does anyone know at what temp. your fan should kick on at. a friend of mine has a 2000 teg and the temp. gauge is broke. he blew a radiator hose today, fixed it. we were letting it run but the fan never turned on. we used a guage to read the temp inside the upper and lower radiator hose and we reved it up to about 240 degrees, but the fan never kicked on. does anyone know
