How to Flush the Coolant in a ’93 Chevrolet Truck

40

Chevy recommends that you change your engine coolant every 30,000 miles or every two years, whichever comes first. Over time, the chemicals that protect your engine’s cooling system start to break down and actually cause damage such as corrosion and clogging. When you flush your radiator, it purges the radiator and the engine block of all contaminants that could cause premature engine failure.

Things You’ll Need: Pliers, Drainage containers, 8 gallons Tap water, 12 gallons Distilled water, 2 gallons Coolant

Instructions

  • Drive your 1993 Chevy onto a set of front end raps to give yourself more room to work under the truck. Set the parking brake.
