What colour liquid is this please ? Will it change the coolant colour. thx

The colour of it is a rusty red and yes it will change the colour of your coolant and really should only be used if you have a leak

Would this stop coolant leak on my lexus rx400h?

If it's a minor leak on a radiator this is worth a try. Worked for me.

Will it be safe to mix it with comma xsg1l 1l xstream g48 coolant and antifreeze?

As far as I know it's OK with any coolant. I checked the website and it states it's ok. I have used it in Audi Vw and Renault with no problems.

I have a Citroen c4 with coolant leak into passenger footwell. How do I use this please?

If the leak is coming from the coolant system, tank ,reservoir or pipes pour this liquid into the filling / top up tank making sure it`s not overfull afterwards, sometimes it takes two bottles ,doing what it says on the tin and hopefully it should do the trick.
