    I pinned my crank - drained coolant - had 1/2 gallon come out - trying to fill from overflow tank - not working well

    What am I doing wrong?

    filling the engine cooling system you will need to remove Allen plug by thermostat housing to allow the air to escape the cooling system. This should allow you to add the coolant you drained back into the coolant bottle.

    Yes - it was inter cooler coolant I was asking about

    I drove the car around my neighborhood and it moved some more coolant through the system - now missing just a few ounces but reading full - I'll drive some more and see what happens

    PS don't open bleeder on back of intake where the coolant lines go in - I lost another few ounces as I opened it - onto the exhaust - tsssssssss......

    If he is filling the supercharger cooling system he needs a pressurized air operated vacuum generator. (Airlift air bleeder tool). Supercharger cooling system should be completely drained first.

    Huh? I took my cap off the other day, topped it up with distilled water. Does it need to be more difficult?

    You had me mildly concerned. On the phone in my ear was a very experienced Service Manager/Mopar Nut/friend. We are just attempting to get this pest of a idiot chime to stop after quick acceleration to stop saying it is low. I may have a bad cap. Looked and it was low past the cold line. It was full last year. So we are watching now.

    I ran mine a little, shut off. Cracked the bleeder and let the air escape. Repeated until just coolant came out, took maybe 3-4 times. That's what the bleeders are there for and why the coolant reservoirs are the highest part of the cooling system-helps air escape into the reservoir.

    So the Super charger bleader is on the back of the intake?

    Look where the 2 coolant lines go into the back of the supercharger. It's on top of the housing, 2 piece brass fitting. 7mm cracks the outer loose.

    This thread is nearly about a year old, so I may just be beating a dead horse. If that is the case then I apologize and just ignore the following text.

    The Supercharger coolant is independent of the engine coolant. 2 separate circuits. You can not fill one and expect the other to also fill, you must fill both if they are both low.
