2003 Dodge Ram 1500 Q&A
2003 Dodge Ram 1500 Question: Check gauges light on at initial startup and temp gauge goes straight to hot?
I think that if the temp gauge goes to HOT on a cold start then there's a problem with the engine coolant temperature (ECT) system and the computer senses that and turns on the light. You need to get the truck checked out by a technician with a scanner to read diagnostic codes and data stored in the computer. A diagnostic check should cost no more than 1 hour labor time. The cost of repair depends on what's wrong. I suggest you find a Chrysler or Dodge specialist.
