When one mentions a radiator, one would think of that silent ubiquitous metal air-conditioner type of grill, like out of the refrigerator itself. And you wouldn’t be far from the truth, dear Reader. In fact, the purpose of this grill-like object in refrigerators and cars are both the same: draw heat away from the engine.
How is hot water cooled in the radiator?
Radiators are by definition “convectors” or “heat exchangers.” Radiators mostly involve liquids and changing the temperature of these liquids from hot to cold to hot and so forth. The goal of a car radiator is to draw heat away from the engine and replacing the environment with cooler water drawn from the radiator.
Radiators are located front of the engine and behind the front grill of the car. This puts the radiator in a position to receive relatively cold outside air. Radiators have fins sticking out from the pipes to increase the surface area where air can come into contact with it, this way warm liquids in the radiators get colder faster in time to be pumped back into the engine to draw more heat away.
What’s the composition of the radiator liquid?
Inside the radiator is plain water mixed with coolant. The ratio is about 50:50.
As a word of caution, NEVER put coolant when the engine is hot. Wait for the engine to cool down before putting in coolant. Doing so may crack the engine due to extreme temperature differentials.
Putting plain water in a hot engine is allowed during emergencies.
Coolant is needed as a part of the mixture because it has anti-corrosive properties, saving your radiator from early rust.
How to check and add liquid to your radiator
Here are the steps on how to properly check and add liquid to your radiator.
Open the radiator cap. NEVER open a radiator cap with the engine hot, this is a sure way to get very hot steam in your face. If you cannot wait, pour cold water over the cap and the radiator to facilitate in cooling the radiator faster and safe enough to open.
Look down into the hole and check water level. You should be able to see that the water level has to be around an inch below where the cap screwed on. This means that the water level is fine.
Any lower, or if you see the water fellow the fins in the radiator, it’s time to add some liquid.
Check fluid condition. You tell a lot by looking at the quality of the fluid inside a radiator. The regular color of fluid is like juice, orange, blue or green. Vibrant colors.
If you notice that the fluid color is colorless (and you did remember to put in coolant), rusty, or has some particles floating around inside, it’s time to flush the fluids and add new water and coolant into the radiator
If you see the fluid quality is oily or sludgy, drive the car immediately to the mechanic or service center. This may be a possible leak with the internal head gasket.
Check hose conditions. Feel and squeeze the hoses for that familiar rubbery feel. If they are in any way cracked, brittle, spongy, porous, or bloated, it’s a good time to replace them.
Add some liquid in the radiator. The rule of thumb when you place fluid in the radiator is 50% water and 50% coolant. The coolant is important, not only to keep the engine cooler than what just water would do, but also to stave off the attack of rust on metal.
What if I need to totally replace (flush) the radiator?
Coolant is TOXIC to living things. Do not just flush them into your drain.
Follow these steps:
Make sure that the engine is cold before proceeding. Park in a place where you can work with no children coming near, especially toddlers.
Place a bucket under the drain valve of your car. Make it enough to hold at least 6 liters.
Open the drain valve and allow the liquid to fill the bucket.
Close the drain valve.
Open the radiator cap and fill with plain water.
Run then engine with heater on high for 10 minutes. Keep an eye on your temperature gauge to prevent overheating. Allow the engine to cool and drain into the bucket all over again.
Refill the radiator with 50% water and 50% coolant.
Replace radiator cap and run the engine with heater on high until the engine comes to your usual temperature range.
Shut off the engine and allow to cool once more.
Bring the used radiator fluid to your local service station for disposal.
Every week, re-check the radiator for water level once more and fill as necessary.
There you have it. You can now do maintenance on your radiator. Easy wasn’t it?

My Canon Pixma printer keeps giving me an error message stating that my ink tanks are not inserted correctl?
I went to cartridge world yesterday to get the magenta tank refilled but the guy at the shop had one that he’d refilled earlier which was the same type as the one I took in so I took that one and thought nothing of it. Last night I printed a document and it came out fine but I tried to print a photo a few minutes ago and I got a message saying “Ink tank errors have occurred, open the printer’s cover and replace the ink tanks on which the lamps are off” but on doing this I found that all the lights were on including the magenta. I have only had this printer since March this year and I’ve never had a problem with it.
Should I take a print screen of the error messages and show them to sales assistant (I can print them off at uni in the morning) or will I have to take the printer in to prove that it doesn’t work, the store is not far from where I live and the printer doesn’t weigh much.
It’s the iP3300 model
Just take the cartridge and the error message, that should suffice
