    Alternative to coolant vacuum fill tool?

    Guest-only advertisement. Register or Log In now!
    Just installed a PLM cooler system. The system took in nearly an additional 2 gallons of G12/water but can't seem to get all of the air out. I don't have access to an air compressor or I would have used a vacuum filler tool. Made attempts to fill and bleed using the screw atop of the supercharger but it doesn't seem effective.

    What's leading me to believe the system is not running optimally is due to the fact that the new HE is pretty cool to the touch after runs but the supercharger itself is quite hot. Also, when I do opne the supercharger bleeder screws, no coolant flows out. I can see coolant down the hole but nothing flows out.

    Anyone have alternatives that are effective?

    In addition to the two bleeder screens on the SC, there is a bleeder hose for the main cooling loop that goes into the fire wall. Although the systems are semi-divorced, it's possible that you need to bleed the main loop as well.

    Fortunately, I had a vacuum fill tool, so I don't know how much air in the main loop affects the SC loop.

    I don't know if this helps, but search for "COOLANT FILL and BLEED" on this thread. In that section it talks about how to bleed the system:

    I forgot to mention when bleeding the SC loop you need to have the engine over 2k RPMs for the pump to work.

    The SC aftercooler should be pretty cool to touch,the temps of the coolant will only be in the 60-70*C kind of area.
    You could also do the pump mod to aid with bleeding as it will be running the pump at tick over then .

    This.. And bleed the heater core with the heater on. Just make sure you have some rags under.
    You can also continue to open the coolant reservoir and screws throughout the next few days as air bubbles travel and get trapped up top.

    You can also feel the bubbles travel when you touch the hose to confirm that you still have air in the system.
