Uni O2s the same as factory?

[Buick350X]

Since I found such a helpful site thought Id ask.

 

Moms Sub needs a bank3 4 wire O2. Didn't know there was even a 4 wire out. Had bought her a uni 3 wire bosche kit off ebay for $20 but I'm one wire short.

 

Just thought I should ask to make sure before I buy another $20 Bosche uni 4 wire kit.

 

AZ wants $60+ for the sucker

 

Also the O2 or light saying the bank 3 O2 was bad, was after I ran some marvelous mystery oil in the gas. At first I was able to make the light go out if I drove the car and got on it hard. Kinda blew it out. But its on constant now and gonna change it.

The only differences from the 4-wire & 3-wire O2 sensor is that the 4-wire sensor has a sensor ground as well as a heater ground, rather then grounding the sensor through the chassis.

 

If you use a universal one, you need to make sure you solder the wiring good and seal it up so water doesn't get in.

Has anyone here done a thumbs up or down on that cold heat solder tool?

you'll find that you won't really be able to solder those wires... i tried a torch.. and it couldn't get it to take the solder...

the universal kit somes with a little black box, and yellow thingers that go inside.. it's a paint but it seemed to work for me.

I'd get a real soldering iron if i were you... stuff advertized on tv scares me

Andyjo, this sounds strange, but I'm glad to hear you couldn't solder the wires on the Bosch universal O2 sensor. I couldn't do it either, and thought I must be losing my soldering skills. The solder just wouldn't wet the wire no matter what I did. The wire must be aluminum or something else, definitely not the usual tinned copper. I gave up and used the fancy connector supplied by Bosch - it's complicated, but went together easily and looks like it will be durable.

Cold Heat = Thumbs Down in my book. I'm an electronics technician and bought one thinking it would be great for field work. The tip is basically a fork and only when you short the two sides together with what you are soldering will it heat up. Even then I wasn't confident I was getting proper heating. I would just use a corded iron.

Ya know I had thought that for a while cause in one of the shots in the

commercial you can see it spark. And from the spark it looked powerful.

Maybe it just like a mini stun gun. Why it doesn't get hot. Just hi volts.
