have a 96ss, it starts to overheat if i let it sit for 15min. both fans kick on, first the pass fan then the driver fan. and coolant start coming out of the res. not sure what sensor to swap out? thanks for any help. after it overheats there is air in the cooling system.

Check your coolant cap - this is a replacement item - is it 14 years old? Have you had a pressure test done?

+1 Sounds like a bad cap, the coolant should not boil until the needle is pegged in the red.
