Today's Tuffy Tire & Auto Service Plainfield post focuses on using coolant. 
If you pour in the wrong kind, it won't protect the cooling system and may even void the warranty. Check your vehicle owner's manual. Of course, your Tuffy Tire & Auto Service Plainfield service advisor will know the proper coolant for your vehicle.
Brake fluid is confusing for some Plainfield drivers. Back when we opened Tuffy Tire & Auto Service Plainfield, most vehicles used Dot 3 brake fluid. Now we have Dot 4 and Dot 5. Some Plainfield residents mistakenly think the higher numbers are an upgrade. You know, if 3 is good then 4 must be better. That's not how it works. They are different formulations to meet the demands of differences in brake systems. Only one of them is designed for your vehicle.
Ditto for transmission fluid. For decades there were two basic types of tranny fluid used at Tuffy Tire & Auto Service Plainfield: friction modified or not. With the tremendous engineering advances in vehicle automatic transmissions, there have been several new types of fluids developed to protect and lubricate them.
Nowhere are the advances in automotive fluids more evident to Tuffy Tire & Auto Service Plainfield professionals than in motor oil. Many new weights and formulations have been created to meet the demands of today's high-tech vehicle engine design. Modern engines have more parts and much tighter tolerances.
That's where the new grades of engine oil come in. They have to be formulated to lubricate, protect and clean all of those vehicle engine parts, big and little. The oil has to be thin enough to get into little passages, yet resistant to vaporization.
At Tuffy Tire & Auto Service Plainfield in Plainfield, we believe that in some ways modern automotive fluids are just as impressive as the new engines. Because weights of oil and types of coolant and transmission fluid are so carefully matched to the vehicle, make sure you always use the proper fluid if you are topping off at home.

Many of us have become aware of how important it is to keep our planets air clean, and your vehicle has a key component that helps do just that: the catalytic converter.

Your vehicle's brakes wear out. It's inevitable. You'll notice it when you step on the brake pedal and feel it harder to stop, or there's vibration when you are braking. Most modern vehicles have disc brakes that each use a brake pad that press on a disc (disc brakes!) called a rotor. The fric... More

If you have a vehicle with an automatic transmission, you probably never think about gear shifting. When motor vehicles were invented, all of them had to be shifted manually. But that wonderful self-shifting transmission, referred to these days as simply an automatic, changed everything. Automa... More
