Re: S2 Radiator Fan Upgrade
It does not cool as well as conventional coolant. If your cooling system is not already up to the job, waterless coolant will make the overheating worse.I don't know that I completely agree with that statement. My understanding was that the water in a conventional system can boil locally near the hot spots, like around pistons. That causes the pressure in the system. Steam doesn't really conduct heat. The water pump isn't as efficient when there is air trapped in the coolant. With the Evans, the coolant is less likely to boil, and therefore is able to conduct the heat away from the hot parts better, and the pump is able to pump the fluid more efficiently. It's a really good leak finder.Yeah, at $45 a gallon, leaks are painful.

I use that in several cars, and have had no problems. I like that it doesn¡¯t require periodic replacement, and has excellent thermodynamic properties.Waterless coolant is frequently misunderstood. It's not a miracle product. It does not cool as well as conventional coolant. If your cooling system is not already up to the job, waterless coolant will make the overheating worse. On the other hand, it won't boil until 180C, so you won't have the situation of not having enough cooling and then suddenly almost no cooling as the coolant boils. It might save your engine if your fans fail whilst stuck in traffic, but the engine might eventually get hot enough to cause damage anyway. It's a really good leak finder. It doesn't generate much system pressure, so hoses and seals have an easier life. It requires a completely water free system. You need to use a preparation fluid to remove any water first. -- Paul Compton www.paulcompton.co.uk (YouTube channel) -- This email has been checked for viruses by AVG antivirus software. www.avg.com |
