Acquired a 1997 Subaru Legacy a few weeks ago.
Drive it for a prolonged time in the heat, at speed, and you can smell warm coolant from the engine compartment. And the temperature gauge hovers in the middle of the dial, no matter what.
My wife explained the smell away by guessing she’d spilled coolant when she topped it up. But it’s been weeks since she did that.
Also - this sucker drinks coolant. I’m guessing every 2-3 days I’m adding another gallon.
It occurs to me that … maybe … a leak on top of a pipe so the coolant doesn’t drip out, but the loss of pressure (from the hole) causes the fluid to boil and flash out?
This might explain the ‘higher than I’d like to see’ operating temperature.
What say y’all?
