Good To Know

Q: Why do these solenoids fail over time? A: Over time, dirty engine oil can clog the fine mesh screens of the solenoid, restricting oil flow and causing timing errors.

Q: Should all solenoids be replaced simultaneously? A: Yes, replacing all four solenoids simultaneously ensures balanced performance across both intake and exhaust camshafts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
