2012 Chevy Cruze eco

I have a 2012 Chevy Cruze Eco 1.4L turbo charged engine with a manual transmission. My problems began 2 weeks ago when while driving the 30 miles to work I randomly got an “engine power reduced” message and the car wouldn’t accelerate over 15 mph. I attempted different gears, releasing then re-engaging the accelerator but all yielded the same result. After calling my coworker to swoop in, and save the day by picking me up, I pulled the vehicle into a parking lot and killed the engine. While gathering my necessary belongings it occurred to me that this could have been cause by an electrical short or failure which might self resolve if I recranked it so I did. Everything was normal and I was able to continue the commute to work without incident. A few days later during the same commute I caught a slight whiff of oil burning and upon arriving at work noticed smoke coming from under the hood. Opening the hood would reveal that the oil cap had been blown off and oil shot all over the engine. Keep in mind it has been 3 months since my last oil change but I suppose it’s possible that they did not reattach the cap correctly. Added oil and replaced the cap which I luckily found caught below the engine. Later that evening upon starting the car all the gauge needles shot all the way to the right, then back again and the car died. Several attempts to restart it yielded a no crank no start condition. As I began to pull out the jump box my son said mom try it one more time which I did and it cranked right up. This exact situation occurred randomly 3-4 more times over the next 2 days. Friday morning it did this again. After waiting a few minutes the car started and began driving normally. Then the engine power reduced flashed up on the screen and i immediately killed the car where it was and waited. I restarted it again and the anti theft warning flashed up on the screen. Once again I killed the car, restarted it, and a new traction control warning was displayed. I killed the car again and was able to restart it and drive 5 miles to the gas station without further incident. Attempting to leave the station proved more difficult beginning with the car dying immediately after start and not cranking for longer than 5 minutes. Then it started and died while I was reversing out of the space and since it wouldn’t crank I opted to push it backwards out of the way. After waiting a while I was finally able to start and drive the vehicle but as I turned out of the gas station “service power steering” warning came on the screen and I had no power steering

All the way to my street where I finally killed it and restarted it with no issue. I dropped my son off and proceeded to head to work but within 12 miles I got the engine temp too high A/C off warning (fyi a/c wasn’t even on) I immediately pulled off and killed the engine before the guard reached H. When I opened the hood I discovered that water was everywhere and the overflow hose going to the overflow bottle has been blown off and was sitting on top of the engine along with the 2 o-rings. I left the car, got a ride to work and bought a thermostat after work to put on it. After replacing Taft the car weak cranks but won’t kick off

I just bought the car in March and have had no issues with it. It does have 165k miles though and I’ve been wanting to take it in for regular maintenance/ check up but haven’t been able to afford to do so. Regular oil changes only and I replaced the water flow outlet and that overflow hose which blew off last month when it overheated and was Spraying water out a crack in the side. I’m wondering if this could be the anti theft system or the ignition coil pack.

Re: 2006 equinox rocker arm specs in ft pounds

tighten the rocker arm bolts to 24 lb ft (32 N.m)


Re: Installing new cylinder heads on 2001 Chevrolet Impala 3.4 Vin code E. Are they just bolt down and go?

the torque specs have a revision. the revision says to replace with new head bolts. (common becuase the bolts are torque to yield) Torque the new head bolts to 60 Nm (44 ftlb) Once they are all torqued to spec, using a torque angle meter, rotate the bolts an additional 95 degrees.



since you are asking about torque specs I thought I might mention that the intake and exhaust push rods are different lengths. Make sure you put them in the correct order or you could damage the engine you put so much work into.

Car dies when put in gear

2007 trailblazer low beams not working fuses ck ok

2007 trailblazer SS day time lights & low beam not working checked & replaced bulbs ,fuses ok ? still no high beams lights work turn signals work is tere a relay some were bad !


Re: van

If you have a no crank and no lights verify that you have battery voltage ay the battery terminals. If you have 12.5 volts at the two posts of the battery then you need to track down the open circuit. Could be the negative or the positive side.



If the battery is dead then charge the battery and look for a draw on the battery. Something is draining the battery down.


Camaro 1994 3.4 24x sensor

Hello, i have 1994 camaro v6. It starts and then after couple or more seconds (or if i press gas pedal) shuts off. Obd1 diagnostic shows 36 code for 24x crank sensor. I tried to test it with multimeter and it will not show any signs of life. All wires are good, sensor gets 12v ground and signal wire to pcm is okay also. I changed pcm and nothing changed. Changed crank sensor and nothing. Then i tried to put a3144 hall efect sensor but still no change. If you have any clue whats wrong please help!


Re: Head gasket??????

if it looks like a pressure hose that's leaking what does it go to on each end? Can you see oil squirting out? Does it just have oil on the hose and it's dripping off the hose?



If the leak is coming from a hose what makes you think of a head gasket problem?


Re: Serpentine belt

make, model and engine size would be needed to view the belt routing.



I have replaced some serpentine belts to bypass the AC compressor when the compressor went bad and they didn't want to fix it but needed to drive the car but Never tried to bypass the power steering before. Why would you want to not have power steering?



Most power steering vehicles (that the power steering isn't working) are harder to drive than manual steering cars.



Newer cars tie in the braking to the steering system. Traction control will activate during normal driving and cornering. Power steering not working may affect handling more than just steering.


