A quick and easy way to check if your radiators have any air in, is to place your hand on or near the radiator (careful don't burn yourself) and check for any cold spots. If you feel a difference in temperatures, you will need to consider bleeding your radiator to allow any air to escape.
Engine Overheating
If the temperature gauge in your vehicle is rising higher than usual or if the engine warning light comes on, these are both indications that your radiator needs to be checked out. Another sign of radiator damage is a leak in the system.
Make sure both the valve on the left and right of your radiator are open, and if you have a thermostatic valve (one that allows you to set the temperature and adjusts it automatically), make sure the radiator is turned on. Thermostatic radiator valves can also seize up, causing your radiator to stop working.
The quickest way to balance central heating radiators is to make adjustments to the lockshield valves attached to them. If you would like one room to heat up quicker than others, the lockshield valve should be opened slightly more on the central heating radiators within this room.
Radiators need a thorough inspection at least once a year, the best time being just before the start of the winter. Any professional plumber can do this, but it is advisable to make it a part of the annual gas safety check, which needs to be done by a gas-safe registered engineer.
If your central heating system stops working because of a fire or a storm, or if someone vandalises your home, you may be able to claim on your home insurance. Home insurance provides cover for both the fabric of your home and its contents.
For example, the first radiator should be opened 25%, the second by 30%, the next by 40% and so on until you reach 100% on your last radiator. Depending on how many radiators you have, try to spread the opening percentages evenly throughout your home.
This uneven performance can be identified by a number of identifiers such as; cold radiators or uneven temperature across an individual radiator, different temperatures of radiators throughout your home, or excessively long times to reach a desired temperature.
Look for leaks and cracks in your radiator hose every time you change the oil in your car. Check also for rusted clamps and make sure your gasket that's fitted to your radiator cap is still ok. Look for visual signs of leaks or drips under the engine.
You should bleed your radiators at least once a year, typically before winter arrives in order to ensure the efficiency of your heating system. Regularly checking for trapped air also helps to make sure that your system operates effectively and reduces energy consumption.

There are a few signs that your radiator might be blocked. If your car's engine is running hot, this is a definite sign that something is wrong. You might also notice that your radiator hose is hot to the touch or that there's steam from under your car's hood. These are all clear signs for radiator replacement.
While the process of balancing radiators can be relatively simple, it can be daunting to do if you've never done it before. This is where a professional heating and plumbing expert can help.
Most radiators have two valves, one that lets the water into the radiator, and one that allows the water to be removed from the radiator. Familiarise yourself with both valves and their operation. Both valves should be turned fully open (anti-clockwise) so that the water can flow freely through the radiator.
If your radiator is severely damaged, it may need to be replaced entirely. This is a more involved repair that will take longer and cost more than a minor repair. In some cases, it may not be worth repairing the radiator at all; if the damage is severe enough, it may be best to simply replace the entire engine.
According to Fixr.com, the average cost nationally for a house radiator replacement ranges from about $1,000 to $3,500, though some replacement jobs can be accomplished for as little as $500 on the low end and as much as $8,600 on the high end.
Earthquake, flood, mold, earth movement, and “wear and tear” are some of the perils that are usually excluded.
However, the vast majority of radiators will eventually get to a point where they are beyond repair or restoration and will need to be replaced.
