So my girlfriend has a 04 Honda Civic lx and the Heater core is leaking already confirmed this as I took the dash and everything out and there was a puddle of coolant underneath. I think I removed all the bolts but still can’t remove the housing. Disconnected the hoses discharges the ac and any obvious bolts around the housing does anyone know how to remove this??

 

U-TOOB has many videos on a variety of car repairs

 

Is there a mounting nut on the engine bay side for the heater unit that you missed?
