BMW 745i Coolant Tube Failure
We repair it with All German Auto’s replacement tube
BMW has a costly and not uncommon problem with the coolant transfer tube in the middle of the engine on its late model V8 engines. The initial complaint is usually loss of coolant leaking from a small weep hole at the front of the engine on the timing cover. This is commonly mis-diagnosed as a water pump problem. The vehicle may also have coolant leaking from the back of the motor at the intake manifold valley area.

The replacement of the failed tube or tube seals can cost between $9000 - $12,000 at some dealers. This job requires removal of the front timing cover, cylinder heads, intake manifold, timing chain and timing chain vanos systems and many other components. This requires 60 to 80 hours labor!
