” Coolant Leak? How to Save Your V12 Without Pulling the Engine

If you own a BMW 760i/760Li (2003 2010) or a Rolls-Royce (2003-2017) with the N73 engine, you’ve likely heard the nightmare: a leaking internal coolant transfer pipe. Traditional shops and dealerships will tell you the only fix is to pull the entire engine a job that can cost upwards of $10,000 in labor alone. 

At Bimmerfix Supply, we believe high-performance owners shouldn’t have to choose between a massive repair bill and a dead engine. Here is how to solve this common “money pit” problem effectively.

1. Identify the Symptoms Early

Don’t wait for the “Engine Overheating” light. Look for these warning signs:

• Small puddles of coolant under the center of the engine.
• The faint, sweet smell of antifreeze after a drive.
• Low coolant warnings that keep reappearing every few weeks.

2. The “Better Way” Solution

Instead of the “engine out” method, the Bimmerfix N73 Coolant Pipe Repair System uses a specialized heavy duty stent and non toxic sealant. It is designed to stop the internal leak where it starts inside the timing cover without disassembling the entire front of your car. 

3. Why This Works (The Benefits)

• Massive Cost Savings: Avoid thousands in unnecessary labor hours.
• Durability: Our system is made from heavy duty materials designed for the high heat environment of a V12 engine.
• DIY Friendly: While any competent mechanic can do this, it is accessible enough for an experienced hobbyist with the right tools.
