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

Hydrolysis, the breakdown of plastic or rubber by water exposure, weakens the structure over time, leading to failure. To combat these issues, Rein’s upgraded connectors are constructed from high-strength aluminum, eliminating the vulnerabilities of plastic connectors and ensuring long-term durability.

Both thermostat housing hoses to replace your worn out rubber and brittle plastic connections.

Over the years and with exposure to extremely hot coolant, the coolant hoses in your vehicle can take a beating. Being made of reinforced rubber, these hoses can fail in a number of ways. Splitting at a hose clamp, swelling, cracking, and breaking are just a few of the ways this hose can leave you stranded. Replace it at the first sign of wear to keep your coolant in your engine.

Comes with both upper and lower thermostat hoses: 11537830715 Lower + 11537830716 Upper
