How can I get dust out of my radiator?
Place a towel under the radiator (in order to catch any dust) and begin to push the stick down the back of your radiator, from top to bottom, pushing dust and dirt out until clear. Repeat this on each section of your radiator, until you have cleared most (if not all) of the dust away.

What is the directivity of an isotropic radiator?
The directivity of the hypothetical isotropic radiator is 1 or 0 dB. The directivity of a half-wave dipole antenna is 1.64 or 2.15 dB. The radiation pattern of a wire antenna of short length compared to a half wavelength is shown in Fig. 3.1 A.
How often do you need to clean your Radiator?
Really dirty heaters can be a risk to your health and will only offer reduced heating capacity, so if you feel you can’t do the job yourself, bring in an expert once a year to do it for you.

How to remove lime deposits in an auto radiator?
Add antifreeze to equal 50 to 70 percent of the total capacity. For example, if your cooling system holds 10 quarts, add 5 to 7 quarts of antifreeze. Top off the radiator with distilled or demineralized water. Screw on the cap and run the engine until the coolant is circulating through the engine.
Where is the bleed key on a radiator?
