Procedure notes
Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 2009 Cadillac DTS. Leaking coolant / antifreeze is one of the more common types of leaking fluid from DTS engines. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your DTS engine and keeps it from overheating. Coolant / antifreeze can leak from the reservoir, radiator or any hose, in 2009 DTS with the 4.6 liter engine. However, a coolant leak (aka an antifreeze leak) is most likely to occur where the hoses connect to the engine or radiator. Otherwise, your DTS may have a radiator leak. This video shows you where the coolant reservoir, hoses and connections on your 2009 DTS L are located and the steps needed to fix minor leaks.
A few things to note about coolant is that it is sweet tasting and highly toxic, so it can end up in the dog's stomach pretty quickly. If you ignore a small coolant leak long enough, you will run out of coolant, which leads to an overheated engine and other serious, but highly avoidable, problems. An anti-freeze leak can cause the temp sensor to record high engine temperatures in a 2009 Cadillac DTS. Always protect yourself with safety glasses and gloves when working with the coolant on your DTS.

本视频介绍如何按照步骤处理 2009 年款 凯迪拉克 DTS 的轻微冷却液（防冻液）渗漏。 冷却液（防冻液）渗漏是 DTS 发动机比较常见的液体渗漏问题之一。 发动机冷却液也称防冻液，在 DTS 发动机内部循环，防止发动机过热。 对于配备 4.6 升发动机的 2009 年款 DTS，冷却液（防冻液）可能从储液罐、散热器或任何一根软管处泄漏。 不过，冷却液（防冻液）最容易在软管与发动机或散热器的连接处发生渗漏。 此外，DTS 的散热器也可能发生渗漏。 本视频展示 2009 年款 DTS L 的冷却液储液罐、软管及连接处的位置，并介绍处理轻微渗漏所需的步骤。
请注意，冷却液带有甜味且毒性很强，犬只可能很快误食。 如果长期忽视少量冷却液渗漏，冷却液最终可能耗尽，造成发动机过热和其他本可避免的严重问题。 防冻液泄漏可能使 2009 年款 凯迪拉克 DTS 的温度传感器检测到发动机温度过高。 处理 DTS 的冷却液时，请始终佩戴护目镜和手套。
