Hi all,
Let me clarify my point that ethlene glycol is not as efficient a coolant as
water...
Here's a reference;
"The specific heat capacity of ethylene glycol based water solutions are less
than the specific heat capacity of clean water. For a heat transfer system
with ethylene glycol the circulated volume must be increased compared to a
system with clean water."
http://www.engineeringtoolbox.com/ethylene-glycol-d_146.html
There is even a chart, which indicates running 50% ethlene glycol as a
"coolant" requires an increase in your coolant capacity of 14%, assuming your
engine is running at around 185 F
My owners handbook refers to using water as a coolant, and only adding ethlene
glycol as an antifreeze in freezing conditions. But what would the blokes that
built the cooling system know??
I think most people who have owned Healeys for a while, in a hot climate, not
subject to freezing conditions, have realised they have less overheating
related issues with water and some kind of anti corrosion protection, than
they do with 50% or so ethylene glycol.
I solved all my bugeye sprite cooling issues when I changed back to water 30
years ago. I'd put 60% ethylene glycol in it to drive down to the snowy
mountains. It overheated all the way there, and all the way back.... No
problems when I switched back to water. And yes, it was a heavily modified
sprite, 1220cc, 1.5 in SU's etc
Best
