Repair Questions and Answers

Question: 1995 Plymouth Neon mileage:
125,000. This is a brake-related question. I recently
noticed that both front rims seem to heat up under
normal driving conditions. I've had the front caliper
assemblies professionally replaced, which has reduced,
but not eliminated, the heating. I guess my question
would be this: Is it normal for front disc brakes to
heat up enough to make the rims almost too hot to touch
? (There are no noticeable signs of a pad dragging or
anything of that nature--and it does seem to occur
equally on both sides.)
Answer: During normal driving the
brakes and wheels do get hot. Make sure that your brakes
are not dragging. If you have aftermarket rims, they may
be blocking the air-flow which keep the brakes from
cooling properly.
Question: 1996 Plymouth Neon
Highline mileage: 85,000. O.K. I read through the
questions you have answered in the past and I found a
situation much like mine. The oil leak happened around
40,000 miles. Small oil leak that was resting on top of
the transmission, then onto the ground. I went to 3
places and they told me they think it's either the head
gasket or the main seal. I have no traces of oil in my
coolant system, and one shop replaced an O-ring off of
my oil sensor thinking it might be that, but to no
avail. Where do you think the leak might be coming from?
And just how many other '96 Neon owners are having oil
leak problems with limited miles? I know I shouldn't
have been driving my car with the leak present at all.
But with limited money (see car in question) I couldn't
afford to have it taken care of. And my warranty was
less then adequate!
Answer: There is a very good chance
your problem is the head gasket. Neon has had problems
with head gaskets.
Question:
1997 Plymouth Neon 4 Cylinder SOHC mileage:
81,000. When I started my car today the lights are
dim, but my car still started. On the drive to work,
when I was stopped at a light the idle was rough and my
battery light came on. I still got to work,
luckily. However, when I went to start it again
after work it took a few seconds for the radio to come
on. However, my car would not start and my lights
were extremely dim. When I got a jump I got
home fine, but my lights flickered all the way home even
when I pressed on the gas. Now it will not start
without a jump. What is my problem PLEASE HELP.
Thanks
Answer:
From what you tell us, it sounds like you may be having
trouble with your charging system. Have your
battery load tested and check the alternator output for
voltage and amperage.
Question:
1997 Plymouth Neon Highline 2.0 SOHC mileage: 48,235.
Right after (my) break-in (aprox. 2200 miles) period I
took the car back to the dealer because I thought the
engine was a little noisy. They told me that the
sounds the engine made were normal. I really
was not sure but I do know that different engines make
different noises. So, I let it ride. A short
time ago, the engine started making a VERY LOUD noise
intermittently. It only does it below 20 degrees
f. and randomly intermittently. When I first start
the car it is fine for approximately 6 to 10 seconds,
then it makes a noise like a REALLY LOOSE connecting rod
bearing for approximately 5 to 10 seconds, then it goes
away and may not reoccur for days. Anybody have
any ideas? P.s. I am a motorcycle mechanic so I am
somewhat familiar with the internal workings of the
engine, but make no mistake about it I DEFINATLY am NOT
a car mechanic.
Answer:
We think that a hydraulic lifter may be hanging up
causing your noise.
Question:
1997 Plymouth Neon. My "check engine" light has
been on for the past week. I took it to the dealer and
they told me it was because of my "upstream oxygen
sensor". What / where is this, and is it something
I can change myself? Is this the same thing
as the "oxygen sensor" in my exhaust manifold?
Answer: Yes, it is in the exhaust
manifold. It is easy to change when the engine is
cold.
Question:
1999 Plymouth Neon mileage: 25,000. Gas mileage has
suddenly dropped from 250 to 125 or so per tank.
Some power loss when pull off from a stop but other than
that runs well. Dealer ship mechanic says it
checks out ok. Sounds ok.
Answer: Check the catalytic converter to
make sure it is not “plugged” or restricted. Your
car is equipped with a computer controlled engine
management system. An independent auto service
center can scan your computer for fault or error codes.
The information should pinpoint the malfunctioning
components.
Question:
1995 Plymouth Neon 2.0 mileage: 185,000. I had a
timing belt go on this car and I was wondering if there
was any chance of the engine not being ruined. I
do realize the 2.0 4cyl SOHC is an interference engine
but I was wondering if there was any chance of the
valves surviving such an ordeal. I could not get a
strait answer out of the service dept at the local dodge
dealership. They obviously wanted me to bring it
in.
Answer: One way
to tell for sure is to replace the timing belt and check
compression.
