hi Jack.. I won't say what my experience and opinion of Oregon weather is ... let's just say I lived a long time where it's very nice and pleasant a lot.

re Do the senders report coolant temp regardless of whether the thermostat is open or closed? (Mainly this is something Marius is wondering about.)

The temp sensor 'just reports'. Not related to what the t-stat is doing directly.

the t-stat is not so much in one state or the other .........open, or closed.. it's a variable size opening that allows the 'right amont' of coolant to circulate from engine to radiator. Ideally.. the system is never running at it's total cooling capacity. Like there should always be some reserve cooling ability remaining. The t-stat also has another feature .. when the engine is cold..........coolant circulates around and around in the engine, through one part of the t-stat. As that coolant warms up, it starts to close off that part of the t-stat and open the other pathway to the radiator. Eventually all coolant is going through the radiator. If more needs to flow to maintain the desired 180F or so ...the t-stat opens a little more. If the radiator tries to cool things to much , like what would be below the desired 180F or so, the t-stat closes a bit.

the heater ciruit btm ..is full time flow, independent of the t-stat, as long as the heater vavle is open. This means that in really cold temps ..the heater circuit can cool things too muchm especially at first. . and it will take a long time to get up to fully warmed up. It's useful in very cold temps to keep the heater temp lever mostly 'off' for the first few minues of running so the hearter ciruit doesn't ccol things too much intiially.

I like the stock temp gauge a lot btw. I don't think an aftermarket coolant temp gauge is needed much at all.

yeah..keep saying what German Transaxle says.
