A/C Pro --fix in can!
What more can I say!
Why you guys resort to this remedy is beyond me!
Their slogan colder air!
Makes me laugh for starters and as for the oil compatibility in the can, plus there is often a stop leak you are asking for trouble like a failed compressor.
Something to consider!
Often overlooked by DIY'rs is the need to record the on off time against specs!
Excessive A/C clutch cycling times and slip causes heat to build up in the pulley and causes eventual seizure of the clutch assy, let alone damage to the shaft gland seal!.
A mix of wrong or excessive oil, often found in impure A/C refrigerant from an unknown source (WTF is in there???) and sealant in the can is a sure fire recipe for an expensive wallet flush!
Things to remember!
