Subject: Re: 4.5 litre engine problems and upgrades
Just in case you missed it on the VSCC Forum there was an answer about my thermo syphon system point above posted (by someone who seemed to know) as follows : -
"I suggest that the reason is because Glycol does not expand as much as water, does not absorb as much heat per pint, and is thicker (more viscous). All these factors make it less successful in a system which relies on expansion, etc to work, with no pump."
Of course if the coolant does not absorb as much heat (as water) then maybe this is the reason why you can get localised overheating in a system which is very inefficient in design (as I think we all know).
Anyone with more technical knowledge out there care to comment please ?
