Question about 1998 Dodge Neon

1 Answer

Temp gauge pegging out, but engine isn't hot to the touch.

Engine appears to be cool (gauge pegs out before the car fully warms up), upper radiator hose doesn't appear to have much pressure. Electrical system has also been acting strange (lights staying on after closing the door, power locks intermittently failing, car died at stop light then started right back up). Recently replaced water pump which I believe may have been leaking all over the alternator. Car also has a new battery and timing belt. Temp gauge was acting strange prior to the timing belt being changed out. Any suggestions?

You could replace the sending unit to cross it off the list of possible problems.
You could check resistance cold and then with the engine at normal temp too. The gauge on the dash could be faulty too.

SOURCE: radiator cool, engine temp = 140

sounds like your radiator is clogged, it will bring problems to you soon, you need to flush it really good, i dont think you need to replace it but it sounds like a typical clogged radiator, have it flushed, it you cant ur gonna need to replace it soon, if you keep running that car it might lead you to a temp problem while runing and u might end up hurting your engine...
u also need to check if your thermostat is working properly. go on google and look for the procedure, ur gonna have to take it off and do a test with hot water and a thermometer and see if its working properly.
hope this helps.
have fun!

SOURCE: started with temp gauge going dead,then engine

Sounds like your voltage regulator is bad but you in addition you have a short somewhere causing these issues. Before you added the electrical stuff you were describing verbatim what I went through just before my timing belt broke. The oil would appear to be good but if I made a left hand turn a little too fast the oil light would come on. Now the good news, all of those repairs, assuming you do not have water in your oil (indicated by a creamy white or grey color when you remove the oil fill cap on the valve cover) can be made with the engine installed if you have two jack stands, two hydraulic jacks and a good metric socket and wrench set. (Preferably floor jack models) The alternator is difficult to reach but can most easily be removed from the bottom rear of the motor. You will also want to get a Haynes Repair Manual on your vehicle before starting. Auto Zone will lend you the special tool needed to remove the Harmonic Balance Pulley if you don't have one. The whole job takes about 6 hours if you take the time to review the steps and pay attention when your taking it apart.

My 1991 volvo740 bertone coupewater temp. gauge doesn"t move at all after the engine is warmed up. The upper hose is hot. The water in the resevoir is cool as is the bottom radiator hose. There was...


The thermostat is on top of the engine, just aft of the upper radiator hose. The temperature sensor (first one, closest to the front of the engine) is the one responsible for the coolant temperature gauge. It's an NTC with two resistors in it - one for the sensor gauge, one for the ignition computer. There is a second one for the Luftmassenmesser Hidtstraht system, bottom right side under the intake manifold.

If you have a drop of anti-boil on the water pump - it is coming from the weep hole and this is indicative of failure of the internal seals on the pump and it must be replaced.

There is a possibility that the thermostat is stuck closed, which can be easily verified in cool weather by cool air coming out of the vents at normal operating temperature. Check the heater core hoses - one should be warm.

Be careful when working on the cooling system - it can scald when hot! Always work on it with the engine cool to the touch and never put cold anti boil in a hot engine.

Checking the temp sensor is easy - remove the connector and place a 68 ohm resistor across both terminals (or one to ground if it is a single spade connector). The temp gauge should read approximately 3/4 across the scale. Don't short it to ground as this could destroy the sensitive coil inside the sensor. If no reading occurs, then the gauge or wiring is broken.

The temp guage pegs out on my 2005 uplander. I have changed the thermostat and flushed the radiator. The water pump seems fine and both radiator hoses get hot after it runs for a while. The fans kick on...


Having a blocked heater core will not make the engine over heat. You will just not get any of the heat from the fluid that would normally be pushed through the heater core because your core or cores are blocked (I think you have two cores if you have a rear heater.). The engine does not need your interior heater cores to keep cool. When you select "heat" on your console, either a valve opens up and allows fluid to move through the lines to your heater cores and or an air duct opens to the cores to blow air across them...


Did your heater work before your work?

Does the gauge stay pegged or does it fluctuate?


If your gauge now fluctuates after your work, it would indicate to me that there is air trapped in the engine or bubbles passing by. The air does not cool the engine block as well so the temp will rise quickly. It will then cool a bit as the coolant splashes by. If your gauge is staying hot and never moves, it could mean: you are missing a lot of coolant, trapped air near the temp sender, or your thermostat is not opening. A closed thermostat would make the gauge go all the way hot and stay hot. The thermostat can be checked with a pan of boiling water on the stove. When boiling, put the thermostat in the water and check to see if it opens. It is also important that the thermostat is installed in the correct direction. The temp sensor much be on the engine side. I am also assuming your pump shaft is not sheared and is still connected to the impeller and it is spinning as well. You can take your belt off and move it by hand to see if you feel any resistance. If you are sure the thermostat is opening and the pump circulating, I would then check and see if you have air in trapped in your system. I looked at my Uplander and noted a lot of hoses and metal pipes at a higher level than the filler neck of the radiator. Perhaps, when you filled your system back up from the radiator, that a lot of air got trapped in the upper part of the engine and the heater lines. I also saw that there were little brass valves near were the hoses connect near the pump and on the driver side. I would suggest running the engine and open and close the little brass check valve on the divers side to see if you have fluid or just air coming out. I wouldn

98 ford wind star running hot


Warm the engine up to operating temperature. Does the upper radiator hose get warm? If no, then cange the thermostat. If yes, then the thermostat is working fine. On the thermostat housing, there is a sensor. Some engines have 2 sensors. One goes to the computer and the other goes to the temp needle in the dash. Unplug the harness and put a jumper wire in the harness. Turn the key to on, and see if the temp needle goes up. Which ever harness causes the needle to go up, replace that sensor. Hope this helps.

Cooling fan problem


The electric fans on some vehicles dont stay on all the time. If the radiator is not burningyou then i would suspect the guage is bad. The engine would throw a code if the fan was not working properly, so im pretty sure that your fan is working properly. I hope that helps you out.

I am having trouble with my speedometer not working occasionally and now my seat belt light is coming on sometimes too. Is this the instrument panel cluster? Or something else? 1998 Dodge Neon. Backstory is as follows: -We take very good care of it and have one dedicated mechanic. -It has only had two owners; my parents and I. -We replaced the battery 2 months ago. -Mechanic checked to make sure the speedometer sensor was working. -We have had issues with the radio for years where it will randomly turn on and off, typically brought on by a stuffed trunk OR wet weather. -The speedometer works until we hit a bump and then the needle flies up and down or sometimes just stops working all together. -Mechanic has made mention of there being some Chrysler specific battery cable that is a smaller side cable and it is not in good condition. -Currently, my problem is that I can't find an old 1998 Dodge Neon in the salvage yard because yards are doing a lot of 2002 and newer vehicles and automatically crushing the others. The meat and potatoes of my question is what direction do I go in? And what of these symptoms ties to each other? And will adding new solder to the points on the panel fix it or is it something else? I'm trying to find least expensive to most expensive options and I'm rather handy but can't drop an engine or transmission or anything so keep this in mind. My handiness ends at resoldering the pins BUT I do have a mechanic I trust, but I fear that maybe I'm not combining symptoms properly. I have the money to repair an item I KNOW is wrong but not to chicken hunt around for problems.
