Ok, I have had my Legacy LS for about 2 years. The milage is about 101K. This is what happens when it seems to overheat.
It does it intermittantly, but there is loss of coolant at times. Sometimes not at all. Normally the temp guage sits just under half. When it does over heat, I do not let it get past 3/4 on the guage. Tonight, while driving, it was fine going up hill, and normal driving at a slower speed. When I started to accelerate, up to about 40-45, the guage started creeping up. I was very close to home so I just drove it, as normal, slowing down. When I entered my apartment complex, the speed limit is 5-10 mph. When I slowed down, the guage and temp started going down to normal. By the time I parked, it was where it normally is. I popped the hood and there was no steam, but I did not check the fluid levels since it was dark and I couldnt see well.
It does this like every few months, moreso when it is cold out. When it is hot outside, I do not have this problem normally. I am hoping this is a thermostat problem or a radiator problem rather than a gasket problem.
Anyone have any ideas?
Thanks!
