FAQ
Do I need a side plate on a stock truck?While many stock engines are fine with the factory core plug, a side plate is cheap insurance against aging seals, corrosion, and cooling system pressure spikes—especially on tuned or hard-worked trucks.
Will this fit both 12-valve and 24-valve 5.9L?Yes—this plate is designed for the 1989–2002 5.9L Cummins block’s side freeze plug location used across 12V and 24V engines.
Do I need sealant with the O-ring?Follow best practice for your machine finish: most installs use the supplied O-ring only. If the bore surface is imperfect, a thin film of coolant-safe sealant may be used sparingly.
Is any machining required?No machining is typically required. Ensure the bore is clean, round, and free of burrs or corrosion; light scotch-brite prep is common.
