Step 1: First off, open your car bonnet to reveal your car engine. Step 2: Then look for the car engine thermostat. Go over to your car and put on the ignition, so your car engine warms up. Step 3: Take out your infra-red thermometer, aim the thermometer on the engine thermostat to take the temperature readings.
The temperature gauge in your vehicle is designed to measure the temperature of your engine`s coolant. This gauge will tell you if your engine`s coolant is cold, normal, or overheating. It is an important dial that is located on the dashboard of your vehicle.
The ambient temperature sensor (switch) is located either behind the front grille or in the front bumper. Its only job is to monitor air temperature (which it does through increasing/decreasing resistance in response to temperature fluctuations).
That`s why your car`s dashboard includes an engine temperature gauge and/or a warning light to help you monitor the engine`s temperature and notify you when the temperature is out of the safe range.
The temperature gauge, most often located on your dashboard in your vehicle, is intended to show the temperature of your engine`s coolant. This indicator will let you know if your engine`s coolant is cold, normal, or overheating.
A red (occasionally yellow on some vehicles) engine temperature warning light that stays on or comes on while driving means there`s a coolant fault or your engine is overheating and requires immediate attention.
This sensor is Sensor is located on the thermostat housing and measures the coolant temperature.
Most vehicles have their thermistors on the front of the car, located behind the grill. This location makes the instrument`s measurements sensitive to reradiated heat from the road surface.
You can find the ambient air temperature sensor at the front of the engine bay. Usually, this sensor is located behind the grille but is in front of the radiator and radiator support.

An ambient temperature sensor is a sensor used to measure the temperature of the air that surrounds a component (the ambient temperature).
Most cars these days have 2 sensors: one inside and one outside. The sensor that measures outside temperature is typically up behind the bumper, which is near the hot asphalt and the engine. That`s why it reads a little higher that what the temperature actually is outside.
Dashboards differ on how they display the temperature of your engine coolant. Some cars include a gauge that measures coolant temperature and varies from cold (C) to hot (H), while others feature a thermometer that will illuminate red if your engine is dangerously hot.
The ECT sensor may also control the temperature gauge on your dash, though in some vehicles, that is done instead by the engine coolant sending unit, otherwise known as a temperature switch.
If the coolant warning light becomes illuminated on your dashboard as you`re driving along, it`s a certain sign that your engine is overheating. In order for your car to work, a series of explosions are created in the combustion chamber.
If you`ve ever glanced down at your dashboard in confusion at a little blue light upon starting your vehicle, we`re here to tell you exactly what that little light is. It`s your coolant temperature light, and its job is to indicate the temperature of your engine.
The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine`s coolant.
The coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant. The sensor works by measuring the temperature that`s being given off by the thermostat and/or the coolant itself.
What is the difference between temperature and ambient temperature? Ambient temperature is the average temperature of an environment and can be any temperature. Room temperature refers specifically to the temperature range in which the average person feels comfortable in.
As opposed to room temperature, which is a range of air temperatures that most people prefer in indoor settings, ambient temperature is specifically the temperature of the air in any particular place as measured by a thermometer.
Cars use a device called a thermistor to measure temperature, by measuring the changes in electrical current when heat is added or removed. Most thermistors are located behind the grille on the front of the car, meaning they`re fairly close to the road surface, which can affect the measurements.
You may be surprised to know that most cars are equipped with a thermostat as part of the engine`s cooling system. While your home`s thermostat is used to monitor the interior of your home, your car`s thermostat is used to regulate the temperature of the engine to help the engine stay cool.
The coolant level warning light will show up on your dashboard when your car is running low on coolant. Most of the time, this will occur due to a leak that is causing the coolant to escape from the engine.

No coolant in the reservoir. Seen low coolant message. I added 2 quarts of 50/50 coolant. Still getting the message. How much coolant doe it need?
ANSWER : Hi there. For the coolant light to go out, you would need to have the coolant between the low line and the full line for the light to go out. If the coolant is low and keeps on being low, then look for any signs of coolant leaks. You may have to use a coolant pressure tester to pressurize the reservoir to allow the leak to be found.

