Hello I have a mazda b4000 which is pretty much a ranger. My temp gauge is not working wont even move. Its below the cold mark. I found the temp sender unit (1 wire) and the coolant temp sensor (2 wire). I pulled the connection off the sender and grounded it out and my gauge went past full hot. now to my problem. I go to buy a sender unit but the one 3 different part stores tried to sell me looks nothing like what I have. My sender unit looks exactly like my coolant sensor. is that right.

 

this what all the parts store try to sell me.

 

This is what my sender unit looks like when I take it out. Looks exactly same as my coolant sensor. just the connect to it has one wire when my sensor has a 2 wire connection. Is this correct?

 

Yes, that is correct

 

Question is then how come all my parts stores try selling me pic one then?

 

Not sure why?

Try 1997 Ranger 4.0l OHV temp sender, should be $10-$15, sensor is over $20

 

Thanks a bunch thats the exact one I needed. I'll just tell the parts store from now on I have a ranger instead of a mazda lol.
