Well these past two weeks have been all sorts of fun and head banging :banghead with the bronco.

I'm wondering if they are at all related to one another...

Alternator isn't charging the battery *possible bad wiring or bad ground somewhere to screw the circuit up*

and now i have white smoke puffing through my vents in the cab...i pull over...immediately...and no smoke in the engine bay.

:whiteflag


Any correlation between the two? I had the top off and windows down so i really couldn't tell if there was a smell or not.

S.O.S. I ended up making it to work, i only live about 2 miles away. so i took the gamble and drove it there. i might just leave it over night depending on what the census is.

Heater core - pop the glove box out, unbolt the computer or whatever is there and then take out all of the surrounding screws. remove heater hoses from engine bay and remove it - i'm guessing you will have coolant on your pass side floor mat.

I was testing out a new stereo when my heater core popped, I thought I had an electrical fire and freaked out. The bass must have popped a weak spot in the core, lol.

Just ordered the heater core...also ordered a valve cover gasket...just incase.

How easy is it to replace the heater core? esp on the bronco. I've found other write ups on other cars...but none on the bronco.

Do i need to take the whole dash off to get to it?

white smoke from vents... suppose it could be antifreeze, tho would think you would smell it before seeing smoke... another possiblity is leaves & debris getting into the heater core from the cowl... had that happen with my Ranger when I was always parked under a big oak tree... freaked me out when it happened, & took quite a while for the smell to go away. Had to pull the core & clean out the airbox.

No. It's really simple.

Open the glove box, and pop the glove box out of the dash (there are two ears on each side holding it in). The black box behind the glove box holds the heater core. Take the bolts out, remove the cover, unhook the hoses from the other side, and remove the heater core.

If yours is original, it will probably be copper.

Na, just have a good selection of 1/4" drive sockets. (I can't remember the size). Its also been awhile, so I can't tell you if you might run into any headaches.

Also couldn't hurt to top it off with anti-freeze and water again

ok ok ok . . .took me about 30 mins to take all the bolts and screws off....pull the cover off.

I'm looking at the heater core...a few questions arise:
the stock seems a bit bigger than the replacement...does it need to be exact?
How do you pull it out? i was trying and trying and i couldn't pull it out from under the dash. Is there a clip or something i need to release from behind it in the engine bay?


I also took off the blower motor-thought maybe i could have a different access point to the heater core from the engine bay...no such luck...BUT i did clean out a bunch of leaves and gunk in it. :) yay.


Lastly-it seamed that the cover to the heater core had a seal around it...is this needed to be applied back on before i run the truck?

any thoughts?

do i tackle this from the cab and in the engine bay? i just don't know what to do in the engine bay...or how to take it out of the cab...seems nice and tight with very little wiggling room to pull it out. i just don't want to bust anything.
