Bought a RTV about 3 wks ago with under 10 hrs on it. Noticed that the temp guage will get up to about the width of the pointer pass halfway before the cooling fan comes on cools down fast. I am just not use to seeing a temp guage running over halfway. The BX1800 I have had for about 3yrs the temp on it runs under haft way on the guage. I felt the radiator and lines on the RTV and they are not that hot to the touch. Just wondering if I might have a defective guage.
