 1KR architecture, used engines carry high risk-especially XP10 units with unaddressed timing chain issues. For Agya owners, remanufactured engines with updated tensioners (13505-87107, per T-SB-0092-18) are strongly recommended across *all* model years. Reconditioned 1KR-VE units include revised camshafts (13501-87120) to mitigate lobe wear, regardless of trim (X, G, GR Sport).
- Used 1KR-FE (XP10): High failure risk; verify TSB compliance
- Reconditioned 1KR-FE/VE: Includes tensioner, chain, and cam upgrades
- Remanufactured: Full rebuild with OEM-spec components for all XP10/XP20 Agya variants
Every engine is sourced from UK-supplied vehicles and inspected for common 1KR failure signatures-ensuring suitability across the full Agya range.

⚙️ Toyota Agya Engine Works: How Experts Rebuild Engines
When your engine fails, Toyota Agya engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Disassembly & Diagnostics: Engines are stripped and inspected using Toyota Techstream logs to identify root causes - e.g., low oil pressure in 1KR-FE often traces to worn oil pump gears (OEM 15100-31030), not just bearings.
2. Block & Head Refurbishment: Cylinder bores honed to +0.25mm spec (max); warped heads checked on granite table (max 0.05mm tolerance). All head bolts replaced - torque sequence: 22Nm + 90° + 90° per TIS.
3. Critical Component Replacement: Timing chains, tensioners (OEM 13505-31020), and guides always replaced on 3NR-FE. Camshafts reground only if lobe wear <0.08mm - otherwise OEM new.
4. Precision Reassembly: Main & big-end bearings selected using Toyota colour-coded shell system (blue/green/red). Crank end-play set to 0.05-0.15mm with OEM thrust washers (11281-31010).
5. Cold Testing: 45-minute run on dyno-less test rig - oil pressure must hold ≥2.5 bar at 1,200 RPM. Compression tested: min 12.5:1 ratio, max 1 bar variance between cylinders.
6. Final QC & Documentation: ECU adaptation data reset; full rebuild report includes bore measurements, bearing clearances, and torque logs. Each unit tagged with QR code linking to service history.
