If you have no other option, you may be driving with a faulty freeze plug. Freeze plugs rarely fall out or fail completely, so they cause slow leaks. As long as you keep your engine coolant full and your engine never gets hot, you could be limping your car along with a leaking freeze plug, although we never recommend it.
BlueDevil Pour-N-Go is incredibly easy to use and will permanently seal a leaking freeze plug without the need to drain and refill your cooling system or ever crawl under your vehicle.
On average, replacing an antifreeze screw costs between $200 and $400. However, removing a freeze plug, which requires the mechanic to jack up the engine or transmission, can cost anywhere from $900 to $1,800.
Freeze plugs are an essential part of your engine as they prevent coolant from leaking out. If you neglect a leaking freeze plug for too long, your engine’s coolant can potentially leak out far enough that it can no longer cool your engine effectively, and overheat it, causing extensive damage.
You will need a flat-tipped screwdriver and pliers. You should also use a flathead screwdriver to drive the connector into the hole. Then you need to use locking pliers and a socket wrench to slide it into the engine. You can replace an antifreeze screw by disassembling your engine.
If you’re looking for a leak stopper, BlueDevil Pour-N-Go Head Gasket Sealer gets the job done. BlueDevil Pour-N-Go Head Gasket Sealant is a particulate-free sealant that won’t damage or adhere to anything else in your system other than the leak. It’s permanent and guaranteed.

In some cases, when the water in your block freezes and expands, the freeze plugs are pushed out, releasing the pressure of the freezing water and partially draining your cooling system. However, freeze plugs can leak over time simply due to the heating and cooling cycles of driving.
The labor required to simply remove and install the transmission is 4.5 hours plus an additional labor hour for the one freeze plug on the back of the engine and an additional 1/2 hour for each additional freeze plug. Expect approximately 6 hours of labor plus all required parts and fluids.
The first thing you need to know is that the freeze plugs are located on the front, rear and sides of the engine. The front and side freeze plugs are accessible, but the rear freeze plugs are not. The transmission will need to be removed if you are unfortunate enough to have one of these leak.
Replacing freeze plugs is not difficult, but with the engine in the vehicle, they can be very difficult to get to. If you are unable to replace the connector in the vehicle, you may need to visit your local NAPA AutoCare Center for assistance.
Core plugs, also called freeze plugs or Welch plugs, are used to fill the sand cast core holes found on water-cooled internal combustion engines.
