Got it on the new sending unit and radiator. I too was wondering if the radiator is OK as I thought the same thing (temp drops quickly after slowing down). I do have the Robertshaw/Flowkooler 195 thermostat.

Once I have a laser themometer to check this I will follow up. Thanks again!

Chris,

I fear you are stuck under a preconceived misconception.....
The thermostat in the cooling system does not determine how hot the engine gets, but how cold it runs. If you think that way, thinks will go better. 195°F if the temperature when the coolant starts to go out to get cooled. When you stop putting heat into the system, it will (relatively) quickly return to that temperature.

If you have any reservations, I could come along on a ride-around (and bring my own IR gun) and we can check things. Your sig says SE-MI like mine, well we live in the shadow (really) of DTW and if it would quiet any nerves, I would love to help.
