Question about 1998 Dodge Stratus

1 Answer

Coolant temp stays low

I have the 2.4L 16 valve motor in my Stratus and had to have the head gasket replaced. Since doing that the coolant temp never goes past the second mark on the gauge, not even close to the half way mark. And now that winter is setting in I just don't get the heat into the cabin like I use to because of the low coolant temp. Any ideas as to why the coolant temp stays so low?

    Very good idea. I thought of that and went to the auto parts store and got a new thermostat. Although I didn't think about checking the temp. rating of the one that was sold to me. That did seem to bring the temp up a bit, but not significantly.

I believe when they replaced head gasket they installed too cool of a thermostat in it. need to replace thermostat with proper one should probably have a 195 degree one in it

    IF it runs too cool the pcm will set a code for coolant below threshold. is check engine light coming on? you may have a restricted heater core. might wanna try back flushing core. the thermostat regulates temperaure. feel your heater hoses and see if one is cooler than other

low coolant, thermostat, or head gasket

Engine runs rough if it warms up won't start dtc codes p0118 and p0113 just did head gasket and replaced exhaust manifold all new gaskets new plugs wires and coolant engine timing marks are all c


P0113 Intake Air Temperature Circuit High Input


Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

P0118 - The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.
Potential Symptoms

Symptoms of a P0118 could include:

  • Very poor fuel economyicon1.png
  • A no start condition
  • Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
  • Illumination of MIL
Causes

A code P0118 may mean that one or more of the following has happened:

  • A bad connection at the sensor
  • An open in the ground circuit between the ECT sensor and the PCM
  • A short in the voltage feed between the sensor and the PCM
  • A bad PCM (less likely)
  • A bad temperature sensor (shorted internally)

How do you fix a blown head gasket for mazda mx3? And what would cause it to idle low and overheat to where it shuts off.


check your water pump and ects (engine coolant temp sensor) and just replace head
gasket the other thing to check for low idle is under the throttle body is a erg valve it it what lets in more or les air depending on the temp of the engine it has coolant lines going to it and if blocked can not work of this help

I have a 1995 EF FALCON. I have a constant battle with the cooling system. Loses coolant. I replace parts that fix the problem and not long after it is somethingh else. I have replace hoses, thermostsat,...


Your vehicle is what...16 years old? Parts do not last forever. I can't see changing the pump twice unless the old one was defective. There is no reason to replace a pump unless it leaks or is noisy. OK, now the low coolant light is on. Is the coolant low? Is the engine running hot? Low coolant sensors have been notorious for failing. If the level is good and it's not overheating you can either remove the indicator and replace it or just disconnect it and routinely check all your fluids (you should be doing that anyhow) once a week. Cars did not have or need that sensor for many years. Gas stations used to check fluids when they actually could afford to have people pump your gas for you. It only takes a few minutes and isn't a difficult task to check everything over now and then.
If you have found the level to be low, re-fill it and check again for leaks. White smoke from exhaust can mean a bad cylinder head gasket as can oil in the coolant or coolant in the engine oil. I've found some vehicles (including one Jeep I own) that will not keep the overflow full but never overheats or has problems. Some head gaskets deteriorate and begin to seep coolant on the outside of the engine. That kind of leak often evaporates on the side of the block and never drips on the ground. Check around the head/block parting line. If you find a crusty white or greenish residue there, run the engine and watch that spot. If it gets damp there, it's leaking. As long as it continues to run well and the temp stays normal, everything should be OK.

Heater problem


Ok, some clues, good. When the jeep has been driven for 10minutes, it should be at operating temperature. What does the temp. gauge indicate at that time? Is it on the low (cold) side, in the middle (normal) or near the hot end of the temp. gauge? Let me know the answer to the above, also check to coolant level and let me know what you find. If the coolant level is low, it can result in the engine running hot, and result in no heat. When the level is low, it won't circulate coolant through the heater core, which means you won't have heat. So let me know about the engine temp, and the coolant level, this is the easiest and simplest possibility of why you don't have heat. If this isn't the problem, do not rate my answer until I can help further after I get the above info from you.

Coolant sensor


refill and bleed the cooling system.  The water from your overflowing radiator may be the cause of you engine problems....dry of the motor.
