When the engine oil was changed, the maintenance reminder was probably not re-set. Be sure that the level of engine oil is adequate as measured on the dipstick. Misfiring can cause engine and catalytic converter damage so be sure to...

Whining noise is often traced to the power steering pump (https://www.yourmechanic.com/services/power-steering-pump-replacement). Among the things to check are low fluid level in the pump reservoir, air in the fluid, degraded fluid, and inadequate tension on the pump drive belt. The pump...

Trouble Code P0121 (https://www.yourmechanic.com/article/p0121-obd-ii-trouble-code-tps-a-circuit-range-performance-problem-by-jay-safford) can set if there are faults in the wiring or terminal connections to the throttle/accelerator position sensor. Circuity integrity should be checked and the output of the sensor should be viewed on a scan tool to...

Hello. If you can hear movement from the motor but your wipers are not moving, then it is possible that the wiper linkage or bushings have broken or become damaged. Your vehicle uses a linkage mechanism with bushings that connects...

Water in the oil usually mean you have a blown head gasket. (https://www.yourmechanic.com/services/oil-pump-cover-gasket-replacement) This happens normally when the engine overheats and warps the head causing the water to leak into the oil passages of the head where the gasket meets...

Hi Bernie. Thanks for contacting us today. To be honest, the first thing I would suspect is that whoever is completing the installation is either forgetting a step or a few as being the reason that three reverse gears have...

The socket size is 5/8 for the spark plug replacement. (https://www.yourmechanic.com/services/spark-plugs-replacement) The spark plug wires should be inspected for dry cracks in the outer cover and also look for small white or black spots on the exterior of the wire...

It seems as if the transmission rebuild did not go as planned. I would recommend taking the vehicle to the place that rebuild the transmission initially, and then ask them to see if anything they did may have caused the...

Try another key if you have one. If the vehicle starts, then the first key is bad. The keys have a transponder in it that the ignition switch reads and allows the car to start. If you do have a...

The fact that all your windows are not working actually sort of narrows down possibilities. The power coming into your power window circuit is fused voltage, meaning it has a fuse to protect the wiring in case of a short...

The problem is with the internal shift solenoids not shifting the internal valve and you should first try to get transmission serviced and filter replaced. If after servicing the transmission and if it does not fix the problem then will...

Magnasteer was not an option on the 2011 Impala so what you are looking at is an irrelevant catalog entry (an error in the parts catalog). However, several different rack and pinion units were installed on the 2011 Impala and...

Hi Kemi. Thanks for contacting us tonight. What you're describing sounds a lot like either an inner transmission failure, damaged seal leak or perhaps a shift solenoid failure. It is also possible that you have debris trapped inside the hydraulic...

The gurgling sound you hear is likely coolant at work inside your radiator and heater core. The gurgling sound can be produced a few different ways. If the cooling system was not properly flushed the last time the coolant was...

This may be a sign of low transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car's computer activates a...

Hi, thanks for writing in. There are many things that could cause a misfire (https://www.yourmechanic.com/article/how-can-problems-with-the-ignition-system-cause-misfiring_2), such as faulty spark plugs (https://www.yourmechanic.com/article/symptoms-of-bad-or-failing-spark-plugs), a bad coil pack (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-ignition-coil), bad injectors (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fuel-injector), a faulty crank position sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-crankshaft-position-sensor) or something else. I would...

This vehicle may be leaking from the fuel pressure regulator; GM has issued a recall for the regulators not having a proper seal. The leaking you describe may, or may not be related to the recall. If the leak is...

The new transmission rebuild should not be slipping and for the amount of money it cost to get done i would recommend having the rebuilder test the computer for codes to the transmission shift solenoids and check fluid levels and...

If the car was not overheating prior to installing the new radiator, it is possible there was air trapped. There are air purge points (little bolts that are cross drilled) at high points in the system that are opened when...

Hi. This is a serious issue and should be repaired before driving the vehicle. Make sure that the car has enough coolant. first, you should never have to add coolant, so if it is low, then there is a leak...
