Sounds like you have a coolant leak. When cold, put a pressure tester (hand pump with fitting to the radiator neck) and see if you can see any coolant leaking. Once found, fix the leak.

Check your coolant level and clean out your radiator, inside and outside.

My buick skylark is overheating but the fan is still on i just fixed a broken hose clamp and leak and my car is overheating it has never overheated before so why is it doing this if the fan is on?

there might not be enough coolant inside the radiator, i would check that first. also the heat switch might not open so that the coolant cant make its circle.there is a small possibility that the coolant pump has air around it and it cant regulate the coolant around the engine.beware, never open the radiator tap when the engine is hot.if you overheated the engine ( redline that is) you could have done permanent damage to the engine.

Where is the coolant located on a 92 Honda Accord?

In the radiator, coolant recover tank, heater core, and inside the engine water jacket.

What is wrong when the gauge indicates engine coolant temperature over the normal rage?

It means the engine is overheating. Possible causes are, thermostat stuck in closed position, low of coolant, cooling fan not functioning, blown head gasket, clogged radiator inside or outside, or water pump not functioning properly.

Could be,low on coolant, stuck or sticky thermostat, faulty fan clutch, restricted coolant flow inside radiator, restricted air flow outside radiator, broken or missing fan shroud,

Where is coolant reservoir on a 1992 Lexus ES300?

Coolant reservoir, or directly in the radiator. If you are having to add much coolant, you need to find out why. Serious engine damage can occur if it is leaking inside the engine.

How does an automobile radiator system work?

The radiator consists of cooling fins around tubing which the coolant flows through. A water pump circulates coolant from the radiator through the engine. A smaller radiator around the dashboard makes up the car's heater. An automotive cooling system has 6 basic components; the radiator, coolant/water, pressure cap, expansion tank, thermostat, and the water pump. When an engine is running, the water pump circulates the engine coolant inside the engine. As the engine heats up, the thermostat opens (usually at above 160 degrees), which allows the engine coolant to be pumped into the radiator, through the top radiator hose. The coolant flows through tubes inside the radiator, and is cooled by air passing over the car's grill. The cooled coolant exits the radiator and reenters the engine through the bottom radiator hose. The pressure cap holds the entire cooling system under pressure, which allows the coolant to reach higher temperatures without boiling. The expansion tank holds extra coolant for the system and allows for extra capacity when the coolant expands with the heat.

Where is thermostat for 1998 Ford Escort?

Follow the top radiator hose from the radiator . The hose connects to the engine coolant thermostat / water outlet assembly bolted to the engine . The engine thermostat is inside the housing

Why is my car overheating and get no heat inside the car?

You are probably low on coolant. You need coolant to heat the cabin and cool the engine. Add more coolant and take your vehicle to a shop to find/fix the leak.

What does engine coolant do?

Transferrs heat from the engine to the radiator the to the air it also transferrs heat to the heater core for warm air inside the vehicle

1988 olds 98 regency brougham with a 3800 v-6 it starts missing then the temp light comes on then it dies what could this be it is full of antifreeze?

Engine OverheatingWhen an engine is overheated, it is common that it will begin to miss. The engine over-temperature "idiot" light, and the fact that the engine dies, suggests a confirmation of overheating.You ask, how could it be overheating if it it full off coolant ["antifreeze"]?There are several possibilities as to cause [all based on lack of proper coolant flow] and the following are those that I can think of at the moment:A collapsed or damaged radiator hose restricting coolant flow.The coolant thermostat is not working properly.There is an accumulation of "trash" and "debris" and/or corrosion inside the coolant galleries [passages] in the engine, head (s), and or tubes of the radiator.If the vehicle is equipped with an electrically operated radiator cooling fan, the fan is not operating [bad sensor switch, loose or disconnected connector, cut wire, "bad" fan motor, etc.].Again, there are probably some other causes I can't recall now.

Why is your chevy s10 overheating?

