E. Limitation of duration:

Repairs or exchanges will not extend this limited warranty beyond the described term on this form (Item A).

F. Disclaimer 1:

This limited warranty is in lieu of any and all other expressed warranties of TOP TIER JAPAN. Any warranty implied is limited to the duration of this limited warranty. TOP TIER JAPAN does not assume or authorize any person to assume on its behalf any other obligation or liability. By making a purchase from TOP TIER JAPAN you agree with our warranty terms and conditions as listed in this section of the warranty.

G. Disclaimer 2:

TOP TIER JAPAN will not be responsible for incidental or consequential damages arising from loss of use, loss of time, inconvenience, or commercial loss, or any other consequential damage or loss. TOP TIER JAPAN does not provide install instructions or fitment guides for your purchase — be sure to know what you are buying before making your purchase.

H. Warranty claim procedure:

  1. To file a warranty claim, please contact TOP TIER JAPAN via email or phone and we will assist you in the procedure.
  2. The customer is responsible for all freight charges on the return of defective engines. No replacement engine will be sent until our staff have inspected and verified the returned defective engine in question. If the engine is defective, TOP TIER JAPAN will either send a replacement engine or issue a refund minus the shipping charges. This decision is based on TOP TIER JAPAN's discretion.
  3. The engine MUST be returned in the same condition it was sent in. If parts are missing or not in the same condition, it will be refused by the receiving team.

Engines complete with accessories may not comply with the emission control laws of the state in which they are being sold or used. State and/or federal authorities require that you change over the emission devices from your old engine to the engine you are installing to make it comply. Please note that TOP TIER JAPAN is not responsible for emissions or smog certification. The purchase price represents the cost of the long block only (i.e., cylinder head and short block only).

  2. Set ignition to specification as recommended by the manufacturer.
  3. Change oil after 200 initial miles post-install.
  4. Check cooling system and service if rusted or contaminated with oil, and replace coolant.
  5. Must replace the timing belt, water pump, tensioner, oil filter, and spark plugs.

Receiving & Inspection

Once you receive your item, please do not sign the release documents without fully inspecting the outer packaging for noticeable signs of damage. The freight companies will not let you open the packaging prior to signing the documents, therefore you must note any signs of damage based on the external packaging.

Shipping insurance is provided by the freight company, not by TOP TIER JAPAN LLC. If you sign the form and do not note any possible damages, the freight company will be relieved of all responsibilities and you will not be reimbursed for any damages done to your shipment caused during shipping.

You must notify TOP TIER JAPAN of any damages caused by mishandling during shipping.

PLEASE DO NOT SIGN THE RELEASE FORM OR LET THE DRIVER LEAVE WITHOUT FIRST INSPECTING THE PACKAGING FOR POSSIBLE DAMAGES.
