pool of antifreeze under truck
I noticed a small pool of antifreeze under my 89 f150. It looks like its coming from the right hand side of the block where a sensor wire is going in. A circular plug or some such about the size of a quarter. The wire goes into it.Is this a threaded plug?What do i have to do to stop the leak?By the way my engine is the 300 in line six.

either that, or they were leaking anyways.... my buddy has a el camino (i know its a completely different vehicle), but his freeze plug didn't give him warning or anything... it just completely blew out of the block.... it was 65-70 degrees outside to, so the coolant wasn't froze

The factory uses steel freeze plugs, they rot out over time. Replace them with brass ones, they're much better. I bought the freeze plug kit, came with everything and was only $10.
You can see where some were seeping. It wasn't bad to do. I removed the passenger front tire and then the inner fender well. You will have to unbolt a few things from it before it will come out. Then I removed the rear exhaust manifold, it was in the way of one of the plugs. Find a socket that just fits inside the plug and drive it into the block, then use pliers to pull it out. Coat the sides of the new plug with shellac and drive it back into the block, stopping at the same depth the old ones are in. I removed them all at once and hosed out the water jackets. I also used black RTV instead of shellac but am told shellac is what to use. Be sure to change them all, if one is leaking the rest aren't far behind.
