Renault Clio 1.5 dCi Engine Replacement Compare Prices & Get Quotes

A replacement engine for a Renault Clio 1.5 dCi typically costs £900-£2,800 for the supply-only unit. Fitting adds 6-10 hours of labour at £65-£90/hr, bringing the total fitted cost to £1,500-£3,500 at an independent specialist. Dealer pricing is significantly higher.

• Used engine supply: £300-£1,800
• Reconditioned supply: £1,200-£2,400
• Rebuilt supply: £1,800-£3,200

The most common signs are rough idle, hard starting, loss of power, excess smoke from the exhaust, and the engine warning light illuminating. On early K9K models (pre-2011), injector failure is often caused by metal swarf from a failing Delphi high-pressure fuel pump.

• Rough idle and hard starting are early warning signs
• Loss of power and smoke indicate more serious injector wear
• Ignoring injector issues can lead to widespread fuel system contamination

The 1.5 dCi has a "double personality" - some units exceed 300,000 km without issue, while others suffer serious failures. Pre-2011 models are more prone to injector and timing belt issues, while post-2011 models are significantly more robust. Regular maintenance is the key to longevity.

• Pre-2011: known injector and timing belt issues
• Post-2011: considered a reference of robustness
• Regular oil changes and timing belt replacement are essential

It depends on the vehicle's value. Clio II examples are worth £500-£2,000 - a full engine replacement at £1,800-£2,800 may exceed the car's value. Clio III examples (£1,000-£4,000) may justify replacement if the rest of the car is in good condition. Clio IV/Clio V examples with higher values (£3,000-£10,000) generally justify replacement.

• Evaluate the total repair cost vs. the vehicle's current market value
• Consider part-exchange or selling for spares if repair costs exceed 60% of value
• Always get multiple quotes before committing

The K9K 628 produces 75PS (55kW) and was fitted to Clio IV models from 2012-2019. The K9K 638 produces 90PS (66kW) and was also fitted to Clio IV models from 2012-2019. Both share the same 1.5-litre (1,461cc) displacement and the same K9K architecture, but the 638 is the higher-output version.

• K9K 628: 75PS, Clio IV (2012-2019)
• K9K 638: 90PS, Clio IV (2012-2019)
• Both engines share the same architecture and failure points

The 1.5 dCi (K9K) uses a timing belt, not a chain. The belt requires replacement at the manufacturer-recommended interval - typically every 60,000 miles or 5 years, whichever comes sooner. Neglecting the timing belt can lead to catastrophic engine failure if it breaks.

• Timing belt, not chain - scheduled replacement required
• Replacement interval: ~60,000 miles or 5 years
• Belts on 2009-2011 models are particularly prone to premature wear
