2005 Buick Century. Heater core pluged up,very little heat. Had to pry tabs on radiator cap to remove. Found hole half closed with a gray goop, like a stopleak subtance.No radiator drain plug. removed lower hose to drain coolant. Filled with retrived airconditioner water and raditor cleaner ( detergent). run engine for 20 min.Drained cleaner. 4 refills an drains later water was clear. After flush heater produced hot air. Installed green prestone 5 yr. antifreez,1 pint soluable oil which is aluminum compatable. This was done at end of warenty,36000 miles. Now at 42000 miles, no goop an water pump is silent and plenty of heat from heater.Before changing antifreeze there were no leaks,only a squeeking water pump at cold start,and partially pluged heater core. Have had no problems since. Have i done anything wrong? Comments please, Thanks Jack Hout

I think you answered your own question. When you said " Have had no problems since" says it all. Everything you did makes sense and I don't forsee any problems based upon your description...I'm curious though: tell us about the water soluble oil you used.

Got rid of the culprit vehicle (2000 Olds Silhouette) a year ago when the replaced gasket started leaking.

Got my $400 check yesterday. Too bad I had to replace the gasket again 3 days after the cutoff for claims.

442dude, I used a product called Trimsol. Soluable oil added to water sumps for machining metals in drilling boring an turning applications.To be on safe side 6 0z. of straight trimsol to 17 QT systems is fine, more than that, coolant becomes a little sticky. If was sticky still no problems. I have used this since 1969 with no radiator or heater core problems. Water pumps lasted up to 145000 miles or longer.1969 dodge slant 6. Hoses lasted longer also. At least they didn't fail any sooner than normal,what ever that is.

#7 of 15 engine coolant drain plug by hout

442dude,Unable to locate a coolant drain plug on 2005 Buick Century 3.1 engine.If there is one,where is it? Constant flushing untill clear is fine, only to be able to install a little over 3 Qts of undiluted coolant and system is full. Never seen engine without coolant drain plug. So i remove lower radiator hose,drain. Add undiluted coolant,take a drive and check consentration and repeat procedure. This does take some time. Ought to be a less time consuming procedure. At least GM was thinking some, 2 air blead valves solve air pockets. Jack

Hi Jack,
 
Sorry I didn't see your post sooner - we traded in our Venture so I don't look around here as much as I used to...
 
Anyway...according to the FSM:
 
They don't show a picture of the drain but they mention that there is one on the radiator...I recently drained and refilled my Vue and the drain plug looked more like a screw than the drains like we're used to seeing - on the passenger side of the radiator, and on the SIDE of it, very different than what I'm used to seeing - you actually use a screwdriver to open it and the coolant either comes out full blast and splashes all over the place or just a trickle (Dexcool tastes pretty good by the way although I wouldn't recommend drinking it - and it takes a lot of turns to get it open...it also takes a lot of finesse to get it closed.
 
I'll stop by more often - let me know how you do...

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
