Well today I parked my car and I saw smoke coming from the hood. So I popped it and saw coolant all over the place. It's coming from the back of the motor but I can't see what it is or what it could be. I drive a 90 integra. Any help would be great

 

Probably a old, hardend, cracked, rubber coolant line squirting fluid onto your cat.

Wait till the car cools down and carefully inspect all coolant hoses behind your motor. Replace all hoses that are hardend and old.
