I have a 1999 Chevy Blazer 4.3 v6 we just replaced them there is three two up stream and one down stream. If you get under there and look you will find them with no problem. I'm a woman and I found them with no problem. two on passanger side one on drivers side. unless you have two catalitic converters then there is 4
three
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.
It does not have a fuse sorry.
It should have 4 of them.
I'm not sure, but I do believe it's 3!!!!
That vehicle has several oxygen sensors and they are all threaded into the exhaust at various points.
Your 1999 Chevy blazer doesn't have a timing belt.
yes! one in front of converter and one in back of converter.
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.
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.
