FAQs—Mercedes Benz 450SE
Recently, I am experiencing engine hesitation whenever I try to accelerate my Mercedes Benz 450E. It buckles up and jerks. What are the common causes of this kind of problem and how can it be fixed?
This indicates that something might be wrong in your vehicle's internal combustion. In general, engine hesitation points out that there might not be enough fuel going to the vital parts of the engine. The engine may be sucking too much oxygen, causing the vehicle to buckle and jerk. This is especially evident every time you try to accelerate, brake or drive downhill. Engine hesitation can be a very frustrating issue. The first thing you have to do is to check the fuel pump. How is the quality of the fuel? Does the pump have any holes or cracks that might cause leaking? Is the fuel clear and clean or grimy with bits of debris? These circumstances may affect fuel flow and be the root cause of the problem. Also check the oil filters. Inspect for signs or corrosion or damage then replace if necessary. If it is not a fuel issue, perhaps there is something wrong with the transmission. Check if there is sufficient transmission fluid in the pump. Check if the quality of the fluid is in good condition, otherwise you would also need to flush it out. Check the clutch and determine if it needs to be replaced or adjusted.
How come the tires of my Mercedes Benz 450E wear out so quickly? What can I do to make it last longer?
Keep in mind that the Mercedez Benz 450SE is not designed for off-road and rough terrain driving. Therefore, do not exceed what the vehicle is designed for to save the tires from undue stress. Evaluate your driving habits as well. Perhaps you brake too harshly or you forget to drive at steady pace. All these can hasten to quick tire wear. At least once every month, check the pressure of your tire. It would even be better if you can check the pressure at least once a week. Do not forget to include the tires every time you wash your car. Wash from top to bottom to avoid spreading the tire dirt to other parts. Wax the tires as well. Explore tire sealants and protectants as many of them are available in the market. They would add extra protection to the tires.
The coolant fluid of my Mercedes Benz 450E is creating a puddle underneath the car. What parts should I take a look at?
There are a number of reasons why the coolant fluid, or "antifreeze," is leaking. It is always best to take your car to an expert mechanic regarding this matter. However, some of these things are the most common causes of antifreeze leaks. The radiator cap might already be damaged and corroded. It may also be suffering from weak pressure. If you have a weak coolant cap, the antifreeze fluid may overflow from the tube every time there is increase in heat and pressure. If you have the skill and know-how, then you can do a DIY pressure test in your garage. Also, inspect if the radiator has a hole or a broken hose. The water pump might also be already leaking. Check the head, block, internal gasket and other parts of the cooling system.
