Temperature Sensor vs Temperate Sender Unit - 1984 Nissan 720

[bluexl]

Hey everyone. A mechanic who worked on some electrical items for me, and seems to have done a really good job told, me I need a new temperature sender unit. However, all I can find is a temperature sensor. He said that was not it. Can anyone offer any input/guidance on finding a "temperature sender unit" for a 1984 Nissan 2WD truck? Thanks.

The temperature gauge sender is 25080-89900 and mounted close to the thermostat. Take this number with you to an auto parts store. they can probably cross reference it.

 

The engine coolant temperature sender was used by the feed back carburetor's control unit. It supplied information as to how warmed up or cold the engine was so that the mixture ratio could be properly tailored. For the '84 it was 22630-V5010. Earlier ones were near the thermostat also but later ones were in the head near the exhaust side number one spark plug. These gave a faster more accurate indication.

Thanks! I am taking this info to the parts store.

Autozone has them for 19 bucks with a lifetime warranty.Go ahead and replace the sensor too.You probably will have to order it. Ebay has them for 11 bucks.https://www.autozone.com/engine-management/coolant-temperature-sensor?filterByKeyWord=temperature+send+unit&fromString=search&isIgnoreVehicle=false.....https://www.ebay.com/itm/371477771169?fits=Year%3A1984|Model%3A720|Make%3ANissan&epid=22051621978&_trkparms=ispr%3D1&hash=item567dccf3a1:g:~ecAAOSwXfVa4yVd&amdata=enc%3AAQAGAAABAOfZj6YOBL%2BFdrxQ9Lj4R7uQzoDfS5MOIEC4fE2bmrzSGhWgUlq2nbyFpNeF0%2FZSgo3IHk4VB%2FKaj7OUsZzdW0QA%2FLTMEnt7Az4i3FC4mT1GsiyWiO%2BGHT6lObKzc6Tfn36Mh6LQuAHU2SFUM87U8uO%2BKxC84PGhTX%2BsH9%2FZZhPpb93WxmtFFMgSEmTXZEhjFzDgU%2FnO9nSRCnKFM51Z8gzFbZ%2F7yg1XApo4Tu6ovAqLaM6TmAqj5c6mXOPOQZTxP2%2B6p7TqChoHEqpcx0XfiZvj6va3pHmHzqW0xztvLXEcXYLR7Q0idINJf1jHYcyTQHQe8poQY7djBOmfPZO93NU%3D|tkp%3ABFBMzOPF-ZBg

Check the number again I had to correct it.

 

If from California then you will have the feedback carburetor with both the sensor and sender.

Yes, it is a California car. I found one at Autozone:

 

HUB PART - Temperature Sending Unit TU100 Duralast - 000019135  TU100 $18.99

I hope it is the correct part.

 

Thank you.

Sensor vs sender

 

Sender usually is for gauge only.

 

Industry term "sensor" usually refers to a module that gives information to affect tuning.

Thank you everyone. I was able to locate, order and replace the part. The Autozone part no. is TU100 68-005 and can be seen in the images below.
