Instructions say 30 mins tickover but mine needed a good drive to get the holts goo from the overflow to circulate around the system cos of airlocks. I was quite sceptical about it working as coolant was literally flowing out but much to my amazement it worked. Must buy another one and put it innthe glove box. Also, this is the best version as it works in the presence of anti freeze and will also seal head gaskets if thry are leaking. Great for an older car!!

Had a leak which was losing 4 litres a day. Poured it in and ran engine for 30 minutes. Topped it up and level has been maintained for a week! I bought the premium product which was more expensive than most, but since it's done the job worth every penny.
