Renault Clio 1.2 16v Engine Replacement Compare Prices & Get Quotes

A Renault Clio 1.2 16v D4F engine replacement typically costs £900-£1,800 supply-only for a rebuilt unit, with used engines from £400 and reconditioned from £800. Total fitted cost adds 6-8 hours of labour at specialist rates (£55-£75/hr) or dealer rates (£100-£150/hr).

• Rebuilt supply-only: £900-£1,800 [ESTIMATED]
• Supply & fit specialist total: £1,300-£2,400
• Main dealer supply & fit: £1,800-£3,000

The most common sign of dephaser pulley failure in the D4F engine is a diesel-like rattle or knocking noise on idle that fades as revs increase. Other symptoms include rough idle, engine judder, and stalling at junctions. The fault is caused by worn oil seals in the dephaser pulley.

• Rattle on idle is the classic symptom - don't ignore it
• Rough idle and stalling are common as the fault worsens
• Replace the dephaser pulley with the timing belt service

This depends on your Clio 1.2 16v's overall condition and market value. For a well-maintained Clio III or IV (worth £2,000-£4,000), a rebuilt engine at £900-£1,800 is viable, especially with the 12-month warranty. For an older Clio II example worth under £1,500, a used engine (£400-£800) or targeted repairs (dephaser, timing belt, coil pack) may be more cost-effective.

• Vehicle worth under £1,500: consider used engine or repair
• Vehicle worth £2,000+: rebuilt engine with warranty is sensible
• Factor in overall condition - bodywork, suspension, interior wear

A Renault Clio 1.2 16v engine replacement typically takes 1-2 working days for a specialist workshop, including removal of the old D4F unit, fitting the replacement, and road testing. Main dealers may quote 2-3 days due to scheduling and OEM parts ordering.

• Supply-only delivery: next-day available across the UK
• Supply & fit: book a slot with your nearest specialist
• Express fitting available in some regions

The D4F 712 was fitted to the Clio II (2001-2005) and produces 75bhp with earlier emissions calibration. The D4F 740 was introduced with the Clio III in 2005 and continued through the Clio IV until 2016, producing 73-75bhp with Euro 4/5 emissions compliance. Both share the same 1,149cc displacement, DOHC 16-valve architecture, and common failure points - dephaser pulley, timing belt, and coil pack.

• D4F 712: Clio II, 75bhp, earlier emissions spec
• D4F 740: Clio III/IV, 73-75bhp, Euro 4/5 compliance
• Both require the same preventative maintenance - timing belt every 5 years/75k

Used engines are cost-effective (£400-£800) but come with unknown service history and no warranty beyond the supplier's standard 30-90 days - risk of the same dephaser, timing belt, or coil pack issues reoccurring. Rebuilt engines (£900-£1,800) include new dephaser pulley, timing belt, water pump, coil pack, piston rings, bearings, and a 12-month unlimited-mileage warranty, offering peace of mind for long-term ownership.

• Used: best for low-budget repairs on lower-value Clios
• Rebuilt: best for long-term ownership (2+ years) and higher-value examples
• Always confirm what components were replaced in a rebuilt unit
