R33 Gts-t Coolant

[Rudager]

Just had a water pump failure on the R33, replaced it all and get my radiator back from the shop tomorrow with a new 32mm core (supposedly nearly 2x the size of standard, yay) and just wondering how much coolant/distilled water i should stock up on before i get stuck with it half full.

Thanks.

Well... a proper flush with the stocker would probably use the best part of 5L. That's all hoses, waterpump, heater core etc etc

Twice the size cooler, no idea. Buy 2x5L and keep filling until it's at the top. Then run the car until it's warm and you see air bubbles comingout of the radiator cap... add more if needed.

Coolant isn't particularly expensive, so just buy more than you need.
