Last night on my way home my truck started making a rattle noise. Once I got on to the high way the rattle stopped but as I reached 40mph it started popping and didn't wanna go any faster limped it home and popped the hood on the left side (passenger) of the motor there's a wooshing sound today I got under the truck and there's a green liquid water droplets on eveurging but my antifreeze is orange so I'm all kinds of confused any one ever have this problem?

I've asked around some people say could be Cadillac converter plugged and another person said map sensor
