Coolant Flush


Coolant Flush

A flush is needed every 2 to 5 years, depending on the manufactures recommendations. Today we’re going to talk about coolant flushes so you better understand the complete maintenance cycle for radiators and engine cooling systems. With this information, you can protect your car from heat damage that can result in extremely costly repairs. Without it, you may find yourself stranded by the side of the road or, worse, left financially by auto repair bills.


Radiator, coolant, fans, thermostat, and a few fans keep the engine from overheating while it explodes fire inside itself. Without engine coolant fluid to properly move heat away from the engine, it would get too hot for the oil, which would lose its fluidity, dry up, and add to the overheating problem. The issue cascades further and further until one day, your engine blows up, and y,y, and you’re stuck looking for a new car.

Don’t let this happen to you. At least it would be best if you got a coolant flush every two years or 30,000 miles. Suppose you drive more frequently or under more challenging conditions like off-road or load-hauling vehicles.

An additional perk of the coolant flush process is that it helps wash away grime and small amounts of rust built up over time. And the engine conditioners added in help prevent them from building up in the future. So there’s a significant cumulative effect on the health of your engine from a Chico coolant flush service.


The video above shows the coolant we pulled out of a 2001 Ford V10 (no, it’s not coffee in that bottle, it’s filthy coolant). You can tell something’s wrong by the smell; in this case, it smells like fish. The most obvious signs that it’s time to get a coolant flush include the following:

  • A sweet smell comes from the ethylene glycol burning out of the antifreeze mixed in with the engine coolant.
  • The engine temperature gauge reads high and noticeably faster than it did before.
  • It’s been two years or 30,000 miles.


Here at the shop, we use a flushing machine, and the process is slightly cleaner, faster, and less complex. Below is a way to do the same process at home yourself. This style of coolant flushing saves you around $140 if you choose to do the flush Chico style yourself.

First, we ensure the car hasn’t been running recently, so we don’t burn ourselves when we open the radiator (pro-tip). Then:

  1. Pull the drain plug and drain the coolant.
  2. Fill the radiator with water, then start the engine and cycle it.
  3. Add a chemical engine flush to clean the system.
  4. Flush out the plan.
  5. Add coolant and distilled water mixture.
  6. Add engine conditioners if you wish.
  7. Finally, dispose of the old fluids and chemicals safely and correctly.

Of course, some details are missing from the process, but that’s the gist. If you’re interested in learning more, check out this short video from ChrisFix, which explains the flush process with a visual aid to boot:


Getting a flush is easy to forget; many these days don’t even know they need them. On the other, you learn how coolant flush works and when you need to do them so you won’t be left stranded on the side of the road, confused about how this happened to you. Remember r e, every two years/30,000 miles, or if you suspect engine cooling system issues.
