How hard is it to install a new heater core? I drive an 89 crx dx...so i believe it's located somewhere behind the glovebox or in the dash...if neone has any advice or ideas..holla at me

 

You sure it's bad it's kinda of a pain

 

true...i am pretty sure its the heater core...b/c the radiator hoses are warming up, water is getting to the heater core, and the fans are working...my a/c works, but no heat...i cant think of anythign else that could be broken

 

its probably clogged

and if you have to replace it all you have to do is rip out the ENTIRE ------- DASH to get to it....
should only take....

a weekend + some

I still need to fix mine because the end tank on it blew; dunno how but it was gushing coolant one day

 

i would just hook up a hose(water hose) to one of the lines comming off from the heater core (that are right on the firewall). then turn that sucker on and see if any water comes out the other end. its a good way to check to see if its clogged or not.

i have done a heater care ounce on a like 86 civic. it suckes bigtime

 

^^^ definatly do what crx2fast says.. Just unhook both lines going to the heatercore and blast that ---- with the garden hose both ways to see if you cang et some flow. Otherwise the dash has to come out. And if you have AC its even a bigger pain in the *** because you have to discharge the AC system.

 

thanks for the advice...i will try what you guys said, and hopefully it will work

 

also, on one of those heater hoses that go into the firewall below the fuel filter has a little valve and a cable, make sure that cable is attached and that the Hot/Cold **** in the car moves it.

This valve allows coolant into the heater core, if its stuck closed you get no heat.

 

i bypassed my heater core.. it was leaking water adn i never fixed it...no heat for me...oh well. I dont want to take out the whole dash for that. I juts use heavy coats when its cold

 

i hooked up the water hose...and the heater core wasnt clogged ...however, after filling up the radiator with water/anti-freeze...me and dustin noticed white liquid being flushed up...wtf? I guess it's time to break out the power inverter and my electric heater
