What are the Benefits of a Radiator Flush?


To avoid unnecessary costly repairs you have to maintain your vehicle regularly, it also helps to boost engine performance. Most drivers know the importance of oil changes and the alignments for cars to run smoothly. The radiator and coolant flushes play a major role to keep your vehicle perfect.

Coolant is responsible for regulating the water inside the radiator. It prevents this water from freezing over in cold temperatures and from boiling in hot temperatures. Coolant will provide an essential lubricant in the water pump and other significant components. 

Today’s modern vehicles typically have cooling systems that are designed to last up to 100,000 miles. During a radiator flush, it can pump up to 5 gallons of antifreeze through the cooling system. All the dust, debris and contaminants will be removed during the service.

Radiator flushes offer several advantages, below are five major benefits. 

Removes Rust and Scale Deposit 

If you fail to maintain the system regularly, the rust and scale deposits will build within the radiator. Flush will remove the deposits which will be pushed out with the antifreeze. It’s very important to clean the debris because it can lead to overheating or damage the radiator.

Lubricate the Water Pump 

The additives in the coolant lubricate the vehicle’s water pump. This will increase the life of the water pump.

Removes Contaminants 

The purpose of flush is to completely drain the system of the old antifreeze. If you’ve found any contaminants into the system it will be flushed out as well. The additives in the coolant may lose anti-corrosive properties over time which leads to the build up of particles. A radiator flush will remove these particles from the system.

Inspection of System 

Use pressure tests to check for leaks in the system. During a radiator flush service, a complete inspection will be conducted.

Protect Against Rust and Foam

The new antifreeze will have additives that prevent rust build up. It will also prevent foaming in the system which ensures efficient operation of the system. 

How Do You Know When You Need a Radiator Flush?

There are several signs that may indicate your vehicle needs a radiator flush. If your car overheats, there might be either a leak in your coolant system or that the coolant might be contaminated. 

If your coolant levels are full even though your engine has overheated, the car’s radiator can prevent your car from overheating. Other signs that a radiator flush is necessary include engine noise,  debris in your coolant, and an odd smell, coolant leaking underneath your car.

How Often Should You Perform a Radiator Flush?

Experts say that every three to five years you should do your radiator flush. If you own a new car, no need to do a radiator flush for at least a year. Unless you get to notice the signs to perform radiator flush, you can wait or you should do at least every 30,000 miles. Note your owner’s manual recommended schedule
