Question 4

See i have a 2000 sr5 4x4 4runner and i need both 02 sensor part # please also how many do I need

Accepted Answer

I have a Tundra and have replaced all sensors (4) in my vehicle. The Tundra has a devoted dual exhaust & 2 catalytic converters, one for each side (Driver's / Passanger) of the engine. The exhaust then either combines into a single exhaust pipe seen at the back of the vehicle or maintains separation (devoted), in which case there are 2 exhaust pipes at the rear of vehicle. I'm not sure what configuration your 4runner has, or has been modified to, but can tell you this. What O2 sensors there are go on the exhaust before and after the catalytic converter/s and so a quick inspection under the vehicle should tell you whether you need 2 or 4 sensors. The UPSTREAM sensors (before the catalytic converter/s) on my vehicle bolt into the exhaust by threads on the the sensor itself. The DOWNSTREAM sensors have a double holed mount that 2 bolts from the exhaust pass through and are tightened into place with hex nuts. You will need a slotted socket in order to tighten the UPSTREAM sensor on without to much of a problem. It's not worth trying to do it any other way. Use caution to not to slow turn & break the sensor or mounting bolts when taking them off. I would recommend hammer tapping as opposed to a steady torque force to snap the frozen nuts free for turning. Once free, but still extremely tight, penetrating oil will be able to be sucked up into the threads for further loosening, but until the nuts or sensor has snapped free for turning, penetrating oil won't be of much assistance. Good Luck
