Check the floor on the pass side. It is probablly wet and the heater core is leaking. This is a pretty big job and if you want to change it your self, get a manual from the parts store or AUTOBOOKSONLINE.COM

AnswerHate to tell you, but changing the heater core may get rid of the antifreeze smell from the vents, but it won't solve the overheating problem. You need a new fan clutch (if you have rear wheel drive). If you have front wheel drive, you probably need a new electric cooling fan or cooling fan motor.

It's pretty simple to understand. When you stop, the cooling fan comes on to pull more air through the radiator. When you start moving again, your speed forces air through.

It's a pretty simple fix, and for most cars should cost less than $150. You can get by with less than $75 if you do it yourself (unless you own a BMW like me--my fan clutch is $225).

Answer

I have the same issue, and the fans were not working. My pigtail was loose connected to the sensor, so it was just a bad electrical connection. However, now that my fans are working, its overheating dramatically!

Why does my car overheat when it is in neutral?

Because the engine is still running while in neutral. Your problem is probably your radiator or lack of antifreeze. Antifreeze serves as what it's name implies and as as a coolant. Additionally since the automobile is not moving forward the radiator is not receiving ventilation provided by the incoming air.


How does coolant work?

Engine coolant is what I'm assuming you are talking about. Engine coolant is a mix of water and etholyn glycol (antifreeze). It pulls heat away from your engine block that builds up from the friction of moving parts. The coolant mix allows the coolant to get cold to a point and not freeze because of the etholyn glycol. It is also not good to put straight antifreeze into your engine because antifreeze does not have as much cooling potential as water antifreeze mix. Also if you have just antifreeze in your engine the antifreeze will boil at a much lower temperature than a mix of aproxamalty 50/50.


What would cause car temperature to rise when stopped but drop when moving or when engine is revved?

The thermostat is failing.


Why does an engine need oil?

Oil is required to lubricate all the moving parts, without oil these parts would overheat with excessive friction and seize within minutes, the engine would be ruined.


Will the car run without the oil pump?

It will run but not for very long. No oil pump means no oil will be moving throughout the engine to lubricate and cool the engine. The engine will overheat, bearings & rings will wear and in a short amount of time the engine will lock up and self destruct.


Why do cars overheat when not moving?

There is insufficient airflow for cooling


What will happen if you don't have oil?

In an automobile engine with no oil it will self destruct in short order. It will start to overheat immediately after starting and all moving parts will start to experience sever wear. In a few minutes the engine will seize.


What is the purpose of the fan or alternator belt?

Any belt in a car assists in moving all parts within the engine to work in providing power and cooling to vehicle. The alternator provides power to the battery and the fan cools the radiator so the engine will not overheat.


Why did settlers stop moving west?

Settlers stopped moving west because they no longer could. Settlers stopped moving west when they ran out of land to move onto.


Motor leaks antifreeze out of front of oil pan motor knocks?

If you have antifreeze coming out of your oil pan you're in trouble. Knock comes from poorly combusting gas/air mixture in the cylinders. Engines need oil to lubricate the pistons moving in the cylinders and the crankshaft, gears and mechanisms controlling the valves. If you have antifreeze coming out of your oil pan, that probably means you have a cracked engine block because antifreeze circulates in the cooling system, which is supposed to be entirely separate from the oil circulating. More likely is that the antifreeze is leaking out of one of the pipes or hoses, especially at connecting points, and dribbling down the side of the engine to the oil pan at the bottom of the engine, and it just looks like it has come out there. If the engine loudly knocks all the time it may be a thrown rod.


What are the Effects of driving car with no oil?

the engine will run hot and eventually it will blow on younot true.. if you have no oil in your engine it will not last long enough to overheat... the force of the pistons moving will cause so much friction, add that to the lack of lubrication and your engine will seize up and never work again...


How do you know when your water pump on your 1995 Chevy Lumina is bad?

One way is: with a cold engine, take off the radiator cap, start the engine and let it run to operating temp, and look into the radiator to see if you see any coolant flowing usually from one side of the radiator to the other. If you look in the radiator and the coolant is not moving, then your water pump is probably gone, and don't overheat your engine. Without coolant flowing through the engine you cna overheat the engien and cause severe damage.


Why lubricant oil use in as a engine oil?

Oil is used to lubricate the engine and help keep it cool. Without oil the engine would overheat and all the moving parts rubbing together would soon wear so bad that the engine would seize and basically self destruct in a very short amount of time.


What happens when you put petrol in a 2 stroke lawnmower?

The engine will overheat & seize due to lack of oil. A 2 stroke needs a fuel oil mix to lubricate it's moving parts.


Does there will be the same day after 2 months if the earth stopped moving on its axis?

If the Eath stopped moving on its axis the day would be as long as a year.

What is the energy of a stopped car?

A vehicle has energy only when it's moving. When it's stopped, no energy is being created or used.If the engine is still running, then it certainly is producing energy to move the pistons, turn the crankshaft, etc. But that doesn't affect the vehicle's energy unless the vehicle is moving.

Where is the cooling fan sensor on a 1989 323 Mazda and how do I check it engine heats up when I am stopped fine when moving.?

The thermo fan sensor is on the thermostat housing, right below the distributer.

What does it mean when the left side of your radiator was smoking and it damaged the radiator cap when you took it off there was a lot of coolant in the radiator?

Your water pump might be broken or your thermostat might need to be replaced. You obviously don't have a leak so somehow the fluid isn't moving through the engine. If the thermostat is broken it will not let fluid into the engine and then the engine will overheat and the radiator will release smoke.


What is the cause of getting high temperature of engine when you are moving slow and stop go movement?

More than likely if your vehicle is only getting hot at slow speeds or at a complete stop but not when the vehicle is traveling at a nomal speed, is becUse your radiator fan has stopped working. If your fan stops working there is no air traveling though the radiator when you are moving slowly or stopped to cool the coolant.
