Apparently I am now an official member of the ACD – AYC failure group. I guess I should count myself is one of the lucky ones I have 90,000 miles on the original unit, how ever after putting in a new transmission apparently the pump would not start after sitting for six months waiting for the transmission to be shipped and installed. Is it really just the electric motor that fails in these units I would not think the whole unit would need to be replaced. This seems to be an expensive problem. perhaps there is a simple solution. Does anyone know what the number one failure is of these units I am mechanically inclined I'm going to attempt to remove the motor and to see if there is anything obvious that an oil and clean job will not take care of.

Also does anybody know if here in America does anyone offer the relocation kit for these pumps. There is a website I found in England that actually allows relocation into the trunk.

Primary reason for pump failure is corrosion causing the pump to be unable to make pressure.

Motor failure is more rare but happens in older units.

Update

I just removed the unit from the vehicle it is confirmed the actual electrical motor is bad everything else looks perfect. Is there anyway of getting or repairing just the electrical motor portion of this unit is only three bolts I know failure of the motor is rare and it seems difficult to get apart.

 

Yes, you can purchase only the motor, I believe also from the site I posted.
How to get it apart... you watch the video I posted and you'll find out.

**Edit: btw, if you go as far as taking the motor off, you might as well buy the whole rebuild kit. Eventually it would just fail again due to corrosion. The replacement parts contained in the rebuild kit are far superior to what's on the pump from factory.

 

Between replacing the motor, and doing the rebuild kit you're better off just buying a new pump at that point. Pretty sure you can find them at dealerships for a little over $1,000. You can sell your current ACD pump for parts to recoup some of your money. In the end you'll probably end up spending close to the same amount.

 

I don't think its 1000 usd for the pump in the us. I am from Michigan and three dealerships considtsntly told me it's 1800 bucks. Just the pump. Another 250 for the install and pump bleeding/ programming. Only consolation , the pump comes with 12000 miles/ 1 year warranty.

About the reasons for failure, my pump failed on the polar vortex day(-38). It lasted 70500 miles of good Midwest winter driving. I believe the extreme temperature cause the fluid viscosity to go pretty high and the motor was unable to pump it.

 

Around $1400 is the lowest you'll find for a new pump.
