Symptoms:

  • Delayed engagement
  • Push belt slippage

Cause:

A worn pump flow control valve and/or bore allow pump pressure to cross-leak into the low pressure side of the pump and reduce pressure available for the belt drive pulleys.

Correction:

Refurbish the pump flow control valve bore and install the Sonnax oversized pump flow control valve to restore adequate pressure for the pump drive pulleys.
