I'm curious about this. Where have you seen them leak? I understand it can be difficult as you say, but it has to leave evidence somewhere? I ask because I had some unexplained loss of coolant in my overflow, but no evidence of any leak... other than some crustiness at the overflow cap. some reading led me to believe that I might have topped off my overflow too much and through expansion, overflowed from the reservoir cap. I started to suspect a HG issue since I have a V6 (but an '08, where the VAST majority of HG issues were in the earlier 4th gens, specifically the '04's). No evidence of leaks that I could find anywhere else. I've since done my 150k flush and no loss of overflow. So I'm curious when I hear of issues pertaining to current goings on with my vehicle. Not trying to call you out or anything, just want to hear more if you have any more..
OP, count me among the "leave it alone if it's ok" crowd... If you keep to your flushes, then you ought to be fine.
