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).
Remove the air inlet duct tube. Remove the heat shield from the exhaust and move it out of the way. Unbolt the crossover exhaust pipe bolts from the from the front exhaust pipes move it out of the way. Unbolt the thermostat housing pipe and remove the thermostat. Installation is reverse.
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.
Thermostat on 1999 ventureI just had to have mine changed on my 1997 Venture. You have to remove the throttle assembly which is a big job. I had my mechanic do it and it cost $170. The part was $20, labor $150. The dealer and one other mechanic I called wanted $300 to change it :( I just did my own on my '99 venture. Part cost me 13 bucks. If you are handy with tools, it's not that difficult at all. Takes a little time, but it's not that hard to do. hardest time I had was the back bolt on the tstat housing. I have large hands, and you need a 13mm wrench from underneath the exhaust. Tight squeeze and not much turning room. Fortunately, you don't have to remove it completely.
I have had a problem with mine. I have a 1997 Venture. I was told that it is very hard to get to and can take a mechanic around two hours to take out. Unfortunately, my thermostat has a bolt that is stuck and will not budge. The mechanic would have to go about getting it out another way. There was a 50/50 chance that it would come out without ruining a part that would cost $600 to replace.
I would have to say, change the thermostat in it.
if you can replace it yourself but do it right look on the web for info vids
There is no need to remove the timing belt to change the thermostat.
Hi, The thermostat is located on the driver side of the engine, just below and in front of the throttle body. These are a real pain to change because of the extra parts that have to be removed to get to the thermostat housing. I have included a link that shows actual pictures of the location.
you need to remove air filter and some of the exhaust pipe before u can get at it.
did you change the thermostat
The thermostat is located under the thermostat housing, very near the throttle body, on the driver (left) side of the engine. Just follow the upper radiator hose and it will take you right there, but these things are a real pain to change. Good luck
Follow the top radiator hose back to the engine. The thermostat is behind the housing that connects the top hose to the engine block.
look where the air intake goes to, on the driver side of the block If you have the 2.4L DOHC 4cyl. the thermostat is attached to the water pump, which is located under the exhaust manifold on the side of the engine facing the fire wall. you will have to pull the exhaust manifold in order to change it
follow top radiator hose to the end, there is the thermostat in housing on end of hose. on 3.1 v6 it is under exhaust manifold! it looks like it would be hard to change but it can be done.
It is located under your throttle body and when i change it i remove the exhaust line to reach it. Loosen bottom bolt and remove top this will allow it to just pull off and lay downward without falling off makes easier when reinstalling. Follow your top radiator hose on driver side to thermostat housing.
