Help please 01 ls v8 hydraulic pump

[Rsully701]

I just bought a new actuator for the pump the fan does turn slow still I'm curious if the pump is bad if the pump is bad will the fan still spin I don't have any freon in cuz I just put in a new engine so when I turn the AC on the fan does not kick on her should I go buy freon and put it in and turn on the AC to make sure that the actuator works if not I should send back the actuator correct thank you very much for your time

I just bought a new actuator for the pump, the fan does turn slow. Still, I'm curious if the pump is bad... IF the pump is bad, will the fan still spin?

I don't have freon in because I just put in a new engine. When I turn the AC on, the fan does not kick on her. Should I go buy freon and put it in, then turn on the AC to make sure that the actuator works? If not, should I send back the actuator? Thank you very much for your time.

When you turn the AC on, the fan speeds up in proportion to the high-side pressure of the AC system. If there is no refrigerant, then there is no pressure, so the fan does not speed up.
The LS uses R-134a (Suva) refrigerant, not R-12 (Freon) refrigerant.
You can't just put refrigerant into a previously opened system. You must pull a full vacuum for at least thirty minutes to boil all the moisture out. You also need to make sure that the correct amount of the correct compressor oil is in the system. Also, the receiver/dryer must be replaced as it is saturated with water by now.

You can test the fan with a good OBDII scan tool that allows you to set the fan speed during test. You could also test by idling with something blocking airflow to the radiator.
Or, you could, you know, just drive it and see if your overheating problems are gone...

Well you can, I used to do it on my junkers all the time when a $5 can would get me A/C for 6 months, wasn't worth it to fix it. Just means the A/C system's operating life is diminished and it's not as efficient.

The moisture will freeze in the evaporator, greatly cutting the cooling capacity right away. Might not have been as much of a problem before the switch over to micro-channel evaporators.
