[QUOTE="dontaskme, post: 131903, member: 24334"] The engine cooling fan is the fan situated underneath the cooling pack, it is a hydraulic flow through fan that is ALWAYS on whenever the pumps are rotating, if it wasn’t then the pump coupling has failed & your machine would never move until it’s repaired. If you mean you have an ac system with the condenser & electrical fan motors on the back door, that fan really should only get power (electrical) when the ac switch is engaged. As for your ac system, if you suspect a leak check the hoses going to the condenser from the engine compartment they tend to blow due to them being crushed when the door is closed. [/QUOTE]
