i was thinking about changing my coolant to waterless ,

has anybody done this and is it worth doing 

thanks

to me its a solution to a problem that doesn't exist

What's wrong with normal antifreeze? Pressure build up is a good thing as if you have a leak you find it alot faster than with waterless... Plus waterless coolant can't just be poured in once the antifreeze is drained, you need a treatment fluid first, which is then drained and then waterless can be used..

Very expensive though

Antifreeze and water for me!

it is only really useful for cars that are show queens or are just on display where having coolant just sitting there doing nothing can be an issue but the correct mix of antifreeze/coolant does a similar job. and it is easy to top up if needed.

I've use it because I got given it so though why not it's ok but like said you have to use the first solution for a while which you can use again, then the next
it's great however its just the same as antifreeze etc I would say it's a right bummer if it leaks all over the floor though at the expense
If I was that worried about overheating I would change the water pump ,and the pully for the smaller if you already haven't then the thermostat for a lower degree one
Or one step further which I've done is dry decking with the water pump modification to the block which I've had absolutely no problems with but to be honest it's real overkill

I've bought it because I like everything to be overkill so I don't even have to worry about it. Still running the prep fluid just now because I haven't actually used the car yet and the new water pumps leaking so that's gotta be changed first! But if you're a worrier, it's a good buy :)

Here is the bit I don't get, the waterless coolant does not pressurise but from my knowledge of plumbing that is actually a bad thing? Pressured systems run smoother and quietly, they stop airlocks and keeping the system at pressure (with anti corrosion inhibitors) will not allow rust to form as there is no oxygen? I know the waterless has no water so in theory the block should not rust even when exposed to oxygen (hence the flush before use?) but even still like most problems we get offered solutions to (there is a pun there) that we did not need they can be overcome just by keeping the system clean and giving it a good flush and refil with glycol every two years, not doing that is what causes the trouble like my poor old rusty Mayfair system due to neglect rather than the antifreeze/water, my Morris 1000 is as clean as a whistle after 6 years of my care!

At work we ran waterless coolant in all our regular cars, road and racing. Now we just use deionised water and glycol antifreeze 50/50. The waterless coolant actually caused more problems than it solved and was much more expensive. We had an increase in overheating issues and on some race tracks marshals were getting funny with the use of it as it lowers the coefficient of friction of the track and tyres a huge amount and any spillages increased the risk of spins and accidents.

Also on a basic level waterless coolant also cannot transfer heat as well as plain water or a 50/50 mix of coolant and water. If you already have over heating issues then a 100% glycol mix, which waterless coolant essentially is, will cause more issues. The fact it doesn't pressurise is offset with the fact it doesn't boil at the same point as water, the pressurisation in a normal system is to raise the boiling point. 

It is however very good as a corrosion inhibitor compared with water or water/coolant so for cars that are stationary for long periods or rarely used it could offer a good alternative provided you have no leaks as it will cost a lot otherwise!

Even though OP has not mentioned over heating. If you want to help the system to work better as some water wetter.

I found t more useful in my 205 daily driver. The system still gets decent enough pressure not as much as with water/coolant. Its predictable in traffic I would say especially in summer. The old 50/50 mix I used would creep up a bit higher before coming down. Countless hours of life lost sat in motorway traffic this year. The one draw back is the expense that it costs to replace if you get a leak and the fact you can't just go anywhere and buy it. Upside is you don't have to worry about getting the mix wrong if needing to top up the system, no water to boil away and reduces local hot spots, it will still give decent heater temp.

You will still find leaks easy enough because you will recognise the smell straight away, and it stays the colour it went in when it comes out the one I've got is a red colour and you notice that on the floor and your hands so it's easy to spot.

Been using it for nearly two years now with no issues. But if you are using it to cover up over heating issues then it won't help that much as that will be an issue with cooling system it's self as already mentioned. I noticed minute differences and this is with a system that had no leaks and new parts, new coolant only reason I changed to it was because I blew the head gasket and had to empty the entire system and it seemed like a good idea

[mk1coopers]

I was looking at it, after we had this discussion I've also gone for 50/50 anti freeze and de-ionised water
