Bosch intercooler pump

[Ark :D]

Hello guys,

Does anyone recall what fuse protects the Bosch intercooler pump on SS/TC builds? I watched the build videos for a good hour and a half last night and was unable to find it .... but I did find that they recommend using the pink wire at position B2 on the gray fuse box connector.

Thanks in advance.

Think you have a blown fuse or something?

Assuming I'm not oversimplifying, have you tried probing for continuity from the pink wire to your different fuses in the box?

I was doing some spring prepwork on the car last night and noticed that there was no coolant visible in the intercooler loop (I have a T connector I can see through in the loop). I topped the loop off, it only took a little bit ... and then I thought to check the flow as well. With key-on, nothing was flowing. I didn't have enough time left last night to do much troubleshooting aside from pulling a couple fuses to check visually, but I did apply 12v and ground to the pump directly and it didn't run (it did make a quiet click noise, though), so I suspect the pump died at some point.

Next time I get some time in the garage, I'll start probing.

Eh, yeah maybe your pump just crapped out... I have worried about that at times with mine. Have wondered if there was air in the system or simply just a bit low could it drastically shorten pump life, instinct says yes but not sure.

With the hours that the pumps have to run, I would suspect it is the brushes that go out. I got a take off kit from a SS/SC and on bench inspection the pump didn't work, took apart and saw that the brushes were gone. Replaced brushes and all good.

Hmm, interesting that this wind block didn't keep a good portion of the engine bay air from spilling forward? The side panels with the upper extension are nice - and the plexi is a great touch!

Yep. Easy fix to replace the brushes, just like a (older) starter

Good to know. Bit of a different animal, but I have fixed a dremel replacing the brushes once before.

I did find out that wire B2 on fuse box connector X5 corresponds to a 10A fuse, "ABS 2", in the engine fuse box. However, that fuse is not blown, for me. The pump isn't bad either ... I tore it out of the car and ran it with 12v and a different pigtail that I had laying around, and it fired right up. So at this point, my intercooler pump wiring seems to be broken. The ground is good, but I see no voltage on the + wire.

I got around it by running another +/ign on wire from another unused circuit. Maybe one day I'll troubleshoot the existing wiring run, .... or maybe I'll just seal the old + wire end and call it a day.

Resurrecting this thread a little. I had DF do my harness modifications and the stock water pump connector is left on. What is this I keep hearing about a pink wire under the fuse box? Do I need to worry about that?

In the SS/SC, the intercooler pump plug is built into the harness from the factory. A key on power source is added for the turbo goblins. (Pink wire)
If it’s there just coil it up and shrink wrap the end until you find an alternative use for it. I added it into my harness as a future option for something.
If it is not there, do not worry about it at this time.
