20 Most Recent 2002 Chevrolet Impala Questions & Answers

On left hand side of the steering wheel you have a manual light switch that controls the dash lights for dim and brighter by turning the switch right or left, or you will have a wheel like switch next to it which could be the control that goes up to brighten and down to dim. Either type is a rheostat type switch, to lower the lights it decreases the current to brighten the lights the current is increased. if the contacts are worn or dirty it could interfere with the current control. Sometimes you can just go from left to right or up and down and clean the contacts to work. Other wise it time to replace the switch

Put in your search engine , Recalls on a 2002 Chevy Impala LS it will bring up quite a few good sites to pick from. They were more recalls then I could put down here.

Check the wiring to make sure it hasn't been damaged because of rodents or if it's been done wrong. Check the power and ground wires to the coil pack and make sure they're connected properly. If all of this is good check the relays and also the crankshaft sensor again. If all of this is good the likely cause for it not starting is the ICM (Ignition Control Module).

you engine has about 10 freeze plugs,there were created to be pushed out by ice if your antifreeze wasn't strong enough and froze inside the engine,that way the ice didn't crack the block when it expanded.
what causes freeze plugs to leak is the erosion affects from the antifreeze we use today,when they tell you to change your antifreeze every couple of years,the freeze plugs take another shot of strong antifreeze again,they just rust up on the inside of the engine until they get a rust hole in them

Middles, criss cross out to the corners. Finger tight using the socket bar only, then a bit tighter, and then final torque tight.

The engine does have to be raised. The bolts are not easy to get to until the engine is lifted and the engine mount is removed. I'm doing this job right now and the book time is around 5 hours.

Centre console

I would check the fuses first. Headlights are typically on a separate fuse then the parking lights. If the fuse is fine check and see if the Bulb is burnt out but it is rare for both lights to go out at the same time.

Here you go, depending upon the engine you have

Fuels, petrol or diesel, are known as hydrocarbon (hydrogen and carbon) fuels and so when burned in air (oxygen) one of the resulting products is a considerable amount of H2O or water. Mostly this is expelled through the exhaust as vapour but at certain times, such as when the air is cold and dry and the engine and exhaust system is cool, the vapor will condense and emerge as steam and water droplets. When a vehicle has lots of short journeys, the exhaust can become waterlogged where the silencers can retain a great deal of water and are likely to be spitting water droplets almost continuously. Often the sound at the tailpipe will be more harsh than usual. Some manufacturers have a small hole at the lowest point of a silencer to allow surplus water to drain away and sometimes a mechanic will drill a hole... Spitting water and emitting steam is often seen as a sign of a failing head gasket and the confusion is understandable as it is a natural function and could be a symptom of head gasket trouble but it is a symptom that should not warrant much attention in isolation - clearly if a failing head gasket is the source of water spitting from the tailpipe, the coolant level will be mysteriously falling without obvious leakage and often the engine will suffer a misfire on starting...

Here you go

Check the 10 amp PCM/BCM relay fuse inside the car. If that isn't it, please get back to me, and tell me again how you got it to start--how did you jump the relay?

Here are 2 links,one from Autozone that shows you what it look's like,the other on how to replace it.https://www.autozone.com/batteries-starting-and-charging/neutral-safety-switch/duralast-neutral-safety-switch/476559_0_0,here's the repair guide.https://itstillruns.com/replace-safety-switch-2002-impala-7890889.html

Have the OBD read as this will give you the codes for any problems, I would think it's ignition related but OBD will narrow down the fault

Probably a front wheel bearing is going bad

You have a bearing hub (sealed unit) To remove it, first remove the nut from the axle in the hub center, Remove caliper and brake rotor. You can access the hub attachment bolts through the holes in the wheel flange. You may need to put a chisel between the hub and knuckle (keep alternating sides) to break it free (they generally get pretty rusted in) use a good amount of solvent. Once it's out, clean the cavity and put a swipe of grease inside so new one goes in more easily. draw it tight evenly and replace remainder of what you removed. If it is extremely rusted you can rent a slide hammer to get it out but generally with a bit of patience they do break free.

I think you could use this manual method instead.. My nephew used it to repair my car and it's totally perfectly fine now. Here's the website he bought it from. www.reliable-store.com

If you've replaced the sensor, then you've got a connector or wiring harness issue.

A couple of things. Your thermostat could be stuck or you have air i your coolant system. Bleed your coolant system. If the coolant is low, you can also have that issue so check for a coolant leak. If you check your oil and it looks like chocolate milk, then you could have a blown head gasket. Check all of these first.
