so my car runs hotter then i like.. just under 220 on normal days 230-240 on hot days with a/c.. wut did u guys do to get these things runing around 180-190.. high flow pump? water wetter? does that crap work?.. anyone know where to get a fan relay to turn them on earlyer.. say around 190 as mine turn on at 220.. have the air dam brand new factory pump coolant is good stat is a 170 cause thats wut it took to keep it around 220, with the 195 and 180 it was running around 220-240 all the time.. anyone heard of stewart water pumps? used em? any help would be apreciated

 

Bone stock systems shouldn't let it get that hot. Even in deep summer here in Texas, I rarely break 200, and my thermostat is stock, my dual fans are stock. Normal red fluid and antifreeze, although I do run less antifreeze than called for. Straight water cools better, but the antifreeze provides an anti-rust agent as well.

 

Yes water wetter and purple ice are both great products...run one or the other with straight water and no antifreeze.

 

Straight water invites rust or ice. Does the Water Wetter or Purple Ice provide anti-rust/freezing?

The under car radiator air dam is a likely culprit. Owners tend to take those off, because they it. I was guilty of that on my first 3rd gen. Didn't take me very long to put it back on. High temp problems solved.

 

mine did almost the same thing i changed everything then i fugured out the fan was wired the opposite way by the previous owner

 

Answered my own question...

Water Wetter...
"Red Line's WaterWetter® provides excellent rust and corrosion protection for modern cast iron, aluminum, and brass systems.

Use with a long-life antifreeze if freezing temperatures are to be encountered. This product does not contain anti-freeze and its freezing point is 32ºF or 0ºC. Available in 1/2-Gallon containers."


Purple Ice....
"It is formulated to reduce the surface tension of the coolant, which improves heat transfer through the cooling system while providing additional protection against rust, corrosion and erosion.

Purple Ice prevents the formation of scale deposits in the radiator for optimum coolant flow and lubricates the seals of the water pump. It is ideal for use in straight water racing applications or in antifreeze / water mixtures.

Purple Ice is compatible with both traditional ethylene glycol antifreeze (green) and extended-life antifreeze coolants such as GM Dex-Cool® and Ford G-05®.

When used with antifreeze, Purple Ice should be added once a year or every 30,000 miles, whichever comes first, in order to maintain proper performance. When using Purple Ice in a cooling system running straight water, Purple Ice should be added once a year or every 15,000 miles, whichever comes first.

Purple Ice should not be used in new radiators until anti-freeze has been cycled through the system."

It sounds like both are good for anti-rust, but both need anitifreeze added. Not that that would really be a big deal, here in central Texas.
