Engine warranty terms & conditions.

All goods and work carried out by Aircooled Hut UK Ltd are supplied subject to the warranty terms and conditions set out below. This warranty applies to failures resulting from defective materials or workmanship on road-use engines supplied by Aircooled Hut UK Ltd. Any engine classed as a Race Engine carries a limited warranty as detailed at the end of these terms.

• Reconditioned / Exchange Engines – 12 months, unlimited mileage, valid within the United Kingdom only.
• New Turnkey Engines – 12 months, unlimited mileage, valid within the United Kingdom only.

This warranty covers the engine long block and associated internal components, including the crankshaft, connecting rods, camshaft, bearings, pistons and cylinders, cylinder heads, rocker assemblies, pushrods and tubes, and flywheel.

Gearboxes supplied by Aircooled Hut UK Ltd are covered by the warranty provided by our chosen gearbox specialist.

Refurbished engines built into complete engines are video tested before dispatch. This video forms proof that the engine was running correctly prior to leaving our workshop. No warranty is provided on used parts fitted during refurbishment or on engine setup or tuning beyond this point.

The warranty covers defective workmanship and/or failure of components used during the engine rebuild. Aircooled Hut UK Ltd will, at its discretion, repair, replace or refund any defective component or engine found to be covered under this warranty, subject to the conditions below.

All engines must be tuned immediately on a rolling road to ensure correct fuelling. Failure to do so will invalidate this warranty.

Proof in the form of a VAT receipt and dyno graph printout must be provided in the event of a warranty claim.

Please instruct the rolling road operator not to carry out full power runs during the running-in period.

A running-in period of 500 miles is required following installation.

During this period:

• Do not exceed 3,000 RPM.
• Avoid prolonged constant engine speeds.
• Avoid full throttle acceleration.
• Vary engine speed whenever possible.

After the running-in period, remember this is a classic air-cooled engine and should be driven accordingly.

Engines must be operated using premium unleaded fuel (97 RON or higher) unless otherwise specified in writing by Aircooled Hut UK Ltd.

Damage caused by incorrect, contaminated or unsuitable fuel is not covered under this warranty.

The engine must be fitted and serviced by a reputable VAT-registered garage, with proof supplied to Aircooled Hut UK Ltd if requested.

The engine must be stopped immediately if any sign of mechanical failure or any significant oil leak develops.

Oil level must be checked regularly and all cooling tinware must remain fitted and in good condition.

Minor oil seepage is considered normal on classic air-cooled engines and is not covered under warranty.

Engine oil must be changed:

• After the first 20 minutes of running to bed in the camshaft (completed by Aircooled Hut UK Ltd on Turnkey Engines).
• At 100 miles.
• At 500 miles.

The 500-mile service must include:

• Valve/tappet clearance adjustment (excluding hydraulic lifter engines).
• Engine oil change.
• Ignition timing inspection and adjustment where necessary.

Ancillaries and consumable items are excluded from this warranty, including but not limited to:

• Distributors
• Coils
• Carburettors
• Alternators
• Clutch assemblies
• Filters
• Spark plugs
• Ignition leads
• Points
• Main oil seals

These items are covered only by their respective manufacturers' warranties where applicable.

At Aircooled Hut UK Ltd's discretion, replacement parts may be supplied as a goodwill gesture where a genuine manufacturing defect is identified within 28 days.

Engine tuning is not covered under warranty, including carburettor adjustment, EFI tuning, ignition timing, points adjustment or spark plugs.

Turnkey engines are started and initially tuned before dispatch to confirm correct operation. However, once installed in the vehicle, the engine must be professionally tuned on a rolling road immediately to account for the vehicle's weight, gearing, tyre size, drivetrain and other installation-specific factors that affect engine load and fuelling. Final tuning is the customer's responsibility. Failure to carry out immediate rolling road tuning may result in engine damage and will invalidate this warranty.

This warranty does not cover failures resulting from:

• Incorrect installation
• Poor maintenance
• Continued use after a minor fault develops
• Fair wear and tear
• Abuse or neglect
• Accident or impact damage
• Incorrect fuel or lubricants
• Racing, speed trials or competition use
• Unauthorised repairs or modifications
• Failure of customer-supplied or existing ancillary components
• External influences beyond our control

Cosmetic appearance is excluded from warranty, including paint finish, powder coating, corrosion, cosmetic wear and colour variation.

Photographs and/or video taken prior to dispatch shall be deemed acceptance of the cosmetic condition unless transport damage has occurred.

Unless otherwise agreed in writing at least one month before completion, all engine tinware will be finished in black.

Any engine or component requiring inspection under warranty must be returned to Aircooled Hut UK Ltd.

Removal, packaging, transportation and return carriage costs remain entirely the customer's responsibility, regardless of whether the warranty claim is accepted or rejected.

No warranty work will be authorised or reimbursed unless the engine or component has first been returned for inspection.

Aircooled Hut UK Ltd reserves the right to inspect all returned engines for evidence of overheating, misuse, incorrect installation or user error.

Where overheating, poor installation, negligence or deliberate damage is identified, all inspection, labour and replacement parts will be chargeable at current rates.

Aircooled Hut UK Ltd can arrange delivery on the customer's behalf; however, all transportation is undertaken by an independent third-party courier.

Once goods have left our workshop, the risk of loss or damage passes to the customer or their chosen carrier.

Customers are responsible for ensuring that the level of transit insurance is suitable for the value of the goods being transported.

Couriers used by Aircooled Hut UK Ltd generally provide only limited compensation based upon shipment weight. This may be substantially less than the value of an engine or gearbox.

Enhanced or full-value insurance is not available through our standard courier service.

Customers requiring full-value transit cover should arrange their own insured courier.

By choosing delivery arranged by Aircooled Hut UK Ltd, the customer accepts these insurance limitations.

Customers may arrange their own courier or collect goods in person.

Where a customer appoints their own carrier, responsibility for collection, transportation, insurance and delivery rests entirely with the customer and their chosen courier from the moment the goods leave our premises.

Aircooled Hut UK Ltd shall not be liable for any consequential or indirect losses arising from engine or gearbox failure, delayed delivery or transportation damage, including but not limited to:

• Towing charges
• Courier costs
• Vehicle recovery
• Storage charges
• Car hire
• Accommodation
• Loss of earnings
• Loss of business
• Any other incidental or consequential expenses

Any suspected warranty issue must be reported immediately in writing and supported with photographs where appropriate.

This warranty is not transferable.

If a reconditioned engine is replaced under warranty, the replacement engine will carry only the remaining balance of the original warranty period.

This warranty applies only within Mainland United Kingdom and Northern Ireland.

The warranty terms applicable shall be those in force on the original invoice date. Aircooled Hut UK Ltd reserves the right to amend these terms for future sales.

Engines fitted with camshafts exceeding 0.350" lift, crankshafts larger than 69 mm, producing over 100 BHP, or using EFI, turbocharging or nitrous oxide systems are classed as Race Engines and are not intended for normal road use.

Any road-based engine used in racing or motorsport is also classed as a Race Engine.

Race Engines carry a 30-day limited warranty covering the long block only and excluding tuning, cosmetics and cooling systems.

All parts, engines and gearboxes must be inspected immediately upon delivery.

Any visible transit damage must be reported within 24 hours of delivery.

Any shortages, defects or discrepancies must be reported within 7 days of delivery.

Failure to notify Aircooled Hut UK Ltd within these timescales may invalidate any related claim.

Nothing in these warranty terms affects the customer's statutory rights.

Trade customers are responsible for ensuring these warranty terms are passed to their own customers.
