    EP3 Coolant change

    I've searched for a while now and still can't find a DIY on here for a coolant change on the EP3. If there's one on here, please point me in the right direction. Thanks in advance!

    1) Lift front of EP. Place jack stands
    2) Remove splash guard
    3) Turn plug at bottom of radiator to drain coolant
    4) Close plug/Fill coolant
    5) Turn on car to circulate coolant.
    6) Turn heat on high to circulate coolant and remove bubbles from heater
    7) Fill radiator as the bubbles come out
    8) Squeeze various coolant hoses to help get bubbles out.
    9) When you're fairly certain all the bubbles are out, replace radiator cap.
    10) Check coolant reservoir.

    If car overheats, you didn't get all the air bubbles out. Re-do steps 5-10 again.

    If you have kpro, you're ECT should be in the 180's.
