I wouldn't go by Haynes. It's a decent repair manual but you're better off with the one from the dealer. Don't service the cooling system @ 30k as Haynes says. GM has been using Dexcool for quite some time now and that is the only coolant you should run in your system. It's first change isn't scheduled until 100k.

Same with engine oil. Every 3k is ridiculous. My SS requires Mobile 1 but always go by the reset from your last change. Your computer is sophisticated and actually takes your driving conditions into it's calculations. Call your dealer if you doubt me. They will tell you to go by your computer. Brake fluid isn't until 100k not 30k as Haynes states and also requires flushing the clutch system on a manual trans since the break fluid is also fed to the clutch master cylinder. There is no need to spend more money changing fluids when it's not necessary.

I still say changing the fluids will not hurt your car at all. Like they say better to be safe then sorry. Also about the oil life indcator, I say that thing is worthless. Before I figured out how to reset it I had changed my oil 3 times, I was at roughly 9100 miles and it the oil life indacator said i still had 23% oil life.

I do understand that doing this routine maintenance all the time will cost quite a bit, and to that I say if you don't have money to do it at that exact moment in time, wait till you do have the money to do it.

Also I know the brakes and clutch fluid are the same. If you were trying to refer to the manual tranaxle fluid change at 100,000 miles, this is not the same as changing brake fluid. Manual transaxle fluid is different then brake fluid, it is more like gear oil. Also this can only be purchased at a GM Parts Dealer.

I wouldn't go by the comuputer. It doesn't know if you are using regular oil, blended, or full syn. I'm pretty sure the computer cant tell the viscosity, contaminants or particulates in the oil. Go by the odometer. It definitely knows how far you have driven.

Like I said in my initial statement...

I'm not sure where you got confused with tranny fluid but clearly I was referring to the hydraulic systems.

sorry this took so long to reply to but I've been away. So you're telling me as long as my oil life indicator does not change oil soon, I'd be fine. That's complete crap. The I was running coventional oil in my car for the first 9100 miles, and never reset the oil life indicator, and it was still telling me I had 23% oil life left. On conventional oil there is no way ever that you should past 4000 miles, at the most.

I'm sorry but I've always heard to change your oil every 3k or 6 months. Which ever comes first. I'm glad you run your oil longer, and put more stress on your car by not changing your oil more often.

Oil and other associated fluids are cheap, major components are not. Other than the antifreeze, which I personally change about every 50K, the old ruls will not hurt anything and if people fell safer doing it old school, let them, I am one of those people who do not trust the computer, and will keep changing the fluids per old school recomendations, not by electronics that can hiccup.

Every 250 Miles or Weekly Which Ever Comes First
Check the engine oil level
Check the engine coolant level
Check the brake and clutch fluid level
Check the powersteering fluid level
Check the tires and tire pressures

That's ridiculous. If I had to do those every 250 miles I wouldn't want to have a car.

My personal schedule is approximately :

Check the engine oil level - 3 months, before an anticipated long trip, or if I see drips on the pavement
Check the engine coolant level - same
Check the brake and clutch fluid level - 6 months
Check the powersteering fluid level - 6 months
Check the tires and tire pressures - Cobalt checks pressures for me, I check for external damage about once a month

I've owned cars for 65 years and never had a problem caused by following this schedule. But to each his own. Now flame me !

If I followed that schedule I would be checking my fluids litterally every other day.

I am so glad i start a new job next month only 13 miles from my house. I have been commuting 120 + miles each day.

it is not hard to check that stuff weekley, takes what maybe 10 min? and as far as the car telling you the tire pressure that's fine but i still check mine about bi weekly tires are expensive i dont want to have premature wear, also because electronics can and do hiccup. and with the oil, i go by 3k miles not three months but even going over 3k i have never seen drips on the pavement. and i get joy out of making sure my car is running like a top.
