Well for one reson the pressure in the cooling system is +0- PSI
No more leaks, replaceing water pumps, gaskets, hoses and from what I've found
out so far the motor runs much cooler.
Not to many people have even heard about it altho it's been around for
Mostly large fleets of trucks use it. Cost about $200 for a Ford E350. But if
what I've been told it's worth it.
Gee $200 in the middle of a vacation and a day's down time it's worth the
up front expence.
I want to find out all I can from someone that knows.
