If the control arm bushings on your vehicle are beginning to fail, it will become quickly apparent. Suspension noise will be drastically increased, there will be steering wheel shake when hitting road hazards, and the entire car will have an all around loose feel. This can also lead to premature tire failure as alignment is negatively affected. Replace your control arm bushings to give your entire suspension a tighter feel.

BMW Oil Separator Valve | E38 E39 540i 740i 740iL M62 4.4L Engine is an essential component designed to maintain optimal engine performance by purging oil vapors from the engine block into the valve cover. This valve features four hoses connecting it to the dipstick, valve cover, and air intake system, ensuring efficient crankcase ventilation.

  • Effectively purges oil vapors from the engine block to maintain clean operation
  • Designed for BMW E38 and E39 models with M62 4.4L engine
  • Helps prevent oil separator freezing in cold weather conditions
  • Features four hoses connected to the dipstick, valve cover, and air intake for optimal ventilation
  • Reduces engine sludge buildup, preventing potential damage and maintaining efficiency

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes on a regular basis, it can often crack or break. You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it. This replacement will fit perfectly and provide the same heating and cooling characteristics as an original unit. When replacing, be sure to have some extra coolant. Check ECS Tuning's website for a wide variety of coolants specifically designed for your car. Most German vehicles require specialized coolant. Be sure to pick up the proper coolant when refilling to avoid damage or premature corrosion.
