temp gauge

Well I have a problem with my temp gauge. It's stuck all the way up and won't come down. I've taken apart the cluster and took it down, but when I start the car it just does it again. Could this be a problem with the gauge?

I had the same problem, my gauge was bad, got one on ebay for like 10 bucks, id say that is your best best, but i guess it could be your sending unit but ill bet its the gauge, just look on ebay for one or ask in the classifieds here. good luck

If the guage is pegged, check the wire to the sender. It may be grounded out on the exhaust or something.

When you start the car the temp gauge goes to max then comes back down(this is the correct movement).When you remove the gauge from the cluster does the needle move freely?The wire to the sending unit is grounded like bingo suggested.The sending unit is on the driver's side head between #1 and #3 sparkplugs and the lead is dark green.
