Changing Engine Coolant
Changing Engine CoolantWARNING:
^ To avoid being scalded, never change the coolant when the engine is hot.
^ Wrap a thick cloth around cap and carefully remove the cap. First, turn the cap a quarter of a turn to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
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 soil 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.
^ If contaminated, flush the engine cooling system.
