So on my 06 crown vic p71 its got 300 thousand kilometers and it has a headgasket leak but I put that stuff in the coolant and it sealed it up for now and it has a rebuilt tranny. And now it needs a new ac condensor and heater core. It's about 300 in parts and the local shop quoted me 1400 for labor is that worth it or not. I paid 2 grand for it when I bought it
