The thermostat may be stuck open, I just got done replacing my thermostat and it stays just on or above the cold line. It may also depend on the rating for the thermostat for when it opens at certain degree's.

That used to happen in my truck. It was always running super cold according to the temp gauge. However, i was running my truck a little hard one day and blew my water pump (that's always fun) and after i replaced it my temp gauge went back to normal. When it runs now the needle sticks around the middle of the gauge. The only thing that i could suggest other than that because your water pump is probably fine... is to check ur thermostat.

Is the engine actually getting hot? Basically what I'm getting here is you need to determine if your gauge is reading wrong of the engine is actually not warming up.

If the OHC is using the computer's temp sensor as opposed to the gauge sensor, which seems likely, then I think your t-stat is still screwed up. The gauge and computer use two different temperature sensors. If the gauge and the computer's readings are both low, then you can rule out a sensor problem. It should be running 180-195.

Well, it did exactly as it's labeled... failed safe... Sucks but at least it's simple.
