open the drivers door the answer is there on a sticker. every car has this.
According to one of Fords websites : For a 1994 Mercury Villager , 3.0 liter V6 : The radiator cap is ( 13 PSI )
29.0 pounds per square inch is about 59.05 inches of mercury.
The MAX PSI cold-inflation level for your tires is stated in lettering on the sidewall of the tires.
Inches of mercury x 0.4912 = psi
Multiply by 2.03625437 to convert from psi to inches mercury. Multiply by 0.49109777 to convert from inches mercury to psi.
The tires should say it. Usually about 32 psi.
in the 1.9 liter engine it should be from 35-45 psi
30 inches of mercury = 14.73 psi (1 inch of mercury = 0.491 psi So, 30 x 0.491 = 14.73).
34 PSI, but I the tires should have the suggested PSI written on the side of them.
14.37 psi is 0.20317789 inches of mercury.
With key on engine off 23-31 psiWith engine idling 13-20 psi
32 PSI
