我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。

We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.
操作说明
本视频介绍如何按照步骤处理 1990 年款 GMC G2500 的轻微冷却液（防冻液）渗漏。 冷却液（防冻液）渗漏是 G2500 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 G2500 发动机内部循环，防止发动机过热。 对于配备 5.7 升发动机的 1990 年款 G2500，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，G2500 的散热器也可能发生渗漏。 本视频展示了您的 1990 G2500 炫速STX车型冷却液储液罐、软管及连接部位的具体位置，并说明了修复轻微渗漏所需的操作步骤。
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 GMC G2500 的温度传感器检测到发动机温度过高。 处理 G2500 的冷却液时，请始终佩戴护目镜和手套。

Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 1990 GMC G2500. Leaking coolant / antifreeze is one of the more common types of leaking fluid from G2500 engines. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your G2500 engine and keeps it from overheating. Coolant / antifreeze can leak from the reservoir, radiator or any hose, in 1990 G2500 with the 5.7 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 G2500 may have a radiator leak. This video shows you where the coolant reservoir, hoses and connections on your 1990 G2500 Rally STX 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 GMC G2500. Always protect yourself with safety glasses and gloves when working with the coolant on your G2500.
