My Subaru wagon is so temperature sensitive that I could probably use it as a thermometer. At 80 degrees F, or so, it starts with very little hesitation. Any lower than that, and it takes a while to turn over, and there are clunking sounds. Lower temperatures mean increased clunking and a longer start time. I’ve always managed to get it going so far, and I live in a place that’s very hot in the summer months, so I’m fine for now, but come September, I’ve got a problem.
I’ve had it looked at by two local mechanics and they confess to being stumped- battery tests fine, starter seems good, fuel additive didn’t make any difference- anyone have any other suggestions?
