Wash&Wax water top-up!

Post by L162LZ »

Hi all
My daughter has managed to top up her coolant reservoir with "Wash&Wax" instead of antifreeze (same colour)
I believe she added max about 0.5 litres to the expansion bottle. She then went for a short run to the shops
Any suggestions if this will cause any harm, can we leave it or will it need completely flushing out and replacing with new coolant
TIA for any help/comments

Drain, flush and refill. Water based coolants may cause corrosion and plug the system in vital places.
