It’s been recommended that I change the coolant on the Zoe for £349. Is this really necessary? I can’t get over the cost. The car is 5 years old (2016).

can any competent garage just stick one of those things into the coolant radiator expansion tank, that looks like a turkey baster and has a red ball in it that measures the amount of etylene glycol antifreeze concentration in the expansion tank and add accordingly? - I reckon with the £349 charge they have to disconnect the 370v DC system , then wait for it to de-energise (think it takes 20 minutes or so) , and have to wear the high voltage stuff to drain out the coolant to replace it and this is where the cost is .... and possibly the long time it has to be booked in for (= more hours more labour charge)

dont forget it is also 'recommended' to replace the 12v battery after 4 years even if it is working perfectly fine - and then the Brake fluid change after so many years ... this all makes servicing very expensive on the Zoe

Coolant is the only one I paid for. Its also used to cool the motor during charging too. As liquids go in the Zoe its probably the one worked the most. Brakes worth getting absorption check rather than replace. Battery just monitor it and keep it topped up in cold times when not using it. But coolant could be the difference between charging and something that goes pop when it gets too hot and an expensive bill.

And yes Renault charge a stupid massive premium to disconnect the HV. Use any other Hevra or EV specialist garage.

Thanks for your reply. I will phone a Hevra garage!

It’s like £100-150 at a HEVRA

I dont think its needed with the long life coolant in the car, its not exposed to air and as long as it still has its colour its fine. They can test it also.

We had this talk a few months ago,
5th Year service
DSG were giving better prices if you really want to get it done but asking them to test the coolant first seems to be the simplest way to call them on their BS.

To change the coolant, poor design means that they need to disconnect the drive battery. They need technicians who have been qualified in handling the high voltages involved. They need the proper PPE to deal with the high voltages involved. I'm sure you can find someone who can cut corners on the training and/or the PPE who will do it for you more cheaply.

I have removed the traction lock / fuse thing (under the drivers carpet) and drained down the zoe on a couple of times (this is me personally, I am not telling people to do this themselves or promoting people to do it because we are talking high voltages) - so yes I dare say there will be some garages that will skip the wearing of PPE high voltage gear and cut corners.

flippin' eck that is cheap. I know it shouldn't take long but I damn. I assume they aren't getting the old coolant out just by cutting a hose in half and tapping it back together?
If I ran a garage I'd want to charge more than that just to get the car in to the workshop, before doing any work on it.
