Rear Engine Radiator lines/ Heater core? need help! Ok Wasup guys. im new to the site and also new to honda's. I bought a 92 Hatch CX and I need to know what the small Holes in the rear of the motor for the antifreeze go to. they had no lines on them. I bought the car after the guy did a 16v swap cause he blew his other one. he didnt finish the whole swap. so i bought it not moving. so does anyone know where these lines go to there are 3 i believe.
