Procedure notes
Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 1990 Ford E-150 Econoline. Leaking coolant / antifreeze is one of the more common types of leaking fluid from E-150 Econoline engines. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your E-150 Econoline engine and keeps it from overheating. Coolant / antifreeze can leak from the reservoir, radiator or any hose, in 1990 E-150 Econoline with the 5.0 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 E-150 Econoline may have a radiator leak. This video shows you where the coolant reservoir, hoses and connections on your 1990 E-150 Econoline Custom 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 1990 Ford E-150 Econoline. Always protect yourself with safety glasses and gloves when working with the coolant on your E-150 Econoline.

本视频介绍如何按照步骤处理 1990 年款 福特 E-150 Econoline 的轻微冷却液（防冻液）渗漏。 冷却液（防冻液）渗漏是 E-150 Econoline 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 E-150 Econoline 发动机内部循环，防止发动机过热。 对于配备 5.0 升发动机的 1990 年款 E-150 Econoline，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，E-150 Econoline 的散热器也可能发生渗漏。 本视频展示 1990 年款 E-150 Econoline Custom 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 1990 年款 福特 E-150 Econoline 的温度传感器检测到发动机温度过高。 处理 E-150 Econoline 的冷却液时，请始终佩戴护目镜和手套。
