Fiat Mobi Engine ReplacementCompare Prices & Save

Yes, Fiat Mobi engines are available in the UK through specialist import networks and our marketplace of vetted suppliers who source Brazilian-spec units. While the Mobi was never sold officially in the UK, our network specialises in importing Fire Evo and Firefly engines with full warranty coverage.

• Engines sourced from Brazil or European breakers with Mobi fitment
• Typical lead time 7-14 days depending on engine code and variant
• All supplied engines include 12-month unlimited mileage warranty
• Delivery arranged to your chosen UK garage or address

Typical UK rebuilt Fiat Mobi engine prices range from £1,200-£3,200 supply-only, depending on whether you need Fire Evo or Firefly specification and current import logistics. Firefly engines often carry a small premium due to lower UK availability.

• Fire Evo rebuilt: £1,200-£2,800 typical range
• Firefly rebuilt: £1,400-£3,200 typical range
• Supply & fit adds £450-£850 depending on garage location
• Flex-fuel variants may carry additional sourcing costs

For UK-imported Mobis valued £4,000-£8,000, engine replacement is often worthwhile given the vehicle's low purchase price and running costs. However, obtain multiple quotes and factor in import logistics before committing.

• Replacement cost typically 25-40% of a well-maintained Mobi's UK value
• Rebuilt engine with warranty offers better long-term value than used unit
• Consider total vehicle condition: suspension, bodywork, interior before deciding
• Our network can provide valuation guidance alongside engine quotes

The Fiat Mobi and Uno share the 327 platform and many Fire Evo components, but engine swaps require careful verification of ECU, wiring loom and ancillary compatibility. Not all Uno engines are direct fits.

• Fire Evo block architecture is shared but mounting points may differ
• ECU calibration and sensor layouts often variant-specific
• Ancillary components (alternator, AC compressor) may not interchange
• Always confirm exact engine code compatibility before purchasing

Fire Evo is a 4-cylinder 8-valve design with timing belt; Firefly is a 3-cylinder 6-valve design with timing chain. They share displacement but differ in layout, ECU, and failure patterns.

• Fire Evo: 4-cyl, timing belt, 73-75hp, simpler design
• Firefly: 3-cyl, timing chain, 75-77hp, better fuel economy
• Different engine mounts and ancillary routing
• Firefly engines command premium due to lower UK availability

Fire Evo engines use a timing belt requiring replacement every 60k miles; Firefly engines use a timing chain with tensioner that can wear from 50k miles. Both require proactive maintenance to avoid failure.

• Fire Evo: belt replacement critical at 60k miles to prevent valve damage
• Firefly: chain doesn't need routine replacement but tensioner can fail
• Ignoring either leads to catastrophic engine damage requiring replacement
• Our rebuilt engines include upgraded timing components as standard

Typical turnaround is 7-14 days for engine sourcing plus 1-2 days for fitment at your chosen garage. Import logistics can extend lead times for Firefly or flex-fuel units.

• Engine sourcing: 3-10 days depending on code and stock
• Delivery to UK garage: 1-3 days domestic, longer for import units
• Fitment and commissioning: 1-2 working days at specialist garage
• Total timeline typically 7-14 days from quote acceptance

Yes, every Fiat Mobi engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty covering parts and labour at any UK garage, with optional extended coverage available.

• Standard warranty: 12 months, unlimited mileage, UK-wide coverage
• Covers manufacturing defects and premature component failure
• Extended warranty options available at point of quote
• Warranty valid regardless of which network supplier fulfils your order

Fiat specifies 5W-30 fully synthetic oil meeting Fiat 9.55535-S1 for Firefly engines; Fire Evo units use 5W-40 semi-synthetic meeting Fiat 9.55535-G1. Always confirm spec for your exact engine code.

• Firefly: 5W-30 fully synthetic, approx. 3.2L capacity with filter
• Fire Evo: 5W-40 semi-synthetic, approx. 3.0L capacity with filter
• Use oil meeting exact Fiat specification to maintain warranty
• Oil change interval: 10k miles or 12 months whichever comes first

The engine code stamp is located on the cylinder block near the oil filter housing; the vehicle VIN plate on the driver's door pillar also references the original engine specification for verification.

• Block stamp: visible near oil filter, format like "312B2000" or "GSE4G10"
• VIN plate: driver's door pillar, cross-reference with Fiat database
• Registration lookup via our tool instantly identifies correct engine code
• Always verify code before ordering replacement to ensure compatibility
