ok on my 86 GXL my coolent migrates from the cooling system to the overflow bottle and the low coolent light comes on, its pissing me off, im going to diconnect the buzzer today and get yet ANOTHER new radiator cap, but i have also replaced the hose that goes from the rad. cap to the over fill bottle, my senor trouble shoots good, wtf is going on? is there something in the cumbustion area thats blowing air in there? help me out

You might want to have a CO2 test performed on the coolant. If it fails the motor will more than likely need a coolant seal (rebuild time). https://www.nopistons.com/forums/pub...O_DIR#>/11.gif Then again, it could just be a weak spring in a tired radiator cap - which is a lot better problem to have https://www.nopistons.com/forums/pub...1047683329.gif

yep sounds like re build time
