Petcock
Hello.
When I drain the coolant of my 1937 v8-60, i just pull one of the lower radiator hoses. I have 2 petcocks on the engine block but they seems to be stucked and I have not dared to use force on them. As the picture shows, they have not been used for years. Is there a trick to free them? I guess I am just supposed to turn the paddle on the top, not the nut on the bottom? |

Re: Petcock
sometimes they have to be taken apart,cleaned and lubricated with cock grease, a tube of it is $$ but enough to last a lifetime, Langs model T parts sells it.

Re: Petcock
i would bet that they are plugged up with rust and mud, might be more than you want to get into when you get started.

Re: Petcock
Might be better to simply replace with brass pipe plugs. Easier to get plugs in and out with wrench than turn a handle in that location.

By spraying a premium quality penetrating oil on your stuck bolt, you can reduce the amount of torque you need to apply by as much as 50%. |

Re: Petcock
That is the 48- style pet cock first offered in 35. I too would not use it for many of the reasons above.

Re: Petcock
be careful trying to remove the petcocks, I have seen more than one that broke off and also have seen cracked blocks from trying to remove them

Re: Petcock
Thank you for all your response and tips, you are the best😊 I guess I just leave them alone , and just unhook the radiator hose . I am having trouble getting my newly overhauled water pump tight so I guess I have to drain it again🥲🥲 The v860 pumps are tricky…

Re: Petcock
Be veryful careful not to strip the threads re: water pump installation. Don't overtighten.
