Tool Required VB-FIX Required
- Chatter on acceleration
- Push belt slippage & pulley fracture
- RPM surge on acceleration
Loss of pressure control to the secondary pulley. Low pressure to the pulley causes chatter, push belt slip, surface fretting and metal contamination. With low pressure, pully diameter will not change and ratio remains the same.
Refurbish the bore using the Sonnax tool kit and install the Sonnax control valve and end plug.
Oversized Secondary Pulley Control Valve Kit
- End Plug
- Sonnax valve is hard-coat anodized aluminum to increase wear resistance.
- Reuses the OE spring.
