Detailed Description

Melling MPE-255R is intended for engine block service where expansion plugs and pipe plugs are needed to complete a rebuild. The kit is organized for common domestic and import engine applications, helping reduce time spent sourcing individual plugs during assembly. For Toyota 4Runner, Toyota Pickup, Toyota Camry, Toyota T100, Lexus ES300, and Lexus ES250 applications, this kit provides the plug coverage specified for the listed engine use.

The MPE-255R part number identifies a steel, press-fit, standard replacement solution from Melling's Stock line. This makes it a practical choice for engine builders who want a direct service part for cylinder block components. This part cross-references Monroe Shocks & Struts (e.g., 97-159, EPK-255R) for the same application.

What It Is Used For

• Replacing worn or corroded engine expansion plugs
• Completing cylinder block service during an engine rebuild
• Restoring sealing points in the engine water jacket

Installation Notes and Tips

Verify engine application before installation and compare the existing plug style, diameter, and block openings to the service requirements for the vehicle. Clean the block bores thoroughly before press-fitting the plugs, and inspect all sealing surfaces for corrosion or debris. Use the correct installation method for press-fit plugs to avoid distortion during assembly.
