Hi to all. New Acadia owner. Fell into a 2009 SLT-1 with "Wait for it" 27,198 certified miles. It looks and drives like new. Have only had it 2 months but it seems to be doing great. I have serviced the tranny with Amsoil synthetic (38 year Amsoil dealer) and just finished replacing the A/C blend door actuator yesterday when the passenger side started to blow hot instead of cold. This is not a good thing in SE AZ. Wanted to know any pitfalls to be aware of. My next 2 projects are 1. to service the cooling system and I have seen some indicators of air blockages causing overheats. Any suggestions there? 2. Install hitch and wiring for towing my utility trailer. I will also be installing a tranny cooler. I have read that these Acadias have problems with the plastic tanks cracking and ruining the transmission by mixing ATF and antifreeze. Any opinions on this? All comments gratefully accepted.