Could be, a stuck closed thermostat, low on coolant, bad head gasket, cracked head, restricted coolant flow inside radiator, restricted air flow outside radiator, missing or broken fan shroud, fan clutch inoperable,

How does transmission fluid get into engine oil?

It cannot get in the engine oil unless you put it there. Trans fluid is cooled thru a cooler inside the radiator tank, or a remote heat exchanger, circulating inside engine coolant. and if optional an isolated fin cooler in front of the radiator.

What can happen if coolant doesn't get changed?

Old coolant begins to break down merely because of the conditions within the engine, being heated and cooling down all of the time. And it can become polluted with dirt and rust particles. Eventually this causes damage to the inside of the engine and radiator, it can clog passages causing the engine to overheat, and cause the engine block and radiator to rust badly from the inside out.

Where is the drain plug for the engine coolant in a 2001 Ford Escort?

Virtually all automobiles have a drain plus (petcock) on the bottom of the radiator for the purpose of draining coolant. Your car should have that on the inside of the radiator, on the botom, on the driver side of the car.

How does the fan work?

If the question is about the motor fan or engine fan, the main function of this fan is cooling the radiator of the engine which in turn is cooling the water circulating inside the engine unto the radiator and back. This keeps the engine at a fairly operable temperature without overheating and damaging damaging its parts.

What causes coolant to boil and overflow?

Engine coolant temperature is cooled by the radiator, moved by a water pump and controlled by a thermostat. If there are troubles with any of those components the coolant will boil Also if the head gasket goes bad gasses from combustion inside the engine will get into the coolant and cause it to boil.

Can you use water for engine coolant?

Water will evaporate eventually. Also water will cause rust to the inside of the cooling system and cause overheating problems eventually.

Why is oil in coolant bottle?

Does it have a oil cooler on the engine ?? If it does then oil runs through tubes that are inside of the radiator to cool the oil, and the tubes are leaking oil into the engine coolant. REPLACE RADIATOR. Really need to know what you are working on. Engine size and year. It could verywell be something else. Let us know NEUTZ.

Is there any way to clear antifreeze from top of pistons without disassembling engine when cylinder head gaskets leak?

Remove spark plugs and crank engine to blow coolant out. Put plugs back in and start engine. Pull inside garage to repair, or leave radiator cap loose and take to mechanic to replace gaskets if engine is not overheating too quickly to get it there.

What does the thermostat on a car do?

The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.

Water pump leak oil in radiator?

You did not say what you are working on, YEAR AND ENGINE SIZE. But in most cases or designs the water pump can not leak oil into the coolant. The water pump has nothing to do with the engine oil. Does the engine have a engine oil cooler on it ? That would be 2 oil lines just above the oil filter that runs down the side of the engine oil pan a go to the radiator. There are tubes inside of the radiator that oil flows through and they are none to leak oil into the engine coolant that's inside of the RADIATOR. If they are leaking then REPLACE RADIATOR. BUT like I said I don't know what you are working on. Would like to help you with your problem, But need more INFO. NEUTZ.

Does the thermostat control the heat in your car?

No, the thermostat controls the temperature of the engine coolant. As long as the coolant temperature is below the thermostat set-point, the thermostat remains closed. Once the temperature arrives at the set-point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The heater control valve allows more or less of the engine coolant through the heater core. Since the coolant should be very near the set-point temperature of the thermostat, you should be getting hot water through the heater core to warm the inside of the vehicle. The engine coolant is there to keep the engine from melting down or from breaking metal parts and burnng off the oil. It just happens that the heated coolant is useful to warm the inside of the vehicle.

Coolant flows from the engine block into the through the coolant jacket?

Kind of. There are water jackets inside the engine block and usually the heads of a liquid-cooled engine Water (or coolant) will either flow from the block to the head to the radiator, or from the radiator through the head to the block (a reverse flow design). The latter is better because it cools the heads first and helps prevent detonation. It also reduces thermal shock to the engine block.
