My 2007 C6 has 28k miles.

Dealer recommends a brake fluid flush, power steering fluid flush, decarb service, rear differential service and transmission fluid flush.

The differential fluid was changed early on to correct noise coming from the differential.

Are these services necessary based on my low mileage?

No.

not a bad idea to have them done, and quite easy to do yourself
get a turkey baster and have at it
or get the Snap On brake bleeder kit, can be used for multiple things (i LOVE this tool)
age and heat degrades the fluids over time and there is a ton of heat in the engine compartment

decarb lol
aka spray some carb cleaner on a rag and clean the throttle body
or remove your carb?? lol

I would read your owners manual to see what they recommend. Remember service writers work for your money.

If it was mine and planned on keeping it, I would do all but the decarb.

If your trans is auto, I would do a "Change" with filter instead of a "Flush"

If the brake fluid is real dark, then yes. All the rest I'd pass on until at least 50K.

Except that I'd do the brake fluid flush now regardless of appearance. The appearance seems to be a hint about condition but not a guarantee. The fluid slowly absorbs moisture from the air which can eventually cause corrosion or fluid boiling under hard use (brake failure).

Trackheads usually change the fluid before each event, I do our C6 once per year and the grocery getters every three years.

What these guys said

what happened re cooling system? have you had it done once already? if not, I'd say it's due.

Six year old car - I would change out my fluids.

My car told me that it loves having fresh fluids.
I see to it that it has new fluids every 50K miles which is almost once a year.

Hello babyrne,

Please check page 429 of your manual for the Maintenance Schedule. There is a lot of information listed that will help you decide how you want to proceed.

Let us all know what you decide to do!

Hey Don: Where can i get the Snap On Bleeder Kit?...Thanks

MikeERWNC

You can do it with a MityVac for under 40.00.
Or the crappy Harbor Freight vacuum pump for less than 30.00.

^^^^ or do it by the gravity method for free. It just takes longer.

Don 79 TA

i bought it off SnapOn.com
it's BluePoint if i'm not mistaken
it hooks to your air compressor

this works great sucking out MC's, brakes, trans, power steering, etc

i rate it up there with the TomCat Camber bag, and 42" MAC Breaker Bar and the MAC wrenches my friend has at his shop
to me all must have tools

The only one that should be done is the brake fluid flush but only if you haven't had it done in the last two years. Brake fluid absorbs moisture and should be changed every two years on every car. Most car owners don't do it and drive for 10 or 15 years on the same fluid so it isn't absolutely critical for a street only car. Diff fluid is fine for almost forever unless you have been tracking the car. If you have been tracking the car the 09 and up Owner's Manuals say you should change the fluid after each 24 hours of track usage. Since the parts didn't change I suspect that same service interval should be followed for earlier diffs. Transmission fluid is good for at least 100K miles unless you have been doing some heavy duty stuff with the car.

How do you do the gravity method??...And, Thanks to all for the information.

Slip a short piece of tubing over the bleeder valve, so it doesn't drip all over everything, then crack the valve open to drain into a container. It'll slowly drain, but you need to make sure the reservoir doesn't run dry. Let it run until it's clear. Start at RR, then LR, RF, and LF. It takes about an hour, so find something else to do that allows you to keep an eye on the process.

BTW, I found this on the aa1car.com site for what it's worth.
"A General Motors spokesman said Delco Supreme 11 DOT 3 brake fluid contains additives than many other brake fluids do not, so it is essentially a lifetime fluid. Starting in 1993, GM began using a new type of rubber brake hose with an EPM lining and outer jacketing that reduces moisture penetration by 50%. So GM does not consider fluid contamination to be a significant problem."

IMHO, there is no hard and fast rule about when fluids should be changed. The general answer is "It depends." High mileage over a short period of time or low mileage over a long period of time are two examples of when to think of replacing fluids. Your car is 6 or 7 years old now and has only been driven about 4-5k miles per year. One could make the argument that it's time to change them. That said, I'm sure that are folks on CF that never change them out with no apparent ill effects.

The next question is who will do the work if you decide to get it done. One thing is almost certain: you will get hosed by the dealer if they do it. Two examples: I contacted my dealer about replacing shocks and swaybars and installing an aftermarket exhaust. The dealer wanted $1k to do the former and $500 to do the latter. A Corvette specialist in the area would do both jobs for $550!

If you decide to get the fluids changed, by all means do so. But shop around because labor costs will vary widely. The ideal situation would be doing it yourself, as it's the labor costs that kill you.
