where coolant?
 

Our 2012 Eco boost has 135k miles, has given us minimal issues with the exception of loosing coolant. It started about 6 months ago when I noticed the heater was not working. After checking/adding coolant she was as good as new (or so I thought). Recently i have been adding coolant every couple of weeks or about 600-800 miles but does not leak on the ground ever. After a ride on the highway I can smell burning coolant in the engine compartment, but no leakage?

Weird, yes.

Anybody else with the same issues?

thanks

I've heard of a few leaking around the coolant lines to the turbos. There's 4 lines going to each turbo, an oil in and out and coolant in and out. Check these out.
