There are many reasons that coolant needs to be checked and changed at regular service intervals. Your cars cooling system has many functions. The main one is of course to remove heat from the engine. A clogged cooling system can cause an overheat that could lead to costly engine repairs or even engine replacement.

Most engine manufacturers require checking the coolant freeze level at least once a year or at each factory recommended service. Another function of antifreeze is actually anti boil as well. Today's modern cars run at a higher temperature than cars in past years. We used to see thermostats open at around 180 degrees. Now to help with reducing automotive emissions coolant is pushed to temperatures around 210 to 220 degrees.

Since water boils at 212 degrees then why is the coolant not boiling? Yes antifreeze/anti boil combined with the pressure of the cooling system raise the boiling point of water to over 300 degrees. Here at Drake Auto located in Sterling, VA we use a tool called a Refractometer to measure you coolants antifreeze and anti boil resistance.
