copperjohn Posted May 14, 2013 Share Posted May 14, 2013 What would make a heat gauge stop working? Has anyone had this happen? Link to comment Share on other sites More sharing options...
danhar1960 Posted May 14, 2013 Share Posted May 14, 2013 Probably the tube has broken.Danny Link to comment Share on other sites More sharing options...

copperjohn Posted May 14, 2013 Author Share Posted May 14, 2013 Yep! What Danny said. All the ether in it has escaped. They can be repaired!CheersGrantAre these difficult to remove? I looked at the connection on the motor and am not sure how it's connected to the block. If the square nut is threaded or pressed in. Don't want to damage anything.

danhar1960 Posted May 14, 2013 Share Posted May 14, 2013 The bulb in the head can be a real mongrel to get out but on the upside, it's already not working so you don't have to be quite so careful.Remove the retaining nut and start applying WD40 or something similar. It should just pull out but will be held in by years of gunk and rust.Just be patient and it will come out though it may take some time for it to loosen up.Danny Link to comment Share on other sites More sharing options...
Dwight Romberger Posted May 14, 2013 Share Posted May 14, 2013 To bad John. You just missed the Ether Bunny!Sorry, I couldn't help myself.Mine also failed. I bought and installed a cheap tube one (19.99?) that had the same diameter gauge as the original. It will serve until I repair and refill the old one.

copperjohn Posted May 15, 2013 Author Share Posted May 15, 2013 I want to thank you all for your help. Is there a photo somewhere showing this bulb out of the engine and where do I get it repaired? It was working fine until I had some work done under the dash. Link to comment Share on other sites More sharing options...
Guest Grant Magrath Posted May 15, 2013 Share Posted May 15, 2013 I can't remember whether you can get at the back of the bulb by removing a head bolt nearby. Anyone?CheersGrant Link to comment Share on other sites More sharing options...
60FlatTop Posted May 15, 2013 Share Posted May 15, 2013 Although the gauges are nice, a well maintained cooling system is more reliable than a gauge. Don't run hoses and belts that are more that 10 years old (7 years is good), check the pulleys for wear and be sure the crank damper is OK, Open drain cocks to be sure rust and sediment isn't building up, change the coolant and flush (it could cost $50 to do it annually, what's you cat worth?), use a thermostat if the car came with one, if water drips from packing when the car sits it will probably draw air into the system when it is running.Bernie Link to comment Share on other sites More sharing options...
