The engine fan in my 2003 MC SS doesn't seem to be working and the car is starting to overheat. The other fan, which I think is the A/C fan seems to be working okay. I know nothing about cars and before I take this to a mechanic. I do not want to go somewhere and get totally ripped off. So it would be nice if I appear to know what I am talking about... when I take it to the mechanic.
View 2 RepliesA month or so ago my engine light came on with the message "engine power is reduced". well i had it checked out, the code from the engine light suggested a bad throttle body. I then replaced the throttle body myself. (unplugged the throttle body sensor, unscrewed the four bolt holding it on, replaced with new throttle body, and reattached cord to new sensor that was attached to the new throttle body) i then re-learned the idle speed through chevys process on their website. The engine light disappeared and everything was a okay for about a week and a half. then it started doing the same thing again. (engine light came on message appeared, obvious reduction in power from the throttle) It is continuing to get worse and sometimes it will shut off my engine display the message "starting disabled service throttle".
I have been shutting the car off ( if it wasn't already off) and wiggling the wires leading to the sensor attached to the throttle body. i'd then close the hood and start the car and it would act normal (engine light still on) with no reduction in power until the next time (which was usually about 30 driving min later give or take) recently a new symptom popped up when i am going uphill or giving it the beans it'll display the usual engine pwer reduced message and sometimes shut off the car. not only that but if it gives me the message and shuts off if i dont wiggle the wires or something of that nature when i start it the whole car shutters while the rpms go up and down. so did i just get bad luck and buy a faulty throttle body ( i bought i t brand new from o'riellys or however you spell that) .
My 2006 Monte Carlo has been making a strange 'tweet' sound. I only notice it when the car is off. It's just a single 'tweet', a minute or so will pass, then it does it again. What could this be? I'm worried it's something expensive.
View 4 RepliesI have a 1999 Monte Carlo 3.1 motor with 180,000 miles. I changed both fan relays, the temperature sensor (and the connector), and the main cooling fan motor. The temp gauge works but fan will still not work..I swapped the relay between the ignition relay and the fan relay to make sure they worked (they all do )..I checked continuity between the sensor and the relay and continuity between the relay and the fan motor everything seems to be getting through the wiring. only thing is when I disconnect the sensor the car wont start. what could be keeping the fans from working?? Is there a separate sensor that operates the fans??
View 14 RepliesRecently purchased this Monte Carlo SS with a bad engine. Picked up a really good engine and it sounds great. Backed the car out of the garage, and when I shifted into drive, the car would hardly move. It felt like it was starting out in high gear. Had code P1860 (Trans converter clutch) set. Car has 150K on it. Suspected bad trans. Just had the trans rebuilt by AAMCO to the tune of $1100.00. Still have the exact same problem. The car will go in reverse just fine, but it won't hardly move forward. The old engine pushed a lot of antifreeze and oil through the exhaust. When I started the new engine, it smoked like a smoke stack for about 20 minutes, but then quit smoking. What am I missing? The trans is full of oil, and all connections are fine.
The Monte Carlo is a 2000, not a 2001.
I took my Monte in for the annual Missouri Safety Inspection. Note: I had no known problems with my 2003 Monte SS 117K Miles. After the inspection, which passed, I was informed of a variety of problems: Intake Manifold Gasket Replacement, Valve Cover Gasket w/Intake replacement, Thermostat w/Intake Removal, Fuel Injector O-Rings w/Intake Removal.
My question is should I have all of this done? It's not cheap..roughly 1000 bucks. I know very little about this and I don't want to just tell my mechanic to do it without some research. Are these common problems with Monte's of this age/mileage and just part of the cost of owning this car. I am the original owner and have avoiding costly repairs/maintenance..it's been a great car.
I was riding my 1985 Monte Carlo SS down I-20 and the engine abruptly shut-off. The radio and all of the lights were still operating. I pulled over to the service lane and waited an hour for a tow truck. While waiting, I was constantly checking to see if the car would start. After an hour, the car started again and I went on my way. I left the car parked for about 5 hours and when I went to start it, the car started right up. After making it about a mile down the road, the engine shut-off again in the turning lane of a busy intersection. I wouldn't start again after that.
I had the car towed 30 miles to my home and left it sitting. I just changed the alternator, spark plugs, spark plug wires and battery, the car still won't start. I used all high-end parts, no cheap stuff. The battery meter is reading low, even with the new battery.
The has an aftermarket UNGO alarm system in it, which is "spidered" into the ignition system. This prohibits power to everything except the lights if the key isn't in the ignition.
