Okay, let’s not make any further delay and directly jump into the content because you need more details about the location to find it right away.

Where Exactly is the Chevy 350 Coolant Drain Plug Location?

As you already know drain plug is used for draining out the coolant liquid, which is why it is one crucial component of the engine cooling system.

The drain plug of your chevy 350 car engine is a built-in part with your radiator. To be more specific, you will find it at the edge of the bottom side of the radiator of the engine, exactly facing directly towards the engine.

One of the IFixit members clears this so well by saying-

“Location is driver side radiator tank, very low on tank almost at bottom, plastic 1/4 turn butterfly drain plug to be loosened to drain coolant. Word of warning, sometimes better to ease off/ loosen lower rad hose and drain rad/coolant this way, some drain plugs (being plastic and old break very easy, leaving half stuck in radiator tank).”

Not only in Chevy 350 car engine, but you will also find the drain plug at the bottom edge of the radiator in almost all car engines. So, if you are looking for the location of the coolant drain plug when the car is not Chevy 350, try to find it at the same location. 

As the drain plug is situated in the radiator’s body, it is also called the “radiator plug.” Actually, you will find the name “radiator plug” most commonly used rather than coolant drain plug.

While Looking for the Coolant Drain Plug Location, Do I Need to Find the Radiator’s Location?

The answer is a big yes. As you already know coolant drain plug is located at the bottom edge of the radiator; you must know the location of the radiator as well. Well, it is quite natural for you not to find out the radiator’s exact location if you have very little knowledge about car engines.

The radiator is one of the main components of the engine cooling system. Basically, the primary job of the radiator is to eliminate the excessive engine-produced heat. That is why, in almost every car, you will obviously find the radiator under the hood right next to the engine.

Why is the Coolant Drain Plug Located at the Radiator?

The radiator plays the most significant role in the entire cooling system of a car engine. In case you don’t know, I inform you that the radiator also has a small built-in tank to reserve coolant liquid.

In the entire cooling system, there are two places where coolant liquid is reserved: the coolant tank reservoir and the radiator tank. But, no draining-out facility is available at the coolant tank.

However, if you measure the horizontal position of the radiator and coolant tank, you can see the radiator’s location is comparatively downwards. That is why the location of the drain plug is at the lower bottom edge of the radiator so that while you are draining out the coolant, there is no coolant liquid left in the whole cooling system.   

Do I Need to Crawl Under the Car to Access Drain Plug?

Actually, it varies from car to car according to the formation of the engine and radiator. If the engine and the radiator have little space between them, then it will be pretty hard to get access with a hand. In such a situation, it is better for you to crawl under the car to access it.

On the contrary, if the engine and radiator have convenient space between them, it is good news; you don’t need to crawl under the car. You can easily access the drain plug by only opening the hood.

Frequently Asked Questions (FAQs)

How often do I need to drain out the coolant from the cooling system?

It would be best to drain the coolant liquid from the cooling system every two years or after driving 30,000 miles. That duration is for silicated coolant liquids. On the other hand, the duration can be up to five years or 100,000 miles for extended drain coolants.

How do you remove a radiator plug?

Usually, you need to use a wrench to open up the plug. However, if the plug doesn’t have a square-shaped head, you will need a vise-grip on the plug. Now, start turning it counterclockwise. Use your hand to remove the plug when it is almost about to come out entirely. Then connect a pipe at the radiator’s opening to avoid the coolant splitting.
If your machine and radiator don’t have enough space between them, perform the removal process from underneath the car. 

When shouldn’t you do a coolant draining out?

When the car’s engine is hot after a long drive, at that time, you should not perform the draining out of coolant. If you try to drain out coolant when your car is hot, the hot coolant liquid may spill out at bare hands or any other body parts and cause severe burning.
Likewise, while draining out from beneath the car, spilling out of the boiling temperature like coolant liquid will bring out a devastating result.
