2017 BMW 328 GT with a coolant leak that had been chased for months. Two big repairs. An oil filter housing replaced. A water pump replaced. And still — coolant was disappearing.
When it landed in our bay at Howdy Automotive, we did what we always do: slow down and actually diagnose the problem.
We pressure tested the cooling system, traced every drop, and followed the evidence — not assumptions. What we found was something most shops overlook entirely.
The water pump sits on an accessories bracket that bolts directly to the engine block. Between that bracket and the block lives a small seal. A seal that ages, hardens, and fails quietly — mimicking a water pump leak so convincingly that even a brand new pump won’t fix it.
That was the culprit.
We replaced the seal, and even found an oil leak starting, reassembled everything properly, and sent this BMW down the road coolant-tight for the first time in months. One happy customer. One solved mystery. 🙌
If your BMW has a coolant leak that keeps coming back no matter what’s been replaced — don’t throw more parts at it. Get it properly diagnosed.
