2006 Pontiac Grand Prix Gxp Thermostat Removal

[sschwaeble93]

What has to be removed in order to replace the thermostat in a 2006 Pontiac Grand Prix Gxp?? Looks very tight where the housing is placed.

Can anyone tell me the best way to remove the old thermostat housing and thermostat???? Do the headers need to come off?? Any help greatly appreciated.

In the interest of time yea take the front manifold off that way you have room to do everything however I highly recommend some pb blaster on the manifold bolts the night before you attempt taking them off have extra bolts and studs on standby
