Engine coolant temp guage

Hey guys, I have talked about this before about my guage acting up. So I changed my water pump my t stat and my ect sender that threads into the water pump. Everything was fine till yesterday it acted up again. It said it was running hotter then it should of been, then it would drop to normal keep jumping up and down like a 1/4 of an inch from normal.

So then I started wacking the dashboad right above it and it started going nuts jumping really fast then stopped. Any ideas please help. I'm getting worried when I c a above normal reading on the guage.

Chris

If it moved when you whacked the dash then I think it's safe to say the problem is in your dash.

Yeah after I wacked it it stopped but it does it on its own that is the funny part I'll just be driving along and all of a sudden look down and it warmer then usual. Is the temp guage have two sets of wires in the back maybe one is loose?

Wiring issue I'd say, if whacking the dash makes it work

IIRC I think there are 2 plugs back there...

Next question then is how do I get back there and also is there maybe a fuse to it that I should check? But really how do I get into that guage cluster.

If you have a factory radio you'll need a special tool to get radio out. Not sure where you can get that except for tool trucks. Then you have 2 screws in the radio area and the rest just pops off. Once you get the cover out of the way then you have 4 screws to pull the gauge cluster out.

Any idea what this tool looks like could I use a coat hanger? And when u say the rest just pops off you mean like I need plastic tools to pop them from each other? Where are the seams where everything pops apart from each other is it in halfs or something along those lines?

I doubt a coat hanger would work. It's 2 "U" shaped steel bars that go into the little holes in the face of your radio. The dash cover just pops off with a little tug and you don't need tools for that. You'll see the line where it comes apart. I think it should even be different colored plastic.

Okay I know what you mean now So the radio has to come out first then I should be able to pull the dash apart. What about the sterring wheel and all of that? It can stay right there right?
