How to clean Radiator

Instructions

1. • 1
     Allow the car to cool for 12 hours before attempting to clean the radiator. Unscrew the drain cap at the bottom of the radiator and allow the radiator fluid to drain into the drain pan.
   • 2
     Close the plug and fill the radiator with water. Turn on the car and run the engine until the water circulates completely through the engine. You should be able to see steam. Allow the engine to cool for one or two hours. Repeat the draining and water filling process one more time. Drain the water from the radiator and allow the engine to cool.
   • 3
     Fill the radiator with a radiator system flush. Turn on the heater and run the engine for about 10 minutes. Follow the instructions on the flush bottle if they differ. Some flushes have a slightly different procedure.
   • 4
     Drain the radiator, then fill with water. Run the water through the engine, then drain it. Repeat the flush process one more time.
   • 5
     Fill the radiator with antifreeze. Fill the radiator with 50 percent antifreeze and 50 percent water. Run the engine and heater one last time for about 10 minutes to flush the antifreeze through the system.

     
     

     Tips & Warnings

• Never touch a hot radiator, or put your face or other skin close to the radiator while it is heated. The steam from the radiator can cause serious injuries and burns.

Clear your skin with 7 tips

            Clear skin tip 1: Ditch the chemicals

It can be tempting to reach for chemical peels and ingredients such as salicylic acid to help clear up problem skin. However, many chemical-based skin products not only contain potentially harmful ingredients, they can also excessively dry out skin and exacerbate skin problems. For a gentler approach to fighting acne, opt for natural spot-fighting ingredients such as tea tree oil or manuka honey.  Manuka honey not only has antimicrobial and antiseptic properties to fight spots, it also has the benefit of being able to reduce the scarring and marks left by spots.

            Tip 2: Use spot-fighting makeup

We all know what it’s like to have a bad skin day when you just want to hide away under layers of makeup. However, while makeup can temporarily disguise the look of spots, it can also make the problem much worse. For confidence-boosting coverage that won’t cause flare-ups, make sure you opt for non-comedogenic makeup that won’t clog pores. To further increase the spot-fighting powers of your cosmetics, try using mineral makeup containing zinc oxide, which will fight against acne-causing bacteria.

            Tip 3: Sip spearmint tea

Acne is generally caused by hormones called androgens, which can over-stimulate the sebaceous glands leading to oily skin, blocked pores and spots. To counteract these effects, oral contraceptives are often prescribed to women suffering from acne. However, while beneficial for clearing spots, these contraceptive pills can have inconvenient and even dangerous side effects. Luckily, research suggests that spearmint tea has similar anti-androgen properties, which could help reduce acne and hormone imbalances in women.

            Tip 4: Reduce your skin’s contact to bacteria

You may be surprised at how often your skin comes into contact with dirt and germs that can lead to acne. During the time you are asleep, your pillow comes into contact with makeup, skin oils and saliva, making it a breeding ground for bacteria that can worsen acne. Likewise, unwashedmakeup brushes can spread bacteria to your skin. To minimise your skin’s contact to bacteria, make sure you wash makeup brushes every two weeks and change your pillowcase regularly. Also, avoid touching your face as much as possible and clean your phone with antibacterial wipes before making calls.

            Tip 5: Cleanse your skin properly

If you suffer from oily or acne-prone skin it can be tempting to over-cleanse your skin to dry out oils and kill bacteria. However, cleansing your skin too frequently or using harsh cleansers can dry out your skin, causing flakiness which can clog pores. It can also cause your skin to produce more oils to compensate. Instead, wash your skin twice a day with a gentle, PH-neutral cleanser so as not to destroy the acid mantle of the skin, which protects against moisture loss and bacteria. Remove the cleanser with a muslin cloth to lightly exfoliate the skin.

            Tip 6: Change your diet

Eating a balanced diet with plenty of nutrients and antioxidants is one of the key factors behind beautiful looking skin. However, there are also certain foods you can cut back on or eat more of in order to help get rid of spots. Research suggests that dairy is a major precursor of acne for many people due to the hormones it contains. Plastic water bottles and food packaging can also leach out chemicals which can lead to hormone imbalance. Swap packaged foods for fresh, skin-friendly produce including lots of fruit and vegetables and foods rich in omega-3 fatty acids.

            Tip 7: Find ways to deal with stress

Research findings published in the journal Archives of Dermatology suggest that high stress levels can significantly worsen acne. It is thought that this may be due to the fact that stress stimulates the production of hormones which stimulate oil production in the skin’s sebaceous glands. Stress is also thought to instigate the release of chemicals which can lead to inflammation. To help keep your skin clear and spot-free, try to find healthy ways to deal with stress such as exercise, meditation or pampering. Try to talk through problems with someone else as well to help relieve any worries.

WHAT ARE BLOOD TYPES?

Everybody has a blood type. The most common blood type classification system is the ABO (say "A-B-O") system discovered by Karl Landsteiner in the early 1900s. There are four types of blood in the ABO system: A, B, AB, and O. Your blood type is established before you are born, by specific genes inherited from your parents. You receive one gene from your mother and one from your father; these two combine to establish your blood type. These two genes determine your blood type by causing proteins called agglutinogens (a-GLOO-tin-a-gins) to exist on the surface of all of your red blood cells.

There are three alleles or versions of the blood type gene: A, B, and O. Since everybody has two copies of these genes, there are six possible combinations; AA, BB, OO, AB, AO, and BO. In genetic terms, these combinations are called genotypes, and they describe the genes you got from your parents.

In addition to the proteins (agglutinogens) existing on your red blood cells, other genes make proteins called agglutinins (a-GLOO-tin-ins) that circulate in your blood plasma. Agglutinins are responsible for ensuring that only the blood cells of your blood type exist in your body.

Your genotype determines your blood type.

The agglutinogen produced by the O allele has no special enzymatic activities. However, the agglutinogens produced by the A and B alleles do have enzymatic activities, which are different from each other. Therefore people whose genotype is OO are said to have type O blood, meaning the agglutinogen on their red blood cells doesn't have any enzymatic activity. People with Type O blood have agglutinins a and b in their blood plasma. Agglutinin a helps the body destroy any type A blood cells that might enter the circulation system. Agglutinin b helps the body destroy any type B blood cells that might enter the circulation system.
