CAR LEAKING ANTIFREEZE

1995 Mazda Miata • Manual • 87,000 miles

Why is my 1995 mazda miata leaking antifreeze from two small hoses that connect together in between another hose? Do I just need to replace the clamps? They are both leaking out from around the clamps. The hoses are fine

The thermostat housing attaches to the front of the head and is sealed by a rubber o-ring. My experience is that if the antifreeze leak is at the front of the engine it is either this o-ring needing replaced or one of the small by-pass coolant lines has developed a leak. I also replace the factory hose clamps with new screw type hose clamps as these secure better than the factory clamps. If the leak is on the driver side of the engine the heater core supply and return hose could be at fault.
