Once you have your new unit installed just give us a call and our core team will get you what is called a bill of lading. You can also fill out our online core return form. Once the Bill of lading is sent to you, please print off two copies and hand both of them to the carrier when they arrive, and your core will be sent back to be remanufactured for a new customer to enjoy.
Notes: *If a customer returns the item themselves, without contacting Go Powertrain, they will be responsible for paying all of the freight. The customer will not be reimbursed for the cost of the freight if they do not contact Go Powertrain to return the unit.
RETURN GUIDELINES: For core credit, the core must be...Returned in original packagingFully assembled and to the same build level as the replacement part provided by Go PowertrainVisually remanufacturable
IMPORTANT:Unit price does not include core charge. Core must be returned within thirty (30) days or you will be charged the value of the unreturned core. Please contact Go Powertrain to schedule your core return when it is ready for pickup. This applies to most U.S. customers. Outside of the U.S. a core charge will be evaluated as the core may not be cost effective to return back.
Remanufactured
A remanufactured product is restored to a condition as close to new as possible. This means the part has been rebuilt to meet the same standards as a brand-new part. Key components, such as the block casting, crankshaft, and camshafts, are thoroughly inspected to ensure they are free of defects. These components are then remachined to meet OEM tolerances. If a component cannot be restored to these specifications, it is discarded and replaced with either a remanufacturable component or a brand-new one. All internal wear-prone parts are replaced with brand-new components.
For remanufactured engines, every unit includes a new oil pump, with some applications featuring a high-flow oil pump when necessary. Additionally, remanufactured engines come with a complimentary gasket set to facilitate installation.
Rebuilt
Rebuilt parts are disassembled and repaired only at the points of failure. While this process addresses the specific issues, many wear-prone components are reused, and little to no comprehensive testing is conducted to ensure the overall reliability of the product.
Used
Used parts are salvaged directly from donor vehicles, often sourced from salvage yards. These parts are typically left in their original condition, though they may be cleaned and minimally tested, depending on the capabilities of the salvage yard and the condition of the donor vehicle.

A Certified Pre-owned engine is not unlike a Certified Pre-owned car. There are a base set of standards and criteria the engine must meet to pass a Certified Pre-owned inspection. The engines are tested on a SIM test stand (simulates running) meaning the engines are rotated at normal operating RPM so the following can be checked:
- Compression- Compression testing indicates if the cylinder bore area seals up which is very important for the performance of the engine. Too low compression or uneven compression between cylinders would indicate there is excessive wear on the rings or valves and these could cause high oil usage, check engine light to illuminate or even early engine failure.
- Oil pressure and oil flow- Oil pressure is key to proper engine lubrication. High oil flow will give you low oil pressure which may be an indication of severe wear on the bearings. Also, t he incorrect oil pressure may set a code and illuminate a check engine light if it isn’t correct.
- Torque to Turn- Torque to Turn measures the amount of resistance for the engine to operate. If the engine is too tight and hard to turn, this may indicate the engine had been improperly maintained.
- VVT/VCT-Variable Valve Timing and Variable Cam Timing are common on today’s engines and are critical for the engine components to work on-time to optimize performance. When operating properly, these units help control fuel mileage as they reduce compression on the cylinders as the engine gets up to operating capacity.
The engines being produced today by vehicle manufacturers are very sophisticated. They are lower cubic inch engines that run at higher RPM’s to create better performance and improved fuel economy. GPT’s engines are 3-7 years old with varying mileages. Mileage is not the best factor to determine the engine’s quality or longevity. Other factors, such as how the engine was maintained by the previous owner are far more significant. The process GPT uses will tell us everything you need to know about the quality of the engine.
Your expectations of a GPT engine should be no less than the day it was built.
We believe a Certified Pre-owned engine from GPT will provide you a high-quality, high-value replacement engine without being modified or re-machined as remanufactured engines are.

When you purchase a new or remanufactured product, you are required to return your old, defective product—this process is known as a core return. Core returns are essential for two key reasons: they ensure proper disposal of used products and provide the materials needed to create new remanufactured products. Components such as castings, casings, and certain internal parts are carefully inspected, remachined, and reused whenever possible, contributing to sustainable manufacturing practices.
If you are not returning your core or if your core is damaged or if you do not return you core within the allotted time, you will be assessed the core charge. A core charge is a fee that is assessed based upon the core value of the item you are purchasing. There is no standard rate for a core charge as it depends on the item. Core charges are refundable once the item has been returned. There are instances where you can return an item and the core charge will still be assessed if the item was deemed unvaluable.
A valuable core is a core that is free of any physical damage such as cracks or holes. Any crack or hole in any will deem it to be an unvaluable core. If a core is deemed unvaluable you will be assessed either the entire core charge or a partial core charge. If you are in question about the status of your core it is always best to get with your sales representative and send pictures of the core in question that way you will know what to expect up front.
No every core will be assessed a full core charge. Since many of the components inside powertrain products can still be useful regardless of the appearance of the casing or block. Often times a customer will just have to pay a portion of the core fee. The partial core is determined by a percentage of the complete core value of a product based upon may factors such as the location of the damage and how severe it is.
