What did you do to your truck today?

[NMRam]

Drove it to work and back home.

I called and talked to one of the techs at the dealership I bought it from, and we went through the options available in their system while I was on the phone with him. He figured out how to activate the steering wheel controls and EVIC along with some other options that I have either added already or might want to add in the future! Now I just need to get it in there one of these days and get the programming done!

Drove it home from DFW and am now 200 miles short of 20k which I should have no problem breaking by the one year mark on the 30th.

It'll roll over 104k on my way to work this morning.

Nothing as usual

It kind of sounds like I may have to buy it a new alternator for Christmas.

That sucks .. that you have six gallons of the expensive stuff.

YES... you can still use DEXCOOL.... but you will have to change it on the GREEN schedule.
Every two years.
Once the green has been in it... the OAT ingredients in DEXCOOL no longer do what they were designed to do.

Here is a link that explains DEXCOOL pretty well...

Jim, I bought 8 gallons of Dexcool at one time. They had a Buy-1 Get-1 free deal so I stocked up. Glad I did because they've yet to do it again! So I only paid for half of it.

Thanks for the clarification Jim!

The article says:

In other words, if you mix it, you can't leave it in for 100,000 miles or 6 years, but instead should treat a mix just like conventional coolant and change it every year until the concentration of Dex-Cool is over 90%.

So if I were to flush it out extensively and get out as much as humanly possible, would I still be stuck with the 2yr change interval (assuming that after flushing, the concentration would be less than 10%, so in my 12qt system that would be 1.2qt or 4.8 cups; seems possible)?

Personally I wouldn't risk it...
For a long time there was a GM Powertrain Engineer on one of my Cadillac boards...till GM told him to shut up and get off of internet forums....

Going by what he said about the all aluminum Northstar V8... if Green is "EVER" put in the system... go to a one year or at most, a two year change interval.

According to him, the green stuff plates all the water passages with silicates and it can't be removed.
Again... he was talking SPECIFICALLY about the all aluminum NorthStar V8.

The cast iron V6 and cast iron V8 may be a whole different animal... I don't know.
But considering the cost of a couple of gallons of anti freeze vs the cost of another engine.... is it worth the risk??

For me, it wouldn't be.
"I" would go to a two year coolant change.

You will have to weigh the pros and cons of what "YOU" want to do...

Engineer should have changed his name and stayed on!

I probably won't risk it. I might have an iron block, but the heads are still aluminum. The green Prestone stuff goes on sale for $1.99/gal with a rebate so I'll just wait for that to come around again.

Thanks for all the info Jim!

I'm never changing a vehicle from Dexcool to the regular green!!!!

The green stuff hates aluminum when it gets past it's change interval... Or at least, GM aluminum engine parts...


Last thing I did to my truck was fix the alternator charging problem... Unplugged the power sensor, so the alternator charges like it should, instead of turning on and off.

Dropped the truck off to get the windows tinted and just picked it up a bit ago. Told em I want to match the factory tint on the front two windows and a 15% strip at the top of the windshield. Guess I needed to show them where the AS1 because the ended up going about 1.5" below it. It doesn't look bad, just don't want to get busted.
