I searched in the 2009-2014 threads specifically to determine how to drain the coolant from our 2010 F150, 4.6L engine, but I have found nothing definitive on a procedure to accomplish this. I bought the truck yesterday and I am giving it to my daughter and I need to get this done.

Typically there is a drain pet**** on the bottom of the radiator, but I have failed to locate it. I figured maybe I need to remove the lower radiator hose and drain it that way, but there is a specialized clamp/locking device that I do no know how to remove. Surely someone has done this and can give me some tips….

 

There's a petc@ck on the passenger side bottom corner facing rearward towards the engine on my 2009.

 

yep, found it late last night. I found it by looking outside of the frame on the passenger side. I was looking between the two frame supports earlier, that was why I couldn't find it.

Thanks for the help!
