Originally, antifreeze was the preferred term because that was its main purpose. His comment was “I thought all antifreeze was green.”įor our purposes, the titles of Antifreeze and Coolant will be interchangeable, as indeed they are in my business. At the garage, they replaced his coolant bypass hose and the water pump. I contacted a garage in the city where he was vacationing and got him towed. It was empty but there was just enough residue to confirm that what he thought was transmission fluid was actually engine coolant. So it must be the transmission leaking that caused the car to run hot.”Īfter assuring him that a slipping transmission could possibly be the problem, but it was likely something else, I directed him toward the coolant reservoir under the hood. I saw you put it in, and it is the same color, transparent pink.
“The same pink fluid you put in it is now running out on the ground. I asked him how he knew it was the transmission. I questioned him and determined that yes, his engine was running hot. I am on a trip and my car is broken down with an overheating engine” he said, with frustration and anger in his voice. Recently, I got an angry phone call from one of my favorite customers. I can calm, advise, and perhaps solve the automotive challenges over the phone. Always check the specific maintenance and change-out intervals, coolant/antifreeze to water ratio, cooling system capacity, and service instructions recommended for your vehicle.I have always encouraged my customers to call me when they have problems on the road.
