i just put another heater core from another civic and so i put it in there and drove around a bit i found raditor fluid on my carpart. i did clean the raditor fluid when the other core gone bad before i put in the other used heatercore in. and do u guys think the carpet still have some raditior fluid in it when i did vacum it like 6 times all day or it better go buy a new heater core and when my defrost always cold does that mean it has a bad heater core and thermostat?

 

does any 1 know ?
