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 in 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009 and 2010, in such fabulous vehicles as the BMW 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 at the factory, 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. However, once the engine is installed in the vehicle, it is very expensive to remove the Timing Chain Cover, in order to be able 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, that is also much less expensive to install. The seal created by the BimmerFix Stent is more durable because it is made of high-strength aluminum alloy that is made of a similar alloy as 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 usually only 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. And, vise-versa, we recommend that a BimmerFix Stent is installed in a vehicle when the Water Pump is being replaced. This is an inexpensive preventative measure which could help to prevent future failure of the Front Seal of the Coolant Transfer Pipe.
