Warranty
All of our engines and transmissions come with a six-month unlimited mileage warranty. You can drive as much as you like during this period. Please note that this warranty covers only the engine or transmission itself and does not include labor costs.
The warranty begins on the date of purchase and will expire six months later. All claims must be submitted within this timeframe.
This warranty covers the engine long block (including the block and heads) and internal components, but it does not extend to external accessories. While most of our engines arrive complete, some parts may differ from your original components. During shipping from Japan, it’s not uncommon for parts to sustain minor damage or scratches. If this occurs, simply replace these parts with your original ones. We recommend using your original accessories during installation. For more details, please refer to item #2 of our six-month limited engine and transmission warranty.
If you encounter any issues with your engine or transmission, please reach out to us as soon as possible. We will collaborate with you and your mechanic to identify the problem, attempting to resolve it while the engine or transmission is still installed. If we cannot resolve the issue in situ, we will authorize a warranty replacement. Please ensure that your original parts are removed from the product before returning it for warranty, as we will need to arrange for the warranty item to be picked up and shipped back before we can send out a replacement.
Purchaser Agreement and Warranty Terms
The purchaser acknowledges that Engine Tech Hub is not liable for any costs associated with labor, parts, towing, installation, dismantling, reinstallation, transportation, freight claims, car rental, loss of wages, or any other related expenses.
This warranty is limited to the engine cylinder head and block assembly or transmission, specifically excluding coverage for the following components: fuel injection parts, carburetor, intake and exhaust manifolds, distributor, alternator, emission control devices, smog pump and components, seals, timing belt (and related tensioners and idler bearings), timing cover, thermostat, water pump, flywheel or flex plate, pulleys, valve cover, sensors, switches, oil pan, oil pickup tube, turbocharger, and intercooler (if applicable). These components must be transferred from the original engine and must be in good working condition.
The purchaser is responsible for all freight charges, including those related to the return of the core. The warranty becomes void if the head or any internal parts of the engine or transmission are removed or disassembled.
Any warranted item will be replaced with an identical item and will remain covered under the original warranty terms. If issues arise with the engine or transmission, the purchaser must notify Engine Tech Hub for inspection before removal from the vehicle; the unit must remain intact as originally installed.
To ensure proper function, the purchaser must replace the thermostat, radiator cap, water pump, belts, hoses, and sensors. Additionally, a new radiator must be installed, or the existing radiator should be tested, flushed, or rodded by a qualified service facility.
The purchaser must also install new gaskets for the oil pan, front and rear crankshaft seals, camshaft seals, and valve cover gaskets; these are not covered under the warranty. It is the purchaser’s responsibility to have the engine tuned, timed, and valves adjusted, if applicable.
All engines sold include heat tabs, which the purchaser acknowledges receiving. The warranty will be void if any heat tabs are missing or melted, as melting occurs at 255 degrees due to overheating.
For all belt-driven engines, the purchaser must replace the timing belt and set the timing. Engine Tech Hub is not liable for damage resulting from a broken or stripped timing belt.
The warranty on transmissions applies solely to the transmission itself and excludes switches, sensors, passing gear cables, speedometer gears and cables, linkage, torque converters, and shift handles. The warranty will be void if improper lubricant is used in the transmission or differential.
Purchasers must flush all cooling lines and replace any inline transmission filters. Additionally, a new oil pan gasket, front, rear, and/or axle seals, torque converter/front pump seal, and transmission oil filter must be installed. Engine Tech Hub is not responsible for these seals, gaskets, or filters.
Refunds will not be issued for any items after 10 days from the purchase date. All exchanged or returned items must be in their original condition and accompanied by the original sales receipt. A 20% restocking fee will apply to all returned items.
Engine Tech hub is not responsible for any damage or defects resulting from improper installation. Failure to adhere to any of the stated warranty conditions will void the warranty.
No agent or employee is authorized to modify this warranty in any manner, verbally or in writing. The purchaser is responsible for any legal fees related to non-payment of any purchase.
Position both transmissions side by side and verify they are an exact match before installation. Ensure the bell housing bolt pattern, sensor locations, harness connectors, cooling lines, and axle fitment align properly.
Flush or replace the transmission cooler and lines prior to installing the new transmission. Old fluid can get trapped in the cooler and potentially contaminate the new unit if not properly cleaned.
Install a new fluid filter and pan gasket before refilling with fresh transmission fluid.
Replace the input and output shaft seals where applicable.
Replace the axle seals as needed.
Transfer all necessary components such as the 4×4 transfer case, sensors, switches, solenoids, and cooling lines from the original transmission to ensure proper functionality.
Note: Sensors and solenoids included with our transmission have not been tested.
Inspect all electrical connectors for signs of corrosion or debris, and check for any damaged or missing pins.
Consult the full fluid refill specifications for your transmission model. Always use the OEM-approved fluids. Since our transmissions are shipped dry, they require the full refill amount, which will typically exceed the standard drain-and-refill quantity by a few quarts.
Pre-fill the torque converter and install it onto the input shaft, ensuring it is fully seated through all three engagement steps before mounting the transmission.
Monitor fluid levels as the vehicle heats up and reaches operating temperature. You may need to top off the fluid several times to achieve the correct level.
Clear all diagnostic trouble codes before installing the new transmission.
Check for any leaks prior to a test drive. We recommend driving the vehicle for 15-25 miles to ensure everything functions correctly before completing the job.
- Position both engines side by side and confirm that the cylinder head(s) and engine block are an exact match before disassembling any components.
- Carefully compare the accessories on both engines and transfer any necessary parts. Components such as the intake, exhaust, valve cover, engine mounts, brackets, oil pan, and various accessories may need to be moved from the original engine.
- Transferring these parts is essential for ensuring compatibility with your vehicle and adherence to state emissions regulations.
- Swap the oil pan and pick-up tube, as they are a matched pair.
- Install new front and rear main crankshaft seals.
- Replace the timing belt, if applicable.
- Install a new water pump and thermostat.
- Replace all hoses and clamps related to the cooling system.
- Install a new radiator and fill both the engine block and radiator with coolant.
- (This step ensures coolant is present behind the thermostat, allowing it to open properly.)
- Replace the spark plugs and wires.
- Clear all diagnostic trouble codes from the vehicle’s computer system before starting the engine.
- Bleed and purge the cooling system to remove any trapped air, ensuring that the thermostat is functioning correctly. You may need to top off the coolant several times before reaching the proper level. Verify proper coolant flow before running the engine for extended periods or driving.
- Manually rotate the crankshaft before installation and startup to ensure no internal obstructions.
- After starting the engine, allow it to warm up fully. Monitor the temperature gauge, and ensure that the cooling fans engage when the engine reaches its operating temperature.
- Inspect for any leaks before taking the vehicle for a test drive. We recommend driving 15-25 miles to confirm everything is functioning correctly before considering the job complete.
