"Cooling ?"Changing To RT1-25 & straight water,how much should the Temps Decrease?

[lvega@bellsouth]

im currently running factory Radiator with RC fans,50-50 mix,will Rt1-25 & straight h20 drop some temps,im running 180-190*if i make a few hard runs with the car the temps will reach 190-200*seems like the harder i run the car the higher the temps go,but they do eventually drop back down to 180-190,Thanks for input

Using RMI-25 and plain, filtered water will reduce your temps. Have seen 15-20 degrees in some cases. Driving 2-300 miles after flushing and adding RMI will clean lots of crud from the system and help achieve this much improvement.

However, it is the opposite of smart to make "hard runs", especially in the summer, with antifreeze in the system. More than one owner has ruined bearings because of this.

Am doing a head gasket job right now and will need to pull the pan to clean all the "milkshake" and check the bearings because he had antifreeze and made only a couple WOT runs!
