Quote: A word to the wise, i was given by a member here. With anything close to a stock charging system , the HHR fan will flat eat up a battery in a mighty short time. A guy told me he had a 50 amp denso on his car and with that fan, ran out of juice on a sortie on the street one night because of how much juice that HHR eats. That is the only reason i dont currently have one, and just bought a much lower amP draw new fan for my car....aa i have a stock alt, not even as good as his Denso that didnt cut the mustard. Your results may vary
I don't have a stock alt, but I am going to measure the draw tonight when I get off work. if I remember correctly it drew way less power than most previous fans I have had. Also, since the swap I have noticed zero difference in battery charging or anything electrical related. as mentioned though, like everything on here, your results may vary.
