442dude, I have found no drain plugs of any kind on 2005 Buick Century pertaining to coolant. Benifits to removing Dex-cool ! Installed Peak around first of June. This was complete flush with flush kit from prestone installed per instructions. I found it difficult removing thermostat housing bolts. Removed heat shroud. Per instructions of Haynes Repair Manual coolant was removed and new insalled. No mention of removing heat shroud in repair manual. On 6/20/09 radiator cooling fans came on first time since October of 2005. Heat gage was normal, Engine had idled for about 2 minutes, 88 outside Temp. I feel that this was a normal condition, Air had been turned on before arriving home. So i think Dex-cool with what seems to be some kind of sealer in it kept the coolant sensor from working properly. Also heater works properly. Coolant must be kept clean so sensors can do there job and heater cores back flushed to remove foreign material. I agree with coolant Mfg's saying replaceing coolant every 2 Yr's. Point is you can use any brand of coolant you want ase long as you keep it clean. I am sure there are some no-no's. Jack

There is mostlly likely a drain on the bottom of the radiator if you can't find anything on the side tanks. On my leSabre there's a hole up through the air dam the goes to a pair of prongs that are the screw. I have read a certain size socket fits on those and you can turn them on the end of a socket wrench without removing the air dam. I just take off the lower radiator hose like you did.
Also don't know which motor you have but there are supposed to be two small drains on a 3800. I never could see them while under the motor. I also have read that the knock sensors are removed to allow a block drain.

2005 Buick Century custom has a 3.1 V-6. Very hard to see, without lift any sort of fittings for removal of coolant. Jack
#13 of 15 Replacing DexCool
Jul 17, 2009 (8:32 pm)
I have a 1996 Olds 88. I am thinking about replacing the DexCool coolant in it. I've heard that this coolant causes a lot of problems with leakage and corrosion, particularly with the intake manifold.
Do you recommend that I flush the DexCool out?
Should I do a "power flush"?
And what coolant should I use instead of DexCool?

I just replaced the intake manifold gaskets in my 1996 chevy c1500 5.7L about two months ago.The water pump was right behind that. I was aware that there were lawsuits in other states,but not in WA. Is there any way to re coop my losses on this one?

I replaced the dexcool with the green about two months ago after learning that my intake manifold gaskets were leaking. Then a month later,the water pump. They say its ok to do,but have to get ALL the dexcrap out!! I had the work done at a shop. Dont know what to tell you on the power flush. Google "dexcool issues" and and read up on it and you should be convinced to make the switch to green.
