AS the antifreeze or coolant ages, there are chemicals that become acidic. Although radiators are somewhat resistant to corrosion, your coolant SHOULD be changed every 2 years with a complete cooling system flush.

Why must a car radiator have a high corrosion resistance?
Car radiators generally don't have a high corrosion resistance.Lately, radiators are being made from aluminum. Aluminum 'rots' quickly in the presence of other metals and a good electrolyte. For that reason, it is important to use a coolant in the recommend concentration that is formulated to prevent this. It is an extremely good idea to change the coolant every two years because the chemical additives that protect and lubricate become depleted.
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
Which electrical device must have high resistance in order to function properly?
voltmeter
Why does voltmeter have high internal resistance?
No, ammeters have a low internal resistance. This is so that when they are put in series with a circuit, they change the circuit's operating characteristics as little as possible.Contrast this with voltmeters, which do have a high internal resistance, and which are intended to be placed in parallel with the circuit they are measuring.Use the link below to the related question on why ammeters have a low internal resistance and read through that information to see why things are the way they are.
What can you do to stop the plug on your electric heating from getting red hot?
You must have some high resistance in the plug or outlet, make sure that all connections are clean and tight, clean off any corrosion or burns on the plug, may have to replace outlet if contacts are burned in outlet. This is a fire hazard.
What kind of the best material of UV tube?
There is no doubt that the quartz is the best material on UV lamp. The quartz not only have high thermos ability and corrosion resistance, his softening temperature is 1730℃, which can be used for a long time at 1100℃, especially the chemical stability in the high temperature, is any other materials cannot match. The SiO2 is the main ingredient of quartz, must to be 99.9%.
How can I passivate stainless steel parts?
Passivation is the process of maximizing the corrosion resistance of stainless steel products. To do this, one must clean the product, run it through passivation baths, clean it again, and then test the product.
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
What does a megohmeter or megger test?
It checks resistance from a circuit or an electrical component to earth, to make sure it is electrically isolated. This must be a very high value of resistance, hence 'megohms'.
How can i stop radiator coolant leaks?
If the hoses are all tight, Then the radiator must be leaking. REPLACE RADIATOR
What wire will allow high current to pass through without getting hot?
A wire with low resistance. To obtain the lowest resistance, the wire must be -- thick -- a good conductor; silver, copper, etc. -- cold
Where is the radiator petcock on a 2004 silverado 5300 v8?
Most of these do not have one.You must remove the lower radiator hose to drain the radiator.