This miss feels like the engine is stopping not just missing but jerking the car for one cylinder. If I just barely hold speed it is minimized or if I step on it it will stop so I'm pretty sure it's not ignition wires or coils etc.. I would suspect pre-ignition but it's been going on a long time ( a year at least) while I've been half fast trying to figure it out so if it's pre-ignition then this is a hell of a strong engine. I have suspected a slightly sticky injector because of the working fine at more throttle. 1997 3.4DOHC Monte Carlo
View 3 RepliesThe air coming out the right front vents is cold; but, the air coming out the left front vents (driver's side) is warm. Sliding left ac slider switch up and down did no good. Considered fuse, but both left and right AC controls run through same fuse. Suspect bad motor for left side plenum duct, or bad connection, or faulty vacuum at motor (if motor is vacuum actuated). Considering removing dash cover to see if I can find the motor, but not sure how to remove dash cover, or even if that's the way to find the motor.
View 7 RepliesI have a 95 Monte Carlo LS it has 53,000 miles and When I go to give it gas it hesitates and the rpm goes down and then I let off the gas and do it slowly and its fine. Why this is happening all of a sudden. And my check engine light is on.

View 1 Replies1997 Monte Carlo, 3.1 liter, 3rd engine, I have oil in the coolant and it uses 1 qt of oil every 3,00 miles. No smoke from the exhaust. What is causing this???
View 5 RepliesTurned the key on my 2002 MC SS, V6, 3.8L, and the Intake Manifold exploded.
Intake Manifold Exploding on a GM V6, 3.8L? It sounded like a 12ga shotgun. Fortunately no one was looking into the engine compartment at the time as they likely would have been killed given the amount of shrapnel from this explosion. Note that the explosion was powerful enough to blow off the oil cap, which is screwed on with very thick threads.
The vehicle was at my mechanics at time and in his forty years he's not seen an intake manifold explode save for those residing on Top Fuel or Funny Cars.
I recently (about a year ago) got a 2000 Monte Carlo, great car, runs good, just one issue. Lately, when I accelerate it shakes in the front end, I let off the gas, the shaking stops, some days are worse than others. Some people have told me its the CVS, or the axle, or the motor mounts. Is this common with a 2000.
View 1 Repliesmy 2002 monte carlo sat for a few weeks and when i started it the radio doesn't work nor do i get the sound with the key being left in the ignition. fuses seem ok.
View 6 RepliesThe car takes off from a stop as it should. However, it shifts hard from 2nd to 3rd gear and that's when it stumbles and doesn't want to accelerate. It'll go if you press pedal at least halfway down. It runs great other than that. It only has 60k.
View 4 RepliesI think I've joined the ranks of the no overdrive in our Monte club. Bought the car last summer, 184K on the odometer. Previous owner was original owner. Said trans was always strong. Took the car for a spin Saturday. Previously, no OD issues. It's cold out. Pulled up to a light to get out onto main road. Right turn on red. accelerated normally, but noticed a long hold in 1st before shifting into second. Never saw it before, so was paying attention at the next light, which was right away. Accelerated again, and again a long hesitation going from 1st to second.
Next light is right away again. Light turns green, car shifts normally and I drive it about 10 miles. No issues. I paid particular attention to it going into overdrive, and it did. Arrive a junk yard. Got the part I wanted. Spent about an hour in there. Came back out and started home. Car shifted ok, but did not want to go into overdrive. Thought to myself, well, maybe it's cold. Drove some more. Nope. Never wants to go to overdrive anymore. It does shift from 1-2-3-4 ok. I've heard about the stripped spline in the output shaft, but I was wondering if there is another controller somewhere inside, or outside of the trans that could be causing this issue. When I am in OD and in 4 gear and driving at about 50 MPH and I shift it to D, I feel it shift into 3rd. I plan on getting it diagnosed, but was wondering what you all are thinking.
Replaced intake gaskets , used the rocker arm tool to take out push rods, put it all back together now, the check engine light came on and its telling me my timing is off.

View 2 Replies04 monte with oem radio and CD player.
Wife said she was driving down the road and it all just went quite. The radio lights and power is on and the cd works taken cd in and out. Only problem no sound whatsever with radio or cd.
I have a problem on the blower motor and i think its something besides the blower motor going out it works fine most of the time but occasionally it does not come on when this occurs I noticed that the cruise light is flashing in the dash and when this is occurring you can push the on/off switch in the steering wheel and the light does nothing. Now whenever the blower motor works properly everything with the cruise functions properly no light in the dash and when turning on/off switch works properly also no noise coming from blower motor ( bearing ) sounds fine. would a bad BCM cause this or am i looking in wrong direction ???
