I seem to have an Anti-Freeze leak, although I can't see where. I had been smelling it for a while and suspected it, but today finally looked at the tank and saw it was low. Anybody know of anything I can do to fix this, or if it's a common problem or anything?

 

Do you smell it in the cab? Heater core. Elsewhere? Check the water pump weep hole for a leak.

 

Actually, yes I can smell it inside the cab. So you think it's the heater core then? How expensive does that get?

 

$$$$.
do a search on heater core. there are some posts that report it being very hard, all day job. others that say big, but not that bad. there was a post from 'dodge tech' that said he did them all the time. if you don't want to do it yourself you might try finding a dodge service tech that does side work. i think its about a 5-6 hour job.
