Why does my car overheat only while driving?
The answer lies somewhere in the coolant system. More than likely, your thermostat is stuck. there are a few other things to check.1. Make sure your coolant levels are correct.2. Make sure the system is purged of any air that might be trapped (this would more than likely make the temps appear too cold though).3. Your water pump could be getting worn out and not pumping the coolant fast enough any more.In my experience, the thermostat has always stuck open making my vehicles run too cold, but I suppose it could also get stuck closed or partially open in which case it would cause the engine to get too hot during heavy engine use.Changing the thermostat is relatively easy for most cars and the part itself is very cheap (less than $10). It's worth changing first before paying hundreds to change the water pump.If you do have to change the water pump, it may be a good time to get your timing belt changed along with the timing belt tensioner pulleys and any oil seals that are behind the timing belt since they will have to be taken off to change the pump anyways.
What can I do if my car overheats?
if you are driving and your car overheats then safely bring it to halt. driving an overheated car will damage the engine gasket leading to its seizure.switch off engine and open the bonnet to dissipate heat quicly. DO NOT OPEN THE COOLANT/RADIATOR CAP. do not pour any liquid on engine bay to get temprature down quickly.best practise is to wait and let the temprature come down naturally.Once the temprature is down check the collant/water mixture in coolant tank and open the coolant tank cap (with your face away from the coolant expansion tank mouth to avoid steam burn) and add water.if you encounter overheating issue in a hilly or colder region then DO NOT add coolant while engine is hot otherwise it will freeze the mixture and damage the engine.To avoid overheating issues always ensure to periodically check the coolant and water mixture level and check for any leaks in piping. Always maintain your car regularly from authorised or skilled motir garages.
Battery dead on car and have overheating problem?
I was driving my car to work and first, the battery light came on. Then all of a sudden my power steering went out...I kept driving a couple miles, then my car starts to overheat...I pull over and the car is smoking. I open the radiator cap and water comes out. I start it up again no problem. I drive it another mile and the car is overheating again. There is no coolant in the collant tank. I put some in and the car drives fine for a few miles then the ABS light goes on. The temperature starts creeping up again and I pull over and open the hood and no smoke or the engine isnt hot...I keep driving and the gauge is on red for the tempertature. Slowly but surely the lights on my dashboard start getting dimmer and dimmer...My radio goes out...also my heater is not working...I lose acceleration on my car and car goes down more and more so I pull over...Then I hear a clunk clunk clunk sound. I thought my engine seized... The car wont even turn over and all power is dead. A bunch of water is spilled all over road. I get the car towed and the driver says it could be the water pump or the battery or alternator. We get to my house and jump start the battery and it starts right up. It dies after he takes off the jumper cables. He says we know it is not the engine and maybe the battery or alternator...I charged the battery for ten minutes and the car starts up again...but died after a few minutes of idle... I plan on taking it to the mechanic tomorrow...Why would all those happen all of a sudden. any help would be appreciated.. The car is a 2000 chevy malibu 6 cylinder too
My car is overheating and there is no heat inside? What could be the problem?
the main reason for this overheating to occur is because of leakage in your coolant or the coolant that is being used is not reaching or is not being circulated properly.it takes various other components for working of your cooling system. Overheating can be caused by factors other than low coolant level (thermostat stuck closed, blocked radiator, malfunctioning fan or failed water pump). If all these conditions are present then you better get your car checked by mechanic.
HELP PLZ! My car is overheating while idle and going slowly?
It's not the thermostat, which doesn't care at all whether you are idling or not. In my entire life I have only once seen a thermostat cause overheating, and that was in a car that had been driving down the highway when it suddenly overheated. They are often suspected but almost never responsible. There are two possible reasons for a car to overheat while idling but be okay while driving - air flow or water flow. Air flow (fans) is the far more common problem but from your description that is all working right. The radiator is supposed to be colder near the outlet because the radiator is cooling the coolant down. And that other fan is the A/C condenser fan, so it is working right also. Actually, other than the basic overheating problem everything you describe is completely normal for the conditions. That leaves us looking at water flow trouble. Water flow is not a common problem, but if there is a large bubble caught in the cooling system that will do it. I'm not familiar with the Mitsubishi, but many cooling systems have procedures for bleeding trapped air. It is also possible that the radiator is nearly plugged so the coolant doesn't circulate enough at idle; this will happen if tap water is added to the cooling system in large enough amount. The hard water minerals precipitate out in the radiator as the liquid cools and the small tubes become blocked. If that is true the heater will put out lots of heat as the engine overheats, while if the water pump has disintegrated (rare but not unknown) the heater will put out cold air when the engine overheats. The test for a plugged radiator is a flow test. Shops can do it for about half an hour labor or you can do it yourself by removing the radiator hoses and sticking a garden hose in the upper hose fitting of the radiator. If the radiator is okay it will pass all the water the hose can put out. The last radiator I changed (for a friend) was so blocked I could hardly blow air through it. Radiator blocking typically shows up at higher speeds but if the pump is not trying hard it can happen at idle.That 25 minute lag makes me a bit suspicious of the radiator.
What causes a car to overheat?
My car just hit 100,000 miles but is in good shape. Yesterday it overheated. I had been running the car on and off all day. Could that be the cause? I was not even using the air conditioner. I added two quarts of oil and anti freeze and it still started to overheat this morning...Please help.
What would cause my car to overheat while driving but not while idling?
Your Right Foot.Thats the short answer.The longer answer is a clogged raditor fins with too many bugs stuck between the fins.Something, is preventing the heat from the engine from dissipating through the radiator.The rad consumes 10x the volume of the engine intake system to cool the engine down to 205F or 90C.Next simplest fix is to check the level of coolant when cold, and the strength of the glycol water mix.The glycol aids in the reduction of the internal pressure, within the cooling system, and it is possible in closed loop systems to have an ‘air bubble’ inside the upper radiator hose, when a low amount is in the block.The ‘THermostat’ is a special motor, that speins around as the temperture of the fluid increases. If the Thermostat is stuck closed, it never will open up to release the heat through the radiator , as the hot fluid gets sucked from the water pump back into the block.If you have a high level of calcium or minerals in your local tap water, a simple coffee maker test, with vinnegar and water can flush out the accumulated calcium out of the tubes.So, after performing a cleaning, then re-filling with the proper mix of the correct for your vehicle, anti-freeze coolnt, should give you a point of reference to begin with a clean radiator,The replcement of the fluid, is not that expensive, and the flush with an acid flush (vinegar is an acid).It does not involve tearing apart the radiator or the engine to get at a water pump or a thermostat.You have not spoken on how old the whole system is, and the last place you took it for an oil change.the oil-change quick lube people sometimes put the wrong fluid into a car as a top up, then you wind up with jello in the rdiator and the coolant galleys inside the block.Gently drive the vehicle to a trusted independant shop, and let them diagnose what is wrong. Tell them the last time you had the coolant checked for the strength, and make sure you get an estimate before any parts are replaced.
What could be causing a car to overheat and push the coolant out of the reservoir?
This is like asking ‘how long is a piece of string?’There are a myriad of reasons, failed water pump, blocked radiator, head gasket failure … all of these could do that.You need to identify what’s happening before it starts blowing water out the reservoir - is the water circulating? Are there traces of oil in the water? Have you done a HGF test - checking for exhaust emissions in the coolant?Could also depend on the car - one manufacturer that I worked with had a problem of overheating on tickover, but if you increased the revs, it increased the efficiency of the water pump and cooled the vehicle.
