***Warranty information:***
Borg-Warner warranties any failure due to manufacturer defects for 12 months. In the event that a turbo purchased direct from JHM is not performing to manufacturer specifications, the customer will be responsible for purchasing a replacement until the warranty review process is complete if they are not willing to wait until the review is complete. The malfunctioning part will then be sent out for warranty inspection immediately after it is received by JHM, at which time we will wait to hear from Borg-Warner as to whether the item failed due to manufacturer defects or for other reasons. The most common reasons of a rejected warranty for any turbo but not limited to are: oil pressure and/or feed lines that have excess sludge or deposits in them thus releasing deposits into the turbo and causing failure - oil pressure and/or feed lines that are plugged or partially plugged thus restricting oil to or from the turbo causing failure - damage caused due to improper installation - poorly maintained engines that have oil sludge and deposits that get released into the new turbo. After inspection if the suspected defective turbo is determined to be truly defective by the manufacturer you will be sent back a replacement or refunded for the amount of the replacement you purchased if you bought one in advance as previously stated. (excluding shipping). JHM and Borg-Warner are NOT responsible for the labor costs associated with the install of these items nor the labor costs associated with replacement of warrantable parts. For further information please contact JHM.
