there are 3 O2 sensors on the 4.3 Vortec V6 Blazer ( I have a 99 as well) 1 is on each exhaust downpipe forward of the catalytic converter, the 3rd is just aft of the converter.
no such thing
The crankshaft sensor on a 1999 Chevy Blazer is located on the bottom of the engine, near the oil filter. It connects to the vehicle's computer and constantly updates it on the crankshaft's position.
If it had a bad O2 sensor the "check engine" would be illuminated and a code would be set indicating which sensor is at fault. You probably have other problems causing that backfire to occur.
That would be the O2 sensor after the catalytic converter.
Your 1999 Chevy blazer doesn't have a timing belt.
Will a 1997 blazer what work on a 1999 blazer????? If your talking engine, transmission, or running gear than yes. It is all the same.
That vehicle has several oxygen sensors and they are all threaded into the exhaust at various points.
1999 Chevy what? What kind of 1999 Chevy. different models have different sensor positions
Mostly, yes.
how to drai torque converter on 1999 chevy blazer
NO. Not even close. Chevy redesigned ALL the TRANSMISSIONS and ENGINES in late 1999. Anything above 1999 WILL NOT FIT anything under 1999.
