1 Year Rebuilt Engine Limited Warranty

What is warranted under this Rebuilt Engine Limited Warranty (“contract”)

  • Timbukthree 4WD provides a limited warranty for its rebuilt engines (referred to simply as “engine” below) against knock, cracked block, cracked cylinder head, and excessive smoking for 1 year starting from the date of the Warranty Effective Date. This is a 1 Year Parts Warranty.
  • If (and only if) Timbukthree 4WD sells the engine and installs it, it provides the 1 Year Parts Warranty and a limited warranty for the installation of the engine. This is a 1 Year Parts & Labor Warranty.
  • You have either a 1 Year Parts Warranty or a 1 Year Parts & Labor Warranty depending on whether Timbukthree 4WD installs the engine.
  • If Timbukthree installs the engine, Timbukthree 4WD replaces the thermostat and water pump and these items are included in the 1 Year Parts & Labor Warranty. Seals and gaskets are all new and are warranted under the 1 Year Parts & Labor Warranty if Timbukthree 4WD performs the installation.
  • Although the seals and gaskets for the engine are all new, Timbukthree 4WD does not warrant themif Timbukthree 4WD does not perform the installation.
  • This limited warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

This is a one year limited warranty

  • The limited warranties described above are both for 1 year.
  • Timbukthree 4WD rebuilt engines consist of the following: Engine block, crankshaft, connecting rods, pistons, piston rings, bearings, cylinder head with valves & springs, oil pump, oil pickup, oil filter adapter (if applicable), camshaft, timing set, timing cover, harmonic balancer/damper, valve cover, oil pan, oil dipstick, freeze plugs; and the following gaskets: Valve cover, cylinder head, thermostat, water pump, intake/exhaust, distributor, timing cover, oil pan, front crank seal, and rear main seal.
  • Any and all necessary warranty repairs to the engine under the 1 Year Parts & Labor Warranty must be made by Timbukthree 4WD and will be made free of charge. If the repairs are performed by any other person or shop, you will not be reimbursed for the cost of those repairs.

There is a one year limit on implied warranties

  • All implied warranties (including merchantability and fitness for a particular purpose) expire on the Warranty Expiration Date that is set forth on the signature page of this contract. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.

Deadline to make a limited warranty claim

  • Any warranty claim must be presented to Timbukthree 4WD before the Warranty Expiration Date set forth on the signature page of this document. If you attempt to make a warranty claim after the warranty period has expired – even if you believe you were experiencing issues before to the end of the warranty period – the warranty is still expired and void.

What is not covered by the limited warranty

  • This limited warranty does not include Timbukthree 4WD paying for any incidental or consequential damages that are incurred as a result of any warranty issue (including, but not limited to, lost income, towing charges, childcare expenses, public transportation/taxi/ride-share expenses, costs of a rental car, costs of replacing any property that is damaged if the rebuilt engine fails), or any issue that is determined not to be a warranty issue. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

What to do if a warranty issue is suspected

If you experience an issue you believe may be related to the engine, you must take the following steps:

  • Call Timbukthree 4WD and describe the issue. If the issue sounds like it is related to the engine, we will schedule a warranty claim inspection.
  • If the issue does not sound like it is related to the engine, Timbukthree 4WD will instruct you to take the vehicle to a licensed repair shop (not Timbukthree 4WD) for an initial, professional diagnosis on root cause of the issue. If the repair shop determines the cause of the issue is related to the engine itself or any new components related to the engine that Timbukthree 4WD installed as part of the engine installation, provide Timbukthree 4WD with the written diagnosis. Timbukthree 4WD will then schedule a warranty claim inspection.
  • If you have the 1 Year Parts & Labor Warranty, and pay a diagnostic fee to another shop to determine the root cause of an issue and Timbukthree 4WD verifies the issue is covered under this limited warranty, Timbukthree 4WD will pay the reasonable cost of the diagnosis as long as there is proper documentation of the diagnostic work and the amount of the fee.
  • If you have the 1 Year Parts Warranty only, Timbukthree 4WD does not at any time provide technical or troubleshooting support. Any direct or incidental costs incurred by the customer to install the engine and/or diagnose a suspected issue will not be covered or reimbursed by Timbukthree 4WD.

