What is a coolant flush?

An engine coolant flush, more commonly referred to as a radiator flush, or system flush, involves the draining of old coolant, followed by a rinse with specialized systems cleaning liquids, and a fresh refill. Gradually, coolant that’s aged begins to fill up with rust, scaly deposits, and lots of other gunky materials that can severely restrict radiator capacity, destroy the ability to transfer heat, and as a result… overheat and damage the engine.

In this process, technicians will:

• Remove the old coolant from the radiator and engine block.
• Add a specialized flush to the system to dissolve rust and other sediment.
• Remove the flush solution including the dissolved debris.
• Using a flush, refill the system to the manufacturer specifications with new coolant that was mixed prior.
• Inspect the entire system for and bleed any trapped air.
• Completing this service regularly will guarantee that your engine remains effective, and is able to cool appropriately.

Dealership vs. Corner Store: What You Are Paying For?

Pricing Difference

Local shops and dealerships differ in more than just service pricing. Unlike local shops, dealerships offer higher, more knowledgeable labor because they have more certified technicians. The dealership’s overhead costs which include specialized money, also drive prices up.

In contrast, local shops are more affordable because they use aftermarket fluids and aftermarket parts which lowers the engine coolant flush cost. Although independent mechanics may provide more flexible service, they tend to have lower service quality.

Quality of Fluid

The dealers often utilizing OEM coolant that meets your manufacturer’s specifications exactly. This means that it’s compatible and will last, but at a premium.

Local stores might have some generic coolant that works in most cars. Although generally safe, mixing coolant types may cause chemical reactions, which will result in gel formation and/or clogging if there is no complete flush.

Service Thoroughness

Many times dealers also do a complete vehicle inspection when they do the coolant flush so they look for related problems that can help prevent future problems. They may also perform any technical service bulletins (TSBs) or vehicle recalls during the visit.

Local stores might not do all of that thorough of a check-up but do perform some basic flushing services.

Convenience and Speed

Dealership service appointments can also be more difficult to book, particularly at top brands or busy locations. Local garages or quick lube chains provide quicker appointments and sometimes same-day service.

When Should You Get an Engine Coolant Flush?

Many car makers recommend a coolant flush every 2 to 5 years, or 30,000 or 50,000 miles, so check your owner’s manual. But check your owner’s manual for precise intervals.

You might require a flush earlier if you experience:

• Engine overheating
• there is a sweet smell and puddles of coolant under the vehicle
• Rusted or dirty coolant in sediment in the reservoir
• Heater not working effectively

If you stay long on the flush, it can elevate corrosion and get your radiator or engine damaged.
