Plastic Cock ? - antifreeze

Thought might get some attention with title. Just changed antifreeze - plastic valve (cock) very hard to get started - I was afraid I would break it being cheap plastic - used a pair of pliers - CCW - QUESTION is there a tool and or method that works easily. Thanks for any reply.

 

If you think it’s going to break, pull off the lower rad hose. It makes a mess usually but at least you don’t have a broken cock

 

22mm socket or wrench.

 

Thanks - saving a broken cock is important !

 

I've just used channel locks on mine because mine's hard as well. Can't do it by hand, at least not until it's pretty much all the way open.

 

Thanks - I'm going to try it - just curious - how did you discover a 22mm would work ? Thanks again for the rely.

 

I used a 13/16 spark plug socket

 

I believe Bishop is master toyota tech. Fantastic having a guy with that kind of knowledge on the board.

 

Good 2 No Thanks.

 

Thanks - I'll try it.

 

I have the special sockets for this, but I can't remember if they work on a Tacoma! Some drains have a gusset which blocks access to them.

And I thought I had every gadget there was. Petcocks can be a pain. I usually get them open with locking pliers.

 

When those fancy sockets don't work I'm forced to get primitive and use a slip joint Channellock plier like the 526

 

Thanks for the link - I already have a 22mm and a 13/16 so I'll try those B 4 I spend $$ but the look interesting. Thanks again.

 

I used pliers too but I have a 4 banger and there is a bar in the way that's why I posted this - happily surprised at all the response. Thanks everybody.

 

Lol. You said plastic cock..

 

I need to take a cutoff tool and cut a perpendicular slot in the center so they'll always work
