I found out the bottom right bolt on my thermostat was stripped.
I did a timesert and went about my day.
5-6 months later I notice a small leak coming from that same bolt.
Ive read forums of people only using 3 bolts to hold thermostat and they’ve been fine.
Does anyone know how I should go about this issue ?
Do I take out the time sert and add a new one ?
Do I change the gasket and thermostat one more time ?
