Okay picked up this civic sedan riced out. But anyways I'm a mechanic and have messed with Honda acuras for years. I know I can replace the heater core but I need other options on getting it unclogged.
-Tryed the hose pipe (but could not get a good connection)
Just seeing if you guys have any ideas of something I could pour down there?
Long story short I replace the headgasket and the previous owner put stop leak in there I know that what stopped it up.
Any ideas?

thats like getting a curb rash and saying f it im getting a new rim... have you ever replaced a heatercore its not fun at all took me 2 hours to do it by myself and rushing it

unplug both the hoses from the heater core best way to do it is not to do it from the core itself but from the motor run some garden hose water into the heatercore into the OPPOSITE direction that it flows so the hose closes to the passanger side.. than put compressed air into it and have something that catches it like a milk jug than run a little bit of CLR trough the core and keep running water until all the CLR is out of the system but remember do all this the opposite way the core flows

at the end just do a couple more runs with a garden hose into the heater core but the way the core actually flows just to make sure u got everyhting out

replaced mine last week when my engine was out...

yeah it's a pain. but if i get a new part on my 200K + mileage car, i wont worry about it later.

Just what i'm used to doing.

Yeah I know its a pain,and yes I have replaced it more times than I can count. Right now this is my only car. Me being a mechanic I'm busy with other cars,I will try the methods y'all have listed. I'm just doing this temporary till I start my build thread with this car. Ill go ahead and say I have done so many diffrent swaps I think I'm staying with a d series on this car.
