hi all i have a problem with my temp gauge it takes a long time to reach full temp i have changed the temp sensor its made no difference i was thinking thermostat but heres where it gets tricky because if the thermostat was faulty and stuck in the open possition i would expect the oil temp to be as slow rising as the water temp ? this is not the case the oil temp rises well before the water temp gauge begins to move so am i wright in thinking that all is well other than the actual water temp gauge reading wrong every car i have had as worked the opposite of this ie water temp starts to rise followed a few mins later by the oil temp begining to rise any ideas would be very welcome also for got to mention the fuel gauge seems eratic one minute its reading just below half a tank the next it is reading just above the red area do you think this could be linked t the temp gauge problem
