How do you replace a thermostat on a Buick rendezvous?

I had to pay a dealership $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.
Good Luck!
after i read this i had to say something.
I've changed thermostat on a 2002 Buick rendezvous before, it wasn't hard and you don't have to remove the exhaust crossover pipe.



I could not reach the back two bolts on the cross over manifold, so I took off the last piece of the air intake where the throttle position sensor is located. At that point I could get a wrench down there a slowly loosen the lower bolt enough to slide out the thermostat housing, and eventually the thermostat. It took me a couple of hours to complete a task that on any other car would take 30 minutes or so.

Where is the dimmer switch in 2005?

Not sure if this helps or not but on a 2005 Toyota Sienna LE, the dash-light dimmer switch is actually the trip odometer reset switch. Turning the trip odometer reset switch left or right controls the dash-light levels. Had it not been for the factory manual, and Google, I would have never known this.

DOT 3 from an unopened can. If you look on the cap for the master cylinder reservoir you will see the correct fluid listed.

Brake fluid should be changed at least every 50,000 miles.

Why would the trunk be leaking on a Buick Park Avenue?

I just bought a 92 PA, and THEN looked below the spare tire cover..Surprise!!! 3 inches of water. There seems to be some water trapped inside the trunk lid seal, so I'm guessing it is entering uphill someplace, and running around the seal and exiting through one of the weep holes the in the seal.. Internet search also indicated it could be the power antenna (there was an alert about leaking loose power antennas), since I did notice mine was loose. On my 94 PA Ultra it was the rubber seal around the rear light assembly. Both left and right side. You have to remove the lights completely, clean and apply a silicon sealer/atv, Careful prying off the retainers from the plastic pins that hold the lights in place: they brake easily. UPDATE: Found the leak, just like the last poster said, between the tail light gaskets and the rear. A little sealant and all is well. Thanks! so was mine. Pull back the carpet on the rear trunk side - if there is water in the holes where the bulb wiring is, you have the leak 1993 Park avenue trunk leak is generally caused by dried rubber gasket between taillight assembly and trunk body. Trunk lid gasket is usually NOT source of leak 1. Pull interior carpet and trunk liner. 2.remove 10-12 10mm nuts 3. you may disconnect wiring now or easier after you gently pry the whole assembly about 8-12 inches away from car. Disconnect 2 taillight connectors and two license plate bulbs. 4. Buy new or gently remove two oval-rectangular gaskets (this is VERY MESSY - they use a 3M sealer). 5. Use silicon sealant between gasket and taillight AND between gasket and trunk body. 6. replace assembly onto trunk with nuts finger tight.(do not tighten) 7. replace wiring connectors. 8. wait 30 min. tighten some more. wait 2 hrs. snug up nuts. do not overtighten - it will distort the gaskets Surprise: I'm surprised you had standing water in the spare tire well, I thought there was supposed to be a "Weep Hole" to let that water out.
