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. NOTE: BMW's updated 2-way design requires the additional purchase of 17127598004 (Radiator Hose Cap) to block off the Y-connector in the expansion tank vent hose, or the expansion tank vent hose can also be replaced with 17127536235 to eliminate the Y-Connector entirely!

Rein OE Quality Transfer Case Control Motors are made to factory specifications ensuring proper fit, form, and function and come complete with mounting hardware. A transfer case is a vital component of today's highly complex AWD drivetrain systems, and the failure of its components such as the transfer case motor, clutches, and bearings is a definite reality. Its job is to constantly synchronize the difference between the rotation of the front and rear axles. Problems arise when this difference in front to rear rotation slips outside of predetermined parameters due to uneven front to rear tire wear, for instance. This excessive difference forces the motor and the clutches to engage more frequently leading to their accelerated wear. This also leads to a quicker breakdown of the transfer case fluid due to additional heat. Therefore, Rein highly recommends its FLDF002 OE transfer case fluid when replacing the transfer case motor. Rein transfer case motor actuators offer a convenient solution for this common repair! Ensures the proper operation of the vehicle's AWD system Engineered and manufactured by an OE manufacturer Plug and play replacement for original transfer case motor unit. Comes complete with mounting bolts

The A/C condenser cools down hot refrigerant, much like a radiator. If the condenser is broken or bent, then the refrigerant will either leak, or inefficient airflow will not cool the refrigerant. If you've damaged your condenser or if you suspect any blocked flow or leaks, replace it. This will ensure your cooling system is operating at peak efficiency.
