APS Preinstallation guide for used engines

✅ Step-by-Step Installation Guide

For Used Engines
Please follow these steps carefully. Failure to do so can void your warranty.

🔧 1. Replace Timing Components & Seals

• Install a new timing belt (If suggested by your installer)
• 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
• Pulleys
• Belts
• Mounts

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.
• Check the cooling system for leaks before startup.

🧼 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.
