Differential Essential (Differential Fluid Exchange)

What's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels.  The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn).   Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there.  (Your vehicle may have more than one differential in it depending on the drivetrain.)  As you can imagine, it's important that the lubricant in those differentials do its job.  Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down. So, it's important to have the differential fluid exchanged every so often.  Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km ... read more

Idle Talk about Engines (Causes of Rough Engine Idling)

When you slow down at stoplight, your vehicle's idle should be smooth as silk.  But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key." You can help your service facility if you can describe the problem in detail.  Here's a list of things to make a note of: When is the problem happening, when the engine is cold or when it's been running for a while? Does the rough idling occur when I'm accelerating or when I'm going at a steady speed? Does it happen at high speeds?  Does it happen low speeds? Does it happen at both? Make sure you describe the problem in as much detail because it will help a technician diagnose the problem. One of the first things they'll check is how the spark plugs are firing.  Modern iridium plugs are supposed to last a long, long time.  But they CAN even ... read more
