Q: Coolant Reservoir leak ??

asked by on December 10, 2016

So I've been having issues with my coolant leaking and smoke begins to come out my car and it goes from C to H. Thursday I took it to my mechanic bc I wanted to drain the water since it's getting old out. He drained it then put antifreeze in. Now when I had water in there I had no issues with leaking or smoke. So I leave the shop to go to work , 30 minutes later I get to work and 85% of the antifreeze is gone !! I was forced to put some water in it. He did notice my cap wasn't locking as it should when he went to put the cap on the coolant reservoir but how is it that the antifreeze leaked and not the water ??
