'04 SRX, V8 N*(LH2), AWD, 85K miles...A couple days ago, my wife tells me that her car is saying "check coolant Level". I go to check it and see a small pool of coolant on the driveway..

It's never a large leak (maybe 5-6" dameter spot).It appears to be leaking from the driver's side, near the firewall...I first thought that it would be an issue with the expansion tank or the hoses but see no issues with those...Any ideas?
