Thermostats and Thermostat Housings

Which of my observations are you disagreeing with

Actually if you disagree with my observations.....End of Discussion

Oh.....Five ZR-1s all running Aluminum After Market Radiators and ALL with 180 deg F New Thermostats installed.

Based on that info, I would agree. If the temp is above 180, I would expect the thermostat to be fully open. I don't think my temps ever exceed (under normal driving conditions) the expected temps. However, I've never watched with a digital.

On the AC/Heater head unit, hold the Up and Down Fan Buttons until a -00- appears. Then use the Up or Down button to change the number to -16. Hit the center Fan button. The AC/Heater display will now show the engine coolant temperature in Celsius. In my experience, with an aluminum radiator and 180 degree thermostat, it should stabilize somewhere around 90-95 degrees C.

Or buy a 92ZR and check coolant temps as most other humans do.

Yes....you describe perfectly how to get digital Readout of Coolant Temperature in deg C on the AC Head Unit on the 90'-91' and I assume 92'.

On the 95' you can press GAUGES on Dash and get Digital Readout of Oil Temperature and Coolant Temperature in deg F on the SPEEDO Cluster (I think where TRIP Information is shown as I recall). Pretty Cool I would say

And YES.....the Coolant Temperature on my 95' stabilizes right around 90-95 deg C on a 90+ deg day with a Fluidyne Radiator installed
