Today’s John’s Auto Care post focuses on using the proper fluids for your vehicle. Significant advancements in automotive technology have lead to the development of high-tech fluids to keep modern cars operating at peak performance. This is due to both engineering advances and new high-tech materials used to build family car automotive systems. A simple example of this is the cooling system. For decades it was primarily made out of iron, steel and rubber hoses. There was one kind of coolant that protected these components from corrosion. Now cooling system components are made with various metal alloys and plastics. These materials require different additives to protect them from corrosion. Since the materials used vary among family car auto manufacturers, we now have a number of different kinds of coolant.It’s essential for Lafayette car owners to use the right coolant ... read more

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed. How does it know when to change gears? Today’s automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing, and changes the gears as needed. Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds” are being added. Almost all vehicles have four at least speeds. Five or six is c ... read more

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.

Hello Boulder drivers, let’s talk about batteries. Car batteries are just like any rechargeable battery. They will eventually wear out and die. If you are shopping for a new battery in Boulder, here’s some auto advice to help you. There are two measurements to consider when purchasing a new battery: cold cranking amps and reserve capacity. The power required to start a cold engine is measured in cold cranking amps. The number you need is determined by what kind of vehicle you drive and where you live. In general, higher-cylinder engines require more cold cranking amps than lower-cylinder engines. In other words, an eight-cylinder engine needs more cold cranking amps than a six-cylinder one. Also, diesel engines require more cold cranking amps than gasoline engines. The Eldorado Springs weather also determines the number of cold cranking amps you need. The colder the ... read more
