Hi all, new to the forum. I read through all of the heating threads, didn't see what I needed. Picked up an 01 XLT 5.4 a couple of months ago. Local mechanic sold it to me and it is in excellent condition. Just this week I'm getting the wonderful coolant odor in the cabin. No obvious leaks. Nothing dripping in the garage, no standing fluid on the engine that I can see, and no smell under the hood. Getting steam on the windows of course. Not overheating, no loss of fluid (or extremely slow loss). Blows good heat. Just gotta find the source of the odor. I suspect heater core, but would like to hear from others. Could it be heater hoses? Thanks for any ideas. I can do a lot of work myself, but know when to get pro help.
