Freeze plugs are small, cylindrical-shaped plugs that are used to fill the passages in an engine created by the sand cores. During production, passages are created in engines that allows for the removal of casting sand.

Can you drive with a leaking freeze plug?
Driving with a freeze plug leak is possible, but it isn’t advisable. If you must drive around with your freeze plug leak in your vehicle, ensure you maintain a relatively low temperature in your engine and ensure that it does not get too hot.
What happens when a freeze plug fails?
Freeze plugs are an essential part of your engine, because they keep coolant from leaking out. If you neglect a leaking freeze plug for too long, your engine’s coolant could potentially leak to a level where it can no longer effectively cool your engine, and cause it to overheat, risking extensive damage.
Do engine freeze plugs work?
Freeze plugs protect engines from frost-related damages. For example, a frozen coolant will expand and cause a crack on an engine block. However, Freeze plugs do not allow these cracks to occur but rather allow the freezing water to expand out the plugs’ passages.
How long does a freeze plug last?
I’d recommend doing it every three years or 60,000 miles – given the cost of the consequences. Tom: If you don’t have good rust inhibitors, rust will attack the weakest link in the engine block. That’s the freeze plugs – which are designed to give way if the engine freezes, preventing your block from cracking.
Can you patch a freeze plug?
BlueDevil Pour-N-Go is incredibly simple to use and will permanently seal a leaking freeze plug without having to drain and refill your cooling system or ever crawl under your vehicle.
What can I use to stop a leaking freeze plug?

Where is the freeze plug located?
The first thing to know is that the freeze plugs are located on the front, back, and sides of the engine. The front and side freeze plugs are accessible, but the rear freeze plugs are not. The transmission needs to be removed if you’re unlucky enough to have one of those leaking.
How do you tell if your freeze plugs are leaking?
Even if you don’t see a puddle of coolant underneath your vehicle, you may be able to smell it. Coolant leaks caused by bad freeze plugs will create a distinct odor. Coolant has a sweet odor. If you notice this sweet odor when inspecting the engine bay, you could have a coolant leak.
Why are they called freeze plugs?
The slang term “freeze plug” was derived many years ago in situations where the water in an engine block could freeze (due to plain water being used in winter rather than anti-freeze coolant). The expansion of the water as it froze would cause the core plug to pop out of the engine, leading to the term “freeze plug”.
Do freeze plugs need sealant?
Then prep the plug with some Permatex Form-A-Gasket #1 sealant. This product is designed for freeze plugs and other press-fit applications, as well as gaskets. Just a thin coating is all you need. You don’t have to use it, but you have a better seal if you do.
Can you reuse a freeze plug?
No – do not re-use it. The sides of a freeze plug are slightly tapered to become a press fit in the opening. Once the plug has been used, the sides have been bent in and it will not fit as tightly as it should. They are so cheap that it’s not worth the brain power to even think about it.
