When I was in my local Euro car parts I noticed some waterless coolant/antifreeze for 'classic' cars ....has anyone used it and what are advantages or disadvantages?? :?
Waterless coolant ??

This was pushed hard when I had my Tr6. Personally I don't think it's worthwhile.

A waste of time and money in my opinion.
There is no better coolant than water, nothing comes close to removing heat as efficiently, so to remove that from the coolant is a step backwards to me. In regular antifreeze/coolant the water does the bulk of the cooling and there are corrosion inhibitors to prevent corrosion, and glycol to prevent freezing.
Water based coolants also boil, this is a good thing. As a boiling coolant system is showing that there is a problem that needs to be addressed, if the coolant does not boil there is no warning sign (other than a temp gauge) to let you know there is an issue and further damage can be caused.
Many race cars these days just run water and a corrosion inhibitor, they are not worried about freezing so no glycol needed. This is the most efficient way of removing heat. Waterless coolants are glycol based and no where near as efficient.

Thanks for all the info ...I will stick to the normal stuff ....good point oilman about the visible boiling ....could save the engine 
My 2004 e85 has done 72k ....should I be thinking about changing the water pump as a precaution or ' don't fix what ain't broken ' approach??

The M54 waterpump is mechanical and far less likely to fail than the electric N52 type. However, the bearings in mine failed and caused it to leak at 78k miles back in Nov'18, not catastrophically but just dripping. Keep an eye on the small hole (circled) for drips but otherwise I wouldn't bother. If you do replace the pump I can recommend the Meyle HD item with a metal impeller and an OEM Wahler thermostat whilst your doing 
And unless they've been done recently you could look to do the drive belts then as well.patriot66 said:If you do replace the pump I can recommend the Meyle HD item with a metal impeller and an OEM Wahler thermostat whilst your doing

Thanks chaps, I did all belts and pulleys/tensioners in the summer as had a noisy pulley
Race car engines tend not to use glycol based coolant as its slippery if spilt on the track. They use plain water and a water wetter additive.
