Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good morning and welcome to JustAnswer!!My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.
Are you referring to the freon as the A/C cooling system? And since it passed a vacuum test then I would recharge it and see if the a/c works and if it doesn't then let me know what pressures you have at idle and I will tell you what is wrong..
When I replace heater cores I recover the freon and pull the dash, then when it's back together I vacuum the a/c system and charge it with freon. You don't have to fill it with freon to run the vehicle, you just won't have any a/c. ALso there is no test needed to be done before refilling with freon..
I hope this helps you and in the future feel free to request me for all your Chrysler-Dodge-Jeep needs..Have a great day,Brad
When you don't have any freon in the system and are planning to charge it then you first need to vacuum test the system to make sure it will hold a vacuum before installing freon and it leaking out.. If it passed the vacuum test then it doesn't have any leaks and it's fine to go ahead and charge the system with freon...
