Over pressurising system & water in oil

Vauxhall Astra & Rover 75
Used this on 2 occasions and found it to be brilliant. Changed oil afterwards and solved the problem. On my other car, the system was over pressurising and reading false temperatures bringing fan on. This did the trick. It's well worth the price and saves on expensive garage bills and ultimately a new head! Don't be fooled by cheaper products claiming they do the same!
