Coolant flush

[Davidjstix1]

My dealership tells me it's time for a coolant flush. Apparently, it's recommended every 5 years; I've had my 2019 for nearly 6 now. Anyone else done this? it's $500.

You can do it yourself. Do some research. Ridiculous mark-up.

I had it done at the time they replaced all the brakes and the transmission modulator. I didn't know what it cost but in 100,000 miles they've had virtually none of my repair bills because it didn't need any repair. For the little bit of work that they get on an EV
figure I threw them a bone

I don't recall having done this on any of my ice mobiles because it's been so long since I had and Ice mobile. The only time I even messed with the cooling systems was when I had to replace the thermostat.

If you cannot find it on Google go to your nearest library and look for an Edmonds car repair manual.

Looks to be pretty daunting job? Does one really need a vacuum device?

has any tried one of those drive-thru oil/coolant change joint ?

I wouldn't trust them with an EV. I just replaced my hubs and axles myself at 40k. I bought the synthetic fluid for a gearbox fluid change. Doesn't look hard once you get the belly pan off. Two drain plugs, a fill plug and a "Check fluid level" plug. There is a video on Weber Auto on the Bolt "transmission:" that points out the plugs and instructions for drain and filliing. As far as coolant goes, it's after the tranny fluid. It can't be that hard.

yes, it's usually not "hard"; for me it's the hurdle to get started. The coolant system also needs to be burped off air bubble as well.

Does it take a vacuum tool to complete the refill properly?

yes if all the coolant is drained and replaced, there are 3-coolant loops. The reason for coolant replacement is due to the degradation of coolant's viscosity and lubrication property. My plan is to "dilute" the old coolant with new coolant, by siphoning out the old coolant from the 3x reservoirs and fill up with new coolant, roughly 3-4 times within a few days.

Yesss.......that is just what I did with my rack and pinion steering fluid in my Honda CRV.
