why when my car is sitting at a stop or moving slowly, my water temp starts to go up???

 

low coolant level? fan not turning on? thermostat? water pump not working? its kind of a vague question, a huge variety of problems.

 

okay well my fan turns on and the coolant level is perfect. my buddy said maybe thermostat. im hoping its not the water pump.

 

change the thermostat, if that doesn't fix it, change the water pump. if that doesn't fix it, chances are you've got a blown head gasket.

 

most likely thermo..

seriously, you need to post more info. did you do ANY research before posting? did you troubleshoot anything in your coolant system yet? i hope you get this fixed, but these threads with almost no info on problems are annoying as s***...

 

Also make sure your coolant system is bled properly, air bubbles in the lines might cause this issue also.

Pop the cap off, let the car warm up, let the fan cycle twice, make sure to turn on your heater full blast, and watch to se if any air bubbles come out.

You can also test the thermostat by putting it in a pot of boiling water, when you take it out, it should close slowly. However if the thermo was stuck shut, the car would overheat no matter if you were sitting still or driving, as the coolant can't get to the motor because the thermostat is stuck closed.

 

do a leak down test first to rule out the headgasket.
