HEY ALL,

BEEN HAVING SOME ISSUES WITH MY 2003 G35 THAT I BOUGHT A FEW MONTHS AGO. IT WAS OVERHEATING. SO I DID A FLUSH, BLEED THE SYSTEM AND CHANGED MY THERMOSTAT. EVERYTHING SEEMS FINE EXCEPT WHEN I HAVE THE AC ON AND I ILDE FOR A WHHILE IT STARTS TO GET HOT. BUT WHEN I ACCELERATE OR JUST GIVE IT SOME GAS IT STARTS TO GO BACK TO NORMAL. ALL THIS IS GETTING FRUSTERATING. AND I JUST WANT TO HAVE A CAR I CAN DRIVE AND I WANT TO MOD IT A LIL BUT ALL THIS NEEDS TO BE FIXED FIRST. ANYONE KNOW WHYB IT MIGHT BE DOING THIS. ANOTHER ISSUE I HAVE IS WHEN IM ON THE HIGHWAY AT SPEEDS ABOVE 65 IT SHAKES PRETTY ROUGH. ITS NOT THE MOTOR THO I TRIED PUTTING IT IN NEUTRAL AND IT STILL SHAKES. IT HA BEEN ALLIGNED AND BALANCED BUT STILL SHAKES. I HAVE STOCK CHROME RIMS.
ANY IMPUT IS MUCH APPRECIATED.
THANKS

 

I think I found your problem... it appears you left your Caps Lock key on when posting.

 

You need to try bleeding your radiator again. It often take close to an hour to get all the air out of your system. Shakes are caused by several things, out of balance or a tires that is really messed up...out of round or broken belts. Any quality tire shop should be able to pin point what's causing your shake issue. Not all tire balance systems are recalibrated like they're supposed to be so your tires could still be out of balance. Find a new tire shop...Gary

 

You have too much time in your hands

 

Time management is key.
