Thanks, I feel better now.
I want my engine to run just above the thermostat temp while cruising on the highway. Right now it doesn't so something isn't doing its job.
Yes, I know 198 is not overheating so I really don't have to fix it. As long as it doesn't get higher than that while idling in traffic it's passable but not ideal.

Anyhow I got the Milodon high-flow 180 degree 'stat this afternoon but it's too hot to run around draining and refilling coolant today!
