So, this may be covered somewhere, although a search didn't find it.
I recently bought a one-owner, beautifully maintained 99 Suburban C1500. I've replaced a few small parts (bulbs, stereo, like that), including the coolant temp sensor in the block and the thermostat. Interestingly, the temp gauge still won't go over about 1/4 up the scale and, more worrying, the lower rad hose remains comfortably touchable even after driving several miles. The engine has not shown any signs of being excessively hot at any time since I've had it (about 6 weeks) and no warning lights have come on while driving. I'm out of ideas; does anyone have any suggestions as to what to look at next?
