Its behind the harmonic balancer. There is one bolt that holds it on, it may be covered up with build up, but there is one bolt and one plug on it.
If you look at your new one it could help.

93 Chevy lumina van , no spark ,tunes over nice ,3.8 engine


Almost always it's the crank sensor on a 3.8.They fail so often,I recommend changing the crank sensor at every tune up.
Otherwise the 3.8 is a great engine.

I need the easiest possible directions to replace the coolant temperature sensor in my 1999 Chevy Lumina ltz 3.8 v6 car please.


The coolant sensor temperature is usually found just beneath the cylinder head, on the engine block.

You just disconnect the 1-2 wires and then undo it with a wrench.
The sensor will look like one of these:

Just be aware .. you may have TWO such sensors on your vehicle.

One sensor (usually with 3-4 electrical pins) is near the thermostat and works in conjunction with other sensors to regulate fuel/air according to engine temperature.

The other type of sensor is in the block near the cylinder head. It sends a signal to the temperature gauge on your dashboard ONLY. If your temp gauge constantly reads too hot or too cold .. this one is the culprit.25939754-r0ibht2u2t2rhetbyfvb2pry-5-0.jpg
If it's a running fault .. speed .. rough running .. fuel. It may look like this:

When i step on the gas my car dies out, and then after starting it 3 or 4 times it wont start.


I also have a 91 chevy lumina with the same problem, have replaced the coil packs, throttle sensor, crank sensor and new spark-plugs and still the same problem. Also how many wires connect the the crank sensor as I have two wires that are discconected. Any help will be will better than replacing parts that I don't need to. I am disabled with MS and my car is my legs!!

Thanks Diane

Where is the camshaft position sensor located-99 Chevy Lumina 3.1


It's held down by one bolt right above the timing chain cover. It's next to the head that's facing toward the front of the car.
