Full Version: Test cold start valve
Looking for tips on how to test the CSV before I spend $$ to replace it how do i know it's bad...And best way to get those two Flat-Head screws outta there if I have to replace it. Thank you
direct 12 volts. maybe attach a rubber hose on one end to blow air to test the flow. After applying 12 volts, the element inside should get warm/heat and makes the valve close. when cold and blow air on one side, you should feel the air from the other side. offcourse when valve close, you can feel lesser air (i think not totally close but u will notice less air)

Ah...this tests the AAR, not the CSV.
You don't need a cold start valve in San Diego. If you aren't sure it works right, remove the hose and plug it. Disconnect the wiring. Continue driving.
