The Front Seal on the BMW N62 V8 Coolant Transfer Pipe can fail in as little as 40,000 miles. The repair on this internal engine seal requires many hours of labor and can cost thousands of dollars. Coolant is now leaking from a hole in the engine of your BMW, and we are here to help.
The BimmerFix Stent stops the leaking seals.
The BimmerFix Stent stops the leak in your engine by creating a metal inner lining inside the Front Seal of the Coolant Transfer Pipe. The Stent is easy to install through a hole in the Timing Chain Cover, and is made of aluminum alloys which is similar to the alloys used by BMW to match the expansion and contraction of the engine as it heats and cools during normal operation.
BimmerFix Beats The Competition
A leaking Front Seal on a Coolant Transfer Pipe of the BMW V-8 N62 engine is a common problem that is very expensive to repair.
The N62 V8 is a popular BMW engine that was used from 2001 to 2010, in such fabulous vehicles as the 735i & 735Li ( E65 & E66 ) 740i & 740Li ( E65 & E66), 745i & 745Li ( E65 & E66 ), 750i & 750Li ( E65 & E66 ), 645Ci & 650i ( E63 & E64 ) , 540i ( E60 & E60 ), 540i 545i & 550i ( E60 & E61 ), and the X5 ( E53 & E70 ) SUV.
When BMW originally built the N62 engine the Coolant Transfer Pipe (part # 11 14 1 439 975) was installed through the front of the engine block before the installation of the Timing Chain Cover. Once the engine is installed in the vehicle it is very expensive to remove the Timing Chain Cover in order to install a new factory made BMW Coolant Transfer Pipe through the front of the engine.
A second method was later developed which involves accessing the Coolant Transfer Pipe by removing the Intake Manifold. Once the Intake Manifold has been removed, then the old Coolant Transfer Pipe can be cut-out of the inside of the engine block and a new “COLLAPSIBLE COOLANT TRANSFER PIPE” is installed in it’s place.
There are several companies who manufacture these Collapsible Coolant Transfer Pipes. This is the most commonly used method of repairing a leaking Coolant Transfer Pipe because it is cheaper and faster to remove the Intake Manifold than the original factory method of removing the Timing Chain Cover. The problem with both of these methods is that the Front Seal on both the factory installed Coolant Transfer Pipe and the after-market “Collapsible Transfer Pipe” could eventually LEAK AT THE SAME PLACE AGAIN in the future.
The BimmerFix Stent offers a MORE DURABLE METHOD of repairing a leaking Front Seal on a Coolant Transfer Pipe at lower cost. The seal created by the BimmerFix Stent is more durable because it is made of high-strength aluminum alloy similar to the BMW engine. The BimmerFix Stent actually provides a METAL LINER and bonds to the Coolant Transfer and Timing Chain Cover using the special high-temp BimmerFix Coolant Pipe silicon sealant. This BimmerFix Sealant is able to be continuously immersed in antifreeze, and can withstand temperatures up to 500 degrees Celsius. The labor to install the BimmerFix Stent is approximately one hour more shop time than is required to replace the Water Pump. In fact, we recommend that a new Water Pump be installed when installing the BimmerFix Stent, or that a BimmerFix Stent is installed in a vehicle when the Water Pump is being replaced. This is an inexpensive measure which could help to prevent future failure of the Front Seal of the Coolant Transfer Pipe.

BimmerFix Cooling System
Sealer & Conditioner
The BimmerFix Cooling System Sealer & Conditioner IS NOT REQUIRED to stop the “weep hole” leak from the Front Seal on the N62 Coolant Transfer Pipe.
The Front Seal leak is repaired by the BimmerFix Stent. However, The BimmerFix Cooling System Seal & Conditioner is designed to condition and seals (#4) of the Coolant Transfer Pipe (#3), Valley Pan and Gasket (#1), as well as the gaskets of the rear Coolant Passage Cover (#5).
The rear Coolant Passage Cover Gasket (#5) is very expensive to replace because it requires the removal of the transmission and the rear exhaust system.
