Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2000 Pontiac Grand Am Owner Comments

problem #1

Jul 102014

Grand Am SE V6

  • Automatic transmission
  • 126,000 miles


Recently had to replace the RADIATOR ... ( $360 dollar job - plus radiator cost at the mechanic ) I have replaced everything on this 2000 GA SE1 coolant system except intake manifolds and hoses ...Car was losing or boiling coolant and needing to be replaced 2-3 times a week ... replaced the filter and thermostat issue still remained ... Recently the radiator cracked on the way to the Auto parts store to get a EC sensor, wanting to try that had that plus the radiator replaced ...

CAR gets really ( abnormally ) hot still, however, it is no longer needed that I turn on the AC to cool the car once it goes 2-3 lines over 200 ... When the car gets to 3 lines it appears that it cools itself. However. once it gets back down to 200 or a line over it heats up again till it cools off again and it's constantly fighting to heat and cool and heat and cool ... etc etc ... ... It doesn't appear that the FANS do enough cooling ( on low ) to keep the car from getting to that HOT point. Also when switching gears from reverse to drive ... the CAR seems to fight to get into gear (when the ENGINE is EXTREMELY hot - after driving for some time).

Mechanic checked all fuses and relays, they all seem to be testing fine ... There also appears not to be any leaks, however, the CAR gets VERY hot to the touch and you can feel the heat coming off the car when at a light etc etc. The water pump and serpentine belt (not related - as well as other pulleys) have been changed ... I am REALLY at a loss as to what is causing this to continue to happen ... The front end of the car ( chasis ETC ) is loose although it has no obstructions ... However I don't think that is related to the issue because I see other folks are having the same overheating issue ...

I have had the COOLANT system flushed and bleed at the mechanic several times already, in fact, when they replaced the radiator and all the coolant was removed from the car they filled it and bleed it with the screw till nothing but coolant was coming out of the bleeder valve. Also I think the reason we are losing coolant so often is the fact that the car is getting to HOT that it is boiling and evaporating ... Also the car has problems shifting into gear when she is very hot and has been for some time ... although the ECS and is doing its job turning the fans on and cooling the car and the temp sensor has come down to 200 or 1-2 lines above before it turns off and starts getting hot again ... EXAMPLE; trying to park the car put the car into reverse and back in, when you put it back in drive to move forward she won't shift fully into gear and only after a moment or so of pressing the gas and letting her slowly move forward will she then pop into gear ...

The air filter was changed on the car ( not in relation to the overheating issue )
