Why does my Mercedes Benz engine run hotter than normal?
It could be stuck such that the engine takes a long time or never actually reaches normal operating temp when the ambient air temperature is cold and the engine runs hotter than normal or even overheats when the air temperature is hot. Some normal fluctuation is normal. That’s why there are auxiliary electric cooling fans on radiators.
Why is my car stalling when reaching operating Temperatur?
Temperature gauges in vehicles are largely misunderstood. They will only give you accurate readings if they are submerged… Car getting no fire. Battery checked and is good. Started up, drove 4 miles to work. Tried to crank, nothing.
What’s the average temperature of a Mercedes Benz?
If it helps to find an average, my car is a ’99 c230K and it stays locked in at 80 unless it’s stuck in stop and go traffic on a very hot day but even then it barely budges above.
How does the air temperature affect the engine temperature?
The engine temperature will be more affected by the ambient air temperature. It could be stuck such that the engine takes a long time or never actually reaches normal operating temp when the ambient air temperature is cold and the engine runs hotter than normal or even overheats when the air temperature is hot.

When does a car stall at a stop sign?
This car’s engine intermittently stalls when it’s being slowed down at a stop sign or a turn. The stalling only occurs when the engine has reached operating temperature (15-20 min driving). It stalls very quietly with NO jerking, shaking, surging or choking.
How long does it take for car engine to start after stalling?
Most of the time after stalling the engine starts up right away, but sometimes it just cranks. After 30 min waiting or when engine get cooler, it starts every time. I am the only owner of this car. It’s been well maintained and cared for.
What happens when engine heats up to operating temp?
As the engine heats up the ring-cylinder mate becomes looser so that the engine will run smoother and easier…but if there is too much wear the combustion gases will begin to blow by the ring-cylinder surfaces and will cause each stroke to lose power.
Why does my engine temperature stay on cold?
Reasons Why Your Engine Temperature Gauge Stays on Cold. 1. Faulty Engine Coolant Temperature Sensor. 2. Faulty Gauge/Cluster. 3. Broken Wires to the Sensor Or to the Gauge. 4. Bad Thermostat.
What happens when you start a car in cold weather?
When you start the car, you will notice that it idles high for a period of time until the engine warms up. This is the enrichment cold start process. This is done with what is called a cold start injector which injects more fuel into the motor until the engine reaches a specific operating temperature.

What happens when engine gets up to temp?
Truck runs great cold when it gets up to temp the power decreases greatly. new fuel pump, new fuel filter, new air filter has been hooked up to two different computers and it’s showing no codes at all. New muffler and dual pipes,the old ones were bad. im at a loss and so are my mechanics
What causes an engine to stall in cold weather?
Engine stalling problems can be hard to find and are often sensor or temperature related. Engine stalling is more likely to occur during cold weather or when starting a cold engine. So, this kind of engine stalling problem often means the engine is not getting enough fuel and/or too much air.
What should the engine temperature be when a / C is on?
When the A/C is on, Engine Hot, ALL the Fans (Electric in front of the radiator) AND the Viscus Clutch fan behind the Rad. should at least be spinning if not spinning hard. If you turn on the A/C and the compressor is running I believe the electric fans should be running too.
When to change the coolant on a Mercedes Benz?
Click to expand… Mine stays at 87 Celsius all the time aswell, but it used to fluctuate before I changed the Thermostat, now its rock solid at 87 Celsius. Make sure yours has been changed, it should be changed when you flush the coolant every 2-3 years.
Where is the coolant temperature sensor located on a Mercedes Benz?
Replacing the coolant temperature sensor is a relatively easy job if you have a lot of patience. The sensor itself is located below the air pump and between the thermostat and coolant pump housing. The sensor is actually held in place by a small clip that sits in a channel created by both the thermostat on one side and coolant pump on the other.

What should the engine temperature be in a 4 cylinder car?
Most of the 4 cylinder cars in this section usually run pretty stable in temp under most conditions at just over 80c. Where can I find fuse for aux fan? those temps sound normal, mine ran steady 80 and under in the winter , now that its warmed up it goes up to 80-93 in the city when driving slow, on the highway its under 80 What’s the deal?
Is it normal for the engine temperature to fluctuate?
Some normal fluctuation is normal. That’s why there are auxiliary electric cooling fans on radiators. As long as the engine warms up to the thermostat temp rating within a few minutes and it doesn’t overheat, the thermostat is working as it’s supposed to.
What’s the normal coolant temperature of an engine?
If you are driving slowly or stopped idling the fans keep enough air moving through your radiator to keep your engine cool. Engine cooling fans may engage at one speed or multiple speeds and may kick on anywhere between 180 and 220 degrees.
What’s the normal operating temperature of a car?
While we don’t have your vehicle specific information, normal operating temperature for most vehicles can range between 190-220 degrees Fahrenheit. Thank you! -BDP
When does the car temperature gauge go up?
Your car temperature gauge goes up from 100 to 200 degrees F in 3 to 5 minutes after your car engine starts running, that is normal, because your car thermostat is close.
Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
What’s the normal temperature of a Mercedes SL500?
Could any SL500 owners just chip in with a 2nd opinion on the normality of this. My car is the same but even in average not really hot weather in traffic/stop start driving temp always does go up to about 100 degrees, no more, but will sit at about 85 degrees normally.
What’s the normal operating temperature of a Mercedes?
Having now driven My ’05 SL-600 thru the summer, I can say that the Temp Gauge in My car has NEVER been above 95C It runs at 90C all of the time! The ONLY time I have seen it move above 90C was when We got stuck in Boston traffic in August!!! 45min to go less than a mile!!!!
How often should I change the coolant in my Mercedes?
The M113 and M112 engines are designed to run at hotter temperatures as they are lean burn engines. Around town and under duress the norm is 100 deg C, on the highway at moderate temps and speeds temp should be 85 deg C:thumbsup: So no panic. Just ensure your coolant is changed every 3 years and only with Mercedes coolant.

What happens if you leave the thermostat open too long?
Left long enough, the thermostat will eventually stick at some position. If it sticks closed, the engine will overheat which can cause serious expensive damage. If it sticks wide open, the engine will not warm up to operating temperature and the heater won’t blow warm air. These effects are also affected by the ambient air temperature.
