Hi All,

My A/C is not that cold. I want to add a can of 134a. On the passengers side in the engine bay there is a silver cylinder with a fitting on it. I know it is for the a/c because of the directions on it. Is this the low pressure container? and is this where i put the freon in?

Thanks!!!

I believe that is the low pressure side. The low and high side connection have different size threads (R12) and couplers (R134a) so you can't put it on the wrong side.
