Congratulations on joining the esteemed ranks of 1995 Mercedes Benz S600 V12 owners! As a fellow enthusiast and mechanic specializing in these magnificent machines, I understand the blend of excitement and perhaps a touch of apprehension that comes with owning a classic V12 W140. Let me assure you, with the right approach to maintenance, your 1995 S600 can be remarkably reliable and provide years of driving pleasure. In fact, many seasoned Mercedes aficionados, myself included, often prefer the pre-1996 models like yours for their robust engineering.
To keep your 1995 Mercedes Benz S600 V12 in peak condition, proactive maintenance is paramount. Let’s delve into some key areas that deserve your attention. A common issue in W140s, particularly those slightly newer, can be the top engine wiring harness. While your 1995 model is less prone, preventative replacement is a wise investment. Sourcing a quality harness is crucial, and options range from reputable online suppliers to dealerships.
The hydraulic suspension system, while offering a luxurious ride, is known to be one of the more costly systems to maintain on the S600. Overhauling the shocks and springs can be a significant expense. A practical and cost-effective alternative for many owners is to bypass the self-leveling system (SLS) and install conventional Bilstein shocks. This modification, along with appropriately sized rear spring shims to maintain vehicle level, offers a substantial saving and improved reliability for many.
Regarding the cooling system, preventative maintenance can save you from potential headaches down the road. Consider replacing the serpentine belt, fan clutch, radiator, thermostat, and water pump. For those comfortable with DIY car maintenance, this is a manageable task. Otherwise, a trusted independent Mercedes mechanic with experience in M120 engines is your best ally. Furthermore, exploring electric fan upgrades, such as SPAL fans, can offer enhanced cooling efficiency and potentially lower engine temperatures, beneficial for the longevity of your V12.
Finally, when it comes to fluids, adhering to specific recommendations is key. Mobil 1 oil, specifically 0W40, is the gold standard for these engines, and consistent oil changes are crucial. Many dedicated owners opt for more frequent intervals than factory recommendations, sometimes as often as every 3,000 miles or even less under demanding use. Fuel quality also matters; using premium Shell gasoline, ideally filled during cooler temperatures and off-peak times, is a practice favored by meticulous owners for optimal performance and fuel system health.
Welcome to the world of the 1995 Mercedes Benz S600 V12. Embrace the journey, prioritize preventative maintenance, and you’ll be rewarded with the exceptional experience this iconic vehicle offers.
