'05 Ram 2500 temp gauge

rett81 · 06-15-2009, 06:56 AM

I have an '05 5.9 that the temp gauge acts weird. It's pegged low until a load is on the truck for a minute then pegs high. The thermostat and the sending unit have been replaced to no avail. The engine is not really hot it just indicates that it is when loaded i.e. pulling a 9% grade. Any ideas?
