If you can't see where its coming from, it may be a cracked head, or a bas headgasket. Also, when you add water to the coolant tank, it doesn't immediately go into the radiator. After the car sits a while, the radiator starts to cool, creating a vacuum. Water/coolant is then pulled into the radiator from the coolant tank.
What else can I help you with?
Why is my 1998 Subaru out back overheating?
The 2.5 liter H4 engine has a major problem with getting blown head gaskets. Mine had this problem at only 50,000 miles. The coolant then backs up inside the container and your engine overheats drastically. If you don't get it fixed quickly you can blow your engine.
What is the job of the cooling fan and heat sink?
They're used to help keep the processor on the motherboard inside the Central Processing Unit (CPU) from overheating. Both are necessary: the fan actually protects all the devices inside the CPU from overheating, while the heat sink is used especially for the processor as it gets overheated quickly.
Why is my 2001 Mitsubishi spyder overheating even though the fluid is good and the fans are working?
A 2001 Mitsubishi Spyder will experience overheating even though the fluid is good and the fans are working if the thermostat is stuck. A stuck thermostat will prevent coolant from circulating and will quickly overheat the engine.
Can anyone give any clues why BMW 318i 1998 temp gauze is hitting red very quickly in terms of distance driven and why it is overheating so quickly?
It's possible that it's the thermostat or a blocked radiator, but if it's blowing the coolant before the engine gets hot it could be the headgasket. BMW's are notorious for having a problem with warping heads easily if the engines overheat.
How long would it take for a head gasket to blow if you do not drive a vehicle when it overheats?
Here are several answers and opinions from FAQ Farmers: * If it overheated one time, it could have blown a head gasket. * It depends why it overheated. If it's low on coolant, it doesn't take long at all for the head to overheat and warp. That would blow the gaskets fairly quickly. If it overheated by overworking (going up a mountain, etc), but the pump is fine and it's filled with coolant, shutting it off is the worst thing you can do. In that case it's best to pull over to the side and let it idle. That will continue to circulate coolant throughout the system and it will run the electric radiator fans. If you shut it off, all the heat rises and warps the heads.
Why does 97 Pontiac Sunfire over heat or red line?
There are several possible reasons for overheating. Could be that your water pump is dieing. You can often hear it rattle when it's spinning, or you might be able to feel a lot of play in the pulley. It could also be a fan problem. The fan motor has died so the fan never "fans". Or it could be a temperature sensor failure and the fan is not being told to turn on. Basically, if you have an overheating problem, it means that coolant is not being circulated through the engine block, or the coolant is not EFFICIENTLY being circulated, and/or that the cooling system, IE the radiator and/or the fan is not operating correctly. Do you have coolant in the reservoir? If not, or if it's low, top it off with a 50/50 mix of antifreeze and water. If you add coolant and it goes away quickly, you have a leak in a hose or at the water pump. Are any of the hoses collapsed? As you can see, I'm rambling here. That's because it's early and I haven't had enough coffee, and because overheating problems can be a bear to troubleshoot. If I were you, I'd check the obvious. Failing finding a problem, I'd get the car to my mechanic. Let us know how you do, OK? FriPilot
What causes a radiator to boil over in a minute?
A radiator may boil over in a minute due to low coolant levels, a malfunctioning thermostat, a clogged radiator, or a faulty water pump. When coolant cannot circulate properly or regulate the engine temperature, it can quickly lead to overheating and boiling over.
Will a engine overheat without a thermostat?
Yes, an engine can overheat without a thermostat. The thermostat regulates the flow of coolant to maintain optimal operating temperature; without it, the coolant may not circulate properly, leading to inefficient cooling. Additionally, the engine may not reach its ideal temperature quickly, which can also cause overheating under certain conditions. Overall, the absence of a thermostat disrupts the cooling system's balance, increasing the risk of overheating.
Can you run your car without a water cap?
Not for very long - the cap seals the cooling system and allows it to pressurise. The thermal efficiency of internal combustion engines increases with higher internal temperatures, the coolant (normally a mix of water and ethylene glycol) is kept at higher-than-atmospheric pressure to increase its boiling point. Thus the coolant is able to remain liquid at higher temperatures. With no cap the coolant can vaporise and escape, quickly resulting in an overheating engine. Severe engine damage can be caused by overheating, by overloading or system defect, when the coolant is evaporated to a level below the water pump
What does it mean when you take off the radiator cap and there is no thermostat in it and it throws water out?
If there is no thermostat in the radiator, the coolant can flow too quickly through the system and fail to properly regulate the temperature. This can cause the coolant to boil over and be expelled from the radiator. Installing a thermostat can help control the flow of coolant and prevent overheating.
Why would a 1998 Plymouth Neon get hot as soon as you start down the road but not when sitting still?
When you move, you put more load on the motor. Check the water level in the radiator. Check the fan to see if it comes on. look for water leaks and signs of water leaks(rusty lines)AnswerThere is a bulletin on 1998 Neon-concerning this ongoing problem. The best solution is to replace the thermostat,seal and a new radiator cap. I did this two years ago and the vehicle never overheated. Also, make sure the radiator fan is working! AnswerAssuming by Hot you mean Overheating, The Fan System can be ruled out (Fan cools when there's no motion). Thermostat is not the problem. Check coolant for debris - Stop Leak or similar have been thorns in my side because they tend to block off a coolant passage in the block. In these cases, the car would idle and never overheat, but would start overheating as soon as the vehicle was driven. It's possible the coolant is low, but doubtful - Keep in mind, the only -real- difference between cooling system heat at idle and while driving is the Automatic Transmission (If equipt) fluid (Which gets hot very quickly) is being cooled in the bottom of the radiator.
Does the car airconditioning use coolant quickly?
Only if it's leaking.
