HELP FAST!!!

[04G356MT]

OK I just bought a 04 G35 Coupe about a month ago with 40000 miles on it. I thought I was getting a great deal when i bought it but now im not so sure. My problem is im in the military and the car has to sit for 2-3 days without ever running and today on my way home as i was driving i looked down at the guages and i notice the temp gauge is reading really uberly hot so as soon as i see it i pull over and kill the car, i pop the hood nothing is leaking. nothing is hot, i check the fluid and its full and even its not too hot, the resivoir is fine, so i start the car back up and it still reads hot but drops back to normal very fast so im like ok, i hop in drive a few miles and it does it again, but this time i check something else and dont pull over i drive a little ways and the car drops back to normal droping a peg on the temp gauge about ever 30 sec, i myself think it may be the sending unit going bad, but i need other opinions and would like to know if this would be waranty work, I need help fast as this is my only car at the moment and need it working right

did this just start happening out of no where? it kinda sounds like u have an air pocket in the cooling system. are your fans coming on?

[04G356MT]

yea the fans come on... btw im the one that sent you the email yesterday...

[joe603]

purge your coolant system. If it still does it, it could be the sending unit, actual gauge, or thermostat.

Should be covered under warranty.

whats the easiest way to do it??

[cobrajet]

A sticky or slow responding thermostat will cause noticeable fluctuations in temp. It's happened to me before....

after the car gets hot let it cool completely down. like...a hour if not more. then take off the radiator cap and all the air should have come to the top by then...top of the fluid and you should be good if all it was, was an airpocket

Okay well after messing with it i found air in the lines so i filled it all and bled all the air, so its running right now, no jumpy gauges lol, but a new problem arose after that, ive learned where all my coolant went, on the driver backside of the motor is there a cooling line that runs next to the firewall or through it, cause i have a leaky hose back there and my coolant level is slowly dropping and i get nice little puffs of white smoke after the car has been running from under the hood, i can hear it dripping on the mani but i cant exactly see it from the top, so if anyone knows where i can find a diagram or something that would help i guess, ill prolly take it to the shop cause my sched with work just got hella busy, but any help would help

[infinititech1]

sounds like a heater hose to me.

infinitipartsusa.com has some diagrams
