Is there anyway to replace the heater core OTHER than removing the dash?
What tools are needed?
If I keep the car, I might just try to hack up the dash, so I won't have to go through all the work
thanks

 

No sir. Dash must be removed.

 

i just replaced mine, took like 4 hours, prob do it in 2 now that i know what im doing but you NEED to take off the dash, cluster, drop the steering colum, and steering wheel support, and pry the heater off of the rest of the unit, im not going to lie, its a bitch
ive got pictures if you need them, what kinda civ is it? mines a 93si

 

couple screw drivers, basic socket set, time

And where did you guy's get your heater core.
Can you test a junkyard one to see if it works or is it a gamble and how much does a new one cost.
What are the symptoms of a bad heater core?
I have no heat, can that be one?
I assumed it is.
The only code I have is code 41

They usually leak.

 

forgot about that.
Yeah mine doesn't leak, but it is very bothersome that I have no heat, especially when it gets cold and i need it as a defroster

Hows your coolant level? T-stat working properly? Is the hot water valve opening? How about the heater controls?

 

i don't know what to check on the hot water valve
but t stat and coolant is fine
no leaks

 

Fixed
it was that valve that connects to the heater core.
The valve which should be connected to that wire was loose and it was stuck in the heat position

That was alot easier than replacing a heater core.

 

i mean stuck in the cool position
when the heat is on, it is suppose to be in the same direction the hose is, when the cool is on, it is perpendicular to the hose
