We are still working to obtain content for your car, however the video above is believed to have similar characteristics as your car. Adding engine coolant (also known as antifreeze) to your 2007 Mercedes-Benz ML350 is pretty easy. Engine coolant circulates through your engine to keep it cool in the summer but won't freeze in the winter. Make sure to check your engine when it is cold for an accurate reading. The video above shows you where the coolant reservoir in your ML350 is located and how to add coolant. Be sure to check your owners manual to determine the correct type of fluid to add - for Mercedes-Benzs, it will typically be in a section titled Fluid Capacities in the back of your manual. Mix the coolant with distilled water so that you have a combination of 50% coolant and 50% water. Some coolants will come premixed-that is, you don't need to add any water.

These coolants will typically say 50/50 or pre-mixed on the front of the coolant bottle. Removing the coolant reservoir cap on a warm engine could cause the cap to fly off at a high rate of speed and fluid to spray out of the reservoir. Always wear safety goggles when working on your ML350. Promptly wipe up any spilled fluid as it is highly toxic. Animals love its sweet taste, so even a spilling a small amount on your garage floor can end up in the dog's stomach pretty quickly. Change the parking light Small bulbs that burn out regularly - did you know you can replace these with LED lights? Replace your wiper blades Did you know that the sun wears out wiper blades faster than rain? Add air to your tires Properly inflated tires is the easiest way to improve fuel economy.

Even so, The Environmental Protection Agency estimates that the six-cylinder will return 17 mpg city, 22 mpg highway and 19 mpg combined. For 2012, the city fuel economy has been increased by 13 percent. We spent our time behind the wheel of the ML350 BlueTec 4Matic, which is powered by Benz's 3.0-liter turbodiesel V6 engine with 240 horsepower and 455 pound-feet of torque. The company's engineers have worked to diminish harsh vibrations generated by the diesel cycle. As a result, the engine features an internal balance shaft snugged between the cylinder banks. The piece counter-rotates at the same speed as the crankshaft and is driven by a double chain that operates the twin cams in each cylinder head. Additionally, the connecting rod journals are offset by 30 degrees to promote a smoother-running engine. It all translates into one of the creamiest, quietest diesel engines that we've ever had our hands on. We routinely found ourselves purposefully hunting for the familiar rumble and knock of the diesel engine from inside the cabin and coming up empty.

All M-Class models come equipped with a revised seven-speed automatic transmission that's seven-percent more efficient than the outgoing gearbox. Part of that efficiency comes from utilizing a special blue fluid with a lower viscosity, which in turn allows for lower hydraulic pressure. The transmission also features a lock-up torque converter that can lock in at any gear. New programming also allows the gearbox to skip up to four gears at a time to put the engine at the correct speed at the right time. The company's 4Matic all-wheel-drive system remains standard as well. In addition to the new transmission, the ML350 is also available with Parktronic active parking assist thanks to a newly revised electro-mechanical power steering system. And while we typically wince at word that an automaker has abandoned traditional hydraulic power steering for electronic wizardry, this system handles itself well at a variety of speeds. Check out our Short Cut below for a look at how the active parking assist performs. Mercedes-Benz also significantly revised the suspension on the 2012 M-Class by offering the optional Dynamic Handling Package.
