Vent temp can get down in the 40's. If you don't have gauges, pay someone who does. Don't want to overfill. Most DIY don't have recovery equipment, shops do. So they can take out the refrigerant you have, vac system down, leak test, etc., and put back your refrigerant plus a little more if needed.

 

Well just to clear some confusion some might have... The size of bolt for the hub pulley on these compresors uses a 10mm socket but the actual size is M6x20mm. That is a 6mm x 20mm ... My issue is how the heck does one lock it up? Im assuming direct battery lockup? i sure cant hold it still by hand! Lol

 

there is usually a spanner wrench that fits in the holes on the face of the clutch.
some choices are:
hit it with am impact gun,
make a tool the will fit into the holes in the face of the clutch.
most rental or auto parts store will rent you the tool.

Sending 12vt to the clutch to lock it will not work, as once the clutch locks you will spin the compressor.

 

Yeah i just thout of that however it is on the belt... Ill hit it with impact... I usually stay away from impact but inthis case... Its not a "LM part"

 

You can get this part from Autozone.
Santech A/C Comp Clutch Installation Kit

Part Number: MT0985

I just recently had the pulley clutch cover come off. Good thing it did not went into the fan. I just changed my water pump and radiator so was very fortunate that I got no damage. The cost of this clutch install kit is $9.99 right now. However I don't know if the price went up.
