Assuming that your gauge is accurate, then you probably have a stuck thermostat in the open position that is not allowing the coolant to stay in the engine long enough to reach proper operating temp. Replace the thermostat or have a good mechanic do it for you.
Actually, that's 68 degrees F, and that's only for black & white film. Color runs at 100.4 degrees F--or 20 degrees C (B&W) and 38 degrees C (color). As to the rest of your question...the temperature you use isn't changed by the number of exposures on the roll.
The Prime Meridian of the world lies at 0˚ longitude.
There is only one Prime Meridian. It's an imaginary line on the surface of the earth that runs between the North and South Poles, and passes through the Royal Observatory in Greenwich, England. It's the official "Zero" line for east-west measurements; the 'longitude' of every place on earth is expressed as degrees "east or west of Greenwich". The USA ... not counting Alaska or Hawaii ... lies between roughly 67 degrees (Maine) to 124 degrees (California) west of the Prime Meridian.
East and West technically don't end or begin, but there are lines of latitude that show where the Eastern and Western lines of latitude begin and end. The Prime Meridian, (0 degrees) runs through Greenwich, London, England, and any line of latitude away from it is labeled with the corresponding direction from the Prime Meridian. East and West lines end at 180 degrees, directly opposite the Prime Meridian.
Yes and it should be in your fuse block. Chances are that it is a relay fuse and you won't be able to tell if it is blown or not.
It is under neath the engine cradle and runs the same way as rear axle.
My 03 runs up to 225 degrees,sometimes a little concerning.
A steady 20-25 at idle My freshly rebuilt 2.8 runs at 22.
It will depend on the year, make and model but on older vehicles it runs on the average of 165 to 195 degrees and on the newer ones between 195 to 235 degrees.....
The 60 degrees east line of longitude runs through the Ural Mountains.
10 degrees
360 degrees. Longitude runs from 180 degrees East to -180 degrees West.
The Tropics of Cancer and Capricorn
The engine runs fast, won't idle down, and many times the exhaust manifolds will glow red hot from the lean mixture.
A clogged fuel filter would be the most likely suspect.
Depends on what year 350. It can be 2 degrees BTDC or 4 degrees BTDC. I would try 4 degrees and see how it runs.
Usually you know it's time to change it when your car runs too hot because the thermostat is stuck closed. To test if a thermostat is bad check the following: Start to open between 169-176 degrees F(76-80 degrees C) Fully open at 194 degrees F (90 degrees C) Valve lift at fully open should be 8.0 (0.31) min.
