The thermostat will be at the end of your upper radiator hose. The neck that the hose bolts to needs to be unbolted from the engine - that's the thermostat housing. Should be three 10mm bolts, as well as some hoses that you may need to disconnect.
If you're replacing your thermostat, come prepared. You'll need to scrape the old gasket material on and apply a new gasket. Also, pay attention to how you remove your old thermostat and be sure to put the new one in with the same orientation.
drain coolant until its below the thermostat.then remove two thermostat housing bolts.remove thermostat housing and thermostat.make note position of thermostat before removing it.then carefully clean all old gasket material from thermostat housing and cylinder block you can buy can gasket remover at any auto parts stores.buy new thermostat gasket.if you have the paper type you need to buy RTV SILICONE to help seal gasket if you have rubber type gasket you dont need RTV SILICONE.make sure both surfaces are clean.then install new thermostat and new gasket.if you have paper type gasket apply thin 1/16 coat RTV SILICONE both sides thermostat gasket.then install gasket to thermostat housing then install housing to cylinder block first make sure new thermostat in place before installing thermostat housing. let RTV silicone sit up about hour before adding coolant.IF THERMOSTAT HAS THE O RING SEAL DONT NEED RTV SILICONE AND THE PAPER GASKET.
if your motor is the 3.4 then you dont have to worry bout the exst pipe since the thermostat housing has a slotted hole were the pipe is, but beware that those two 10mm bolts are somtimz very tight so youll probly need little extra leverage, otherwise its simple
To replace a thermostat, you will need at least:
1. A new thermostat
2. Needle-nosed pliers.
Depending on the thermostat and location in your home, you may need more. Make sure the new thermostat you are using to replace the old one with is compatible to your 110-volt housing circuitry. Always turn off the electrical power to the home thermostat at the power panel or circuit breaker box.-------------------------------------------------------------------------- carbrain c168 scanner
The housing is held on my two bolts and utilizes an "O" ring rather than a gasket like many of the thermostat housings. So you will need to check that "O" ring for cracking and damage. It's located on the right hand side of the engine under the intake housing which needs to come out to replace this thermostat. If you follow the top hose of the radiator it leads right to your thermostat housing.
You'll need to remove the upper radiator hose from the thermostat housing. Unbolt the 2 bolts holding the thermostat to the intake manifold and remove the thermostat housing and thermostat. Clean both mating surfaces and install the new thermostat with a new gasket, reinstall the radiator hose, fill with anti-freeze and check for leaks.
You need talking with the parts guy at the GM dealer You need the "new" style
thermostat housing to be able to change just the thermostat. So I
ordered a new thermostat housing assembly. Here is what I got, a new
aluminum two piece housing and thermostat. Hopefully tomorrow I can get
this car back on the road and out of my shop.
Hello, follow the upper radiator hose to the thermostat housing, position a pan under the car to catch loss coolant. Remove the the housing screws move the housing out the way and remove the thermostat. Before installing the new thermostat clean around the housing very carefully. Install new thermostat, gasket-if needed, and thermostat housing tightn screws, add coolant.
Where the upper radiator hose attaches to the engine is the thermostat housing. Remove the hose from the housing. Remove the housing, the thermostat will come out with the housing. Be careful to orient the new thermostat exactly the same as the old. If the new thermostat is put in backwards the car will overheat.
Hope this is helpful.
