What do you guys run in your water. I've always had heating problems tell this year. I got the radiator, four blade solid fan, shroud, 1 to 1 pulleys and use distilled water. Know I have to play with restrictors to get it hot enough. I took the motor apart and the water jackets have a layer of rust on them. Its not very much but it has only been a few months. I do run about a quart of antifreeze with it. So what is the best mixture to run with or should I not worry about it. Now that I dont have a heating problem should I go with a 50 50 mix of water and antifreeze or will that bring the temp up to much.

actually if you run 50/50 you will runn cooler

anti freeze is not a racing coolant. Its to keep you water from FREEZING.

I run distilled water, and "water wetter" by redline.

54mm restrictor

1-1 pulleys

stock 3 core radiator

stock 4 blade fan


Im sure we can all argue this until we are blue in the face, but as top notch racers from latemodel drivers to NASCAR and none of them run anti freeze, just a water addative. There IS a reason.

antifreeze actually lowers the boiling point of water.

The best thing to run in a cooling system is distilled water and water wetter as a lubricant.

Goto www.stewartcomponents.com they have a FAQ section that pretty much sums it up on what to run and why.

WETTER WATER by redline is the only thing i use.....ANTI FREEZE hmmmm....dont think i,m gonna Freeze at 7500 rpm and the motor @ 200 to 220....

wetter water will run 20 degs cooler than normal temp. with i think it is 7 oz. of wetter water to rest with water....1 bottle to your radiator....all you need.....

I agree with not running the anitfreeze. We run water wetter in one of our cars and purple ice in the other. Both are running distilled water, 30% reduction pullies, and 1" restrictors. The water wetter mod runs about 210-220 and the purple ice mod runs 190-200, both on gas. Probably going to put both on the purple in the future.

Anti freeze has an addative to raise the boiling point, and other "heat obsorbing" addatives that work just fine in NORMAL conditions. It obsorbs heat faster and dissapates heat slower then water with a racing coolant addative.

so it will raise the boiling point, but you will reach your operating temp faster, and can go past the normal boiling point of water, but do you want to race your car at 20 degrees above boiling? I know I dont.

Water wetter and other racing style addative have a water conditioning agent which "softens" the water to break the surface tension of the water. Then the water can get into the little rough areas of cast iron. without breaking that surface tention, the water or coolant doesnt completely cover the very rough surface of the cast iron. basically making it much more effecient.

There is also addatives that help prevent corrosion, and additional water pump lub.

Anti freeze has alot of these qualities too, but is formulated to obsorbe heat and dissipate it at a slower rate.

Ive even seen it in the rules at a few tracks were it is NOT allowed to race with anti freeze because the chance of boil over or coolant loss getting on the ground. weird huh

all i run is plain old well water no problems ifyour sysatem is right you don't need all the magic potions to keep it cool propper jetting ,timing and good air supply to the rad runs mine at 210- 220 max.the anti freeze deal is a saftydeal also why track don't letyourun it likethey said it hold heat in longer just ask anybodywho has been burnt by anti freeze it's alot worse burn then just hot water

I hesitated to post this question cause I have seen this get debated before. I'm not disputing on using antifreeze for cooling. I dont have a cooling problem and I am using 1 quart of anti and the rest distilled water. Only question was the rust. Do you guys worry about this or is it not a problem. I have used a different additive called Hyper lube. But in this town 1 place stocks this and if they dont have any then I use a little antifreeze to lube with.

Antifreeze raises the boiling temp and has additives for lubrication. It in itself will not make it run any cooler at all. One reason you don't want much of it in your car is if it gets in your oil it really chews up bearings fast. And some tracks don't allow it because once it hits the racing surface it is extremely tough to get rid of it. It stays VERY slick where it spilled and doesn't absorb in or dry up like water will. I don't normally run it but do at times, just a cup full though, the only difference is without it I have to flush the radiator every race and with it I don't need to do that but every few races.

We have tried the potions and plain water. Water pump lube also. Small town and sometimes hard to find, so we tried the cap of fabric softener. Works great and runs just as cool. Now the wife tells me I smell just as good when I work on the car BIGG C

Knowing that antifreeze raises the boiling point of water, not lowers it. I run one quart of antifreeze and the rest tap water, and my car never gets above 180 down here in Louisiana where it is hot and humid all summer. Running the antifreeze will make it if your motor does get hot, it will not boil out as early as tap water. Tap water has a boiling point of 212 degrees, so when your temp gets there it will boil the water out, antifreeze raises it to about 235. I run my timing at 34 with a plastic fan about 1/2" from the radiator.
