hi guys
my water temp gauge is playing up ,start the engine drive off and it water temp comes up as it should but it will then drop back down to the cool area (blue section) then it will rise again .i was thinking it was the temp sensor but after plugging in gap tool i watched the water temp rise on the live data so im not sure now .could it be the thermostat ?.any help much appreciated
