So recently i was driving my rx7 home from work and my engine started to overheat so i pulled over and discovered that one of the radiator hoses busted. So the next day i fixed it and thought all would be good so i started the car and i noticed the engine started to shake real bad and was making really weird sounds so i shut it off and looked a little more. Upon looking i discovered that there is no circulation of my coolant i dont no what to do besides take it to my mechanic but has anyone heard of anything like this cuz im lost i dont kno the most about cars and i really wanna kno wut i've gotten myself into
