Lethal, where is the heater core located and how can it be repaired
Could be a hose that needs a better clamp. DC likes to use them darn crimped clamps (junk). It's located under the hood behind the front tire. It's in that ********* box where your fan etc is. It's very easy to remove the fan assembly. Two screws and two bolts, a couple electrical plugs (watch, one is underneath the fan connected to the fan motor that's kinda hard to see unless you know what you're looking for). I've never had the heater core out, but you should be able to get a bit of a look at it from there. I have to pull mine off this week (installing roller rockers). I'll have a better look for you.
Does it smell like anti freeze? I know my '94 did that and I was scared as h3ll it was headgaskets, but it was the heater core. Didn't smell all the time, just now and then.
