The video above shows to fix minor leaks in the coolant hoses in your 2007 Chevrolet Express 3500. The hoses carry engine coolant (which is also known as antifreeze or anti-freeze) through your engine and will eventually wear out. You can avoid getting stranded by identifying signs of extreme wear before they break and fixing minor leaks promptly. In 2007 Express 3500s with the 6.0 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. In addition to looking for cracks, analyze the brittleness or squishiness of the hoses in your Express 3500 - 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 and coolant reservoir on your 2007 Express 3500 LS are located and the steps needed to first minor leaks.
