Default Change fluids?

I have a 2015 Stingray which I purchased in 2018 at 7407 miles…it now has 19980. I’ve had the oil changed every year and put in new battery every 3 years whether it needed it or not. Had triple flush done, tension rod pulley replaced and front control arm and stabilizer bar replaced (bad bushing). It goes in to secure temp controlled storage Nov 1 and comes out May 1. I try to put about 1100 on it now a year……do I need to do any fluid changes like brake fluid or coolant…..by the way it drives perfect.

Brake fluid, coolant and rear end fluid all should be done by now if they haven't already been done.

Brake fluid is way past due.
Coolant is way past due.

Given the age and lack of mileage, differential fluid wouldn't hurt.

Ditto. People have found on some C7's that the diff fluid wasn't correct from the factory. Easy to do yourself.

Default Diff Fluid

I did my diff fluid yesterday. It was low and sparkling. 2.25 qts came out and almost 3 qtrs went in.

I intend to do all my fluids this summer on my 14. Most of which was done in 19, so its 5 years is up.

-Coolant
-Brake Fluid
-Clutch (another ranger change, quarterly)
-Transmission Fluid (M7)
-Differential Fluid

Besides usual oil changes and air filters, not much more to do. Maybe ac if you’re worried about that.

These three things definitely should be done.

Brake fluid absorbs moisture over time. Some recommend a complete flush by sucking out the fluid, replacing it with fresh fluid and then flush all the lines. I do it every 2 years because that was what MB called for and since I was already having the power flusher out, might as well do it for all the cars. I believe coolant additives might be suspect after 5 years per GM and 3 per MB?

What do you mean by sparkling? Like new? or full of metallic pieces?

My guess is metal particles. Probably due to be serviced.

They tend to care about time more than miles.

Very nice ride! Maybe also change your air filter and cabin filter if these have not been addressed yet.

But changing the battery every 3 years seems to be way overkill unless you live in a super hot climate, and even then you're probably safe to go longer. I'm still on the original battery in my 2018 and will probably go a couple more before changing it out. I'm also on the original battery in my daily driver (2016 Civic) I have got as high as 9 years out of a battery in one of my cars. The climate here isn't super hot in the summer, nor is it super cold in the winter, so battery life here tends to be really good.

Battery life is difficult to predict.
We always attach the battery tender if the car doesn't drive for more than 4 days.
On our 2001/2006/2009, the battery was in the hot engine compartment and so I preemptively changed every 3 years.
When we got our 2017 where the battery stays cooler in the trunk, I tried for 4 years, the battery died at 3 years + 10 months.

It may or may not be. We can't tell how often he's killing them.

Yeah that was pretty much my point. Replacing a battery every 3 years is nuts in my opinion especially since in the OP's case it sits on a tender for 99.9% of its life.
