It's very important to ensure the battery is unplugged and system drained of electricity for about 30 minutes prior to disconnecting any of the orange or blue connections that go to the SRS (airbag) system. That's honestly the only word of caution I would give for your video. Great video! You do not want any surprises when it comes time to airbags. :P

Thanks for the comments! I always disconnect the battery and in the future will let my viewers know! ;-)

Just wanted to say thank you. Your the first video that I've seen about the heater core on this car. I went half the winter last year with now heat.

[@mymechanicdallas]

I'm glad it helped you! Now you will be warm this coming winter!

Gotta rant.... My first car being a fairlady z at 16 I assumed the designers were doing the best they could to pack it all in a sexy package. Had to pull the engine to replace the turbos. I'm 35 and my daughter bought this vehicle cheap last year as a college freshman. I'm FULLY certain that most design engineers for MANY makes and models are simply self aware sadist satisfying their kink and laughing at the steps required to repair simple things. Lmao my amazement at having to strip the front interior has slowly mutated into hate. I pushed the "every adult should know how to repair the things they own and not fully rely on others" with her or I'd gladly have paid the cost of replacement.
Gahhh!
End rant. Thanks for the video, it's very helpful!

Sometimes a good rant is the best policy! I'll fully understand how you feel! Engineers have a lack of empathy for people like us! By the way what happened to your Fairlady Z ?? That happens to be one of my personal favorites! I would give anything to own one.. I had 7 280Zs at one point!

I have a 1999 Mazda 626 that looks to be about the same as in your video. Regarding replacing the heater core, do I have to do anything to the A/C system? Does the refrigerant have to be evacuated? I have the tools to remove the dash, but am not a mechanic, and don't have the equipment to service the A/C system. Can I assume that the coolant needs to be drained before replacing the heater core?

[@jaysonmason279]

Thanx for the vid. Do you kno if this well apply for millennia.?

[@mymechanicdallas]

I honestly don't know. sorry

[@adriandude85]

Wow... was going to attempt this but had no idea how much of the car I need to take apart. Any idea what the labor is for this fix?

[@mymechanicdallas]
