ACD Pump disconnect for winter
ACD Pump disconnect for winter
Ive found one thread concerning this, where only one member gave their 2 bits. Can I disconnect it for winter without any damage to my TC or any thing else? Any one know for sure? were talking -30 degree celcius weather here.
It will definitely cause you to have an open center and open rear (which is pretty much exactly what you don't want in winter). I haven't really thought about whether it will cascade back and shut off the type-1 and -2 traction control. I suppose I could test that for you this afternoon. But the real question is why you would do this. Thick fluid is not what kills most pumps. That was just a theory from Mitsu that was later shown to be wrong in most cases. What kills the pump is corrosion and, if anything, having the pump remain idle all winter will make this more likely to happen.
because the main evo/ralliart guy at my dealership told me that he's run his car in every canadian winter since 08 and he unplugs his and its fine. i just want to know what to unplug? just the power supply or the solenoids?

What?
Leave the fluid alone unless it has turned brown. If anything, old fluid has lower viscosity, so if you're worried about the motor when the fluid is cold, then you want old fluid, not new. But since the real issue is corrosion from the outside-in, the age of the fluid is almost completely irrelevant.
I know that the rule of thumb is to change fluids, yadda, yadda, yadda, but that isn't always the answer. You need to know what the problem really is before you can decide on a course of action. Simple rules of thumb are sometimes wrong.

there are two ATF fluids in the system. One is the clutch plate bath in the diff... That one needs regular changes as it goes brown and the diff starts making noises.
Second ATF fluid is in the pump and lines going to the diffs. That one is used just to control the pressure plates in the diff... That one doesn't go bad, nor does it get dirty..
Even when pumps corrode, the high pressure part of the pump is still clean and protected from the elements. It is just that the plate between two parts of the pump corrodes so much that the clearances in the pump grow and you get no more pressure.
Second problem is corrosion on the base of the solenoids that causes solenoids to break.
Check the vid in my sig, it is clear....

i don't worry about my fluids because I'm still under warranty so they do my services. but ill deffs leave the pump alone. I'm planning on using some anti corrosive someone told me to use. it had a 15 in the name lol. totally forget. and then plastidipping it coupled with the guard they sell on DSG and a little extra piece of plastic btwn the mudflap and wheel well. best way to go? better options? this is kinda the drift i got when searching the mass threads. the only thing is overheating...
Proven? Not really. Suggested? Yes. Some are in this thread. Others are in the other thread: https://www.evolutionm.net/forums/ev...-pump-pic.html

I'm about to go through my first winter with my Evo - first one I've owned. For those of you that have been through salty roads and whatnot - does having mud flaps help keep some of the crap from accumulating on or near the ACD pump and lines?
Also, do the one or two ACD pump "guard" things that are sold out there do any good? I've seen a plastic cover that sort of seals off the pump from getting hit by dust, sand, salt, debris etc on the road.
