So I have a 1998 LS400 with 170,000 miles on it. It has been babied and garaged. It is in fantastic shape. One morning this week I started the car, drove about a mile and noticed that the temperature gauge was just under the red line. It normally hangs out just under the halfway mark. I tuned around and drove home as not wanting to run it too hot. Here's what i checked on to determine the issue. Water pump, timing belt, thermostat, all radiator hoses and new coolant was just done 12,000 miles ago. This check out normal. Then I thought that it might be the sensor/sending unit indicating the wrong temperature to display on the gauge. I was going to just buy a new one and change it out, but then I thought of hooking up my OBDII scan tool to check the engine temperature. Sure enough the engine temperature read normal through the real-time scan tool. Here's my logic. If the scan tool shows the correct temperature as read from the ecm computer, it must be getting the temperature sent to it from the sensor correctly which means that there isn't a reason to change out the temperature sensor as a possible fix. I believe that I can rule it out. I think that only leaves me the instrument gauge itself that could be the culprit in this issue. Also, I think that this is the part I need. CLICK-HERE If this is the issue, would it be better to just buy the gauge and change it out or send the instrument cluster in somewhere to be rebuilt? Also, occasionally the tach sticks at zero so a good slap on the top of the dashboard above the gauge fixes it. Maybe a rebuild of the instrument cluster would fix this too. Please help me figure out this dilemma. I try to keep everything on the car working at 100% so even if the car isn't running hot, I want the gauge to report the correct temperature.
I need help figuring out what is wrong with my gauge cluster. My speedo wasn't working so I took apart and tried getting it recalibrated. I put it back in and now none of the gauges or back lighting work. I had another cluster available and I installed it just to find out that it does the same thing as well. Only things that work are the high beam symbol, air bag, door ajar, and turn signals. Any ideas on how to find the problem and fix it?
