How Do You Drain Coolant from Engine Block?

Assuming you would like a blog post discussing how to drain the coolant from an engine block: “How do you drain coolant from engine block?” There are a few ways that you can go about draining the coolant from your engine block.

The most common way is to use a radiator flush kit, which will allow you to quickly and easily flush out the old coolant. You’ll want to make sure that you follow the instructions carefully, as using too much pressure can damage your engine.

Another way to drain the coolant is by disconnecting the hoses that lead into and out of the radiator. This will allow all of the fluid to drain out, but it’s important to be careful as there may still be some residual pressure in the system.

Once all of the hoses are disconnected, open up the petcock at the bottom of the radiator and let everything drain out.

Finally, if you’re comfortable working with tools, you can remove the water pump pulley and disconnect the hose leading to it.

This will allow all of the coolant to Drain out completely, but again, be careful as there may still be some residual pressure in the system. Once everything has been drained, simply reconnect everything and fill up with new fluid.

How Much Coolant Remains in the Engine Block?

Assuming you are talking about a typical engine cooling system: The coolant that remains in the engine block is referred to as the coolant reserve. This is the amount of coolant that is left in the system after the engine has been turned off and cooled down.

The coolant reserve is typically about 2-3 quarts (1.9-2.8 liters).

Does Coolant Flow Through the Engine Block?

Yes, coolant does flow through the engine block. The engine block is where the cylinders and pistons are located, and it is also where the crankshaft is located. The coolant helps to keep the engine cool by absorbing heat from the cylinders and pistons.

It then flows through the radiator where it is cooled off by the air passing through it.


Most cars have a coolant drain plug on the engine block. The location of the drain plug varies depending on the make and model of your car. However, it is usually located near the bottom of the engine block on the passenger side.

If you’re unsure where your coolant drain plug is located, consult your car’s owner’s manual or a mechanic.
