If it's the same as a 1996 Buick Somerset, then... WHEN THE ENGINE IS OFF AND COOL, remove the radiator cap. It's actually not on the radiator. Follow the top hose off the radiator to the engine block. Remove that cap. It should be full of antifreeze and or water and you may not see the thermostat, but it's there. Stick your finger in the throat and you'll feel the top of the thermostat. You can pull it straight out. It's 3 or 4 inches long, total.

Actually it's not the same as that vehicle. It's located on the driver side under the air intake/mass air flow housing (which has to be removed) and there are 2 bolts holding its housing in place. The top bolt isn't that bad to get to but the bottom, well it can be a bit tricky getting it back in (you have to use tips of your finger to get it started and hopefully you have somewhat small hands as it's quite a tight fit. I've replaced mine with not much trouble but plan on spending about 2 hours or so on it since you'll have to remove several things just to get to it and I'd suggest you take pictures or even better yet a video of the area you're working on if you've not worked on this vehicle before and/or don't know a lot about what you're doing.
The thermostat on a 1991 Buick Skylark is located near the engine. To find the thermostat, follow the top radiator hose directly to the thermostat.
Well it depends on the type of engine you have, but that only has to do with the thermostat's location. The Haynes GM manual #38025 has instructions on how to change the thermostat in section 3-3. Amazon has copies of it dirt cheap.
I have a 93 buick skylark and i cant find the thermostat on the da*n thing.. can anyone explain to me on how to change it??? Follow the hose to the top of the engine where it ends. The thermostat is under the thing where the hose is attached. There are two bolts holding it down. Also, get a Chilton's or Haynes manual from Amazon. They have the procedure and the books are cheap.
The thermostat on 4 cylinder, 2.3L Buick Skylark is on the bottom of the water pump. Remove the metal water line connected to the bottom of the water pump to find it. Remember the new O-ring with the new thermostat.
sounds like yours is broken.1 thermostat and 1 o-ring or gasket
From a small pipe connected from the top of the engine to a radiator hose.
oops check with a buick mechanic,
will the fenders from a 1971 Buick Skylark Custom fit a 1972 Buick Skylark?
If your car is over heating you may want to check your thermostat and replace it may solve your over heating problems
Buick Skylark was created in 1953.
Around 40psi. Maybe a little less.
Do you mean "change THE transmission" or "Change the transmission FLUID"? Big difference there....
