521 temp gauge

[dbuzz77]

what are the common problems for the temp gauge not working? the connection is tight on the sender and it shows some resistance. thanks

I was having a problem with the temp gauge in my 210 because it got all gunked up and nasty. I pulled it out and cleaned it up with some carb cleaner and it works like new now.

Air bubble in the inlet to the sensor? Bad voltage regulator in the instrument cluster?

A bad v/r will affect the gas gauge too.

 

With the key on ground the sensor wire. This should cause the gauge to read full hot. If not pull the gauge cluster and check the connector and the meter connections.

Is your gas gauge working? They both use a regulator on the back of your dash pod and if neither the temp or the fuel gauge work, that regulator is the first suspect.

 

I pulled mine, took it apart and tried to clean it and it still didn't work. Thankfully I could still get one from Nissanparts.cc.

 

If you download the parts number book from olddatsuns.com you should be able to get the number for it. I think it was like $24 or something.

Then the sender unit is kaka. Any L series sender will work it doesn't have to be for the 521

[dbuzz77]

nissan still has them?

[mklotz70]

any parts store should have them :)

you can get the senders EZ

 

the hard part is breaking that 16mm hex holdeing the sender in. What usually happens is you break the Lower stat housing!!!!!!!!!!!!! BE CAREFUL OR USE A TORCH TO HEAT IT. Or have another lower housing ready to go with a new sender and hex nut. I cracked one or 2 in my time. I just now have spare lower stat housing incase they go bad.

Go to junk yards and get spares or from other peoples L motors when they upgrade to KA/SRs

i just moved back to this area and am scrounging to find wreckers with this old of stuff. i will be careful, i broke a tstat housing when i was 18. i still have to find a sensor.
