[ROVERNET - UK] Coolant choice

Hi Ali,

I did a bit of searching on coolant choice this weekend, It's the first 
really hot weekend in NY, and the temp gauge on my 2000TC was just at the 
top of the green section and would occaisionnally cross the line into the 
low red. I think re-coring the radiator may be on the cards. The coolant 
quite clean, and I think the engine had been flushed before I bought the car 
last October.

Anyway, apparently the antifreeze does stop corrosion in the engine, but 
also inhibits thermal conductivity (so I was wrong with my last email on 
this). So it doesn't cool as efficiantly as pure water.

I did find a product called 'water wetter' from redline oils that's meant to 
improve the wetting abilies of coolant and thereby improve cooling by up to 
30 deg F. I'll add some to the coolant in my car and tell you if anything 
improves. Has anyone else used this or a similar product? did it work for 

That's about it apart from the fact that I got my NOS carbs' fitted this 
weekend and what a difference it made. I kept thinking the engine had 
stalled when pulling up at the lights, and I'm not creating my own personal 
hole in the ozone layer any more.

Take care,
