Coolant tank by laserblue
Feb 23, 2009 (10:11 am)

I noticed this morning (engine cold) that my coolant in my tank is about 1 inch under the "cold fill level" line.
  I can't see anything on the ground, nothing is wet, my radiator doesn't seem to be leaking. Last time I used the truck my temperature gage reading was normal.
  Is it possible that the level comes low and then goes back to its normal level while driving? If so, I don't want to add some and then it's going to be over filled.

The coolant expands when it's heated up, the level will go up but not to normal level in the overflow tank in your case. You show check the level in the tank after using the vehicle. Top up the tank to just below the normal level on the tank with 50/50 mixed coolant when truck is hot.
 
Keep checking the level every day to make sure the coolant isn't disappearing. It's normal to have a small amount , couple of ounces of lost in 5-9 months depending on age and mileage of the vehicle. Your vehicle sounds like it's just operating normally but if the problem continues have GM check it for a possible leak in the cooling system.

I've just added 8 ounces of coolant in the "coolant tank". I remember that when the Equinox was new (24 may 2005) in the spring of 2007 I had to add some coolant and about the same quantity. Can the coolant disappear without having any leaks?
  If so, how and from where does it vanish?

If it's been 24 months between topping up the coolant tank ,and you only have to add 8 ounces that's normal. Yes the coolant can disappear without any signs of leaks. Sometimes it seeps by the head gasket and also can go through small hairline cracks not visible to the naked eye . This is just normal expansion and contraction of the metal the engine goes through during heating up and cooling.
 
 Example, Aluminum expands faster and farther than steel does at the same temperature, the 3.4 engine has a case Steel (case iron) block with Aluminum heads There's a better chance of tiny leaks due to the disimaliar rates of expansion of the two metals.
 Compare this to other GM engines that are completely made from Aluminum, like the 2.0 , 2.2 , 2.4, 3.6, 4.4, 4.6, 5.3, 6.2 and the 7.0 liter . These are better built engines.
 
 Hope this helps clear up your question.

Thank you very much rvoth. Your response will surely makes me sleep better at night.
I thought it could have been a busted head gasket because the engine head is a bit dirty but every engine I look at seems to be like that after a couple of years and replacing a head gasket could have cost me around 1,000$ or more.
  I appreciate your reply.... Thanks again.

So far the 3.4 doesn't have a problem with head gasket leaks. The service bulletins from GM don't mention any problems with the head gasket .
 I have an 2008 Equinox LT 3.4 liter ,had it for six months 6800 km and love this engine / transmission combination great for the city and good on the hwy. It has (220) ft/lb torque you can feel when starting from a stop and conservative amount of horsepower (185)
 . If you are looking for more speed/horsepower look at the SS version with the 3.6 (264) hp and 250 ft/lb of torque. It gets just a little less fuel mileage but much more power with a six speed transmission.
 I would purchase this vehicle again it has too many positives going for it.

I would also buy the same thing (Equinox).
Mine is a 2005 LT FWD and in the past I've owned 2 Blazers S-10 (1984) and (1994) and I love my Nox as much as my Blazers.

My Equinox is AWD we picked it up in Sept 08, every option available but we really enjoy the traction of AWD in snowy road conditions. Also the stability control works very well and we enjoy the seven speaker bose with XM radio. Nice feather the built in phone with the GPS system. The red beauty should last at least ten years i hope not nineteen years like my (90) GT Beretta has

Mine is only a FWD and it has "traction control". I'm driving on winter tires because starting this year they are mandatory and what a difference it makes. My Equinox is very good in the snow.
  We can get between 15 and 30 cm. (6 to 12 inches) when it's a good storm and no problems.
