Anyone that drives a car in Kalispell knows that engines get hot when they run. But did you know that engines need to be cooled to keep running? Heat inside an engine can cause the metal parts to expand, which can seize up an engine and make it stop running. It can even ruin the entire engine! Good car care requires keeping your Subaru cooling system in good condition.

A vehicle’s cooling system circulates water and antifreeze (coolant) through the engine where it absorbs heat. It then flows to the radiator where the water and antifreeze are cooled by the air that flows over the radiator. Then it circulates back into the Subaru’s engine to absorb more heat.

Why shouldn't Columbia Falls car owners just use water? Because water boils at temperatures that are often reached inside of an engine. Steam won't cool your Subaru engine and is hard to contain within the cooling system. The antifreeze keeps the water from boiling.

So why do we call it antifreeze? Shouldn't it be antiboil? Truth is, the antifreeze performs another critical task. Water freezes in cold MT weather. That would spell disaster for your Subaru's engine. So antifreeze also keeps the water in your cooling system from freezing in all but the most extreme cold. Pretty neat stuff!

Taking care of your cooling system is part of good preventive maintenance for your Subaru. Kalispell drivers should check coolant level often and regularly inspect your cooling system for leaks.

That is just good auto advice. Your Subaru’s manufacturer has maintenance requirements for draining and replacing engine coolant. Consult your owner's manual or ask your professional and courteous Loren's Auto Repair tech for these recommendations, as they vary widely from among auto makers.

Changing your coolant is also part of good preventive maintenance. Water is great at collecting all kinds of dissolved substances, especially when it's hot. Water circulating through an engine picks up dirt, debris, pollutants, and other stuff. It actually becomes corrosive over time. This can damage engine parts and your radiator.

Replacing your coolant regularly keeps the Subaru cooling system functioning well and doesn't allow it to sneakily become the cancer that wipes out your engine.

But don't just slop any antifreeze into your vehicle. Check your owner's manual or ask your Loren's Auto Repair service professional if you don't know what is the right type of antifreeze for your vehicle. Using the wrong kind can void the warranty on your Subaru cooling system.

You may have noticed that different types of antifreeze are different colors. Manufacturers tint them different colors to make them harder to mix up. It's easy to notice that you have purple fluid when you normally use green! That way, you have less chance of damaging your Subaru engine by using the wrong antifreeze.

One last word of warning — a little outside the area of car care. Never, ever let anyone or pets drink coolant/antifreeze – it is deathly poisonous.

Take care of your car, and take care of yourself! Just some good car care tips from Loren's Auto Repair to keep you on the road and help your life in Kalispell run more pleasantly.
