[QUOTE="Texasmark, post: 1515623, member: 27848"] If you don't have a cooler it will get hotter than with a cooler. If you have any cavitating valves in the circuit you will increase the fluid temp by the introduction of turbulent flow vs laminar......squealing hydraulics is cavitation. Every time you go thru a QD coupling (especially) or through any fitting/transition mechanism from the smooth pipe/hose used in the majority of the system you are setting yourself up for cavitation. There was a hydraulics guy on another forum said that sometimes it helps to put ¾" couplers on ½" hoses (adapters obviously required) to keep the flow through the valve laminar. Makes sense. [/QUOTE]
