oh alright
once these parts come in the mail i can see what im exactly dealing with, but your saying the high and low side is totally different, or is the fitting just different on the inside?

 

Ok both are considered Schrader valves but have very different looks.

Low side looks like this



The high side looks like this



They come in many sizes and shapes just make sure the ones you get are for your Dakota http://www.acschradervalves.com/

 

I guess one way to describe the differences is the low side ones you are just replacing the inside of the port but the high side is an all in one part it’s the port the housing and the valve all in one bigger part.

Seems weird dont ask me why they did it that way they just did?

 

there's all my parts stacked together. got everything replaced that i thought needed to be and gave up on trying to do every o ring, since the quick release tool i got wasn't so quick. got a -30 vac, got gages reading low at 35 and high at 145 and called it a night. was working on this from 5 to 10, since i hit some bumps here and there. might put some more freon in later this week.

 

First time is always the hardest.

These can be a bitch to get apart but I didn’t have any problems.

Why you got the complete orifice tube and line is a strange one $30 compared to $5 those lines don’t need replacing just the orifice tube the little plastic thing.

I never looked at it like a one day job first day is getting things apart and a few things together second day finish up.

You need patience that’s all.

Did you get a look at the old orifice tub to see if it was dirty at all?

 

ill take a look later on its in the back of the truck on my way to school this morning my compressor wasnt kicking on. im just praying that it still needs a little bit more of freon and that there isnt a leak somewhere. or do you recon i re vacuum the whole system again and dump 19$ on new freon

 

i redid my a/c system yesterday and after 5 evac's we were still over 6oz short on freon tryed heating the accumilator and nothing there so then we pulled a vacuum for 20 min then recharged the 29oz it called for and the pressures were right but since by law you can only add freon to a system if it has a leak is to find the leak but i think mine is from when the body shop replaced the condensor and didnt charge it correct now i got 41 degrees out of my ducts

 

Did you pull a vacuum on the system for three or more hours you do this to get all or any moisture out of the system the long vacuum is needed to make sure its dry before you pump any Freon in.

I only did one hour and I was fine.

Also if you didn’t do this the dryer receiver will remove the moisture but slowly and not a good way to do this as then it will be used up and no good at removing moisture anymore its life span is gone in one year.

If you didn’t do a long vac pull the system may not run so well for a few days till the moisture is removed by the dryer.

 

3 hours is way to long for a 3cfm pump. 30 min top should be sufficient. im just gonna evac it again see if vac stays, then throw more freon in it and see what happens.

 

What temp did you have when you got those pressures Brian?

As a general rule of thumb the high pressure side should be about 2 1/4 to 2 1/2 times the ambient temp.
