Where to purge AC to Remove?

[DeadSpool]

Blew a ring so tearing out the engine was we speak, where’s the best place to purge the AC system? There’s a black cap near the rad or the blue one near the valve covers.

The smaller one is the low side, the larger the high side. Both will have Schrader valves. With the engine off pressure will be equalized so it makes little difference which you use.
Moot point by now I'm sure but you really should recover the refrigerant, not release it into the atmosphere.
When it's time to recharge the system be sure to vacuum it down and add refrigerant by weight according to the under hood label.

Are modern refrigerants an issue to release to the atmosphere? I know the old R-12 stuff was, but I think it's fine with the R-134A.

With R-12 it's a serious fine to release it to the atmosphere, but there's no such issue with R-134A.

It definitely is an issue! Not sure if you are fined for R134A...

That was the reason R-123A was replaced with R1234YF in Europe. So far all refrigerants are pretty dangerous to the environment and can even be poisonous (R1234 when it comes in contact with hot surfaces (cat) can become very dangerous).

There is no requirement to contain it, or reclaim it. The OP can release it and refill it, no problem.

Lots of things in cars are dangerous. Let's not freak out over R-134A, it's pretty benign.

ETA; OP is in Canada. You better check your laws OP.
