How do you flush a car engine?

What's the best way to flush your car's engine? My car is due for one. I think I can do it on my own, but I don't want to damage anything.

“The short answer is you shouldn’t flush your car engine.
Instead, most experts say that you should use an engine flush additive. Here’s how:
  • Pour the engine flush additive into the oil port and close it.
  • Then, let your engine idle for 15 minutes. This will help remove any sludge and deposits without actually flushing your crankcase, which can damage your engine.
If you decide to actually flush your engine, you may void your car warranty. Proceed with caution.
Since you clearly care about keeping your car in good shape, now’s the perfect time to evaluate your car insurance. Get great insurance at a great rate—the Jerry app makes it quick and easy.
