Removing heater core.

My heater core to a crap on me in TX but now im up here in Mass and its getting cold so I need to replace the heater core. I have looked into this a little and it looked like I had to remove the entire dash. Is this true or is it like a hour job to do? any suggestions or pictures would be great.

This one has pictures right on!

But I heard that alot of the times it could just be the hoses, I mean how would the heater core get a hole in the first place?? thats my questions.

Thanks Richmond

They corrode and rust out! Remember that coolant which is an acid is running through that thing all the time.

I just did that a few weeks ago. Not a bad job. Only problem for me was putting the screws back through the firewall. It was a PITA to get those lined up.!!! But now I have some HEAT!

Take the dash off nothing.
It's 4 nuts from off the firewall, a few clamps, an electrical plug, a snap clamp, and a handful of screws.
Shouldn't take long at all, it's a one man (2 beer) job.

I did mine not too long ago, It takes about an hour and half. if you remove the passenger seat it gives you way more room to get in those awkward positions

My heater core went bad about two years ago. I fought the idea of replacing the heater core. I thought it would a PITA to replace.
On my YJ it's four nuts that hold the heater box / mixing box. The hard part for me was disconnection the cable from there brackets.
Other than that it came right. There is a good writeup here on how to. The other thing I found was to make sure the hoses fit and are tight.
