When air finds its way into this closed system, it forms air pockets. How? Many vehicle cooling systems are pressurized and use a sealed hose system that allows coolant flow around the engine. The air causes bubbles in the coolant reservoir. What causes bubbles in the coolant reservoir? While some may not need you to worry, others will require you to take immediate action. Bubbles in a coolant reservoir could suffice for different reasons. However, at a point coolant reservoir may start boiling, and you may wonder why.

This coolant is stored in a rubber tank called the coolant reservoir from here it dispatches coolant to engine components. This system relies on a close network of pipes that carries coolant to the engine. However, most vehicles utilize the liquid cooling system. Animals love its sweet taste, so even a spilling a small amount on your garage floor can end up in the dog's stomach pretty quickly.Automobiles depend on either a liquid or air cooling system to keep the engine running effectively.

These coolants will typically say 50/50 or pre-mixed on the front of the coolant bottle. Some coolants will come premixed-that is, you don't need to add any water.

Mix the coolant / antifreeze with distilled water so that you have a combination of 50% coolant and 50% water. Be sure to check your owners manual to determine the correct type of fluid to add - for Pontiacs, it will typically be in a section titled Fluid Capacities in the back of your manual. The video above shows you where the coolant reservoir in your Grand Prix is located and how to add coolant / antifreeze. Make sure to check your engine when it is cold for an accurate reading. Engine coolant / antifreeze circulates through your engine to keep it cool in the summer but won't freeze in the winter. Adding engine coolant (also known as antifreeze) to your 2007 Pontiac Grand Prix is pretty easy.
