Re: Thermostats going bad 2 in 7 months?

I had a Dodge Spirit that would fluctuate the temperature gauge. I had a pinhole leak in one of the hoses. Not sure how, but fixing that pinhole leak stopped the fluctuation.

My Integra does the gurgle after shutdown. I know that car has a leak. I have to top it off and I can see dried coolant spray. Pressure drops pretty quickly after shutdown. I should probably fix it, but that car is beater status with 360K miles, so I just top off the coolant every month.

Makes me wonder if my 1/8" bleed hole is hiding a swing that I would have without it.

Really, as long as it isn't loosing coolant, can build and maintain pressure, isn't overheating or boiling over, I'd call it good enough.
