so we put a new water pump in this weekend. car runs great. nice and cool. no cel. but i drove 12 miles to work and it it only made it 1 bar above the 1/4 mark on the temp gauge. didnt make it to the normal opperating temp.

is this ok?? i know when i had my b16 civic it had a bigger rad and it NEVER made it to the 1/2 mark... but this just started happening with the new h20 pump for my ecotec. its an 04.
only thing i can think of is since the other one was leaking a bit, it wasnt doing its job, it would slowly heat up when parked. and this one is just fresh and healthy?

im goign to the track on friday and slightly concerned about this.

So its not heating up, your thermostat is stuck open then

agreed

I would say either the thermostat is stuck partially open or that there may still be air in the system throwing the temp sensor off a slight bit.

Well smart one air in the system isnt going to throw off the sensor, it will cause the car to overheat, shows how much you know about cars

Sounds like a thermostat issue. They're cheap, so whenever you're changing a water pump, it's always a good idea to change the thermostat. If you know someone with a handheld temperature gauge with an accurate readout (in degrees), check to see what the engine is running at. It should be somewhere between 195 and 205 (not sure what exactly the Eco is set to). If it's well below that (less than about 180), your engine will not operate properly. Not that it will run like crap, but engines are designed and the computers are calibrated for specific temperature ranges. Operating too far outside of those ranges causes it to run less efficiently.

Also, if the thermostat is stuck, it might not be an issue now, but when the cold weather comes along, it will run a lot cooler.

hrmm well it only does it in the morning when its cold out.. driving home from work when its 90+ outside, its right at 195.

Definitely sounds like a thermostat.
