Thanks guys! I didn't realize that HF had giant wrenches like that, and at that price I could break them a few times (and very well may!) and still be ahead. It sounds like draining will probably be the answer and to respond to someone, unfortunately yes, I've changed it recently... I gotta do what I've gotta do.
@Tinkerer ? That's a good call!
As for the HF wrenches, I would buy that set without a second thought if I had an application for them. I have a buddy that earns a living with HF tools as a mechanic. He has mostly the Pittsburg line for wrenches, ratchets, sockets, etc. His 2 cents was that they're every bit as good as a major name brand for
basic hand tools. He does own some snap on, but it's minimal.
Most recently, I've bought Sunex brand tools off Amazon for some specialty items like crows foot flare wrenches and stubby, large size wrenches, also a set of 1/2" drive, Cr-mo impact sockets. I'm only fixing my own equipment so I cant justify buying major name brand tools. So far, the Sunex tools have done everything I needed in recent repairs. I also have some cheap Taiwanese made wrenches in a roll that I use when I need to make a custom wrench, bend it, shorten it, etc. Like $25 for a 15 piece set. They've also worked well for getting at hard to reach hydraulic lines.
