Magnuson Owners - PSA - Check your pump - Edit: Never mind False Alarm

[DC3]

I had the intercooler circuit drained this weekend as part of my cam swap and learned my intercooler pump no longer works. I discovered the issue when I activated the pump to circulate the coolant and there was no sound. Through a series of diagnostic steps, I determined the pump runs for about 5 seconds and stops. I manually filled the line to ensure coolant, and I observed flow at the reservoir.

This could be inconvenient if not devastating on a hot day if you got into a long pull without the pump working.

The part number for the pump is 6007367-00-E, it looks like one that's used on the Tesla Model S.

I just installed the Magnuson and figured out my intercooler pump was not pumping as well. I first noticed when logging and saw excessive intake temps.
I took it out and tested it on a bench and found it turned off after a few seconds. I thought the pump was out so I ordered a new one. The new one had the same issue!

It turns out that the pump was actually starving for fluid and that it must have a protection mechanism that shuts itself off under
.

I primed the pump by “milking” the hose above the pump. I would then jump the relay and allow the pump to turn on and then it would shut off. Once I successfully primed the pump, the pump turned on and stayed on with the ignition as designed.
I’m now the proud owner of a backup pump. This pump can most easily be found by its common name “varimax intercooler pump” which looks to be used in many applications.

To jump the rely cut a short piece of wire and connect both red wires be sticking the stripped ends into the female blades. You should hear the pump turn on for a few seconds and turn off if fluid is not moving through the pump. Fluid movement can be monitored easily with a full reservoir and open cap. Try to milk the coolant through the pump and repeat. Once primed the pump will stay running and you can see the movement. This is easier than starting and stopping the vehicle as it is easier to hear the pump and you cannot confuse the vibrations from the running motor as fluid movement.

Well, that's embarrassing. I thought for sure I bled the air from the system. But low and behold, you are right. I even checked for flow in the reservoir and could see movement, I guess there just wasn't enough fluid in the line.

Thanks for sharing your experience.

It took me a week to figure it all out. Glad it saved you some trouble and money!

I love a story with a happy ending. Maybe one day I'll have on of those on my supercharger thread.
