Draining Engine Coolant

WARNING: This page is about a different car, the 2007 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove engine undercover, using power tools.
  2. Open radiator drain plug at the bottom of radiator and remove the radiator filler cap. This is the only step required for a partial cooling system drain.

  3. If removing the heater core, remove the upper heater hose from the engine coolant outlet and apply moderate air pressure of 15 psi (103.46 kPa, 1.055 kg-cm2 ) maximum for 30 seconds into the hose to blow out excess coolant from the core.
  4. For a complete cooling system drain, remove the reservoir tank and drain the coolant, and then clean the reservoir tank before installation.
    • Do not allow coolant to spill on the drive belts.
  5. When performing a complete cooling system drain (to remove the engine or for engine repair), remove the cylinder block front drain plug and the cylinder block RH drain plug.
  6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.
