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.

学习如何冲洗您的 2000 GMC Savana 1500 的冷却液（防冻液） 冷却液/防冻液流经 Savana 1500 的散热器和发动机，以维持适当的温度。 冷却液/防冻液也会流经位于车头罩内的暖风水箱，为您的Savana 1500车厢提供热量。 除了防止车辆过热外，冷却液/防冻液还能润滑水泵和软管中的密封件。 开始冷却液冲洗作业，首先将储液罐内的冷却液/防冻液排出，然后打开放液阀或拆下下 radiator 管道，排出散热器内的冷却液。 本视频展示了 2000 GMC Savana 1500 车型散热器放液阀（放液阀）的位置。 向散热器中加入蒸馏水，并启动发动机。 关闭发动机，排出水，向散热器内加入防冻液，直至形成 50/50 冷却液/蒸馏水混合液，并排出冷却系统内的空气。
就像你的Savana 1500里的机油一样，冷却液随着时间推移会变脏，失去冷却4.3升发动机的能力。 当你对你的 2000 进行冷却液冲洗（即防冻液冲洗）时，会将所有的旧的脏冷却液排出，从而避免将来出现昂贵的散热器和冷却系统维修费用。 上述视频展示了您的散热器上放液阀的位置，如何冲洗冷却液/防冻液，以及如何排出冷却系统内的空气，以确保您的 Savana 1500 正常运行。
冷却液有毒，动物会被冷却液（防冻液）的甜味吸引。 当你冲洗Savana 1500的冷却系统并更换冷却液时，如果洒出冷却液，务必铺上猫砂吸收，以便清理。 定期冲洗冷却系统并更换冷却液，可以清除发动机中的污垢和矿物质沉积，并延长暖风水箱、节温器、软管和水泵的使用寿命。

Learn how to flush the coolant (antifreeze) in your 2000 GMC Savana 1500. Coolant / antifreeze circulates through Savana 1500 radiator and engine to maintain the proper temperature. Coolant / antifreeze also passes through the heater core under your cowl to provide heat to the cabin of your Savana 1500. In addition to preventing your car from overheating, coolant / antifreeze also helps lubricate the seals in the water pump and hoses. Start your coolant flush by draining the coolant / antifreeze that is in your reservoir, then drain the coolant that is in your radiator by opening the petcock or removing the lower radiator hose. This video shows where the radiator drain plug (petcock) is located on a 2000 GMC Savana 1500. Fill up the radiator with distilled water and run the engine. Turn off the engine and drain the water, fill up the radiator with antifreeze until you have a 50/50 coolant / distilled water mixture and burp the system.
Like the oil in your Savana 1500, coolant gets dirty over time and loses its ability to cool down your 4.3 liter engine. When you flush your coolant, which is antifreeze, on your 2000, you are draining out all of the old dirty coolant and preventing costly radiator and cooling system repair down the road. The video above shows you where the petcock on your radiator is located, how to flush the coolant / antifreeze and how to burp the system to get the air out of your Savana 1500.
Coolant is toxic and animals are attracted to the sweet taste of coolant (antifreeze). If you spill coolant when you flush your Savana 1500, be sure to put down cat litter to soak it up to discard it. Flushing the coolant on a regular basis removes gunk and mineral deposits from your engine, while prolonging the life of your heater core, thermostat, hoses and water pump.
