1952 Plymouth Cranbrook Temp Gage

[Leo White]

My temp gage in my 52 cranbrook is not working and I can't seem to find any info on how to fix it.  Has anyone had this issue or know how to fix it?

Well, it is mechanical, not electric.  It screws into the back of the head on the driver's side.  There should be a metal tube that gores into the firewall and ultimately to the gauge.

Yes I have found that part lol, just not sure what to do to fix the issue.

Is the tube cut?

I see what looks like a break line going to the bottom of the engine block then there is a cable with a spring wrapped around it going to the top of the engine block

This is what it looks like from the gauge cluster, the tube with the coil spring goes directly to the port in the head.  I think the line to the bottom of the engine block is you oil pressure gauge.

Yes I was just about to say one is for the oil gage

That tube to the temp gauge has to be continuous with no breaks or holes in it.  There have been some that have fixed the tube, I am not one of those so I dunno.  There are also companies than can repair them for you, again I haven;t dine that so no advice there.

Thank you for your help as always it is much appreciated.  This is my first vintage car and I am not a mechanic but I am trying to learn.

Check out the tech tips on this forum, they are listed in the header at the top of the page. There is a lot of good information there.

A good Speedometer shop can fix it fast and they will check the calibration too.

This is one of those items I don't bother trying to fix myself. If in doubt...send it out.

You'll be money ahead.

Also with all the electronics these days, these guys are like shoe repair guys. If they are still in business they probably do good work and you need to support them.

I sent mine to Autoinstruments in Martinsville, Va. for repair. $235.00. Be sure you are not in a hurry to get it done unless they understand you need it promptly.

I agree I am taking my car to a local garage next week and think I will have them look at it

I repaired mine using the info on this site and froze the bulb in a cup of water before starting and used JB weld instead of soldering and it has been working fine for several years.

I'm another one that fixed his gauge using the advice found here.
