The OE plastic connector is a frequent failure point due to brittleness and cracking caused by repeated thermal cycling and hydrolysis. 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.

The Coolant Outlet Connector connects the engine block coolant outlet to the upper radiator hose.

Due to fragile plastic construction and consistent exposure to hot, chemical-rich engine coolant, this piece is prone to degradation and (potentially) complete failure.

Whether you're fixing a failed connector or preemptively replacing this failure-prone component, choose this quality replacement from Bremmen Parts for a lasting repair.

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the front side of the engine. Additionally, the two o-rings that seal this hose to the cylinder head and the water pump housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating.

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.

This coolant pipe connects to the thermostat module. When replacing the thermostat module, aka the heat management module, or other nearby cooling components, such as the water pump, this coolant pipe should be replaced. The o-ring seal also tends to flatten over time, preventing a proper seal after reinstallation, leading to a coolant leak.

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the left side of the engine. Additionally, the two o-rings that seal this hose to the water pump flange and the thermostat module housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating. This is especially helpful due to its cramped location, requiring the intake manifold to be removed for replacement.
