1984 Ford F150 Heater core change?

How long would it take to change this? My dad told me to figure it out.. and im a little clueless. Any help is welcome. THANK YOU!1984 Ford F150 Heater core change?About 1 and a half hour.Book time 20 minutes different between with or without AC.1984 Ford F150 Heater core change?For a seasoned mechanic with all the needed tools... 1-2 hours would be a fair estimation. For the novice... it might take 3-5 simply due to an overall lack of experience. It won't be too tough however, even if you've never done it before. What helps is that there's a lot of room to work under the hood of the truck (assuming that the truck doesn't have air conditioning) and in the cab as well.



Most of the work will be done inside the cab but don't forget that you need to drain coolant from the radiator to the point where it won't flow out of the hoses that carry the coolant from the block to the heater and back. The hoses will be clamped to the heater core itself... the coolant flows through the core and the heater motor blows air through the core, thus providing hot air for the cab. Essentially, the heater core is an exchanger... and it works well for that purpose.



Anyway, what you have to do is expose the heater core and remove it for the new one. There will be a housing that contains the core and the blower... and there will be some ducting and the hoses going to/from %26amp; in/out of it. The housing itself will either have screws or clips holding it together, just take your time when dis-assembling it and don't lose any parts. It will be very simple as I said though... you don't really need a shop manual for this job.



What to make sure of? That you don't damage the new core, the hose clamps are tight (no leaks!), that you don't mix up any air hoses going to or from the housing (they need to be right or you could end up with hot air when the controls are set to cold and vice versa) and that you hook any control cable back up correctly so you can turn on and off the blower motor and adjust where the air goes through the vents. Other than that? Not much to say... but if your dad has plenty of tools, you should be able to pull this off without him. In a few hours. Best wishes!



PS What's a good way to keep track of what goes where? Use a Sharpie ink pen... and mark things before you remove them. I usually use letters like A, B, C. Just mark each two parts that go together with a different letter and you'll be good to go when putting them back together. Woot!
