For starters I have an 85 GSL

I am putting a new rad in so I am switching over all the sensors and whatnot.

What is the sensor on the bottom of the rad. Clips into a small harness type thing on the same cluster of wires as the coolant level sensor wire

Checked the manuals. Out of all the wiring diagrams i could NOT find this sensor or even any sensors with the same color of wires (blue with yellow or maybe white stripe and black which im assuming is ground)

Can someone tell me what this sensor is. To me it looks like a temp sensor but i know thats near the oil filter.

Cant check what doesnt work by unpluggin it as non of my guages work.

A few pics are there

I believe it controls the fan clutch.

 

I thought the fan clutch was entirely mechanical and not electrical... and thats why it looks similar to a heatsink

Or am i mistaken?

 

I could be wrong, I'm going by the Victoria British catalog. I can't find it in the parts catalog.

 

and its not in any of the wiring diagrams or pics in haynes, but its definetly stock wiring and colors. I never thought of taking a look in VB or maybe ill check mazdatrix see if they have somethin

 

Screws into the bottom drivers side pointing back (so its in the engine compartment) plugs into clip near the battery where a bundle of wires mosy back thru firewall

 

found it, parts catalog lists it as Thermo Switch

 

This is part of the automatic chock pull off. If you have a 79-82 or SE carbed, and you order an aftermarket radiator, they will send you one without the hole for that sensor. I have seen that a billion times.

 

awesome thanks bad 83.

 

Isn't the choke switch behind the water pump ?

I've got an '82 and a replacement 3 row radiator with that hole.

 

hmmm. second opinions then? and it should still be in the wiring diagrams...

 

looks like I'm wrong.

In the '82 wiring diagram, Section B, component B-11.

Goes from ECU, that thing is No 2 Water Temp Switch (rad), then goes to No 1 Water Temp Switch (Eng), then to wire that comes off the Choke Switch to Hot Start Relay.

 

here and do you know where i found this you got it ,the FAQ at the top of the page go figure.

I apologize 3rd and final, but i figured since i knew it wasnt the water temp (gauge) sender that it would be under that. Clearly i was mistaken.

Thanks again (and really it was at the bottom of the faw page lol...j/k)

 

its toward the bottom yes but the FAQ page is at the top of the 1st gen section!
