I've been smelling coolant for a month or so. Times are rough and I've been trying to limp along.

I put some coolant in it a week or two ago. Today on the drive home it overheated. Sitting on the side of the road with my hood open waiting for it to cool down and stop smoke/steam.

I can see some wetness down around the bottom of the engine bay and I don't see anything in the coolant tank.

Safe to assume I'm leaking/loosing coolant? Someone suggested check my oil, it's dark but not milky or foamy.

Oh, and I'm barely (if at all) getting any heat inside the cabin.

What should I check next?

 

Fill it up with more coolant, run the engine, and basiacally look around for leaks, thats the only way to do it. If the engine is cold, feel around with your hands, you should eventually find the leak.

 

Not getting any heat because you don't have any coolant in the system running through the heater core.
I would fill it up too and let it run in your driveway looking for leaks. Could be several things: head gasket is gone, warped head (depending on how long you drove it with the temperature in the red zone), radiator is bad.

 

Check all of the hoses and verify that none are leaking. Also a bad t-stat will cause it to overheat as well as a bad temp sensor.

 

if the t-stat was stuck closed or the fans weren't turning on, he wouldn't be eating coolant.

I am going to go with a leak somewhere or a headgasket starting to go. Both of these are easy-ish to diagnose. Like most said, run it full of coolant and look for where it is spraying out. You could also pressure test the cooling system if you have the tools available to you. For the headgasket you can do a leakdown test, again if you have the tools available to you.
