I just wanted mainly to see if the I/C pump wood run with just the key on after shutting the car off after the pump was running. I'm heading to town now to get some parts to build a circuit to get the pump to run anytime my fans are on.
Great test Steve! - The only variable left to discover is how the pump reacts (and you have the LED and a IC coolant gauge to observe) - when the IC coolant is warm/hot or at some pre-set temperature. You might need to take it out and run that SRT hard.
I thought when my car was sitting on the dyno between runs (hot hot hot) and they left key in the "ON" position - I squeezed one of the IC hoses and felt the coolant flowing. With your test - the engine running at high rev's and cold IAT's - the relay may have signaled the IC Pump on in anticipation of what's to come...
Thanks for the heads up PM - I am pulling the front bumper today to install the Johnson pump and do a slightly different mod to the HE. - But the phone just rang and a part I ordered for my motorcycle is in - so a quick detour before I start.
