After 13 years as an auto parts store outside salesman,the only thing
I could figure out battery life wasn't who made the battery but who owned the battery!
Go figure.
Good Luck!
If the coolant looks good,don't worry about a flush.
Just drain what you can and refill a 50/50 mix-distilled water preferably.
Don't overthink it!
Good Luck!
I would think good old conventional green coolant would be fine.
My L2501 has it as well as yours.
Don't over think it!
Others will disagree!
Good Luck!
Have been 100 hour change after the 50 hour service on the B3030-recomended interval.
Using WIX oil sample kits.
2-3 years between changes.
Always come back like 9!
And I'm the guy that does my cars at 3K with dino!
If your B2782B is worn out,you will will not be happy with a lesser quality blower that you are asking about!
Witch most likely won't work for you without much money spent.
Good Luck!
