Please follow these steps carefully. Failure to do so can void your warranty.
🔧 1. Replace Timing Components & Seals

- Replace all external seals, including:
- Crankshaft seals (front and rear)
- Camshaft seals
- Oil pan gasket
- Valve cover gasket
- Intake manifold gasket
🔄 2. Transfer Accessories
Move over all accessories from your old engine to the replacement. This includes:
- Sensors
- Brackets

The recycled engine comes with accessories for convenience only. These are not covered under warranty and should not be relied on.
💧 3. Install New Water Pump & Thermostat
- Install a new water pump.
- Replace the thermostat with a new one.
- Use a 50/50 mix of antifreeze and water.

🧼 4. Clean the Intake & Ports
- Clean out the intake manifold thoroughly.
- Check the intake and exhaust ports for any loose bolts, nuts, or debris.
⚠️ Important: Debris from a failed engine can get stuck inside the intake and cause serious damage to the new engine. This is the installer’s responsibility.
🛢️ 5. Change Oil & Filter
Install a new oil filter.
Add fresh oil before the first startup.
Change oil and filter every:
3,000 miles, or
As recommended by your vehicle's manufacturer
(Never go over 5,000 miles between oil changes.)
Keep receipts for oil changes as proof of maintenance.
🔍 6. Final Inspection
- Double check all sensors and connectors.
- Make sure everything is tightened to spec.
- Prime the engine with oil if needed (especially for long-stored units).
- Crank the engine a few times without starting to build oil pressure.
