Re: Water Temperature Gauge Fluctuations Group: alt.autos.gm Date: Sat, Jan 10, 2004, 3:52pm (CST+6) From: snipped-for-privacy@nc.rr.com (Jack=A0Coyle) Apologies for the delay in responding. Couldn't get to a computer during the week. To answer your queries:
1) The flunctuations appear to be impervious to operation of the turn signals. While there is some variation in the needle movement when the turn signals are on, it doesn't appear to be any different than when the turn signals are not on.
2) The temp sender screws into the manifold, just beside the gooseneck for the water return hose.
3) The vehicle has an oil gauge and it appear to register accurately.
When you say bouncing you mean 1 up and down almost like your spedo gauge or 2 you mean it goes up for a while and then the temp drops then slowly goes back up then drops back down.?If its #1 you have a bad temp sensor.Or gauge if its #2 you have air in your system that needs to be bled out....
