(See Fig. A, below, to find the wind zone you live in.) It won't cost a fortune, either. A little elbow grease and the building materials will all but guarantee your family's injury-free survival in any storm that comes down the pike. Keep in mind that a safe room can be more than just a storm shelter.
Expansion Tanks. The expansion tank is a vital part of your car's cooling system and acts as an overflow reservoir catching the water/coolant mix that is forced from your radiator as it heats and builds pressure in the system. cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. If your find yourself having to replace coolant too regularly then check your expansion tank and the rest of your system for leaks.
Fuel Tank Venting. Your tank has to breathe. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. Gasoline expands in volume as it warms up and shrinks in volume as it cools down. The fuel level of your tank changes throughout the day, even if you are not driving it.You cannot put fuel into your tank, unless you can get the air out...and you cannot withdraw fuel from your tank unless you can let air in.Up through the 1960's, most vehicles used vented gas caps. This is simply a gas cap with a hole in it.ou cannot put fuel into your tank, unless you can get the air out...and you cannot withdraw fuel from your tank unless you can let air in.
