Go in the engine bay and find the in and out coolant lines going to and from the heater core. If you rig up some kind of pressure tester you should be able to see if it's leaking. I'm not sure what kind of pressure they are normally under, but if it's leaking, this method will tell you.

 

Most cooling systems run the 14-16 psi range. You can wait till it starts puking antifreeze into the interior of your car , or you could just suck it up and replace your heater core. I bet our windows fog up like a bitch when you turn the defrost on. Chances are that its your heater core leaking.

 

I had that problem and i had a blow head gasket... but yours is prolly the heater core.... Rockin 200,000k and still havent changed mine... life is good.

 

i think heater cores only ---- up when they are physically damaged. or the ph of the antifreeze is fucked up.. and that causes it to spring a leak.. so as long as u drive ur car right.. and maintain proper ph levels in your antifreeze. it should technically last forever.. my friends fucked up when he accidentally filled hard antifreeze instead of 50/50 and didnt realize it till it was too late...

 

buk your a ------- tool and a 3rd, they can "spring a leak" whenever the goddam pain in the asses go out, and when they do id rather drag my nuts through 20 miles of broken glass instead of ripping the dash apart, thank god a honda isnt as much bs as some others.
