weight is the operative word. Commercial techs have scales they use with the larger containers, so they can see that they added an exact weight. While that is not needed with Rover, as two 340 gram (12 ounce) cans are within the spec of 700 plus/minus 25 grams. A little must be allowed for loss in the lines. Don't turn cans upside down to squirt liquid in there, the compressor won't like it. You can make things go a little quicker by placing the can in a pan of warm water.

 

I was going by the instructions with the gauge. Essentially you point an arrow at the ambient temperature and then the minimum and maximum ranges (in my case, due to outside temp) show 45-55. Not very scientific.

 

That pan of warm water idea is great. I deduced that it was taking longer and longer for the pressure in the can to build up as the can got cold and it got closer to empty so I set it in the air flow from the fan behind my radiator (to the side); which seemed to help it recharge for another squirt faster.

 

No, I did not charge under vacuum; I removed it prior to charging. No bueno.

So what I am hearing is that I should start over. Replace the drier, replace the oil, pull a vacuum, and charge with 134a, approximately 2 bottles (12 oz. bottles). Is that the consensus?

 

"yup"!!

 

there is your problem, why would you dump the vacuum. you have to charge the system while its in a vacuum. just bring it to someone and spend the $100 and have it done right.

 

This is the best plan, especially if you don't have a GOOD vacuum pump, and a set of manifold gauges that will read both the high and low side of the system. There is a lot more information you can get if you can see both pressures.

Of course I won't lie, I did recharge my A/C in the disco with a quick charge single gauge thing I got at Wal-mart, when driving across the middle of nowhere Oklahoma, and my choice was sweat to death or do it halfway. I chose halfway.

 

It's not a money saver. I just like to figure things out myself (with the forum's help). For all of the mistakes I've made I'm sure I would have saved money using a pro. Also, I like the tools.

 

Done. It's at 35 degrees on LO/max fan at idle. Freeze a brass monkey on the highway. Thanks for all of the guidance, people!

 

If you are above 80 degrees out side, you pressure should run to about 45 on the gauge, 35 is when it is 65 to 70 degrees out.
