How Often Your Radiator Needs to be Flushed

A radiator flush is a process of draining all coolant or antifreeze and replacing it with fresh coolants. Engines run incredibly hot and need some form of external cooling. Radiator liquid, in the form of coolant or antifreeze, is used to cool the engine. It's imperative to keep the coolant fresh and clean to keep the car from overheating and maintaining the radiator. A radiator flush is routine maintenance to keep the radiator healthy and should be performed on a semi-regular basis.

Over time, debris and other contaminants build up in the coolant system. Corrosion, rust, and other debris accumulate in the radiator and the surrounding coolant system. This debris needs to be removed, or you could end up replacing your entire radiator. Here's where a radiator flush comes in.

A radiator flush involves injecting cleaner, water, and new antifreeze through the coolant system to remove any harmful buildup. Directly draining the antifreeze or coolant will not remove all the harmful contaminants in the system. The system requires a deep flush to remove any old antifreeze or debris that will corrupt the new coolant. Other benefits of a radiator flush include removing rust from the coolant system and lubricating the water pump. Including the proper additives in the fresh coolant can also boost the performance and life of a vehicle.

If a vehicle is overheating, a potential solution is performing a radiator flush. There could be a leak in the coolant system, the radiator could be faulty, or the coolant could be stale. These are all issues that can be detected and resolved during a radiator flush. A coolant leak or loud engine noise could also signal it is time for a radiator flush. Keep an eye on the temperature gauge on the dashboard. Dangerously high temperature could signal that it is time for a radiator flush.

Radiator flushes should be performed every 1 to 5 years or as needed. If you have any questions or need a radiator flush we invite you to bring your vehicle into our repair shop today!
