Radiators

First of all use an airline blowing from the rear through to the front of the radiator,then using a brush ie paintbrush ,on the front fins to gently clear any loosend debris but not forcing them further into the radiator. Repeat as nessesary ,you may have to use some degreaser or mild diluted washing up liquid to clear dried on residue. But be careful to not damage the fins of the radiator as they are more delicate than you realise.

im the one asking the questoin

There can be many reasons why a car surges while idling. Some of these reasons are the computer could be dying, or the fuel injector are giving the engine too much gas.

question- what was the car without a radiator? well it's probly a car without a stinking radiator,,,

Yes, a car needs a radiator to run because it stores the coolant for the engine and dispenses it when needed. So, if it didn't have one the car would overheat and not be able to move :)

What would happen is when your vechile begins to run and gets warmed up your fluid will splatter all inside the hood of the vechile and your fluid will run low and it will crack your radiator.

Wrong PSI radiator cap or defective radiator cap installed.

NEW ANSWER: The above answer is true ( COULD BE ) But I would bet you have a BLOWN / LEAKING head gasket that is building pressure in the water / cooling system.

It is widely accepted that you should replace your antifreeze every two years but you can buy a hydrometer to check it to be sure. After prolonged use, antifreeze will beak down and become very corrosive. It can lose its rust preventative properties and the cooling system can fail.

Under the hood

Aside from broken hoses, coolant leaks may occur in the radiator, water pump, thermostat housing, overflow tank, freeze plugs (in block), the head gasket (into combustion chamber(s) and/or crankcase) or simply a cracked block. An old radiator or blown water pump seal are the most common or frequent source(s) of coolant leaks after hoses. Placing a white sheet of paper (or even newsprint) under your engine overnight may help locate the source of a leak. Coolant is green. Otherwise, be certain that you have inspected ALL hoses. Coolant hoses on some automobiles or light trucks may be located under or behind other components and not visually obvious at first glance, especially toward the rear of the motor. Also, be sure that all hose fittings are tight. Check the thermostat housing gasket, too. This is a domed fitting on top of the motor where a radiator hose attaches. Don't forget the overflow tank, clear plastic typically mounted to fender wall. The water pump is belt driven, typically located at the "front" of the engine and may have a radiator fan mounted to it (as opposed to an electric radiator fan which will be mounted to the radiator itself). Inspect the water pump shaft and housing behind the pulley for signs of leakage. Typically there will be a tiny (3mm) "weep" hole to indicate a failed seal. If the bearing goes, fluid may leak out around the shaft. It will also sound like marbles in a can. Visually inspect the radiator for corrosion which may form around cracks, especially on the radiator passages between the rows of cooling fins and where those passages join the side tanks, as well as where the intake/outflow pipe fittings join the side tanks. There is also a drain plug that is typically threaded. Make sure it is tight and not leaking. If nothing is apparent, run the engine to operating temperature (HOT) and look for small wisps of steam, bubbles or dribbles around the radiator. If the radiator appears clean and dry... Locate the freeze plugs in your engine block which may have been dislodged. There are typically (3) located along the lower sides and one in the front and rear each. Finally, check the engine oil dipstick for a frothy milkshake appearance from coolant mixing with engine oil which would indicate a leaking head gasket. This will be most obvious when the engine has been sitting overnight. If the engine has been running, the oil may appear "smeared" with bright colored streaks on the dipstick. If this is the case, have your engine serviced ASAP as coolant in the engine oil is very dangerous for the engine. Good luck.

Rust and sediment can accumulate in the cooling system. Flushing the radiator helps keep the cooling system clean.

If the problem your having is in your 'cooling system' , flushing it out could help out a lot.

The cooling system on you car's engine is pressurized to reduce the evaporation temperature of the fluid, to make the system more efficient. If you open the radiator cap when the engine is hot, the fluid sprays out as the pressure equalizes. This can burn the s##t out of you, seriously. It's dangerous and wasteful of the coolant fluid. WAIT, an hour or so, to let the engine and readiator cool off, before taking off the cap. Then you can add water/coolant mixture. DO NOT PUT ONLY WATER into the system! Use a mixture of coolant and water, or straight coolant from the bottle.

Your radiator might have a small pinhole in it, causing it to not build up pressure.

No. It is a fictional town in the animated movie Cars.

An automobile's radiator fan will switch on and off during normal operation of the vehicle, and sometimes after the vehicle is shut off. The fan is controlled by a thermostat that regulates the temperature of the coolant in the radiator. When the coolant rises above a certain temperature, the thermostat switches the fan on to cool the radiator until the temperature drops below its limit and shuts off. The fan turning off and on is a normal part of the car's operation and is nothing to be concerned about.

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.

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.

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).

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
