sandman Posted October 5, 2010 Share Posted October 5, 2010 I have a 582 with a water probe that has 2 wires extending out an epoxied hole in the probe and appears to be faulty now as it some times works, the needle sought of comes up then drops off, the last probe I had did this and I thought it was the guage so bought a new guage and later found out that it was the probe. I see MGL have a water probe with a one wire attachment to it and no epoxy in the centre, can I use this probe instead of the 2 wire epoxy one as it is giving me grief. Cheers.

robinsm Posted October 6, 2010 Share Posted October 6, 2010 The probe that fits the standard hole in holden engines is the one that I use in my 582. Thread and nut on the top to take the sensor wire. Probe is earthed through the brass body of the probe. Link to comment Share on other sites More sharing options...
sandman Posted October 14, 2010 Author Share Posted October 14, 2010 I went down to Supercheap and the water probes they have there have a longer probe that goes into the coolant, will the longer probe hit anything when I put it into the head of the motor or do I have to get the same length prob as the original one.

robinsm Posted October 15, 2010 Share Posted October 15, 2010 The probe sits in the water jacket around the cylinders, unless it is longer that 6 inches it wont hit anything. Link to comment Share on other sites More sharing options...
