I have a 2019 Stingray with M7 and looking to see what maintenance I should do at 30,000 miles. I know change the oil, but when I looked in the manual it mentions changing the coolant at 150,000 miles but it also states to change coolant every 5 years. I would imagine there are very few drivers who drive over 30,000 miles a year in their Vette. I have already replaced the cabin air filter a few times so that doesn't need replacing, but I was wondering if I should go ahead and replace the engine air filter (recommended at 37,500)?

What other maintenance items do you all recommend that aren't stated in the Service Section of the owner's manual?

Thanks.

The brake fluid should be changed. This should actually be done every two years. The clutch fluid should also be changed…as best as it can be by the Ranger method (sucking out, re-filling the master cylinde4 and pumping the pedal multiple times, repeat until fluid is more or less clear).If it is dirty, change the engine air filter. My practise is to change the engine coolant every five years or so.

This is for a 16 Corvette but it should be similar to your model year.

I have a 2017 M7, 32,600 miles. I replaced the air filter and cabin air filter this past December. Neither was real dirty. I've changed the oil and filter twice a year since taking ownership new. I just this week had the coolant flushed and refilled. I know its over 7 years but with the milage, coolant was in pretty good shape but it was time. I'll probably do the clutch and brake fluid next oil change...

Definitely do the coolant change and I would do the brake fluid. Carefully check all belts and hoses, check brake pads.

You didn't mention if you are the original owner and what has already been done. If original owner and nothing done I would suggest the following based on time not mileage.

brake fluid
differential fluid
transmission fluid
coolant
clutch fluid full flush then maintain with Ranger Method

You change the oil twice a year but only have 37k on it? I change the oil when the oil minder says to, and it consistently says to change it once a year. I have about 78K on my 14 so 8K miles a year avg. Its a z51 so it has almost 10 qts. Is yours a z51 also? If its not and has less oil that might explain it?

I just hit 25k on my 2019 and did the 5 year stuff plus...

Brake fluid (2nd time 5 years)
Coolant flush (first one, was clean but still did a flush since it was easy)
Oil change (I've done many of those lol)
Clutch (Ranger after every oil change)
Diff oil change (once at 2k, once at 22k)
Air filter (12k and now)

I tend to write most items down on my oil pan so the next owner has a trail and because I am nuts. Coolant breaks down over time and you do need to change it at the 5 year mark regardless of miles. I'd change that for sure, plus brake and clutch fluids.

Also my filter was abysmal with under 15,000 miles on it. I'd change it!

Old vs new!

My 19 has 11800 now. I bought with 8500. I changed the air filter(blue one), cabin filter, & had the rear end fluid & oil changed &10K. That has been it.
I doubt PO did anything but 2 oil changes.
I may do the ranger method on the clutch fluid & the coolant soon.

WOW!!
That old filter is really filthy for only 15k miles of service.
Good catch on this one.

Second owner, it was two-years old with 8100 miles on it when I bought it. Have already had the differential changed, have done the Ranger method a few times myself.

I get the oil changed when the oil minder percentage gets low; I never mentioned anything about my frequency of oil changes.

How many miles are you driving a year to change the oil and filter 2x a year? Or are you changing for seasons?

guido7834

I'm sorry, 32,600 miles. I meant I've changed the oil once a year, every spring. I don't know why I said twice, must have been thinking of my truck. Living in the northeast, it didn't get driven much at all through the winter. I'd change it early spring. I averaged about 4300 miles a year

your brake fluid will look like used motor oil coming out of the calipers if that has never been done
clutch wont' be much better.
you could probably stretch the coolant to 7 years. I did mine around 7, came out looking brand new.
