Question about 2002 Dodge Intrepid

Open Question

My temperature gauge is showing hotter than normal...but no overheating as of yet. I have plenty of coolant in the system. Do I have a water pump problem forming or perhaps a bad thermostat? Car runs fine otherwise.

SOURCE: coolant temperature sensor location for 1999 Dodge Durango

The sensor is right next to the heater hose outlet on the front passenger side of intake manifold. It is very small with an oval shaped connector going to it. I have the same engine.

SOURCE: Engine runs hot on 2001 Stratus R/T 3.0L V6

Hello, as previously suggested by my collegue it appears you have an air lock. Have you tried parking the vehicle on level ground, from cold with radiator cap off start the car and leave it idling. Make sure the fluid/coolant levels are o.k. and let the engine reach operating temp. Keep some warm water handy and watch/listen the water/coolant system (Keep a safe/sensible distance from radiator) hopefully after a while the system will bubble and boil up let it settle for a few seconds and then top up with very warm water do this until it hopefully stops belching out of radiator. Replace cap and hopefully top and bottom hoses will be warm. Oh! nearly forgot keep all heater controls on hot with blower on full..(Inside the vehicle)
Finally I'm not joshing but is the thermostat in the right way round and functioning correctly? to test drop it in some boiling water it should open almost immeadiatly.
sorry for the epic but I'm here to help and hopefully save you time and money.
Good luck and a Happy New Year to you and your family!

SOURCE: temperature gauge is getting hot have changed thermostat

Hello.

The air release valve is a black plastic screw by the coolant refill cap, if you unscrew this slightly after you've driven the car, it will release any air if it has any (be careful of the steam). If this solves your problem you're very lucky. I think it's most likely your water pump needs reeplacing. I would suggest getting this solved asap as there is a very real danger you can get your engine head damaged if the temp keeps going beyond the normal.

SOURCE: 1996 Mercury Sable Wagon Overheating

sometimes the radiator is just too plugged to respond to flushing. (happens a lot with a marginal radiator because when flushing, the solvent simply goes around the plugged area, and cannot build up enough force to break it free). From what you have written, this may be the case. Is the electric fan coming on and off at the right times? if not this also can give you similar problems. You have done the right things but may not have gotten the desired result. Hope this info helps you a bit.
good luck

SOURCE: How common is a stuck thermostat or overheating.

A stuck thermostat is fairly common (especially if it's original on your truck). If the thermostat is stuck, its common for antifreeze to back up into the reservoir tank. I

A bad water pump will normally overheat at lower speeds. If you notice the engine temp comes down when you turn on the heater, it's most likely the water pump.
Best of luck.

My engine in my 97 lumina is so hot you can't touch it but car runs normal and it's not over heating


If you are not losing coolant and the temp gauge reads normal, it sounds like everything is OK. Many parts of an engine will be too hot to touch.

If still wanting to make sure, you could renew the temperature sensor unit as well.

Ford Freestar 2006 Engine is temperature is normal but , the dashboard gauge is showing high temperature. Which parts need to be replaced to bring back the dashboard gauge to normal.


How do you think the engine temperature is normal if the gauge is telling you the engine is overheated?

make sure the engine is filled with coolant both at the reservoir and at the filler cap on the engine itself. Usually this cap has the thermostat below it. If they are full, try burping the system by squeezing the radiator hoses with a sealed system and the engine hot. Wear gloves!

if that doesn't fix it, buy a new thermostat. They are cheap and easy to install.

If if that doesn't fix it then you are looking at emptying the coolant system and back flushing it after adding something like CLR or Radiator Flush.

Might also be a fault with the pump or a slipping belt?

Mitsubishi shogun 1998 model 2.8 over heating no leeks water is blowing back into the overflow bottle when hot


How are you sure it is overheating? Temp gauge? Most likely are stuck thermostat, bad fan thermostat switch, bad fan. bad head gasket. Coolant going into overflow when hot is how that system is suppose to work. As it cools, fluid is drawn back into radiator. It it is not really overheating, bad radiator cap can allow coolant into reservoir more than normal.

