i need to know if 3.0 v-6 engines have frost plugs?

Question

i had a anti freeze leak an thought i was the water pump it wasn't but i located the source but not sure what it is it's located back by the firewall about the middle of the engine down about the engine block there is a orange wire or cord coming from it, it's round and seems embedded in the side of the engine it seems like the old frost plugs of yesteryear if it is a frost plug should a professional replace it or should it be easy for me to replace it.

Answer 1

If that engine has an iron block, it'll almost certainly have core plugs in it (they never really were meant to protect the engine from freezing; their real purpose is to help hold the engine tooling together in the foundry). If you have enough room to get a hammer on it, you should be able to swap it out - if not, I'd let a pro handle it.

Answer 2

"Freeze Plugs" are not what you are describing. These do not stick out from the side of the engine and they also do not have things like wires attached to them. What you are describing sounds like an engine block temperature sensor, oil pressure/temperature sensor, or oil quality sensor. It could also be an engine block heater as mentioned by someone else. If this is the case it should be able to be removed, cleaned and sealed back in place with either Teflon tape or high temperature RTV Gel. I recommend finding a book describing your vehicle and identifying the part before you try anything.

Answer 3

By "Frost Plug" I assume you are referring to a block heater. If that is the case, it has managed to work its way out of the block spoor hole.
If you can get to it with in reason, you could replace it with a mechanically expanding plug, constructed of either rubber (less expensive, but more difficult to properly align) or copper.
The latter is available manufactured by Dorman, and are very sturdy.

Answer 4

They are called freeze plugs and yes they can leak coolant
