New here. Just got a 2001 986 S with 142 on the clock

I'm a little confused by the pictures. When you opened the cap, did you then see all the gunk? It looks as though there is no coolant in the tank at all? Or, had it been drained? IF there is no coolant in the tank, or hasn't been, that seems very odd. Sometimes, a cap can get white/brownish gunk as you see from condensation. Notorious in my Jeep, totally harmless, just means I need to drive it harder. Not sure if the Boxster has this issue potentially or not. I agree with the rest, no matter what route you take, you need to flush the snot out of your coolant system, until the entire system runs completely clear, then test from there.

Yeah, pic was taken after the test drive and coolant leaked right out the overflow tube under the engine. I tried to post a video but for some reason it says it needs a moderator approval.

That is applicable to the oil fill cap, not the coolant
