Q: Temperature problem

asked by on November 12, 2016

When I start my truck the temperature needle will read cold for a good 5 min and then start to.jump around going.from a little high to a little.low. While driving on the highway it will hold normal temp with a very slight change. Would this likely be a temperature gauge issue or a possible leak?

My car has 165000 miles.
My car has an automatic transmission.
