My car started running hot it’s 25degrees here so ididnt put water or coolant in it before I left.it started running hot then stop

Any help is helpful

My car has 8990000 miles.
My car has a manual transmission.

Experienced mechanics share their insights in answering this question :
Any of several components in the cooling system can be at fault. If the thermostat is stuck closed, coolant will not circulate to the radiator to be cooled. Even in 25 degree outside temperatures, the engine can overheat due to this. In rare occasions, the water pump impeller can separate internally from the pulley shaft. While the water pump may appear to be spinning on the outside, the impeller may not be moving at all on the inside. So just as with a stuck thermostat, coolant will not circulate. There can also be cracked head gasket causing the overheat as well as the intake manifold and/or gasket. Coolant does circulate through the intake manifold and are prone to failure.
If the coolant is not flushed on a regular basis – I am aware of GM recommendations with their Dex-Cool coolant but still recommend a coolant service every 2-3 years – as it ages, the coolant can become gel-like and corrosive. Also, mixing coolants (green coolant added to the red Dex-Cool) can create issues as they react badly to each other. and clog coolant passages. That can degrade the intake manifold or gasket.
Have a certified technician look into the overheating as soon as possible. Continued operation while overheating will damage the engine.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common reasons a Chevrolet Malibu is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
One common reason engines overheat while idling is a faulty or broken cooling system. This could include problems with the radiator, water pump, or fan belt. If any part of your car`s cooling system is not functioning properly, your engine may be at risk of overheating.
In general, it`s because something`s wrong within the cooling system and heat isn`t able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Cooling System Leak – This is probably the most common cause of an overheating engine. If any component in your cooling system–which includes your radiator, hoses, water pump, head gasket, and thermostat casket–starts to leak, you`re in trouble.
Most thermostat are between 175-190. That`s the temp range for the thermostat to open and cycle the coolant through, the cooling system. 6 people think this is helpful.
If you find that you`ve got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
An engine temperature over 220 degrees Fahrenheit is considered overheating in a car, though some cars are better at handling excessive heat than others. Engines run between 195 and 220 degrees Fahrenheit. If the car is operating within this range, it is not overheating.
Normal coolant temperature will be around 195 to 220 Fahrenheit (approx 90°C) and anything above or below this can start causing problems.
Sign 1: Temperature Gauge

While you might be tempted to think this reflects the outdoor temperature (some cars have this feature, too) the temperature gauge reflects how hot your engine is. When you see it rising towards the red temperature indicator, your engine is overheating.

How long can a car overheat before damage occurs? It only takes 30-60 seconds of overheating for permanent damage to infiltrate a vehicle. As soon as you notice signs of overheating, you need to act. Failure to do so might result in troubles like coolant leaks, damaged radiator caps, and a faulty cooling fan.
Start your car`s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
One of the first things you will notice is the temperature gauge is higher than normal. It may even start to fluctuate frequently. If you notice the gauge is hovering ¾ of the way from the top, then your thermostat is experiencing damage in the form of overheating. This can soon lead to your engine and car overheating.
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
When a water pump completely fails, it is no longer able to move coolant through the engine; this causes it to overheat. If you see steam, pull over immediately and call your mechanic for assistance — continuing to drive with an overheated engine can damage it to the point that it will need to be completely replaced.
If an engine “feels” cold, or “normal” but the dash gauge shows overheating, you could have a faulty temperature sensor and/or gauge. No cabin heat could be due to low coolant, blocked passages, faulty heater control valve and/or faulty blend door(s) in the dash ventilation network.
Not enough coolant: check the coolant level periodically. If the level is under the minimum level recommended, the engine may overheat because there is not enough coolant.

My car will be starting perfect and when the gas tank gets lower it will start having problems .
ANSWER : Based on the information you gave, it sounds like a possible fuel starvation issue, caused by a partially blocked, in-tank fuel filter or a crack in the fuel pump housing. The remedy would be to replace the fuel pump assembly and filter. The overheating may be caused by several things, including a stuck thermostat, faulty water pump, or even a cracked head gasket. I suggest having a certified technician, like one from YourMechanic, inspect the relevant systems to pinpoint the cause of your vehicle’s hard starting issue and overheating problem.

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.

Water was spilled in the trunk which soaked the car battery. Car won’t start now. Does water destroy a car battery?
ANSWER : Hi, thanks for writing in about the concern with the BMW 320i. If the battery was submerged in water then it’s completely possible for the battery to short out and die. Your friend will need to have the battery replaced. Also be sure to get all of the water out of the trunk. Have a certified technician, like one from YourMechanic, help you guys out if you need assistance with replacing the battery. Good luck.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

My car is running hot, what could be the problem?
ANSWER : There could be an issue with the cylinder head gaskets. Antifreeze can break down and become acidic if not replaced as normal maintenance. The head gasket material erodes and can cause engine compression to build up in the coolant system. This will prevent the flow of coolant which can create an overheating condition.

There is a test that can be done to check whether there is carbon monoxide in the coolant system; it involves special equipment.

I recommend having your overheating condition inspected, and perhaps have a block test performed.

My car ran hot yesterday and I let if cool and put water in it it cranks but it goes dead if I put water in it it stays on
ANSWER : Hi there. In general, when a car overheats it tends to cause excessive steam or hot coolant to spill in the engine compartment. This can cause electrical components to have problems with connections and have difficulty starting. The solution to these common problems is to first determine what is causing the overheating issue initially. You should have a professional mechanic come to your location to complete a car is is overheating inspection to begin the process of diagnosing these problems.

My f150 1997 runs hot after adding 50/50 coolant and water in the coolant resevoir wat is wrong
ANSWER : When the engine is cold, check to be sure that the radiator itself is full. If the level of coolant in the radiator level is too low, that can cause overheating. If you are adding coolant frequently, you have a leak and that leak can be identified in a cooling system leak diagnostic. Be sure not to drive the car if it is overheating because overheating can warp the cylinder head and/or engine block causing costly damage. The most common causes of overheating include low coolant level, a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt. Certain engine faults, such as a leaking head gasket, poor engine running condition, and exhaust blockages can also cause overheating. If you desire that the overheating problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an engine overheating diagnostic and the responding certified mechanic will get this resolved for you.
