Description
BMW's with the N73 V12 engine frequently develop coolant leaks at the front of the engine. Coolant will usually be seen leaking from a weep hole on the front timing cover. The engine has a coolant transfer pipe that runs from the front to the rear of the engine, under the intake manifold, the integrated front seal on the pipe fails causing the leak.
The factory prescribed repair is very time consuming and requires removal of the engine, cylinder heads, oil pan and timing covers. This expandable pipe allows the repair to be done by an experienced technician in under 10 hours, saving thousands in labor costs.
