2004 jeep grand cherokee expansive valve replacement procedures

Post by dieseldaisy »

Hi I am looking for help with learning how to properly and safely pull and replace and recharge my expansion valve in my 2004 jeep grand Cherokee 6 cyl 4.0 l
I am seeing the low side pressures holding steady at 5 psi and the high side holding at 225 psi?? expansion valve is the cheapest thing to start with right? I really could use step by step instructions on how to do this. do I need to evacuate? how does a diy do that all I see in the parts stores are vac systems but my understanding is that these are to only remove moisture after the repair and just before recharging?????????? Help!!!!!!

System will need to be pulled into a vacuum before charging.
