The temp gage almost immediately starts to register. The indicator shows a little below normal operating range within a minute or so. I have recently replaced the temp gage and capillary tube. I am wondering if maybe I have a stuck thermostat? of maybe the water pump is not working properly. Any ideas from any of you with experience like this would be greatly appreciated. Thanks, Lon.
