Bernadette's sleeve catches on fire (in the scene where she confronts the witch) and she races outside to put it out in a tub of water. After she does this, you can clearly see that the sleeve is completely destroyed - but when she gets back to the station, there's no damage to her uniform (outside of being dirty and sweaty).
When Chee stops to help the elderly whose truck is overheated, he opens the radiator cap and pours water into the radiator without starting the engine first. In old style cooling systems without a reservoir tank outside the radiator, this can crack the engine block as the colder water enters into an empty radiator and goes into the water jacket without being pumped by the water pump and mixed with whatever coolant remains in the hot engine.
As an aside, he only pours a few ounces of water into the radiator, which wouldn't help at all and could only cause damage.

At the end, as Leaphorn closes in on Nakai under the cover of dark, the camera angle is such that the viewer can see a blue sky above Leaphorn. Though the scene is dark because of the use of a filter, it just does not work. The night sky is ALWAYS black, NEVER blue.
In the commercial, the car salesman refers to the vehicles engine size in liters. In the US in 1971, it would have been described in cubic inches.
The driver who Chee stops to help refers to an "old" Pinto. In the setting of the scene, the Pinto had not been in production long enough for someone to refer to one as old.
In the commercial, the car salesman refers to a car having a 7.7 liter engine. At the time, American car engines were measured in cubic inches. Furthermore, the mentioned vehicle appears to be an Oldsmobile 442. The largest engine offered in a 442 was 455 cubic inches or 7.5 liters, while 7.7 liters equals 470 cubic inches.
The series is set in 1971, but the typeface used for Devoted Dan's signage and business card, Lithos, was created in 1989.
The signage, ENTERING Navajo Nation, uses the Clearview font, which wasn't introduced until 1996. The font used for the highway signage is Highway Gothic.
