    The oil cooler/heat exchanger for the automatic transmission is one of the most overlooked sections of the 540i and 740i cooling system. The cooler (heat exchanger) is a part of the overall cooling system and uses coolant circulated from the regular cooling system to cool the transmission oil running through this small cooling block. Some of the hoses are shared with the rest of the cooling system as well. The E38/E39 heat exchanger is located along the driver's side frame rail and is accessed from the wheel well. We recommend servicing or cleaning the heat exchanger along with any cooling system overhaul. Or if you're having transmission faults (especially for temperature) you may want to clean the transmission cooler anyway and these hoses will be a nice finishing touch.

    Replacing or cleaning the heat exchanger components could lead to better shifting of the automatic as the cooler itself can become clogged. If you're experiencing harder or hesitating shifts, and the internal transmission temperature is rising without being regulated, the components in this system are the likely cause. Staying on top of the cooling needs of the transmission will help prevent a very costly transmission repair in the future. These hoses are easily replaced and you can clean the heat exchanger easily with brake cleaner and some brushes.

    Included in this handy package are:
  • 11531711381 - transmission cooling hose from water pump to radiator (with t-connector)
  • 11531711385 - transmission cooling hose from radiator to cooler
  • 11531711384 - transmission cooling hose from cooler to water pump
  • 11537511207 - transmission cooling hose from cooler to chassis
  • hose clamp
  • o-ring


    This hose set fits the following BMWs:
    1999-2003 E39 BMW 540i
    1999-2001 E38 BMW 740i 740il

    Positioned directly in the charge pipe's path, the stock B58TU upper cylinder head cooling hose, primarily made of plastic, is prone to damage. A dislodged charge pipe can easily take out this cooling hose, leading to severe engine damage through rapid coolant loss and overheating.

    To address this vulnerability, VTT has engineered a robust solution. By replacing the OEM rubber hose with a durable 7-ply silicone variant, they offer superior resilience and longevity. Furthermore, they've upgraded the factory plastic flanges to 6061-T6 billet aluminum with black anodizing, enhancing corrosion resistance.

    This upgraded hose is the ultimate solution, providing protection against dislodged charge pipes and the heat generated from spirited driving or track use.

    Key Features:

    Direct factory replacement for easy installation 6061-T6 billet aluminum with black anodizing for improved corrosion resistance Durable 7-ply silicone available in three colors Upgrade your BMW B58TU engine with this enhanced cooling hose from Vargas Turbo Technologies for superior performance and reliability.

    Heat is the enemy of power, and the last thing you want is hot coolant heating your charge air even further right before it enters the charge cooler, but this is what BMW has done on the S58. This is done for emissions and quick warm-up purposes. However, If you are looking to make power on the S58, and are upgrading your charge cooler, or adding PI. While you are there, it takes 30 seconds to remove the coolant lines from the TB connections and replace them with our billet coolant delete kit. This completely removes the coolant from the Throttle body and provides a bypass for the coolant. Simply remove the two lines going to the throttle body, and run our hose in their place. You leave the coolant fittings on the TB open and avoid any unwanted heat being introduced into your charge tract. In our opinion a must for full effort builds. We take the work out of it for you. Kit included: One Plug and Play TB Coolant Delete Hose Kit Features: Billet 6061 Anodized coolant fittings for long leak-free life Reinforced 7-ply silicone hose for strength and longevity Vibration-resistant crimp clamps 100% plug and play, NO cutting or removing factory clamps or hoses.
