Chrysler 300 Engine ReplacementCompare Quotes from UK Specialists

A rebuilt Chrysler 300 / 300C engine typically costs between £1,400 and £3,200 for supply only, depending on the engine code. Adding professional supply and fit installation generally adds £600 to £1,200 to the total bill.

• 3.0L CRD (EXL) rebuilt units average £1,400 to £2,600.
• 5.7L HEMI (EZB) rebuilt units average £1,800 to £3,200.
• Supply and fit service includes labour, fluids, and a unified warranty.
• Prices exclude ancillary parts like new DPFs or EGR valves if required.

The most frequent catastrophic failures are timing chain stretch in the 3.0L CRD (EXL) diesel and hydraulic lifter tick leading to camshaft wear in the 5.7L HEMI (EZB) petrol. Both issues are well-documented and directly addressed in our rebuilt units.

• EXL timing chains often fail between 80,000 and 100,000 miles.
• EZB lifter tick is caused by oiling issues and collapsed lifters.
• Ignoring early rattling or tapping noises guarantees expensive internal damage.
• Rebuilt engines feature upgraded chains or valvetrain components to prevent recurrence.

The typical turnaround time for a Chrysler 300 / 300C engine replacement is 3 to 5 working days from the point of order confirmation. This includes sourcing the unit, palletised delivery, and professional garage installation.

• Sourcing and dispatching the rebuilt engine takes 1-2 working days.
• Professional supply and fit installation requires 1-2 days in the garage.
• Complex variants like the SRT8 may require slight additional sourcing time.
• We coordinate directly with the garage to minimise your vehicle's downtime.

Every reconditioned or rebuilt engine supplied through our network includes a minimum 12-month, unlimited mileage warranty as standard. This covers both parts and labour, providing complete peace of mind.

• The warranty is valid across the entire UK through our approved garage network.
• It specifically covers internal mechanical failures of the supplied unit.
• Regular servicing with the correct oil specifications must be maintained.
• Always confirm the specific warranty documentation with your chosen supplier before fitting.

While physically possible, swapping a V6 for a 5.7L HEMI in a Chrysler 300 / 300C is highly complex and rarely cost-effective due to extensive ECU, wiring harness, and mounting modifications required.

• The V6 and V8 use entirely different engine management systems.
• Custom wiring harnesses and ECU reprogramming are mandatory.
• Mounting points and transmission bell housings may differ significantly.
• We recommend replacing like-for-like to ensure reliability and legal compliance.

You can find your engine code in three places: on your V5C logbook (Section D.2), on the manufacturer's VIN plate under the bonnet, or stamped directly onto the engine block near the cylinder head.

• The V5C registration document is the fastest and most reliable method.
• Common codes are EXL (3.0 Diesel), EZB (5.7 Petrol), and ERB (3.6 Petrol).
• Providing the exact code guarantees 100% compatibility for your replacement.
• Our registration lookup tool can also identify this automatically for you.

Yes, replacing the engine is often significantly more cost-effective than purchasing a new vehicle, especially given the 300 / 300C's enduring comfort, road presence, and the high cost of modern depreciation.

• A rebuilt engine restores the car to better-than-used reliability.
• It costs a fraction of the monthly repayments on a new executive car.
• The vehicle retains its core value, interior luxury, and driving dynamics.
• Supply and fit options protect you from unexpected mechanic markups.

Yes, we offer a comprehensive, nationwide supply and fit service, connecting you with vetted, specialist garages across the UK who are experienced in handling heavy V6 and V8 engine installations.

• We handle the logistics, delivering the engine directly to your chosen garage.
• All partner garages are reviewed and rated by other Chrysler owners.
• You receive a single, unified warranty covering both the engine and the labour.
• No need to source a separate mechanic or arrange complex engine transportation.

While often used interchangeably, "reconditioned" typically implies a more thorough, ground-up restoration to OEM specifications, whereas "rebuilt" may focus on replacing only the specific failed components and associated wear items.

• Reconditioned engines are completely stripped, cleaned, and machined.
• Rebuilt engines address the root cause of the specific failure (e.g., lifters).
• Both options from our network undergo rigorous bench testing before dispatch.
• Both come with the same robust 12-month, unlimited mileage warranty.

No, replacement engines are supplied as long or short blocks and do not include the Engine Control Unit (ECU). Your vehicle's existing ECU is retained, reinstalled, and cleared of fault codes by the fitting garage.

• The ECU is coded to your vehicle's chassis and immobiliser system.
• Swapping the ECU would require complex, expensive dealer-level reprogramming.
• Specialist garages will perform an ECU reset to integrate the new engine seamlessly.
• Ensure your garage has the diagnostic tools required for the ECU adaptation.
