So I'm trying to figure out if I have a gauge issue.
First my speedometer and odometer went out at the same time (the day I changed my radio if that has anything to do with it) I know the fixes for both of those but I'm just trying to confirm before I buy the parts that's it's not something else cuz I haven't read that both of them go out at the same time.

Second my temp gauge keeps fluctuating I would understand if it was hot and fans cool on but sometimes the gauge goes past the red but I check the hose and radiator cap and not even close to being that hot. ( I have a 180' thermostat)

Even my oil is showing it too full having the needle all the way to the right, and my gas is also fluctuating before I bought the car I was told that the fuel pump was replaced so that might be the cause of that.

So I'm just trying to figure out if I will need all new gauges. But my concern is the temp and oil I don't want my car to over heat

Thank you

if the speedo and odo go out at the same time, the usual culprit is the gear on the vehicle speed sensor. NOT the cluster gears (which are also super common)

And just to clarify, your oil guage doesn't tell you the oil level. It monitors oil pressure when motors running.

If all your gauges are acting funny, try finding the common ground for the dash gauges. I'm not familiar with the SNs, so I don't know where it is exactly, but a little Google search will help with that.
