My truck had major leaks when I first bought it, I have done crank seal water pump seal Tstat and housing. Checked all hoses. I still smell burning coolant and have to top off a quart or 2 every other day. I have no signs of a blown head. I know there's got to be a tricky unseen hose or something I'm not seeing? Not Mich dripping so I think its above exhaust and burning

Thanks!

 

I recently had a leak with similar symptoms. It ended up being one of my heater hoses was leaking and dissipating pretty quickly so it was tricky to track it down. I wasn't getting any dripping on the ground either. I would definitely check those.
