Car was leaking coolant over time. Replaced top and bottom rad hoses, and engine coolant temperature sensor. Quite possibly could have gotten away with replacing the o-ring on the sensor and fixed things, but these hoses are getting older. Noticed the car was smoking on the exhaust manifold. Valve cover gaskets failing. Replaced valve cover gaskets, all good now.
