Remanufactured engines consist of the re-machined long block, and they include block casting. With any purchase, you can expect the following to come with the remanufactured engine:
- Connecting rods
- New rod bearings
- Camshaft and timing chain
- Cylinder heads (including head castings and all required machining)
- New valves
- New rocker arms, pushrods, and lifters
- Full gasket set
- New oil pump
Our remanufacturing process entails that every part has been re-machined or replaced to meet or exceed OEM standards. Our remanufactured engines are among the highest quality in the industry today.
Our core return policy helps us manage the cost and supply to continue our remanufacturing process. The core is your old engine that is being replaced which needs to be sent to us. For core returns, we cover all shipping costs.
Please keep in mind that our FREE core return shipping is ultimately the customer’s responsibility. While we handle the cost, it is up to you to initiate the process and arrange for the core pickup. When your new part installation is finished, you can reach us by phone at(877) 343-7352. You can also visit our core return page to arrange the core return.
Schedule your core pickup within 30 days of delivery, and there will be no upfront core charge (there are exceptions when our Waive Core Now option is unavailable).
With our Waive Core Charge service, core returns are simplified. Your core charge is waived for 30 days, so your new engine can be installed prior to returning your core. When you select this option, you give Reman Engine the right to bill your credit card if the core return is not returned within 30 days of part delivery (some exceptions do exist and will be noted in the purchase agreement).
In the case that the core is not returned or not paid for, the warranty for the remanufactured engine is void. If the core charge is billed prior to the core return, there will be a $50 processing fee that will be deducted from the core return refund.
Reman Engine offers free shipping to commercial locations. Home businesses and businesses that are not commercially zoned are not considered commercial addresses.
The commercial location must be able to receive freight shipping with no need for prior notification. Forklift unloading from the truck is necessary. We ask that commercial businesses enable us to ship directly to the repair shop or dealership doing the work.
Some locations (typically remote areas) may require an additional delivery fee. These locations include but are not limited to select locations in CO, UT, NY, OR, and CA.
High order volumes, inclement weather, or other circumstances outside of our control can impact shipping and delivery times. We always try to ship your order as soon as we possibly can. It should be noted that shipping times are our best estimate and not a guarantee. We also do not assume responsibility for additional fees charged by the carrier related to storage or re-delivery issues.
All of our parts are inspected and tested before shipping. Sometimes, damage does occur during shipping. It is very important that you inspect all parts for damage when they are delivered. Please report any damaged, missing parts, or wrong orders. A failure to report any problems inhibits our ability to correct them and puts all responsibility on the receiver.
At Reman Engine, we warranty all engine parts. We guarantee that they will ship with no defects in materials or workmanship. All warranty periods begin from the date of installation, contingent on the installation being managed by a Licensed Automotive Repair Facility.