 What to do if a warranty issue is diagnosed

  • If the engine or engine components installed by Timbukthree 4WD are verified by Timbukthree 4WD to be the source of the problem, Timbukthree 4WD will schedule an appointment to perform the warranty work within a reasonable time after verifying the diagnosis. Replacement parts will be provided under the 1 Year Parts Warranty free of charge, or if there is a 1 Year Parts & Labor Warranty for the engine, Timbukthree 4WD will provide the replacement parts and perform any necessary repairs to the engine free of charge.
  • Under the 1 Year Parts Warranty, labor costs (or monetary compensation for time spent) for anyone other than Timbukthree 4WD to install the engine are not covered by this warranty and will not be reimbursed.
  • If a warranty claim is made under the 1 Year Parts Warranty and verified by Timbukthree 4WD, replacement parts will be provided to you, but labor costs, any incidental or consequential damages (including, but not limited to, lost income, towing charges, childcare expenses, public transportation/ taxi/ride-share expenses), and any other direct or incidental expenses or damages incurred to install the replacement parts provided by Timbukthree 4WD are not covered by this warranty and you will not be reimbursed under the 1 Year Parts Warranty.
  • If a warranty claim is made under the 1 Year Parts & Labor Warranty, and verified by Timbukthree 4WD, towing charges (if necessary), replacement parts and all labor charges will be provided free of charge. However, other incidental or consequential damages such as lost income, childcare expenses, public transportation/taxi/ride-share expenses, and any other direct or incidental expenses you incur are not covered by this warranty and will not be reimbursed under the 1 Year Parts & Labor Warranty.

What to do if the warranty issue is not resolved after a reasonable number of efforts

  • If Timbukthree 4WD provides warranty work under this contract but is not able to resolve the issue after a reasonable number of efforts, you will have the option of choosing a replacement part or a refund.
  • The limited warranty is void under certain circumstances
    • All warranties are void under the following circumstances: if the engine has been disassembled before our inspection, if the center of installed heat tab has been melted (overheated) or removed, unreasonable use or abuse of the engine, act of God (such as a flood), or if you have not performed reasonable and necessary maintenance.
    • Reasonable and necessary maintenance means:
      • Perform regular 3,000 mile/3 month oil changes, whichever comes first. The preferred oil for this engine is Shell Rotella – T 15W40, or an equivalent. Diesel truck motor oil is preferred because of the ZDDP (Zinc) content in the oil, which will protect the flat tappet camshaft throughout its life.
      • Flush the cooling system if any sort of stop-leak has been used.
      • Do not allow the engine to overheat. Overheating can be caused by many things such as a bad radiator, bad water pump, bad thermostat, any kind of clog or leak in the cooling system, cracked cylinder head, or an inoperable cooling fan. If your temperature gauge ever starts to rise past its normal temperature, pull over and turn the vehicle off immediately to prevent overheating.
      • Take other actions reasonable under the circumstances.

 The limited warranty cannot be transferred to anyone else

  • You cannot transfer this limited warranty to anyone else. All engines are marked with Timbukthree 4WD’s markings and a serial number. The 1 Year Parts Warranty applies to a specific engine sold to a specific customer, and the 1 Year Parts & Labor Warranty applies to a specific engine installed in a specific vehicle. Warranties are void in the following circumstances:
    • If the serial number has been defaced,
    • If the engine is removed and installed in another vehicle and/or
    • If there is a change in ownership of a vehicle in which a Timbukthree 4WD engine has been installed (whether installed by Timbukthree 4WD or another person or shop).
  • If you purchase an engine from Timbukthree 4WD and have it perform the installation with the intent of then selling the vehicle, you (not the buyer) may request to have the remaining warranty transferred to the vehicle buyer. The decision to permit the transfer is at the sole discretion of Timbukthree 4WD, and must be documented and agreed to in writing. No warranty with 6 or fewer months remaining in the warranty period is eligible to be transferred.

General Provisions

  • Any notes on an invoice for parts or service will control over a conflicting provision in this contract.
  • Cores (your old engine) become the property of Timbukthree 4WD if it installs the engine unless you and Timbukthree 4WD agree otherwise before the installation of the engine.
  • This contract is governed by Colorado law. Any action or proceeding to resolve any dispute regarding this contract must be brought only in the courts located in Colorado.
  • This contract contains all of the terms and conditions of the limited warranty, and cannot be changed unless Timbukthree 4WD has agreed to the changes in writing.
