Thread: temp gauge

Any gauage will only be as good as the information getting to it.

Aside from fixing your immediate issue (about which I am the last person to have any idea on how to fix), consider getting an Enginesaver alarm with a separate (and more accurate) digital readout of actual temp.

yah have seen the posts on the engine savers and will definately be getting one fitted in the near future , i thought they were just an alarm and a light to warn you of the sudden loss of coolant. so they do give a temp reading ? best brands? easy for a mug like me to install?

Temp gauges are a common problem in older cars as it's usually caused by dodgy connections... Usually ones which have corroded over time.

The most common culprit is the earth connection...

PS. You might want to try doing a forum search next time...

Yeah maybe you're right about the engine savers... the one I got (and installed myself so it must be easy ) is an Engine Watchdog TM2... not a low coolant alarm but a temp sensor.

Others on this forum speak highly of the Engine Saver low coolant alarm - so check the threads out - and I'm guessing you can rig those to give a temp readout as well ??

The ground line comes from battery to chassis. There is also a thick line between chassis and engine. It uses one of the starter fixing bolts.
Usually you can loss some volts in these connections, varying with current demands from A/C, lights, etc. when the fixings are corroded. This can modify temporarily gauge readings as You wrote. You just undo and redo this four ground connections and the trouble is gone.

I agree that Discos must be protected with a overtemp and coolant level alarm. I did myself this http://ar.geocities.com/vigiland4/Vi...l/Vigi_tip.htm in year 2003 and a lot of disco users did it too!
