Coolant bleed screws
Coolant bleed screws Hey folks, this might sound silly but I don't see the bleeder screws for the coolant. On my LT1 they're easy enough to find-right on the t-stat housing but I don't see anything on my 'LS. How many screws are there and where are they located? Thanks in advance...

...no bleed valves on LSX engines.. I leave the cap off and run the motor for 15 minutes to get air out.
I would be careful about green.... most does not mix well with yellow GM antifreeze..... make sure you read the label first.

As for my LS1, yeah I'm banking on Prestone's claim that their green'll mix with anything. I'm making sure to flush the motor out as best as I can. I wish I could just run a hose while the motor's running but I can't get any of this stuff on the ground.
Thanks guys...
i just bled my coolent yesterday with the heater on and car on the ground, car started going past middle on the temp guage, turned out there was a big *** air bubble inside waiting to come out.

Phew. All done. Leave it up to me to pick the hottest day of the year to do this. Now I play the waiting game, to see if any issues come up. Strange thing though, I couldn't get any of the cars to take more than two gallons of mix-I guess I didn't get enough of the flush water out...

Verdad Gallardo Alright, well 2 weeks or so later the cars seem to be running in the proper temperature zones. I couldn't help but notice the antifreeze testers at the parts store, so I picked one up. Now in case anyone doesn't know, some of these testers, like the one I bought, supposedly indicate the strength of the coolant based on how many little ***** end up floating in a sample of coolant. I tested the cars and the results weren't pretty: I averaged one floating ball which, according to the user chart, says I'm only protected from +20 to 215 degrees.
What exactly is this thing saying-that there isn't enough coolant in the mix? Not enough water? Dirty coolant mix? I don't get it...

Generally speaking the more coolant in the mix will improve the temp range. IMO if your following the directions and doing a 50/50 mix, you should be fine. In Connecticut, we get down to -30's some days and I have not had an issue. @ your location do you even get the freezing point?

I'm thinking this is what happened: I thought I'd be smart and buy 50/50 pre-mix so all I'd have to do was just pour the stuff in. It didn't occur to me that I wouldn't be able to get all of the flush water out of the blocks. I'm guessing that the 50/50 mix is really diluted now. I guess I'll just drain a bit and then pour straight coolant in.
All of this is dependent on my understanding of the coolant tester: I THINK it's telling me there isn't enough coolant in the sytem. If you guys think otherwise lemme know...
