About GM Cooling Hose
In the cooling system, there is an important part named cooling hose or may say radiator hose, and it is designed to stop the engine from overheating. When your GM is running, the cooling hose carries coolant through the radiator and engine to keep it working in a reasonable temperature. There are two cooling hoses in the system, and they are located in the upper and lower connecting to two radiators respectively. Here are some signs demonstrating your cooling hose is failing: if the A/C or heater doesn't work well; if the coolant is leaking; if the steam comes out of the engine compartment; if there are bulges or cracks in cooling hose, you need to buy a brand new one to replace, or it does damage to your engine. We offer GM genuine OEM cooling hose with a discounted price.
