Video Description

Follow the steps in this video to see how to fix minor coolant (antifreeze) leaks in your 2000 GMC C3500. Leaking coolant is one of the more common types of fluid leaks on C3500s. Engine coolant (which is also called antifreeze or anti-freeze) moves through the inside of your C3500's engine and keeps it from overheating. Coolant can leak from the reservoir or from the hoses, in 2000 C3500s with the 7.4 liter engine, coolant leaks are most likely to occur where the hoses connect to the engine. The video above shows you where the coolant reservoir, hoses and connections on your 2000 C3500 Sierra SL 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. In many 2000 C3500s, an anti-freeze leak can cause the temp sensor to record high engine temperatures. Always protect yourself with safety glasses and gloves when working with the coolant on your C3500.
