good evening everyone,
i have a 97 z28 and everytime i drive it for more than 20 minutes then park the coolant/water comes out of the coolant boilover tank, i keep filling it up with water, but after driving it 3-4 times i need to fill it up again. it doesnt over heat, the worst that will happen is my "low coolant level" sensor turns on and i just fill it up again also when the coolant gets to low, but not low enough to trigger the sensor, the engine temp goes up 3/4 of the way before the thermostat kicks in and cools it down.. anyways, where should i start?

Could be your thermostat is stuck closed or your radiator cap is bad.

thermostat was changed recently.. can the rad. cap impact the system that way?

yeah pretty sure take a look at this thread: https://www.camaroz28.com/forums/sho...d+radiator+cap

If the cap is not holding pressure, it's going to blow by into the remote reservoir.

how funny.. such a simple fix. I took the old cap off after driving it and NO pressure was released! thank god it wasnt something expensive.. thanks for all of the quick replies
