Default Fluid Changes...

Hey guys,

Im real big on maintenance for my vehicles and motorcycles.

Im going to drain and fill the brake fluid, transmission and clutch fluid and perform a radiator flush.

I do these services every 1.5 years. I have a 2013 GS Coupe M6 w/17k miles (i got it w/15k in July of 2018). I put on about 2500 miles a year. I live in so cal. No track days, drag strips or aggressive driving (for the most part).

Do you think this is excessive?

Thanks!

I know Germans change their brake fluid every two years. Coolant and tranny probably good for 4-5 years. Axle about same also.

It approaches OCD but if it makes you feel better, don't worry about it.

Brake fluid and radiator every 5 years is sufficient, especially with the low miles you are driving. Clutch fluid, based on what I have read about issues on the forum, should be done annually. Auto trans and differential I won't do before 10 years.

Thanks guys. I do it for peace of mind really, however, I can see how it could be a little overboard.

Not that I agree with how my wife handles the maintenance on her cars, but her Caddy is 11 years old with 114K miles and has never had any fluids changed beyond the engine oil. It still has the original brake fluid, trans fluid, PS fluid, axle lube, and coolant.

What does the manual say? When in doubt, follow that...

I have been wondering about changing the A6 fluid and filter in my 2012. It only has 39k on it now, but with it being 7 years old I figure it would be a good thing to do. Found a good video about changing it including jacking up the diff/tran to get to the last few bolts that hold the pan on.

Should I put this into the list of things I should look to do soon?

Definitely more involved than a oil change, but looks manageable. Any idea what a dealership would charge for it? Trying to figure if it is worth doing myself.

My dealer quoted $600 to perform a coolant flush, brake fluid, clutch and trans fluid flush.

Worth it to me to have all fresh fluids

Yeah definitely worth it then! You have the M6, right? I believe the A6 is even more involved to change filter and fluid.

I changed all the fluids last year but my car was 5 years old & ~40,000 miles. Clutch fluid gets sucked out of the reservoir and replaced about 4 times a year. Thanks for reminding me, I should do that again.

For the life of me, I don't understand why people say you have to jack the differential. I have changed my fluid using an open-end wrench for the last couple
bolts. Remove the "difficult" bolts first and install them last. Be sure the car is level and remove and remove the "drain plug" ( not really a drain plug ) to avoid a
major fluid mess. This plug is a little stand pipe to attain the correct fluid level at conclusion of the job. Follow all maintenance steps...it's really not a tough job.
Personally, I over service the fluid level so when the plug is removed, after the correct temperature is reached, fluid flows so ya don't have to get under there
and add some more. I feel a lot better wiping out the pan and installing a new filter myself than some dealership. That's just me.

Back when I had a CTS-V, I would take a syringe and suck out the clutch reservoir of old fluid and add new fluid to the correct level. After cycling the clutch for a few thousand miles or 6 months or so, I would repeat the process. My clutch fluid always looked new. C6 with an automatic now- I sure miss three pedals!!

Obviously yes.
But I do the clutch fluid often, because it's easy and good preventive maintenance.
