If you're talking about the inertia switch, in my 1990 F150 XLT Lariat, it's located on the firewall, driver's side, beside the main wiring harness pass-thru, directly below the brake pedal linkage. It's black, with a red indicator on top. I've used it before to drop out the fuel system so I could disassemble the fuel rail.
The EGR valve is located in the center of the engine on a F150 Lariat 5.4 liter. It is near the firewall.
Mine is 265/70r17
Under the seat ( according to the Owner Guide )
275/65/r18t
no, the ranger is quite a bit narrower than an f150
It's behind the glovebox inside the HVAC case.
The Ford F-150 Lariat has a timing chain, not a timing belt. Unlike a timing belt, there is no need to have the timing chain changed.
30 gallons per tank.
I believe that is 260 horsepower
