how can i tell if it is a heater core or water pump that is causing the car to overheat. new t-stat and rad. no leaks on ground or cab. does not have heat in cab and only one heater hose is hot

 

hey i have a 94 intrepid i had it since 1994, i know everything about this car lol and im a mechanic, your problem is you have a clog heater core. and by the way intrepids are funny in the summer, they attend to overheat under extream heat wave so to resolve that problem take the ts out and leave it out it cools the motor better trust me i know, and make sure there is no air in your cooling system, you have to bleed them.
