Stock 2018 with 68k. Mine has been solid and a blast to drive. Finally dealing with the water pump issue, but nothing until now.
Owner reviews for water pump
I love my ‘24 Big Bend. Bought it off the lot with 28 miles and has been my daily driver for 2 years. Racked up 50K miles pretty fast and I get oil changes every 5K. One had one issue and needed my Water Pump replaced after leaking all my coolant and wasn’t getting heat. Was covered under warranty and didn’t have to pay anything.
'22 OBX has treated me well enough aside from the recalls and water pump. A beast in my rural Canadian snow, and feel like a tank on the road.
Fortunately the factory Ford pumps aren't terribly expensive. M-8501-M50A is the Ford racing part number, includes: pump, pulley, bolts.
The pump on my S5 just went out at 50k, almost exactly. $950 for parts and it's actually a pretty simple diy job.
Only have had to do the typical water pump/thermostat (and associated solenoid valves)/motor mounts/lower control arms/oil filter housing gasket.
I used the same kit on my tl and the water pump started leaking 2 years in.
I had a check engine on my SQ7 throwing an under boost code. My brother (a master tech) conferred with a colleague and determined that the water pump was starting to leak and check engine went on because coolant was already finding its way into other components. I wasted no time and just had the work done rather than risk potential bigger issues with turbos etc.
Just had my water pump done on my S4 last week while it was at the dealer for the engine knocking. My Brake pedal was very stiff if the car sat overnight, almost like concrete. The tech found coolant in the vacuum line, the Brake Pedal was losing Vacume and making it extremely stiff after sitting overnight. Turned out my water pump went bad, I never smelled any coolant and did not have any warning lights.
I just replaced the waterpump, thermostat and vacuum system on my B9. Leaked internally into the PCV, I would check the solenoids. Mine has about 68.5k - replaced with the new 6 bolt pump.
