Was changing my heater hoses and must have yanked too hard on one of the hoses going to the heater core. Yep you guessed it, the heater core now leaks. I need the car on Tuesday to take my son to his school formal, so I need to bypass the core. Problem is, one hose is 3/4" and the other 5/8". Does anyone know where you can get a connector with different sizes? Is there another way around this as a temporary fix?
