Video Description

The video above shows to check the coolant hoses in your 2000 GMC C3500. The coolant hoses (radiator hoses) carry engine coolant through your engine and will eventually wear out. You can avoid getting stranded by identifying signs of extreme wear before they break. In 2000 C3500s with the 7.4 liter engine, coolant leaks are most likely to occur where the hoses connect to the engine, but it can also leak from the reservoir or from the hoses. Look for cracks in the hoses and analyze the brittleness or squishiness of the hoses in your C3500 - if the hoses are hard to squeeze or squeeze very easily, it's time to replace them. The video above shows you where coolant hoses on your 2000 C3500 Sierra SL are located and the steps needed to analyze them.

Never attempt to replace a hose that is connected to your air conditioner - these hoses contain refrigerant that is under pressure and can blind you. AC problems are always best left to your professional mechanic.
