DENSO or AC Delco Spark Plugs for a Northstar?

Keep an eye on the level in the reservoir. You want about two inches of air space when the engine is cold.

You might find that your "heavy" mixture of antifreeze does not conduct heat as well as the desired 50/50 mix. Easy enough to adjust by draining and refilling a few times with a 50/50 mix.

At this point I think I would invest in a refractometer to get the mixture correct.

I just bought the bars leaks, $1.99 at pep-boys, but, is it safe to pour this in a 2000 deville?
it says Radiator stop leak and conditioner .

thanks.

[JimD]

Do not put any liquid Bar's Leaks products in there.

Use the Bar's Leaks Golden Seal radiator stop leak powder (product G12BP on the bottom left hand corner of the package) which is usually available at Wal-Mart or the same material in a package of big old tablets.

And put the powder or tablet in a hose, NOT the reservoir.

The tabs product code is HDC.

Is this the one?













And one last question, in my dashboard, the Check cooland keeps coming up, actually, it never dissapeared.. what can it be? the coolant sensor maybe?
cause it is actually a little higher than the level..


greetings...

Ger.

Yes. Put the contents of two of those tubes in one of the hoses.

If the coolant level is within two inches of the top of the reservoir, the level sensor in the reservoir has failed OR the chassis connector on the bottom is not seated properly.

If you happen to use the GM supplement tablets, DO NOT CRUSH, but add whole to the LOWER radiator hose.

I crushed the tabs added to the top hose (it was easier and I was lazy).

Fouled the T-stat all to hell and the rest settled in the left side radiator tank. Over heated in 15 minutes. My radiator guy laughed at my not heeding to the information on my forums board and added, "thats what you get for being lazy and not letting me do it! He's a friend so I had to take the chastising and insult).

[ibarria]

Are the GM supplement tablets better than the bars leak's? and how much do they cost?

[STS 310]

I dont know if they are better, its just what I use as many others do. The tablets are a vegetable based conditioner.

I picked some up at the Chevy stealer for about $7.00. I believe that the Bars is slightly lower by a few bucks.

Barsleaks makes the tabs for GM. They are one in the same. Cost is only a few bucks. They are made of crushed ginger root.

picture of my coolant/oil change day products:

(FRAM filter promply was returned after reading bad stories about them)

I used quickfill since I basically blew all the contents of dexcool out of my system and simple refilled, all in all I ended up replaceing nearly all of it.

on the plugs I have a question, does AC Delco outsource and then rebadge the plugs? Or make the plugs themselves? I'm curious because I'm not really a fan of putting in parts made elsewhere when I can get plugs that are made in the US.
