Mazda CX-5 Service & Repair Manual: Hydraulic Variable Valve Timing Actuator Inspection
WARNING:
-
A hot engine can cause severe burns. Turn off the engine and wait until it is cool before servicing.
CAUTION:
-
Do not disassemble the hydraulic variable valve timing actuator because it is a precision unit.
1. Disconnect the negative battery cable..
2. Remove the plug hole plate..
3. Remove the ignition coil/ion sensors..
4. Remove the cylinder head cover..
5. Verify that the notch of the rotor and projection of the cover on the hydraulic variable valve timing actuator are aligned and fitted.
-
If the notch of the rotor and projection of the cover are not aligned, rotate the crankshaft in the direction the engine rotates two turns and verify that they are aligned.
-
If the notch of the rotor and projection of the cover are still not aligned, replace the hydraulic variable valve timing actuator..
-
If, when turning the crankshaft, there is a slapping noise from the hydraulic variable valve timing actuator each time before the cam reaches its maximum lift, it means that the actuator is not secured. Replace the hydraulic variable valve timing actuator..
6. Install in the reverse order of removal.
