Radiators

A radiator cover is used to enhance the aesthetics of a room by concealing the radiator behind a decorative panel. It can also help to distribute heat more evenly throughout the room and provide a surface for displaying decorative items. Additionally, radiator covers can offer protection to children and pets from hot surfaces.

you are most likely leaking coolant and if your car should be overheating in a short period of time.

Yes you can use only water but only if you are absolutely 100% sure that the car will not be parked anywhere that the temperature drops below (freezing) 32 degrees F. or Zero Celsius.

If you do park the car in a place where the temp drops below freezing and the water freezes you will crack your radiator and also this could crack the block of your engine too.

So as a rule, if you live where it could freeze then you want to put Antifreeze in with the water; usually 50/50 (read the bottle). The mixture varies depending on how cold you anticipate the temp will get where the car is parked.

If you havent got any antifreeze you can put just water in , and this could last you all summer and into the fall, but just remember to drain some out and get the right amount of antifreeze in there before winter comes.

I learned the hard way as one summer I filled my car with just water in the radiator, and as winter approached I kept telling myself that I better put in some antifreeze. Well, I kept putting it off and then sure enough; one morning I noticed some rain puddles in the driveway had frozen over, and so to was my radiator. The ice destroyed my radiator as water expands when it turns to ice, Luckily it didnt destroy the whole motor as it was not that cold say perhaps 31 deg F. also I noticed it early. If I had left it much longer the motor would have been destroyed too.

By the way, you can even use just water in the coldest of winter, as long as you never turn off the car long enough for the water to freeze.

So yes, in a jam you can use just water, but if you park the car and it freezes you'll be sorry. Now you know why they call it anti freeze! Anti freeze performs the same function as the water does (heat transfer); however, it is designed (chemically) to have a much lower freezing point (than water).

your local auto zone or other parts store should have somthing you put in your radiator to plug it but this is only temporary if the hole gets any more than somthing like a pinhole you will have to replace the radiator

There may have been some Bar's leak/stop leak added at one time. Flush system. If that's not the case and it's a milk shake consistency, then you could have a bad head gasket allowing oil into the coolant.

sounds like your head gasket is blown...

It,s circulated there from the hot engine block and cylinder head by the pipes, hoses and the engines water pump. It could be up to 230 deg F

Usually a radiator hose is not repaired though replaced can cost minimal of a couple of dollars to a lot of dollars depending on the hose to be replaced

Yes, It's very tricky and takes time to do it. Process called Thermo Welding. There is many DIY guide on the Internet. basic 101 about thermo welding...

You have two options.

1st option is to buy professional plastic welder kit (starts $50-$300) that will melt plastic parts and fuse it back as one new solid part.
how does it work!
Simple you heat whole area where plastic welding will place, then once you reached required temperature for the plastic that you weld, use your plastic welding gun and the plastic ROD (ROD is new material that will be added to the welding process)
BTW very important you can only weld SAME type of plastic together, mixing it with other types of plastic may cause bad results.

Once you have both radiator and new ROD heated they will slowly join them self.

This is not easy but works,

2nd option: instead buying plastic welder you can try to use adjustable temperature or none adjustable soldering iron. On none adjustable soldering iron you have to play with the distance of the tip so you always have same temperatures on the part's it's very important to reach correct temperature for this to get successful results.

I hope this little info will help.

Rust, most likely.

Usualy anodised iron, a Spring, and neoprene.

A radiator has no moving parts. It's only job is to dissipate the heat of combustion in your engine. If it doesn't do that job, it's bad. One of the most insidious faults a radiator can have is rust and corrosion build up inside the radiator. This keeps the fluid from circulating. Many times, this cannot be seen. A corroded radiator is a bad radiator. A leaky radiator is a bad radiator; it can't hold the fluid. A radiator with a majority of the cooling fins bent so that air can't pass through is a bad radiator; it can't cool the fluid. One of the tests they do on radiators is to pump them up with air and listen for whistling leaks. Sometimes, they submerge them in a bath to see if any bubbles form, and if they form, where they're coming from. If bubbles do form, it is a bad radiator.

Ours just ripped open on the highway. Do not try to repair, as it will rip again at the wrong time.

The basic rule of thermodynamics is that heat goes from where it's hot to where it's not. The coolant in a vehicle takes (draws or sinks) heat from the engine, and this heats the coolant. The hot coolant carries off the heat, and then flows through the radiator. Air passing the elements of the radiator, because it is cooler, takes (again, draws or sinks) heat from the radiator's fins, which transfer the heat of the coolant out. The hot coolant loses heat energy as it flows through the radiator, and heat from that coolant is passing through the metal radiator elements into the air flowing past. The radiator sets up a relatively large surface area to that passing air so that "a lot" of heat transfer can take place. There is what is called a thermal gradient across the elements in the radiator. Hot coolant inside and relatively cool air outside those elements set the ends of the gradient. Heat goes from where it is hot, the coolant, to where is it not, the air. If you guessed that there must also be a thermal gradient across the metal of the engine between the combustion chambers and the coolant chanels in the block and head, you'd be right. That thermal gradient drives heat out of the cylinder walls and head into the coolant in the coolant channels. It's just that simple. Remember that any time a temperature differetial exists, a thermal gradient exists. A thermal gradient is the "force" of heat transfer in the science of thermodynamics. Easy as pie.

For a Sedan (Car) approx 3 Gallons, for a truck or Suv, 5 gallons, it varies slightly depending on the size of the engine, (4 cylinder less, a V8 more), to know the exact amount check your users manual, or contact the Manafacture.

Sounds like you got a leak - need repair

yes

if you haven't already go to your nearest auto parts store and find a chilton manual for your vehicle.

Keep it in there, you will need it.

Yes.

Early beetles (original - not new beetles) are air cooled - they have a large fan, big cooling fins on the cylinders and a ducting system ("tin" to vw nerds) that direct air around the cylinders to cool the engine. Also an oil cooler ( a mini radiator within part of the tin duct system) that the oil circulates thru.

i want to know this aswell >.<
