Hi,

I'm just over 100 000 km on my Acadia and I want to change the antifreeze.

I searched for any good "HOWTO" article, but didn't find anything.

Does anyone has a good article for doing that ?

rbarrios wrote a very nice post for transmission oil change on this forum ... so I'm looking for something similar to learn how to correctly change my antifreeze.

Thanks,

Martin

I have not created one on the Lambdas yet-- as im not at the 5yr or 150,000 mile range. (Dexcool is now rated at 150K)

But If I was to do it today- with say 100,000 miles--- and knowing the system has no leaks
I would look into draining the system via the lower radiator hose.
I would not even bother flushing the system.

But with most coolant drained- and 100K--- I would probably even consider changing the thermostat.


I have not looked to see if theres a drain valve on the radiator on these vehicles.

There is No drain valve so yes the easiest way is to remove the lower hose from the stat and yes for the 40 bucks I would replace the T-Stat also.  it is REALLY easy.

If the coolant looks clean i would not flush it either..  otherwise just flush some distilled water through it

I will say-- that I believe on the DI engine vehicles (2009+)- the HPFP-- may be a little in the way.. as the HPFP sits right above the thermostat.

heres the sound deadening stuff over the HPFP- the thermostat assembly lies below it.

In the pic- you can see the throttle body
right by it- you can see that foam looking block-- that is covering the HPFP.
on a side note---(The high pressure side of the DI engine fuel lines are 1 use only--- so dont remove/loosen these unless youre really working on the HPFP- or youll be buying new expensive connections)...
but below this block is the thermostat.

You can see the shiny pipe that leads to the thermostat--- you can also see a clamp with a rubber hose attached to it.

below my 2010 engine pic  is the Thermostat on Ponchonuttys Outlook.


if you have trouble figuring out whats what..
compare the location of the transmission cable mount bracket in both pics.

That's nice.
My Acadia is a 2008 SLT

Nice post.

Thanks again. When I'll get the time to do this I'll give some news.

With young kids at home I'm always looking to get time Smiley

I have some maintenance to do on my acadia (transmission fluid, brake maintenance, coolant), I will go step by step Smiley

Is it necessary to change the thermostat housing in order to change the thermostat? Can one just buy a new thermostat and gasket and install in the old housing?

I would like to change my coolant.  I do not feel it should be necessary to flush it.  From what I have read here and elsewhere, all that should be needed is to remove the lower radiator hose.  I notice this is a cross flow radiator with vertical side tanks.  I tried removing the radiator cap, reaching a tube to the bottom of the radiator- I measured the depth and I seem to be at the bottom- and I syphoned out what I could.  It seems this should be removing as much as would be removed by removing the lower hose.  I only got about 1/2 gal out.  Does anyone know if what I am doing should be the same as removing the lower hose?  Does anyone know how much removing the lower hose should drain?  Does anyone know how a dealer would do a 5 year coolant change?  What would you suggest for a change.  It does not seem it should be expected to remove the thermostat to do a maintenance coolant change.
Thanks,
Tom

I have not done my traverse yet as the water pump crapped out and the dealer replaced it...twice!  However, on my avalanche, express, and cadillac sts, they use about 1.75 gallons with the lower hose removed.  I would suggest doing it that way.  1/2 gallon is not enough.

see pictures on this thread--- of how much coolant came out when I disconnected the lower radiator hose.

(Note- leaving the cap on the radiator- will suck out some of the coolant in the reservoir).

when I then removed the thermostat- more coolant came out

Thank you, I also do not believe 1/2 gallon is enough, thus my concern.  Great photos.  I have trouble estimating how much fluid is in your pan by just removing the lower hose, but would you say it is over 1 gallon?

What I do is get full strength dex cool and a gallon of distilled water.  mix them equally and you have 2 gallons for $17, as opposed pre mixed for $28.  I am going to guess and say it is going to take 1.5 gallons.  We shall see.

The cooling system capacity is about 12 quarts (3 gallons). This would include the radiator, hoses/tubing, engine, heater core (front and rear), and expansion reservoir (to the full cold mark).

Well, I "changed" the coolant.  I removed the lower radiator hose as suggested.  I doubt if I got a full 1 gallon to drain- the overflow tank was almost empty, so little from it.  Not what I call a good coolant change, but I am not interested in being more thorough by pulling front an rear heater hoses, thermostat, etc.  I will probably create more problems than I will solve.  Apparently the GM manual simply says drop the lower hose, so good enough for them, good enough for me.  It was not much work, so maybe I will do it next year also.
I did ask a former GM tech how their shop did it.  He said they put a vacuum machine on the radiator filler and suck it out.  It collapses the hoses, etc.  I do not see how this method would lift the coolant up and out the radiator, etc.  only the fluid in the hoses that can collapse.  In looking online, the only vacuum methods basically are used to refill, and by removing the air, they are already bled.  Sounds good for bleeding, and filling, but not for removing the old coolant.  Anyone familiar with this system?
Thanks,
Tom
