Mechanic Works On Lincoln. Then He Notices Major Design Issue: 'This Is What Comes Out Of Your Motor'

A diagnosis of a bad water pump doesn’t seem like a major under-hood surgery job for most vehicles. But the mechanic wants viewers to know that for certain vehicles, it’s a very different story, and a messy one involving fluids that look borderline revolting.

The clip from creator Foreign Finesse (@foreiginfinesseimports), which has more than 159,000 views, has images that call to mind an automotive horror show underneath a Lincoln MKZ where the motor has been removed to access the water pump that needs to be replaced. And under the machinery is a basin filled with the brown sludge that results from coolant mixing with motor oil.

“When your water pump goes out, you gotta drop the whole motor from the car, but this is also what you're filling your motor with,” the mechanic warns while using his hand to stir up the contents that look like the bottom of a murky lake.

Ford Fans, Detractors Face Off

The mechanic doesn't identify the specific engine in the video, but the warning will sound familiar to many Ford and Lincoln owners. (Ford is Lincoln's parent company.)

Certain versions of Ford's 3.5-liter and 3.7-liter V-6 engines use an internally mounted water pump that's inaccessible without considerable time- and labor-intensive disassembly work.

Rather than being mounted externally as in most engine setups, the Ford engine has the water pump buried behind timing components. In some cases, a failed pump can also allow coolant to leak into the engine oil, creating the thick brown mixture shown in the video and potentially causing severe engine damage if the problem isn't addressed quickly.

The mechanic's warning resonated with viewers. But instead of focusing entirely on the repair, many of them used the video as an excuse to argue about the Lincoln MKZ itself.

"I don't think ANYBODY wants a Lincoln MKZ buddy," one commenter wrote.

The jab quickly drew reactions from both critics and defenders of the discontinued luxury sedan.

"You know those vehicles are sleepers right?" another viewer replied.

Others were ready to pile on insults toward the Ford product and larger brand components.

"Sleepin at the dealership," one commenter joked.

"Sleepin at the used car lot," another added.

For some viewers, the video seemed to reinforce every stereotype they've ever heard about aging luxury cars. But Lincoln sedan owners were just as quick to defend them.

"My MKZ was the best car I've ever owned," one owner wrote.

Another said his Lincoln MKS had accumulated more than 253,000 miles. Others chimed in with similarly positive experiences.

"They are lowkey really nice interior and looks wise," a Lincoln fan wrote, adding that his father's hybrid model went five years without any significant problems.

The video seemed to be intended as a warning about a specific repair issue, but many viewers interpreted it as a broader verdict on Lincoln's lineup. For every commenter who saw the clip as proof that the cars should be avoided, another pointed to years of trouble-free ownership.

The debate is part of an ongoing discussion among mechanics and owners who have questioned the internal water-pump design, because of both the labor required to replace it and the potential consequences if coolant contaminates engine oil.

Prepare For More Maintenance Costs

For prospective buyers, the video serves as a reminder that reliability and maintenance needs shouldn’t just be measured by whether a component fails. As important to consider is what steps and costs are involved in repairing a part that has failed.

Water pumps are hard-working wear items that eventually need replacement on virtually every vehicle. The difference is that on many engines the job can be completed without dismantling major portions of the drivetrain.

On Ford's internal water-pump design, however, a decision made by engineers has made life a whole lot tougher for mechanics trying to complete what is normally a fairly routine repair. All the time and hard work for the folks in the garage translates into a far larger final bill for the owner.

For a typical vehicle with an externally mounted water pump, replacement costs fall somewhere in the $400-$1,200 range, depending on the vehicle and labor rates.

Conversely, multiple online commenters have said Ford's labor guide calls for 15.3 hours for the same fix, making a 16-hour estimate reasonable. RepairPal estimates a Lincoln MKZ water-pump replacement at $1,500-$2,100, with labor accounting for the vast majority of the bill.

That reality helps explain why the mechanic's brief video generated such strong reactions. Some viewers saw it as proof that aging Lincoln sedans should be avoided. Others viewed it as a known issue that's manageable with proper maintenance and attention to warning signs.

Either way, the image that impacted viewers the most seemed to be the basin sitting beneath the vehicle, filled with a muddy mixture of coolant and motor oil that looked more like something dredged from the bottom of a pond than a modern engine.
