I've had to do it to a couple of older cars I own. I know they are a closed system, but do most of them need to be recharged sooner or later?

If ya need to recharge YOU HAVE A leak refill with DYE and find the leak

Havent seen one yet that wont leak over time. Too small of molecule size and too much pressure to contain infinately with so many junctions in the system. Its just how it is.

My '85 Toyota p/u blows cold and it's never needed to be recharged, same with the '87 Jetta I had up until '08.

My wife's '97 Explorer and my '00 Dodge CTD OTOH have both required recharging.....

R-12 vs R-134 I believe.

Yes as a general rule automotive systems have many potential places to leak from. The
Compressor shaft will always leak a tiny bit. The amount can be so small that you will never notice. The fridge does have a fully soldered and welded system that won't ever leak if properly built.

Don't worry, the HT6 will fail soon, just replace it with a Sanden.

Google HT6 belly leaker.
