Thank you in advance for reading about my truck and any solutions offered.

My temp gauge used to stay put on the cool side and never fluctuated much.

I recently drained my coolant because it was looking murky brown.

After draining, and refilling with 50-50 premix, my temp gauge now bounces,

not a fast bounce, but goes from cool to hot back to cool then back up...

If I get out on the highway it seems to level out and doesnt move much, but

in town, like pulling off from a light, it will rise up and then go back down.

It never overheats or gets into the red

or even over over the normal line close to the red - Like I said, it used to stay put on cool and never moved much.

Whats my problem? Is there a problem?

You could have air in the system. Somebody who knows more will jump in.
 






When cool check your rad level and the level in your overflow. Is the coolant going brown again? does it smell funny? If so could be combustion gases getting in to the water jacket via head gasket or crack.
 






yeah its brown again
 






Dang!
 






Dang!
 






Oops, sorry!
