If your 2V-700 experiences a slowdown of coolant transfer (2.5 gallons per minute normal flow rate), the probable cause is a defective quick disconnect fitting. This is especially true with the Rectus-TEMA fitting used as the Volvo /Mack style QD fitting. Mineral deposits and other contaminates can lodge in the QD fitting causing it to be restricted. To test your 2V-700 just draw some coolant or water into the tool then attached the hand valve assembly and pressurize the tool to 25 PSI. Squeeze the hand valve handle and monitor the flow rate.

Another cause could be a leak in the 2V-700 system. To test that, pressurize the tank and see if it will hold the pressure for 5 minutes or so. If it won’t, use soapy water to spray on the connections that could be leaking and look for bubbles. If bubbles are found, tighten fittings or parts as needed.

After these tests you should have confirmed the cause for the slow operation. If a replacement QD fitting is needed, we stock them.
