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

Has your BMW's with the N62 V8 engine developed a coolant leak at the front of the engine from the timing cover weep hole? If so the it is likely that the coolant transfer pipe seal, located below the intake manifold has developed a leak. Normally, replacing the seal on this pipe would require almost 40 hours of labor and involve removing the entire engine from the car, then removing the cylinder heads, and timing covers. With this new collapsible pipe this repair can be accomplished in under 10 hours! This solution will save you or your mechanic from a bunch of headaches and get your V8 back on the road leak free!

With more than 100 years in the industry, Elring is one of the oldest names in the European autoparts segment. Delivering OE-quality you can rest assured the job will be done right the first time.
