TEKTON 3/8 Inch Drive x 7/8 Inch 6-Point Oxygen Sensor Socket | 4929

Item works great

I purchased a generic O2 sensor socket set along with my O2 sensors. When I went to work on the car, the darn crappy sockets slipped. I spent 3 hours spraying penetration fluid, heating, praying, swearing and trying to work the O2 sensor free using the crappy set. I then went on Amazon and purchased this socket along with another style from this brand. As soon as I got it, I noticed a nice strong heavy metal quality to it. The generic ones were a lighter and cheaper alloy. Once I got the hood up, the upstream sensor was out in 15 minutes. For the down stream sensor, I had to use a 26 mm wrench on the head of the socket to take it off. I also used a metal hose clamp around the end to prevent any chance of slippage. Just for reference, I tried using a 22 mm close end wrench, but it wasn't a six pointed, so it slipped. This took me about a half hour as I had little ground clearance. If you're going to change your O2 sensor, I would recommend getting this brand. Save yourself a lot time, aggravation and money. Don't cheap out on the socket like I did.

Decent quality put A whole lot of crank on O2 sensor to break loose and did not slip or crank.

The TEKTON Oxygen Sensor Socket is durable and easy to use. It grips the sensor securely without rounding or slipping. A great tool to have for quick and reliable automotive repairs.

This socket is well made, and very durable. However, there is a major flaw. Like some of the other reviews I had read, this socket started to round out my o2 sensor nut. It's not so much the slot from the wire giving room (another review recommends a great remedy to this), but the fact that this is a "7/8 (22mm)" and most cars with foreign parts use metric measurements. That said, the difference between 7/8" and a TRUE 22mm socket is very small, but enough to cause damage to a nut if it is seized in tightly. I even purchased a 22mm deep socket, but the nut was too rounded by then for it to work. After some knuckle busting and more than a few choice words for the situation, I was finally able to get the nut to start moving, using locking pliers with a torque lock to "dig" into the nut. It was then that this o2 socket did its job. When installing the new o2 sensor, the socket worked like a charm!! Bottom line: Great for installing a new sensor! Not recommended for removing a seized or tightly rusted sensor (it's best to cut the wires of the old and use a true 22mm deep socket, or even try the clamp on the socket trick). If you're not sure how tight the sensor is, always assume it's locked in good and don't run the risk of rounding the nut!

Using the suggestions of others, I grabbed a hose clamp to ensure the Socket didn't flex outward, and the old O2 sensor came off easy-peasy. New one fit in just as easily, hand-cranked until it was reasonably tight, gave a couple of cranks on the ratchet to ensure it was snug, and the car started right up with absolutely no coughs or sputters, and no wear shown on the socket at all. Granted, it's a little early to suggest the durability rating is great (I mean, how often does one have to change O2 sensors?), but if it lasts long enough for 1-2 more changes, then I've definitely gotten my moneys' worth.

Excellent

If your car is newer, or you don't live near the shore, I recommend this product. In my case, my car is older and I live near the shore, so my O2 sensoer was in there TIGHT. I ultimately needed to use the claw foot style and a 3' pipe to get mine out. This did work well on my sons car, so there is nothing wrong with the product... it's just that the claw foot type is probably a better option if your O2 sensor has been on a car in salt air for 14 years. At the price, I would buy both, as installation is MUCH easier with this socket than the claw foot type. The right tool for the right job.
