Well, I think I may have been given a 160* when I bought the 180*. Silly me trusted the parts guy and put it in without double checking his work. Anyways, I have been monitoring my engine (L36) for months now and now that the summer is hitting I'm realizing that even in the mild mornings (40* ish) my engine warms up to 180* during city driving but highway drops to 161* +/- 1*. My thinking tells me that I should be bottoming out at the 180* +/- 3* with a 180* thermostat.

Keep in mind I do have a larger radiator. It was up'd in anticipation of my top swap. As you'll see in my other post I have a UD for the water pump on its way.

Do you all think its normal or should I buy the new gaskets and check/replace it?
