recharged the AC in the PT...this stuff here makes it easy peasy...
Stuff is a little on the $$ side at $40 a can at Advance, but I used coupon code RETMENOT123 and got it for $32.43 out the door.
Easy to use too...turn engine on, attach the quick connect to the low side port, turn dial so the arrow in the middle of the V is pointed to the appropriate AMBIENT air temp...turn AC on to MAX and check pressure...if low, add freon by simply squeezing the trigger til the gauge needle is in the green zone between the V mark.
Took me all of 10 minutes...literally.
