Default temp?

with a scan tool on a cool night my car was idling about 193 degrees or so.
I have a 180 thermostat and an intense pcm programed to it now while driving my gauge reads right under 200.
I recently replaced the water pump and there was no change so I cant figure out what it could be?

Ok then.

You were moving. How fast?
Had you sat still for a while or done some recent spirited driving?

193 isn't overly hot and you can't expect the car will stay exactly at 180 due to t stat and pcm.

Using an 180 degree thermostat doesn't mean the engine will operate at that temperature. It'* just the temperature that coolant begins to flow though the radiator.

Thermostats do not regulate coolant temperature. Engine designs (primarily radiator and oil capacity ) and operating conditions do.

While a scan tool is a great tool to have, try to avoid the natural tendancy to over-analyze things you see on it during normal driving. Unless there is a reason for you to suspect that you have a problem, your car will let you know.

Anyone ever noticed the difference between the standard dash cluster and the SSE/SSEi cluster in regards to temp gauges....I have.

SSE/SSEi are spread out much more..therefore you really notice any fluctuations and differences in temp. Like the standard clusters...my truck has a tighter gauge and you wouldn't notice a 10 degree difference very easily.

It may be that we are over thinking this one and it'* running just fine.
