Survey: Water Pump Replaced?
#201
Thanks - wow, you mean this stuff... - correct?

Care to explain a bit more how it works, and how it protects? I read the site, but it was a bit minimal...

1) Your coolant system will run at close to 0psi, instead of the up to 30psi of the water based coolants. The cap on your cooling system is 30psi, so that's what you can expect to be the max pressure in the system. Pressure is what is blowing out your water pump seals and the plastic pipes as they weaken from age.
2) Boiling point remains at 350 degF, instead of somewhere around 212 degF if your cooling system loses its pressurization. Losing pressure in a water based coolant system causes a rapid drop in boiling temp of the coolant and flash boiling of the coolant around the cylinder heads thereby warping your heads and/or dropping valve seats. Compared to a leak in a water based coolant system, waterless coolant is not going to blow out all your coolant with the force of a steam engine from the pressure in the system, and second, it will continue to cool your engine without boiling.
3) Since it doesn't have water that causes corrosion, it doesn't need the corrosion package that wears out in normal coolant, so it doesn't need to be replaced, saving regular coolant changes and eliminating your risk of corrosion in the cooling system.
Yes, it does keep the car just as cool, and no the engine does not run hotter. No, it is not bad for the seals in a modern engine, but it is not recommended for old engines that use paper gaskets that need water in paper to keep a seal.

Yes, it's a godsend.

But compared to the work of replacing engines and pulling superchargers charges to replace expensive components, it's a lot less work and a lot less cost. Especially since it's a one-time thing.

Nothing good is easy it seems. You need to get the water content down to 3% or lower. So that means opening up the cooling system in multiple places and blowing out as much of the coolant as possible and then adding their flush product and repeating until you get the water level down. You measure the water percentage with a ~$20 tool you get on Amazon. I managed to get the water percentage very close to zero on both the Range Rover and the Mercedes.

Indeed, many thank you's to you for sharing... And, I wonder if any other listers have done this?
(BTW - would be great to see some pictures of your e type at some point - feel free to PM if you prefer)

Thank you - that is perfect, I will share with my tech and see if we can do it ASAP.
