I was under the car and taking off the bolts that hold the ACD pump onto the base, greasing the bolts just because. since i was under there i thought of putting my plan into action.

held by the OEM screw upfront and OEM push clip on the back.

 

this is for evo's in the colder climate correct? to prevent acd pump failure? or is it to prevent freeway debris from hitting the ayc?

 

Similar question I have yet received an answer. Cold or not I don't think I've heard of a ACD pump going bad without corrosion to the pump itself. So my question is relatively close to yours, but I want to know IF storing the vehicle during winter snow seasons would help prevent this issue. Or people that live in the areas where it doesn't snow and salt isn't used on roads.

 

Both my son and I have 2011 GSR's. My son has 23k miles and has driven his Evo in the winter. Mine has 5k miles and is stored in the winter. My pump housing looks almost like new. Yes, not driving it in the winter does make a difference. Or, get the ACD kit and put your worries behind you.

 

Supposedly the main thing that causes the pump to fail is in the winter, the fluid gets very thick from the cold. A pump that keeps trying to pump highly viscous fluid will fail faster.

Another option is to disconnect your AYC pump for the winter

 

Its not just the cold, its all the salts and other debris that corrodes the pump and seals.

 

Love how this was done. What kind of plastic was used?

 

I just got a new AYC this summer and I want to protect it this winter (northern Idaho), is there a kit out there to help shield the pump like OP has made?

 

i wish this was around when i had my X, i got rid of it due to this ACD pump problem. Deffinately getting this if i get another one

 

Did you get rid of it preemptively or did your pump actually go out?
