after we flush the old coolant... and put the new coolant in.... we drove it and the check engine light went on... and what we did was try to reset the car by the battery and still went on... just wondering what would be the cause why the engine light goes on???? the car is a 2000 integra..... with basic bolt ons.... hope u guys can help out... thanks....

 

What trouble code does it have stored? Did you bleed the air out of the system?
