Question about Chrysler Newport

1 Answer

Hello The coolant reads normal in my 383 while running unless I cruse down the highway, then navigate a few side streets to get home and turn off the engine. Once the engine is off the gauge climbs to very hot.If I restart the engine ( with some difficulty) the gauge will come down to normal after the coolant has started to circulate. Do you think this is caused by build up on the water side of the engine? Thanks Mark

    Hi Tim

    Yes I have used a radiator flush. The instructions read to flush all coolant and replace with water, add rad flush, then run and empty. refill with coolant.

    This made no differance. I think the only way might be to remove all the freeze plugs and clean out the gunk. What do you think.

It does sound like build-up alright, have you attempted to flush the radiator and put some new coolant in? Let me know what all you have tried, if anything and we will get this figured out.


Thanks

Tim

    Yes, definitely, if you've done the flush properly (and it sounds like
    you have) then try to remove the freeze plugs and cleaning it out. Not too many other things can cause this to my knowledge, let me know what you think / come up with.

    Thanks!

Fan comes on after I turn the car off its a 2001 Lincoln Navigator


Unless it stays on for a very long time (like over an hour), this is probably normal. What's happenning is the coolant sensor is still sensing hot coolant in the engine. (Assuming you're turning the engine off after it's been running a while.

need to check fuel pressure, not just listen for pump to run, also check reading on coolant temp sensor, but sounds like fuel pump /filter issue. just because you hear pump run doesnt mean its putting our right amount of pressure. also check for plugged catylic convertor

Bad thermostat


Hello,
To replace the thermostat in most vehicles yourself;
Remove the hose from the housing, then remove bolts from the housing and lift the housing off
to access the thermostat. Pay attention to witch side is up on the thermostat that you remove, the
new one will have to go in the same way. Also look at the temperature rating that is stamped into
the thermostat that you take out, and make sure the new one has the same temperature rating.
(failure to do so can cause false readings by some sensors, and may start triggering error codes)

Install new thermostat, right side up, put housing back on and bolt back down, hook hose back on
to the housing. Check the coolant level. Start the engine and let it run for 6 to 8 minutes to reach,
"normal operating temperature", and look for any leaking. before you turn the engine off turn you
heater wide open and listen for a click. Most of the time when a thermostat opens you can hear a
click and may hear the coolant flowing through the system. Shut the engine off, wait for it to cool
down and then check your coolant level one more time. ( do not fill all the way up, only fill to
FULL line on resrvior.)

If you want to double check the thermostat first;

How to test the thermostat in most vehicles;
Make sure the heater is off, start the engine and let it run for 6 to 8 minutes, ( this will allow the
engine to reach, " normal operating temperature "), from the inside of the vehicle turn the heater
temperature on high and turn the fan speed on high.
1. Listen very closely for a click sound from the engine, ( most thermostats make a click when
they open )
2. Watch your temperature guage, it should begin to lower as the coolant starts to circulate.
3. Usually within a few minutes the radiator fan will kick.

I hope this helps you.

My 2002 monte carlo is overheating on city streets but runs fine on the highway.


Hello June.
In behind the radiator there is an electric fan designed to come on when the coolant reaches a certain temperature.
At low speeds such as in traffic there is little airflow through the rad, but at highway speed it greatly increases the airflow.
So I suspect that the fan isn't working on your car.
This could be a bad fan motor, a bad fuse, a bad sensor or a wiring problem.
Also check that something hasn't fallen into the fan and jammed it up.

Thank you for using FixYa.

98 deville 32 valve North Star OVERHEATS after 33 miles of drive ?? does not overheat in town overheats out on highway and after slowing down- fans dont cool motor unless stop engine ,have changed radiator...


The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.
Also note that the cooling fans don't come on until the coolant temperature hits around 225 degrees.
During normal highway driving the fans will very rarely come on(if at all) due to constant air flow through the radiator.They will only usually come on in heavy traffic conditions on a hot day.
But......if you have the Air Con switched on, the fans will run all of the time.

97 saturn sl2 temp light flashing and low coolant light flashing what could be the problem ? coolant is full and the heat works.


If the temp gauge is reading normal, the lights are flashing, and the coolant level is full, the level sensor in the coolant bottle is the problem. I'm a service consultant for a Saturn dealer and I've run across this many times.

1990 Corolla Cooling system problems


Your temp gauge reads low on the highway, and one-half in the city?
You need to replace the thermostat. It is sticking open.
Driving at highway speeds, the blast of air that the car is cutting through enters the radiator, thusly cooling it, and the coolant inside the radiator... In town, with the lesser amount of air being forced into the radiator, (slower speeds), the coolant temperature rises. Replace the thermostat, and you will be OK.
