Subject: Re: 4.5 litre engine problems and upgrades
Just as a follow-up on the controversy about waterless coolants. I stand to be corrected perhaps but I have been informed on apparently very good authority (by someone who designs cooling systems on modern vehicles for a living) that "waterless coolants" are nothing more than neat antifreeze. I understand that nothing is better than water at dispersing heat and antifreeze does not do this anything like as well as water - therefore it is possible that there can be localised overheating in an engine with "waterless coolants". This overheating is not manifested as boiling or rising temperature as with water.
Maybe this is the reason why "waterless coolants" are not recommended for thermo-syphon systems ?
Take great care !