Re: 2000 malibu camshaft position sensor location

Here is a picture of the engine


Re: ABS code c1233 impala

C1233 is set when the brake computer sees that the right front speed sensor is open or shorted. If you have the scanner that you read the code with, can it graph the sensors? What would be good is if you can graph the wheel speed sensors and see what data they show. Most likely, you won't have any right front signal. It could be a bad wheel bearing. (sensor is built into the bearing) It could be a break in the wheel speed sensor wiring. It's not uncommon for the harness that goes to the sensor to break where it is always bending when the vehicle goes over bumps and when turning.



If you see that you have no sensor signal for the R/F sensor, I would jack up the front of the car and unplug the wheel speed sensor wiring and use a volt meter in the sensor. Connect to the two prongs that go to the sensor and turn the wheel hub. you should see the rotation by spikes in voltage. The faster you turn the more you see the meter move. Check the right and left side. see if they both look the same when you turn them. If the left side looks normal (it should since you don't have a code for the left) does it look like the right side? If you don't have a signal from the right side then you probably need to replace the wheel bearing. If you replace the bearing I would go ahead and replace the wire harness for that sensor too. Since your there anyways.



If the right sensor looks good and matches the left side when you turn the hub, then plug the sensors back in and look at the scanner while the hub turns. Does it match what you saw when you measured the sensors? If you don't get the same signal at the computer that you got at the sensor then most likely you have a broken wire in the wire harness. The harness that connects to the wheel speed sensor is a wire that plugs into the sensor just goes from the sensor to the main harness. It doesn't go all the way to the computer. So it's not too bad to change. Just make sure that you run it the exact same as the old one comes out. This way it won't rub or chafe in other components.



Jacking up the vehicle: make sure the parking brake is on. Make sure you have safe jack stands under the vehicle. Be safe. Do not test the sensors with the engine running. Testing at the sensors is with the engine off key off. Testing the signal to the computer is with the key on and the engine off.



let me know what you find out.

Chevy Lumina Coolant leak

My 98 Chevy Lumina 3.1 L is leaking coolant tour the firewall area. What is a possible cause other than the intake gasket


Re: Monte Carlo SS Knocking Overheated

the overheat tabs for gasoline motors usually melt at 260 degrees F.They don't come on new factory motors but many rebuilders and/or used motor sellers will install them to protect themselves against warranty claims. Most companies put at least 4 tabs on a motor. on the head and on the side of the block. They should look like a small button glued to the motor.


trailblazer No ac temp low

I have a 2008 Chevy trailblazer. I have read of the forms where temperature gauge goes to zero and the AC shuts off. I replaced the temperature sensor which was no fun. Same issue exists. Does anyone know where I go from here.


No reverse, acceleration issue

I have a 1998 Chevy Cavalier that I purchased about a month and a half almost 2 months ago the car has had a total of three owners I am the third the second was my brother the car has 152 something thousand miles and my brother did sell it to me cheap because I needed a car to get me to and from work and it does not have reverse. When you try to put the car in Reverse you can hear it try to engage you can hear it click and you can feel it try to engage but when you try to put your foot on the gas it does not move however if you are on a slight incline and even in my driveway that is completely flat it will roll back on its own when it is in neutral it will not roll back at all in my driveway like it does in reverse. When my brother still had the car he had someone look at it the guy he had look at it does not know anything I've read multiple reviews about him and he has cheated multiple people out of his their money that he has ruined their Motors there Transmissions rip them off he's just a bad guy all the way around he told my brother that there was metal shavings in the transmission fluid and that the bands in the transmission were bad and that even if the fluid and the filter were changed in the transmission that it would completely ruin the transmission and it would no longer run at all currently up until Saturday the car ran perfectly fine in Drive as of Saturday it started acting weird it started having issues with accelerating and then as of Sunday it overheated on me and on Monday I replace the thermostat after replacing the thermostat it overheated again we bled the line and got all the air out and also ran a toggle switch because the radiator fan was not kicking on the water pump on the car is new I know the car is not getting hot but the temperature gauge is going crazy it goes from running at regular temperature too cold as if the car was just started even when it's been running for 30 minutes or longer it has a really hard time accelerating it makes a really loud whining sound that started as of Saturday we realize that there is a hole and a crack in the reservoir for the power steering pump reservoir I do intend on getting a new reservoir on Friday I'm just not understanding what could be causing these new issues along with the issues with the reverse as well when I check the transmission fluid it does smell burnt and if it is a brown color instead of the normal red color. As for the accelerating issues when that did happen on Sunday it was as if the car would overheat as the RPMs would get higher the higher the RPM the hotter the car would get I did get it to the side of the road and pulled over before it got too hot so I know for sure I did not blow a head gasket this is the six Cavalier I've owned so I know them like the back of my hand but this one has me dumbfounded! I personally have had it looked at by four different mechanics I've had one person tell me that it's the transmission is completely bad I've had one person tell me that it just needs new fluid and a new filter I've had one tell me it's the solenoid and I've had one tell me that it is the pump that is inside the transmission. I've reached out to multiple transmission shops in my area and none of them will look at it because they State because it is such an old car and it does not have reverse that I'm better off just selling the car to a junkyard and going and getting a newer car but I do not have the money to do that nor the credit. And I personally like my car and you not want to go in debt for someone else's headache I would rather fix what I have even if it comes down to having to replace the transmission I just don't want to get ripped off!
