In this video, I show you the exact process to properly drain the engine coolant on a 2011-2016 Chevrolet Cruze (first-generation model). Whether you are prepping to replace a leaking water pump, swapping out a cracked thermostat housing, or just performing a routine cooling system flush, getting the fluid out cleanly without making a huge mess in your garage is the essential first step to any successful cooling system repair.
Common reasons you need to drain your cooling system include:
- Performing a preventative coolant flush and refill because your factory antifreeze has aged, turned brown, or lost its crucial corrosion inhibitors.
- Prepping the vehicle for major component replacement, such as a new radiator, heater core, or the common oil cooler housing gaskets.
- Fixing a cross-contamination issue, such as oil leaking into the cooling system, which requires a complete drain and system degreasing.
Safety First: Engine coolant operates under high pressure and reaches boiling temperatures that can cause severe skin burns. Never, under any circumstances, attempt to loosen the radiator drain petcock or open the surge tank reservoir cap until the engine has sat completely shut off and is completely cool to the touch. Always place a wide, proper drain pan directly underneath the lower radiator corner to catch the fluid, keep clean rags nearby for quick cleanup, protect your hands and eyes by wearing durable gloves and safety glasses, and stay fully focused and attentive throughout the entire process.