If you need further assistance with the coolant being low and the warning light being on, then seek out a professional, such as one from Your Mechanic, to help you.

Car temperature keeps going up and coolant level drops.
ANSWER : Hi there. The milky engine oil is caused when the coolant from the cooling system gets into the engine oil. There are two ways that the coolant can mix with the oil on your vehicle. The first way is through the intake manifold as the gasket may crack causing the coolant to drain into the valley area making the coolant mix with the engine oil. However, the engine will not overheat quickly when this happens. The second way for the coolant to mix with the engine oil is through a burned head gasket. To verify that the head gasket is burned, get a block tester from your local parts store and set up the tool by putting the blue chemical in the tube and putting on the plunger on the end. Then remove the reservoir cap or radiator cap (take precautions of the coolant) and start the engine. Take the tool and place it over the inlet area to the reservoir or radiator. When steam starts to form in the area, use the plunger and suck in the steam into the tool. If there is any hydro carbons (raw unburnt fuel) in the cooling system, then the blue chemical will turn to a yellow or greenish color. If the color changes, the head gasket is burned and needs replaced. If the chemical does not change color, then the head gasket is good and there could be a leak on the intake gasket. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your engine overheating issue.

Over heating coolant not siphoning back into coolant over flow tank
ANSWER : Hey there:

It’s common for many mechanics to make the mistake of mis-diagnosing the cause of an overheating situation; especially when they assume it’s a thermostat issue. The problem could be caused by a blockage in the coolant tubes running from the radiator to the overflow tank and back to the radiator. However, it also may be due to air trapped in the coolant lines. I think a good idea would be to contact a different ASE certified mechanic, such as one from YourMechanic, and have them complete a coolant flush, which should remove any blockages in the coolant tubes and may solve your problem.

Coolant temperature too high – 2011 Audi A7 Quatro
ANSWER : It sounds like the engine thermostat, a device that reduces coolant flow until the engine has reached it’s operating temperature, is not opening. This prevents hot coolant from getting to the the radiator where it is cooled. If the dealer is unresponsive, I would have a professional mechanic, like a certified technician from YourMechanic, check your vehicle for failing cooling system components.

Possible coolant in my oil but no oil in the coolant. Use about 1 l of coolant per 100km.
ANSWER : Check the transmission fluid. If all testing eliminates the head gasket, cracked cylinder head, etc, it may be a cracked radiator.Transmission fluid is sent forward to the radiator to be cooled. Ir runs into what is typically called the "side tanks" of the radiator. So the transmission fluid and coolant are both flowing through the radiator and kept apart just as the engine oil and coolant are kept apart in the engine by the head gasket, coolant and oil passages, etc. If the tank in the radiator is cracked internally, transmission fluid may actually be forced into the coolant as transmission fluid is under higher pressure than the coolant. Short of a cracked head gasket, cylinder head, or engine block, it’s really the only other source of any type of oil getting into the coolant unless the vehicle is equipped with an engine oil cooler as well.

Engine coolant temperature problem
ANSWER : You may have a persistent overheating issue due to a clogged radiator, blown head gasket, worn out water pump, etc. This should be checked out by a professional mechanic immediately to avoid being stranded or causing further damage. A professional, like one from YourMechanic, can determine the source of the problem and make needed repairs.

Scirocco engine coolant light comes on in cold temperatures
ANSWER : Hi there:

Sometimes this issues is caused by a faulty or loose electrical harness to the radiator temperature sensor on the VW. It will send a faulty error code and cause the symptoms you’re experiencing. However, it could be a problem with the sensor itself that needs to be replaced. The fuel economy issue shouldn’t be related; however, it’s common for fuel economy to reduce in winter or late fall, as that’s when they swap out fuels from summer to winter blends. Winter blends are not as refined as summer; which can cause increased consumption. The best way to know for certain is to have a mobile mechanic complete a check engine light inspection so they can determine if there is a real issue you need to resolve.
