Hi everyone I'm asking this question for my 19 yr old brother who has 96 t-bird with a 4.6 v8 the motor was rebuilt almost a year ago due to two of the cylinders were geeting coolant in them and ever since then the car seems never to have coolant in it when he checks it he is allways on top of checking it out but it has not been resolved if anybody has a idea what it could be I would appreciate it thank you.
