What would cause a freeze plug to come out?
Considering this, what causes a freeze plug to leak?
In some cases, as the water freezes and expands in your block, the freeze plugs will push out relieving the pressure of the freezing water and partially draining your cooling system. However, freeze plugs can also start to leak over time simply due to the heating and cooling cycles of driving your car.
Beside above, how much does a freeze plug cost to replace? The freeze plugs are made of very thin metal. And if they rust, they leak. Ray: To replace the freeze plugs, you have to remove the engine. That's why the bill is $1,000.

Can you drive with a bad freeze plug?
Yes, the engine will run but will have a coolant leak. A freeze plug is a thin metal cap pressed into and engine blocks coolant passage. The engine will still run as long as the coolant level is topped up. Since a freeze plug is the lowest point of the engine, the coolant would likely leak out very quickly.
