95 lt1 coolant temp sensor
Hi all, quick question. I replaced the water pump in my 95 last week, I reused the coolant temp sensor in the front of the water pump. Now the temp is showing 182 under normal operation, maybe gets up to 200 while at a stop light then right back down when I start to move. I replaced the radiator in June of 2015 with a stock type radiator ( not a high performance one) and the temps would stay at 194 then under normal operation. I replaced the thermostat yesterday thinking maybe the old one was bad. Could replacing the water pump cause the temps to fall like this or does it sound like the sensor is going south?
Thanks in advance for any insight.

Not that is working better, it just seems the temps are a bit low from what they had been over the past four years. Normal operation usually stayed in the mid 190's now it's in the low 180's. SHOULD a new pump lower temps by ten degrees?

Might be the weather as well, Id be content with that as it will start to rise soon enough.

If you've replaced the t'stat with correct, you're confident in the CTS performance and you believe the system to be bled properly I believe you move on, enjoy and concentrate less on the constant monitoring of what seems to be a cooling system that's working.
How many miles since the water pump replacement? You did the pump and how many miles later the t'stat? You're confident in the bleed?

The CTS, it's original, so I'll just keep an eye on the system and quit worrying so much. Thanks for all the replies.
