The flow rate through the oil cooler is half of the designed flow rate; does this affect the flow of oil within the cooler?

The lubricating oil cooler of the compressor unit is designed with a flow rate corresponding to the outlet flow rate of the lubricating oil pump, which is 13 cubic meters per hour. However, the flow rate through the oil cooler, as measured using a portable ultrasonic flow meter, was only 6 m3/h – half of the designed flow rate. The remaining half of the flow returned to the oil tank via a pressure control valve. If only half of the designed flow rate passes through the oil cooler, could this result in no flow of oil? On-site measurements confirmed that indeed no oil was flowing inside it. How can this situation be resolved?
