St. Peter drivers rely on their vehicle’s coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it’s cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.

There’s a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that’s easily reached inside your vehicle’s engine, so it can turn to steam which does not conduct heat as well and is harder to contain.

Also, if it’s freezing outside in St. Peter, the water in your engine could freeze while your vehicle is sitting out in the MN cold.

So, if you remember your high school chemistry, you’ll know that a mixture has both a higher boiling point and a lower freezing point than either component alone.

Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in and around St. Peter.

Whenever your vehicle is running, the coolant in the cooling system is working to keep your engine from overheating. When it’s cold outside, the coolant acts as antifreeze to keep the fluid from freezing in your engine.

All that exploding fuel in your engine creates a lot of heat. Without coolant, the metal vehicle engine parts would expand so much that the engine would seize up and stop running. The parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole vehicle’s engine is ruined and has to be junked.

This is why it is critical that St. Peter drivers check coolant levels frequently and have their vehicle’s cooling system inspected for leaks. Also your vehicle has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner’s manual or ask us at Autotronics of St. Peter in St. Peter.

The reason St. Peter drivers need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system’s a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other vehicle cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.

Many St. Peter auto owners ask our advisors at Autotronics of St. Peter why there are different colors of antifreeze. It is very important that you use the correct type of antifreeze. The different types of antifreeze – or coolant – are different colors so you don’t mix them up.

They use different materials to make the cooling system, and they require different types of antifreeze to protect them.

So check with us at Autotronics of St. Peter in St. Peter or your owner’s manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.

If you’re gonna drive around the St. Peter area, you’ve got to be able to see! So having a good set of windshield wipers is extremely important. We’ve all experienced the frustration and fear of not being able to see clearly during a storm or when our windshield is just dirty.

It seems like your wiper blades are always at their worst when you need them the most. But windshield wipers are like most other vehicle parts– they require regular attention in order to work their best.

You really ought to replace your wiper blades twice a year; in the spring and the fall. If it’s going to be a particularly harsh winter in MN, you may even want to get special winter blades in the fall. Winter blades are designed to resist freezing.

Speaking of winter and freezing conditions, if your car has been sitting for a long time and the windshield becomes frozen, don’t use your wipers to clear off snow and ice. That’ll just tear up the blades and cause them to wear out more quickly. It may even damage the wiper motor.

Over time, wiper blades become hard and brittle, and then tear. They also lose their flexibility and just don’t cover the windshield effectively.

Worn wiper blades aren’t just a safety hazard; they can also scratch your windshield. That may require replacing the entire windshield, a big cost for such a little part.

Replace worn blades right away. Our professionals at Autotronics of St. Peter can provide you with a quality replacement blade. They cost about the same as they would at the store, but installation is included at Autotronics of St. Peter in St. Peter.

Of course you also need windshield washer fluid to help your blades do their work. Even though Autotronics of St. Peter will top off the washer fluid with a full service oil change, it is a good idea to have some extra fluid at home, or in the car if you are on a long trip.

Always use windshield washer fluid. Plain water, even that fancy bottled water, may freeze in the fluid reservoir or on the windshield itself, making things worse. Besides, water won’t do a good job of cleaning your windows.

And remember that some vehicles have two reservoirs: one for the windshield and one for the back window, which may be under the hood or somewhere in the back.

So follow these tips to keep your windshield clear and your eye on the road, and give us a call.