How to tell if car is actually overheating


If you have a temperature gauge it should stay at or just below the middle when the vehicle is fully warmed up. Slight (very slight) fluctuation on the gauge is normal. This is all dependant upon having proper flow of coolant through your coolant system. If, for instance, your water pump is broken, there is no flow of fluid acros the temperature sensor, thereby giving you a false reading. The temperature sensors in the car need the fluid to flow across the sensor to give a true reading. When the car is fully warmed up, squeeze the top radiator hose hard a few times. You should feel moderate resistance and then you should feel the surge of coolant back through the hose as you release it. If you dont, your water pump may have quit working or you have a sizeable blockage in your coolant system.,

Over heating


When your temperature gauge reaches "H' it may too late to prevent a major breakdown. Knowing the symptoms of an overheated car and how they occur may be the difference between being inconvenienced and incapacitated.
Identification:---Other than a low oil level or low oil pressure light, there is not a more significant part of a car's instrumentation than a rising temperature gauge or a glowing "Hot" light. These lights are really the only confirmation a driver has that his car is really overheating. It is the identification of the symptoms of an overheating car that enable the motorist to avert a badly damaged engine. Overheating is always a traumatic event for a car's engine, which makes the early identification of the symptom an important addition to the informed motorist's tool kit.
Stuck Thermostat:--The car's thermostat is a valve that controls coolant flow from the engine block to the radiator. When the engine is cold the thermostat remains closed so that the coolant can reach operating temperature quicker and also provide heat to the passenger's compartment. The thermostat has a spring on it that moves depending on coolant temperature causing the thermostat to open. Sometimes the thermostat fails to open thus restricting coolant flow to the radiator where it would be cooled down. This condition is often the cause of overheating. The symptoms of this cause would be a rising temperature gauge and possibly the loss of heat inside the car.
Restricted Radiator:---A car's radiator will have thousands of gallons of coolant passing through in its lifetime. Along with the coolant comes particulate matter in the form of corrosion breaking loose from various parts of the car's cooling system. These contaminates collect in the tubes of the radiator reducing its efficiency. Extensive "plugging" in the radiator will cause the car to overheat. The symptom of this condition would be a rising temperature gauge which goes up when you accelerate.
Coolant Loss:--A car's cooling system is a closed loop system. You are not supposed to lose coolant. Sufficient coolant loss will cause the engine to run hot because engine is heating less coolant to higher temperatures. The symptom of overheating induced by coolant loss would be a pool of coolant on the pavement when the leak is external. Steam under the hood as the lost coolant hits hot parts of the engine, or a rising temperature gauge in the case of a undetectable engine related leak. Of course, the gauge would also go up if the leaks were not detected. Deteriorated Water Pump:--Cars use a belt driven pump to push the water and coolant mixture through the cooling system. This part is called the water pump. Rarely the impeller that draws the coolant through the pump will rust away making it impossible to push any through the system. If this occurs the temperature gauge will climb and coolant will boil over in the radiator. Inoperable Fan:----Most cooling fans are electrically driven. Some are driven by fan belts. If a belt breaks or the electric supply to the fan is interrupted overheating may result. Electric fans are tuned on thermostatically when needed. When the car runs at idle for extended periods or the weather is extremely hot, a failed fan will cause overheating otherwise it serves as a standby assist to the rest of the cooling system. In stress conditions an inoperable fan will cause the temperature gauge to rise. This will help. Thanks please keep updated.please please do rate the solution positively .thank you for using fixya

Temperature control


The radiator cap is at the radiator where you refill the radiator with coolant. Unless it is leaking and you hear a hiss. It may not have anything wrong.Neither will the water pump.If the water pump is bad. It has a small hole that will make it start leaking .Check the engine for leaks at the intake or the water pump.You will know where it is leaking. When the thermostat was removed and hopefully replaced , did you bleed the system ? The system has to be bled to remove air pockets. Or the engine will overheat again. Also check that the radiator fan or fans is turning on . If not you may need to replace the temperature control sensor.(TPS)

Rapidly rising temperature in 2000 Olds Silhouette


Could easliy be your water pump. The coolant in the radiator isn't being forced through the engine by the water pump causing the coolant to be cool and motor overheating. A thermostat can also cause this problem, but I belive it's the water pump.

Overheating


Hi,

If it were a defective water pump, the increase in temperature would not go back down to "mid range (getting cooler)", so most likely it is not.

It is most likely a sticking thermostat as that is basically its purpose, to restrict the coolant flow and allow the engine to reach operating temperature thereafter grant free flow of the coolant. It would seem that there is considerable delay in its opening and therefore the temperature rises above the normal operating temperature.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
