Part number & name?? A/C cutoff sensor (1 Viewer)

[jbee]

I'm looking for the name and part number of the sensor in the middle of the picture. It's the sensor/switch that turns your AC off when the engine is overheating. I've read every thread about the sensor and it's function and how to test it, but can't figure out how to buy one.

I've been looking for two weeks and cannot seem to find an actual name or part number for it!
Anyone?

For R134a systems the Denso part number (1996 FZJ80) is 443440-0050.

Edit: sorry, meant to delete this a few hours ago as I was going out the door but looks like it didn't work. I misread your post, the part number above is the pressure switch located on the AC line up by the battery (front left) on a US spec FZJ80.

Thanks! That's for sure a sensor but I think the wrong one. It's the pressure switch for the a/c.

Here's a reference from a Russian site with a part number; can anyone confirm this? Image search does not show the sensor I'm looking for.

That looks like I think the coolant temp sensor on driver side head of North American 1fzfe above oil filter

See edit above: I misread the original question, the part number I posted is for the pressure switch located on the AC line up near the (left side) battery on a US spec FZJ80.

No Problemo! I'm still looking ...

Here's a good illustration from the same Russian LC site. I'm looking for #2.

New info. Have not found a Toyota part number that matches up with a picture, but here are some aftermarket part numbers and photos. The aftermarket makers are calling it an A/C Switch, Radiator Fan Switch, cooling fan switch, etc. First photo is of the switch on my motor.
88790-60050 is the cross reference suggested, but Toyota parts sites have differing part descriptions and photos.
In some places it's a thermo switch assembly, in some places a Valve Assembly Magnet.

Why not just pull it and read your number

Uhh, wrong sensor. There are 3 or four of them there. I'm confident in the sensor I'm asking about. It's the one that allows the a/c compressor to kick on when you unplug it, even if the engine temp is 239 as read by the computer.
It would be nice to have the new one on hand and just replace it at the same time. At 172k miles who knows if the number on the old sensor will be readable.

The part number is 8879060050
"THERMO SWITCH ASSY"

Hate reviving the dead but hoping someone can chime in with some help.
When replacing the engine knock sensors I barely nudged the neighboring Thermo Switch and the connector crumbled away.
We've all seen these 20+ year old connectors crumble so I thought for sure someone would know the PN for that plastic connector to replace.
Simply can't find, hoping somebody has some insight on this.

Plug this number 88790-60050 into google image search and see if it looks like yours.

The one I ended up using was an aftermarket part from a US source but was stamped 'made in Italy' on the actual sensor.

 

[TRD_Dan]

That is the PN.
That's how I found this old thread.

What I am in need of is the plastic connector that disintegrated in my hand.
Someone on Facebook mentioned they found one that worked from Ballenger Motorsports, but gave no more info.
I called up Ballenger and they couldn't help without more info.

Do you have a link to what worked for you?
And was the sensor or the connector stamped "Made in Italy"?

I swore there was a thread on this forum referencing the "ultimate connector thread" or something like that but I can't find it.

Do a search on this forum for the part number you have. Then read those threads to see if someone has posted either a pic or a P/N for the connector that fits it. Then you can buy it from Toyota. You'll have to either splice it in or pin it in if the wires work but the housing crumbled.

Try the search terms, ‘ fzj80 engine harness connectors’ or variations of that. Start with Google, ‘mud does a good job of capturing searches that have FZJ80 at the beginning.
I know there’s a thread out there that has pictures of all of the harness connectors and their part numbers.
You could also search for photos of the engine harness and you will see the plug on there, I will check with my local Land Cruiser shop to see if they have a spare connector.

I'm about to pull this sensor (I've seen it called "Engine coolant temp relay," "Water temp SW for AC," and some other things, but it's the relay that has caused my AC not to work). I've pulled off the electrical connector, and the AC now works, so the sensor is my issue (I'm quite sure the engine isn't actually overheating). The sensor is covered in oil from before the head seal was replaced, and there is oil inside the connection. I'll clean it up, do the hot oil test on the sensor, and see if it works. When I pull it, will coolant leak/gush out? Have others drained the coolant to below that level, or jammed a rubber plug in the hole while the work has been done? Is there another trick to this?

 

[jbee]

It will drain some coolant, but not much. Maybe enough to drip on the ground. It will not gush out. I changed both of those sensors along there at once and I think I lost maybe 6-8 oz of fluid.

Cheers. I appreciate it.
