Dreaded N62 (4.8i)Coolant Leak - Merry Christmas

[cgrosse]

But look the aftermarket responded and came up with a collapsible repair pipe to cut the bill down to around $1500.... THAT WORKS! Get hooked up with a quality reasonable independant BMW repairer and spending money to have a E70 4.8i is WORTH IT

I am writing to tell you about a new BREAKTHROUGH method for repairing a leaking Coolant Transfer Pipe in the BMW N62 V8 engine block using the BimmerFix Stint. The N62 V8 is a popular BMW engine that was used from 2002 thru 2010, in such fabulous vehicles as the BMW 735i, 740i, 745i, 750i & Li, 645Ci, 650i, 540i, 545i, 550i, and the X5 SUV.


Located deep inside of this BMW N62 engine is a Coolant Transfer Pipe, which carries antifreeze from the Water Pump to cooling chambers within the engine. However, the Front Seal on this Cooling Tube can fail in as little as 40,000 miles, and start leaking antifreeze from the engine block, through a weep hole in the Timing Chain Cover. When this happens, the car will lose antifreeze from the engine, and the engine will overheat.


In the past, this has been a very expensive repair because it required disassembly of the engine, in order to access the leaking Cooling Pipe Seal. The original method of replacing the crossover Coolant Transfer Pipe required the removal of the Timing Chain Cover. This repair could cost $6,000 or more at the BMW Dealer.


Then, an after-market Collapsible Coolant Pipe was developed to save time and money on this repair. This Collapsible Coolant Pipe method involves removing the Intake Manifold, cutting out the old Coolant Pipe and installing the after-market Collapsible Coolant Pipe. But even this method required many hours of shop labor and expensive parts and supplies. The repair bill for this method can still cost between $1,500.00 and $2,500.00 to remove the Intake Manifold, cut out the old Coolant Pipe and install the new Collapsible Coolant Pipe.


However, BimmerFix Products Co. has discovered a BREAKTHROUGH system to stop the leak! The BimmerFix method is much faster and less expensive than these old methods. This simple, yet durable and long lasting method inserts the BimmerFix Stint into the leaking crossover cooling tube, through the Timing Chain Cover. The thin aluminum sleeve creates a long lasting repair that is much easier and less expensive to install than the old repair methods.


The new BimmerFix Stint will stop the Coolant Pipe leak, and only requires the removal of the Water Pump. This new patent protected invention can save YOU or your customer’s time, hassle, and thousands of dollars. It works or your money back!

BMW is cutting edge... not a Toyoto appliance. Yup you gotta spend money to fix the things that break but to me BMW whole experience is worth it. Sure $10K to fix a coolant leak is CRAZY...

Sorry, to drag up an old thread but I get so sick of reading this misinformed marketing crap. BMW is a car manufacturer. They make cars with the same heating, cooling, lubrication, all the systems you need to make a car work.

They are not magic or "cutting edge" in most of their applications. They just make VERY poor design choices and use inferior materials in many applications. They have a history of systemic failures of components and systems (transmissions in the X3, door handles on many models, sunroofs across all pano models, etc). They do not do a good job with their engineering and manufacturing for long term reliability.

I hate to burst your bubble, but you're just repeating what a salesperson or brochure is telling you. Grab some tools and start disassembling, and you will quickly find all the same components that make that Chevy run too.

^^ Interesting product.

Wonder how long IT lasts....given the heat cycles that part sees, I'd be concerned with the middle o-ring as it is the sole source of the preload onto the two other seals. Plus there is a split in that shim that jams the front washer into place....

At ~$500 they are making a killing....

My 2008 4.8i is now a member of this club, and I would have preferred to not join...
She's in the shop having a Valley Leak repaired right on time at 69k miles... $3400.
To make it even better, the Thrust Bushings were cracking, so they are also being replaced... $750.

It's a big hit, no doubt, but I can't piture driving anyting else.
Just love this car way to much...

what are the symptoms to the infamous valley coolant leak? Does it leak internally or run down the motor and on to the ground?

[95wildtt]

I had a low coolant warning when starting up for the first time one morning, and again a couple of days later. Took it to my Indie (in Indy) shop to have them top it off. It was 1/2 Gallon low, and the noticed a very small amount of coolant running down the back side of the block.

There was never a puddle or drip under the car, no smell, nothing that pointed to this. The leak is very slow and gets burned off by the heat from the block and headers/exhaust before getting to the bottom of the car to drip...

A system pressure check confirmed it. Now I'm without my X for up to 2 weeks.

Ok. Thanks for the heads up. This vehicle scares me lol! Too many potential repairs coming up...
