Hey guys it seems lately I have been having issues with my 07 m35. the latest of the problems is over heating I took it to autozone to see why my check engine line was on, they diagnosed it and told me it was the thermostat, replaced that but it was leaking all my coolant out found out it was the waterpump. replaced that and it is still overheating, the check engine light is off, but it is overheating. On top of that my power steering is bubbling out the storage unit. I have no idea on why it is over heating like it is doing, anybody have any ideas on what the issues maybe?

Shong,
Very interesting about the P/S spillover.
Is the P/S spillover occurring while engine is cold before it overheats?
First thing I would have checked is to see that the serpentine belt is on the pulleys correctly.
After confirming/correcting that issue, I would have the coolant system properly bled to remove trapped air in the engine!

Steve,
The power steering boiling over while the car is running, I did notice that the belts were winding never made that noise until yesterday, I didn't mention that I had a new alternator put on, so do you think the belts are on to tight? I just read that the system has to be bled correctly, also I did by the thermostat from autozone that might have something to do with it as well. I will try to bleed the system first if that don't work I will order a new thermostat. I will keep you guys posted.
