(see Figure 7)

When adding coolant, it is important that you use GM Goodwrench DEX-COOL® (orange colored, silicate free) coolant meeting GM specifications. On these vehicles, if silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner; at 30,000 milee or 24 months.
  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant to a level below the thermostat.
  3. Unfasten the cover-to-outlet pipe bolt, which is accessible through the exhaust manifold runners.

How do I replace the thermostat? Is it something I can do my self with no car repair experience?


The short answer is yes you can do this repair with little repair experience. Locate the upper radiator hose and follow it back to the block, assuming you have already gone and picked up the new thermostat and a seal and form-a-gasket. Once you locate this point on the engine where the upper radiator hose connects to the block you need to remove the radiator hose from the engine. After removing the hose, get the proper sized socket to remove the 2 to 3 retaining bolts that hold this mount to the engine and remove it. Under that piece you will find the thermostat. Take it out, paying attention to the direction the old thermostat is installed, clean off the old seal and sealing compound. Place the new thermostat in place then apply a thin bead of Form-A-Gasket to the cover piece and carefully lay the seal in place on that, make sure you line up the mounting holes. Place a bead of Form-A-Gasket on the motor side and then replace the thermostat cover and radiator hose mount. Once you have it tightened down securely re-attach the hose and fill the radiator. Test driver the vehicle after letting everything sit for about 30 minutes if you find a leak tighten the bolts near the leak to seal it up and the job is finished. Should take about an hour with drying time and test driving.

Where is the thermostat located at


Remove the plastic engine cover, find the top radiator hose and follow it to the motor. Where the radiator connects to the motor, is the thermostat housing. Just remove the hose and then the bolt holding the housing on and change the thermostat. dont forget to scrape the old gasket off of both the housing and the motor to get a good seal.

Some kind of water flow or thermostat box is broke


It is the water inlet housing. It has a pipe screwed to it that goes under the lower intake. You can unbolt the pipe and change the housing but the easiest way to do it is to remove the upper intake. I was in a carquest store the other day and they had these housings in stock.

Changing thermostat in 2004 Rendezvous


The dealership will charge around $450 to change the thermostat on the 3.4L engine.
You have to remove the crossover exhaust manifold. Once that is out of the way, the thermostat itself is easy. Before the manifold is removed, I could only touch one of the two bolts holding the thermostat housing in place, much less get a wrench on it.

If your engine is the 3.4L then the instructions below will work:

REMOVAL: - Remove the air cleaner and duct assembly. - Drain the coolant until the coolant level is below the thermostat. - Remove the crossover exhaust pipe. - Remove the radiator hose from the thermostat housing. - Remove the thermostat housing bolts and clean any sealer from the bolt threads.

- Remove the thermostat housing and gasket. - Remove the thermostat. - Clean the mating surfaces.

(IMAGE: The removal and installation of the thermostat) 0b61938.jpg

INSTALLATION: - Install the thermostat.Install the thermostat housing and gasket.

NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

- Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm). - Install the radiator hose to the thermostat housing.Install the crossover exhaust pipe. - Install the air cleaner and duct assembly. - Fill the cooling system.

Hope this helps, happy holidays :)

Thermostat location


The thermostat is in a difficult position. Follow the upper radiator hose and it leads into the block under the throttle body. 
Remove the air filter assembly and you'll c what is the exhaust manifold crossover pipe right in front of the thermostat housing.
 NICE, it gives you very little room to remove the 2 bolts to the housing and once u remove those then you'll find you have the thermostat housing loose but because of that darn exhaust manifold crossover pipe u don't have enough room to take the thermostat housing out to change the stinking thermostat. 
So from what you can see, you have to remove the heat shield which is cased around the exhaust manifold crossover pipe and if you still can't get enough room to remove the thermostat, (which you amy find out)then you'll have to remove the crossover pipe as well just to change the thermostat. 
If you have to remove the crossover pipe then their are 2 bolts on both ends of the pipe leading into the manifolds. But then the tough parts done and once u switch the thermostat over and ATTENTION:remove any old gasket material and put a new gasket in it's place then installation is reverse of removal. 
Good luck and hope this helps,
