Engines are a lot like the human body, which is a pretty noisy thing if you listen closely enough. A gurgling sound coming from under the hood could indicate a lot of things from the mundane to the very serious. Odds are good though that it's nothing to lose sleep over or a simple fix. Generally speaking, gurgling noises are the sound of air or water moving around in your cooling system. This tends to happen most when the engine is very hot, and is very common after shutting a hot engine down.
In this case, the sound you're hearing may just be water and steam moving to and from the coolant overflow bottle, or through the cooling passages. Gurgling noises are often associated with overheating for this reason, but you'll know if that's the case according to your temperature gauge.
If the problem is persistent, try bleeding the air out of your cooling system, since trapped air bubbles are a major cause of both overheating and gurgling. It's common to hear gurgling under the dash if there's air in the system -- coming from the heater core. In terms of severity, the problem could be on either side of that.
Some engines are just known to burble, and the noise gets more pronounced when you install something like a short-ram or cold-air intake. If this is the case, react grid fixed column nothing to be concerned with.
Of slightly more concern are serious potential failures, like blown head gaskets and cracked engine blocks. Odds are good that these will exhibit other significant symptoms, though. Check the coolant with the radiator cap open; if you see oil floating on top, or smell gasoline with the engine running, you may have a serious problem in the bowels of the beast.

These are the five most common car air conditioner noises drivers report to their mechanics during service:. Loud squealing or screeching is the most common noise drivers experience when they turn on a malfunctioning AC. This sound often signals an issue with your drive belt or serpentine belt. The serpentine belt is responsible for turning the pulley at your air conditioner compressor, which pressurizes the refrigerant lines and makes it possible for cool air to reach your cabin, among other duties.
Though squealing or screeching is a good indicator of a worn belt needing attention, you can examine your serpentine belt for signs of wear like cracks and tears, or missing ribs facing the pulley, before you bring your car in for service. This next car air conditioner noise is also very common -- but not necessarily bad. A refrigerant like Freon moves between these two separate sides which are divided by either an expansion valve or an orifice tube. Turning off your car will cause the Freon to move from the high-pressure part of your AC compressor down to the side with lower pressure to equalize out.
Your AC will not be able to properly cool your vehicle and it may cause serious damage to your compressor or other components. Get your vehicle checked out ASAP. Hearing a knocking or clicking noise in car air conditioner is actually one of the easier sounds to fix on your own.

You arrive at your destination and park your car, turning the engine off. Well, it may be a problem or it might be normal operation. The most common source of this sound is your coolant system, particularly if you have an expansion tank attached to your radiator.
These systems work a little differently than those on other vehicles. In a basic coolant system, the coolant is locked into the radiator, with nowhere to go as it heats. Your expansion tank is connected to the radiator, usually by a hose through the radiator cap, but sometimes in another location.
As the coolant heats and expands, some of it spills over into the overflow tank. When the coolant cools and condenses, it moves into the radiator. Both of these can cause a gurgling or bubbling sound, and are completely normal.
This can be a problem — air trapped in the system can cause your car to overheat. There are several ways to bleed air from the coolant system, including using a funnel on the radiator attached to a special tool that allows mechanics to run the engine while filling the coolant. There are also bleeder valves located on the coolant lines notably at the back of the engine that let you bleed air out.
Blown Head Gasket: A blown head gasket can allow exhaust gases to enter the coolant, which becomes trapped in the system and can cause a bubbling or gurgling sound during operation.
Low Coolant: If your coolant is low, then air moves in to fill the void left by the missing coolant. Again, this creates air pockets in your system, which cause the gurgling sound. Low coolant is generally caused by a leak or several leaks, including from cracked hoses, a leaking water pump gasket and many other possible locations. One of our highly trained mechanics will come to your home or office to inspect your radiator, coolant level and listen to the gurgling noise.

I checked and there was a puddle of antifreeze on the ground of the garage. I refilled the resevoir and started the car again letting it run for 15 mins to get the antifreeze through the engine. I looked under the car and noticed it was dripping to the ground. I could not see where it was coming from but the resevoir was empty.

By the way, by filling the reservoir and letting the engine run you were not getting coolant into the engine.
The only way it gets there from the reservoir is when the engine cools and contracts, drawing fluid back into it through the radiator cap.
This is because the engine is as hot as it was when you were driving, but the coolant is no longer circulating through the radiator, and the fan is not running. Many owners of older cars such as yours install electric cooling fans that come on for several minutes after the engine is shut down to compensate for this rise in coolant temp.
When coolant is hot is expands, and the relief valve in the radiator cap allows it to flow out of the radiator into the overflow tank. This can make a bubbling noise. Once the engine and coolant cool down, the coolant contracts and this will suck the coolant back into the radiator. This is not to rule out something more serious, certainly if this condition is new to your car and you have had it a long time, then follow all the previous advice to avoid major damage to your lovely old car.

A car engine can make a variety of noises. Because there are many fluids and mechanical parts which get hot and cold there can be a gurgling noise which is caused when problems arise. In general gurgling noises are causes by internal fluids being forces through a chamber along with a mixture of air.
Some gurgling noises are normal which are described below. Park your car on level ground while the engine is off and in cool condition. To start repairs an inspection is needed first so its a good idea to have a flashlight and a set of gloves. Try to listen to the noise and see where it is coming from so you can get a better idea what the problem may be if any.
Check for an Engine Overheating: When an engine runs hot or overheats it can cause a thermo lock in the cooling system which can produce a gurgling noise inside the engine radiator. This can be due to a stuck thermostatblown head gasket or a coolant leak. When an engine overheats it can force coolant into the overflow container which can create a bubbling sound.
This can also be caused by a faulty radiator cap. Never check the coolant level until the engine has cooled completely. Air can be sometimes naturally trapped inside the system so look for a bleeder screw on one of the cooling system components such as the thermostat housing.
Air in the Power Steering Fluid: The power steering system utilizes hydraulic pressure which is produced by the power steering pump. If the fluid level is low it can pull air into the system causing a gurgling noise due to the air bubbles in the system.
Check the power steering fluid level by locating the fluid reservoir and remove the cap twist counter clockwise. If the fluid level is down or there is no fluid in the reservoir the system has a leak.
Inspect and replace a leaking power steering pump or hoses and rack and pinion or box assembly. Replace worn or broken components as needed and refill system with manufacturers recommended fluids. Allow the system to stand for a period of time to allow air aeration to dissipate. Air in the Heater Core: While the engine is running coolant is being pushed through the heater core. When air bubbles get trapped they can make a gurgling sound in which case the front or the rear or the front of the car must be jacked up to pure the bubbles from the core.
Air in the heater core can also be caused by an excessive volume of coolant being circulated through the core. The heater core is design to have restricted coolant flow to minimize these bubbling sounds.
To repair this condition a flow re-stricter must be installed on either the core input or outlet hose. Gurgling When the Engine is Shut Off: Engine oil is circulated throughout the engine when is running.
When the engine is shut of this oil which is located in the cylinder head will drain down and back into the oil pan. This is normal and should not be thought as a problem.
