You take the trottle body lose and use a stub wrench to get the bottom bolt. The bottom hole in the gooseneck housing is really a slot, so just loosen the bottom bolt to allow enough clearance to get the housing by the thermostat.

I found removing the bottom bolt made it earier easier to remove the housing. You will need a 10mm stubby wrench(stubby ratchet wrench even better) to get to the bottom bolt,as well as a pry bar to pry the heat shield away from the thermostat housing to give you a little more clearance to get it past the thermostat, this made the job ALOT easier. You should also get yourself a throttle body gasket while your at the parts counter because it will probably break when you remove the TB (mine did).

The thermostat on a 2004 Chevy Venture is changed by draining the radiator, removing the upper radiator hose, and unbolting the thermostat housing. The old thermostat and gasket can then be removed and replaced.

To change the muffler or exhaust in a Chevy Venture, jack up the vehicle and locate the muffler. Spray penetrating oil on the nuts and loosen muffler clamps. Replace with new.

With great difficulty. If you have nimble fingers and a good set of tools, you may be able to remove the two bolts that hold the thermostat housing without removing the exhaust pipe.

On the 3.4 V-6 Chevy Malibu the thermostat is located at the rear of the engine. The exhaust cross over pipe that goes between the exhaust manifolds makes the thermostat housing hard to access. The easiest way to change this thermostat is to first remove the exhaust shield and exhaust cross over pipe, then the t-stat can easily be changed. After changing the thermostat, be sure to bleed the air from the system, look for bleeder screws and run heater until air blows warm.
