Installation & USDM Drop-In Notes

• Component Swapping (Crucial): While the structural engine block, pistons, oil pump, and cylinder head are identical, installers must transfer the original US-spec intake manifold, exhaust manifold, alternator, starter, wiring harness, and select electronic sensors from the old engine to ensure a direct plug-and-play match with the domestic vehicle's ECU.

• Oil System Prep: Due to known oiling sensitivities in the 2.4L Theta engine family, it is mandatory to prime the oil pump before the first startup, install a fresh OEM oil filter, and fill with premium high-grade full synthetic 5W-20 or 5W-30 motor oil.

• Preventative Maintenance: We highly advise replacing the rear main seal, front crankshaft seal, valve cover gasket, spark plugs, and thermostat while the engine is out of the vehicle to guarantee a completely leak-free, long-term repair.
