Yes. The fuel gauge in most vehicles will settle at 'empty' with the ignition off.
Trust me, it works. Your problem is the fuel level sensing unit connected to your fuel pump. Change your fuel pump and your problems will be solved.
Have it checked for codes, it will probably have to do with the fuel level sensor in the fuel tank.
Add 4.5 quarts 10w30, start engine, check and adjust level.
Same place you check the fluid level.
check coolant level
Check the fluid level. Check the linkage. Check all computers for trouble codes.
Check coolant level in rad on cold engine. If low you gort a leak. If level ok, replace thermostat and gasket
That depends on how much gas is in the tank and what the angle is.
To check the differential oil level, remove the top plug from the back of the differential (some are rubber push-in pull-out type, others may be metal threaded type). Use your finger or a clean stick to check the level. It should be up to the bottom of the hole (or nearly).
No, it just means that the fuel level sensor is malfunctioning. Your gas gauge may not read properly.
Inside. You should always place your rain gauge outdoor in a nice open space where there is nothing to hinder the rain falling directly into the gauge. Mount the gauge vertically and level, and check and empty it after every rain fall.
Buy a kit at Wal-Mart or auto parts comes with a gauge - level is dependent on pressure which is directly influenced by ambient temperature
