06 dodge caravan

for  going on a year when I drive, the front of the vehicle smells “hot” , the coolant is draining out very slowly, over a few months to get below the minimum line.. there is no coolant on the garage floor. I have taken it to two different mechanics, one said the hose needed tightened but both can find nothing else. the gauge never goes to over heat I want to take it to another mechanic but don’t know what to tell them…I am a widow and know little about cars but do know my car and its ailments, thank you
