replacing front oxygen sensor

[buff51p1]

My service engine light came on and the code said the front oxygen sensingunit was bad. Should I replace with OEM or aftermarket and is it difficult to replace, any special tools required.thanksBuford

The front sensor should be a cake walk. Aftermarket should work fine, but make sure you price compare them and look for "name" brands. If you need some direction on replacing the sensor, LMK and I'll post it up when I get to my "normal" PC where I keep my manuals...

The front o2 for the rear bank is a bit of a bugger to get out but can be done by going through the right hand fender well where the tie rod goes through the body opening. The front o2 for the front bank is a bit easier. located near the bottom by the cooling fans.
