Hello all

[dschallmo98expo]

on my 98 expo, I have to completely remove the dash to get to heater core. Fixing to do mine next month, as I purchased it second hand with 165K miles on it and I just got done refurbishing the interior and do not want to damage the trim, carpet, or headliner or seats. Proactive.

I can handle a heater core. At least that's the cheaper route

See what happens when u step on it !Just kiddin with ya. Pressurize it to be sure. Probably is the core, but check other spots to be sure. Under hood and all fittings and hoses.

Just from driving it today to work (10 miles) the sweet smell was almost unbearable. I'll have to do it this weekend

You can bypass the heater core if you still need to drive

Sorry, wasn't done, run a hose from water pump to block bypassing heater core , right fellas. Remember I'm old school. Don't want to give him any bad info!

I installed the 9011 HIR's I bought the other day. They're noticeably brighter. Put the old 9005's in the fogs for now until I order another set.

I work night shift so I'll hopefully get to look at the hoses before work today if I don't sleep too long. Looks like heater core (and/or hoses) and the hub will be next on the agenda. Still have to fix the electrical gremlins before the snow comes

Just recently bought a 1998 Expedition 4WD. Heater kicked on when I went to run the AC and smelled coolant. Rear AC works great. From my researching it sounds like it's the heater core. Yea. Well since I'm in Austin (Buda) I don't need the heater much so I'm looking at bypassing the heater core at least until next winter, those 2 weeks in December.

I've watched a few youtube videos on bypassing the heater core. Looks easy enough for a non-mechanic!

By the way, this is my first post and I'm looking forward to learning more about my 98 Expy here. I also came across this forum while searching "matte black paint Expedition" and saw a really nice $250 DIY in a member's driveway. Looks great!
