FORD CROWN VICTORIA ENGINE COOLING

Hi, I Have A 1990 Crown Victoria Wagon-181000 Miles. Whenever I Drive Quite A Bit, Upon Stopping At A Light I Hear A Banging Noise...

My P71 Is Leaking A Mininum Amount Of Antifreeze From The Bottom Of The Drivers Side, I Can't Seem To Find Where The Leak Has Originated...

I Put Coolant In My Car, And It Leaked But I Can't See Where It’s Leaking It's Not Under The Car But I Put Coolant In There Again...
