Default Heater Core replacement project

To replace somthing so small.. this is what you have to do...

Drain A/C System
Drain Coolent
Drop Steering Wheel Column
Remove Gauge Cluster
Remove Main wire cluster
Remove Glove Box
Remove all screws from dash that hold it in place
Remove and mark all connections/grounds
Remove Seats/Center Console
Pull Whole Dash backwards
Remove Heatercore housing
Rip apart heater core hosuing it has about 20+ screws on it.
Replace the stupid thing.. and put it all back together.. its pathetic..

Im waiting to go get a A/C Disconnecter tool so i can pull the heater core housing out of the truck then ill be done and have to put it all back together.

here are some pics of the progress...

Did you take pics of the actual steps and where the screws are at and stuff? Has anyone done a DIY on this yet? And for the noob question of the day, what does the heater core actually do?

no i didn't take pics of every step.. you will have to get a Haynes manual or something, the list is outrageously long.

and the heater core gives you heat and defrost.

that is absolutely the most ridiculous thing i have ever seen. For all that work, I would just not have heat. In fact, my 88 blows out lukewarm air and I know it needs a heater core, but im not about to go thru all that.
thats just poor design

if its blowing warm air then that means you have a clogged hose not letting hot water in.

A busted heater core causes lots of Antifreeze to get EVERYWHERE, it was so bad it was pouring out my firewall, i almost over heated.

Thats why im replacing it, cuz if i drive it in the upper rpm like 4500+ it will leak fluid.. so i had to replace it.. and im not paying someone else to do it for 500-1000 dollars.. plus to i needed the experience on how to do this.

Cuz now i can do other peoples trucks and charge them 500$ lol

make sure you check the new heater core and make sure it doesnt leak!!!

I did it my self in the 99, it took a weekend just taking my time. it was a PITA. then I got it all together and it still leaked. I got a faulty heater core. so I said **** it and took it to the dealer. it was only $350 including a new heater core. so there was no way I was goin through all that hell for only $350. so I let them do it and I got a 1 year warranty.

remove the 2 coolant hoses from the thermostat housing, use a garden hose, attach it somehow to one of the hoses, turn the hose on, let the water flow through the system it'll push some crap out, then do it to the other hose to get anything that might've gotten caught, once the water run clear in both directions you can re-attach the hoses and fire it up, should fix your problem

if you look in the 4th picture i took and look for the light green wire thats all by itself on the top of the core housing, right under that metal bracket. Now do you see the shiny part of the black housing kinda looks like a long cylinder?

Right in between the green wire and that black part you can see a small shiny metal piece. There is a wire attached to that and when you turn your heat and cold one way that little wire moves the door open and closed, that little peice could be adjusted wrong, or broken.

I have a 2000 Neon that blows only lightly warmed air. I put a new thermostat in thinking that was the problem but to no avail. Do you really think flushing it might fix my lack of heat problem? It sucks in Utah without heat!

I finished it.

Everything went back together fine, and everything works, no leaks and blows damn good since i cleaned out the vents and crap.

No ratels, or nothing. Im happy. If i had to do it again, i would be able to do it in 8 hours or less. First time is a hoe.

Glad its over with... i didnt take any new pics i just wanted to finish it.. was sick of looking at it.
