FAQ

Q: Is this piston a direct fit for my Mitsubishi S12R-PTA2 engine?
A: Yes, part number 37517-30101 is designed for Mitsubishi S12R-PTA and S12R-PTA2 engines. However, we recommend verifying your engine serial number and comparing with your existing piston to ensure a perfect match, as there may be variations in different production batches.

Q: What installation precautions should I take?
A: Ensure the cylinder bore is clean and within specifications before installation. Use new piston rings and wrist pins as recommended. Lubricate the piston skirt and rings during assembly. Always follow the engine manufacturer’s torque specifications and procedures for connecting rod bolts.

Q: How do I maintain optimal piston life?
A: Regular oil changes with the correct viscosity grade, maintaining proper coolant temperature, and avoiding prolonged overloading will extend piston life. Monitor for abnormal exhaust smoke or compression loss, which may indicate piston or ring wear. Inspect during scheduled engine overhauls.
