Hi I have a 94 753 Bobcat with a 40 hp Kubota engine. My bars on the coolant temp graph never goes over 1 bar. I assume my temp sender is faulty. Where is this located so i can replace it? Is there an easy way to test? I thought maybe it wasnt getting warm enough so I replaced the Tstat last winter and ran it with the rad covered. This summer I have used it occasionally and no more than 1 bar. I want to make sure it doesnt overheat. My oil pressure never shows the bottom bar, but the 2nd 3rd and 4th light up when it is running. Thanks
