Post subject: | Heater core replacement - Remove the dash? Really? |
So I have searched and found a few threads both here and other sites about heater core replacement. It seems there is not a definitive method of doing this. Does one really have to remove the whole freakin' dash to get this done? Does anyone have photos of how to do this job? A copy of the FSM showing how this is done? |

We did not remove the dash on my son's 95. It was very tight, but do-able. You will need some hose clamp pliers to get the hoses off, sold at Sears, however I got mine at Autozone. ECM removal seems almost mandatory also, but once you remove 2 screws, unplug the airmix actuator and rod, its free to slide off. Carpet will give you a battle. But the core is easily removed once that cover is out of the way. My hands were not personally involved in the repair, but I watched closely as my son did the job and got up to speed on how much profanity he knew lol. He was sure glad to put the tools up that evening, but its less pain than removing the dash |

I had the hose clamp pliers in the tool box already. Getting the hoses off was easy with the right tools. But I can't even see where to get that box cover out with out removing the dash right now. Anyone has pics of doing this job? |

Digging under here more, it seems given I have the electronic control HVAC (EEC I think you guys call it) that this is complicating things under there. A lot. |

It is not a fun job at all.The cover for the heater core will come out but must be done with the carpet and pad pulled back out of the way.It also helps a lot to remove the passenger seat for more room(not necessary,but makes it easier to work on your back).I do not have any pics,sorry.I know when I did mine it was a battle to figure out the right position for the cover to come out,and go back in,so remember how it came out,wish I would have . I have one with ECC and one without and have done both heater cores, neither was easy or quickly done. It is a great time to flush your system of all the old coolant,since you will be removing most of it anyway. I used this link for some info,maybe you can see some things here that will help.good wrenching. http://trialsnuts.com/ecc.pdf |

Holy Hell! That is about the best I have seen so far! It still looks like a PITA job that I might end up paying someone to do. Can't believe I'm saying that... |

It is. If the one in the 99 ever goes out I will likely sub it out to a shop also lol. I did one in my old 1990, it wasnt nearly as bad. |

After watching my son replace the heater core twice, I think that not having to remove the dash may have a good deal to do with how big you and your hands are and how flexible you are. It is no piece of cake, that's for sure. I have gotten to know the dash well enough to not need help with it until it is time to lift it out of the car - lol. - BC |

Well, I am still waiting for another part to come in before I dig further on this. But right now I have unofficially thrown the "F@#$ It" flag. I'm too old and fat to be lying on my back contorting myself to get this done. I'm going to end up paying someone to do this job I think. |

Yeah I know Madcarpenter. I prefer to do my own work though if possible. This won't be the first or last time this has happened. I know that. |
