Dashboard Problems

[oscarmanny]

I drive a 90 LS400 owned for about a month. The RPM Gauge has never worked since I've owned the car . My Temperature Gauge bounces up and down it mostly stays up with any speed bump or the bass of my stereo. I dont know what to do, I've had it checked at a shop. The water pump, thermostat, and the radiator seem to be working fine. The car has alot of problems but the temperature gauge bothers me the most. Someone please help me!!

The problem may not be in the cooling system. It may very well be in the instrument cluster. On the older LS models (mine included), the needles start to go after a while. My speedo and tach both stick initially in the 0 position, but then break free after a tap on the dash or after driving a mile or two.

You could put in a new third party coolant temp sensor and gauge or replace your cluster w/ one from a wrecked car.
