1997 4.6 temp problem
So today on my way to work my temp gage went from normal then rocketed to red for a 30 seconds then back to normal. Second time its done this. Any ideas? Temp sending unit bad?

I installed a flush kit on mine. Its a plastic T that you install inline on one of your heater hoses. Cost you about $10 from auto zone, etc. Hook a water hose up to the T and take your reservoir cap off. Let the water hose run for a little while to push out any air pockets and place the provided cap back on the T. Not sure how everyone else does it, but that worked for me. You can then pour anti-freeze in the reservoir and run the engine to mix it. I'm in FL so I don't have to run much of a mix.

Ill try that. Because the resivor is full and I felt the hose right as I got home on a still running remp engine it was soft not hard. So im thinking maybe a radiator cap, flush, and maybe a thermostat? Just to be safe? It also had coolant sprayed around the cap/resivor and the coolant wasnt a very healthy color. A dark green almost like a moss green not bright coolant green.

I would make sure you flush the block by taking out the drain plugs in the block. A blockage in the block can prevent the air from getting out and develop the hot spot you are experiencing. There are a couple of you tube videos that show how to flush and drain the block.
