I recently bought a new/used NX2K. I love that car:D Anyways when I drive the car Ive noticed that the temp guage never goes up as far as it shood and it comed up to temp relly fast. It never gets any hotter or cooler weather Im just cruizing ro driving relly hard so I dont think its a bad thing. Does anybody know what mite cause this? Im stumped I swapped the temp sender off my sentra with the same results. Please help Dan.

Thermostat

1. Thermostat
2. Radiator cap
3. Water pump

Hey thanks guys. I never even thought of the thermostat. The rad cap is 0.9 and it looks to be stock watter pump. Ill look in to that a bit more. Thank you for putting my mind to rest on this matter. Now I can go back to acting crazy in stead of being crazy.
