Cooling system pipe burst

[Anyello76]

2002 745 Li 105.000 miles.

(short version) Parked the car in the garage, as soon a the garage finished closing, I hear what sounds like water hitting the ground. I take a look under the car, and right before my eyes. I see ALL of my coolant leak out in a matter of seconds. No trail in the driveway, it didnt starl to leak until I shut the engine off (go figure).

(Fast forward to today). Got it towed to the DEALERSHIP. Thinking the worst thing it might be is the waterpump. Then I get the dreaded call. The cooling system pipe burst. 709$ in parts. 41 hours of labor for a grand total of 4.604$. OUCH!!!!!!!. I was told the engine pretty much has to be taken out in order to gain access to the area.

I am in the Charlotte area, PLEASE HELP.

Even if the whole engine had to be removed, it shouldn't take a qualified BMW mechanic 41 hours to do the job!
I think you have been ripped off. Ask to see the part(s) which had to be replaced, then come back to the forum with a bit more detail - I would be amazed if it was anything which necessitated 41 hours labour to fix!!!!

That is a 2002 E65 745, ever seen inside the engine room?
Not that easy as on an E32.

Just to give you an idea, the warranty time from BMW is 28.5 hours, this is what the dealer techs get paid for warranty work, Mitchell gives a time of 27.5 hours. I could see them adding some time to make a big job like that worth it them to do out of warranty, but an extra 12.5 seems crazy, especially when they know its coming out of your pocket, and at $95 per hour (Charlotte, right?, Winston-Salem labor is $125)
I am making this same repair right now without taking the engine out. It is a bit tricky because the engineers decided it was a good idea to make the o-ring for the problem coolant pipe as part of the pipe that gets sandwiched inbetween the lower timing cover and the block.
Have you had yours fixed yet?

Hello,


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!
