added cooling
hello guys,
you have been very helpfull in the past with issues i have had with my
1990 mercury cougar 3.8 efi v6.
i would like to know if there is any low cost way to add cooling to my engine. i have never overheated, but in summer time, i do run above normal and i notice a decrease in power slightly. i have no thermostat in engine, when i took it out, it helped a little. can i use something diferent other than antifreeze?
I may have to move to florida and i dont want to have my engine running so hot, car is in mint condition

If you have a transmission radiator inside your engine radiator, disconnect it and install a separate transmission radiator. Look into a fluidyne aluminum performance radiator. it will flow more antifreeze with a minimal loss of pressure. Also, using a higher concentration of water to antifreeze will enhance the cooling ability, but at the cost of a higher freezing and lower boiling point.

2 things come to my mind, 1 you need the thermostat in the engine to keep from over heating. It will run cool for a short time but will over heat on a long run, the coolant has to be restricted to cool it through the radiator. 2. ANTIFREEZE is ment to be reduced to cool properly.60/40 is good, but 50/50 is recommended. It not only raises the boiling point it protects from freezing. Does this help? good luck.

Amen. Antifreeze does not actually cool anything. It is there to 1. raise the boiling point of the mixture 2. lower the freezing point (you wouldn't want your engine to be a big ice block) 3. keep the corrosive properties of water in check. And yes, greeneye, I would get a separate trany cooler. It will save your butt if either of your radiators leak, and it will keep both radiators much cooler.

oh, and put in a thermostat. it does allow less water flow, but it will allow your engine to heat up much quicker, keeping it in optimal temperature range. Luckild, going without a thermostat will help an overheating engine; many racers take theirs out. The radiator will restrict flow plenty. Sure the water coming in is not as cool, but the water conimg out of the block has not been in there near as long, and will be much cooler. Works both ways

what do you guys think about npg instead of anti freeze?
check out this link, its about 25 bucks a gallon, but in reading it seems to be a good alternative.

I'd not even bother investigating it. Regular old ethelene glycol in a 50/50 mix with water has accounted for who knows...Billions of miles?
If it ain't broke, don't fix it. I'd think your engine should perform fine with the factory cooling system and a 50/50 mix. If it doesn't, then I'd find out what is wrong and fix that.
If you have a latent problem I'd doubt any fancy high dollar coolant would be a "magic bullet".
I believe NASCAR runs dry nitrogen gas in their tires. But, you sure don't need that on the street. The point being, there are all kinds of products, chemicals, etc. to spend your money on. IMHO, most are not needed and if they ever are, there is an underlying problem that the "fix" is needed for. Sort of like treating the symptom rather than the disease.
Let us know what you decide and how it turns out.
Thanks.

And all these answers get the golden seal of approval from Tom Longo. Everyone is exaclty right. Put the thermostat in and take your truck to Jiffy Lube and have them flush out the radiator and refill it with the proper mixture.
Here is a great link about water tempurature and pre-ignition. Some good reading. I use Water Wetter in my motorcycle and am happy with the results as I also live in Hot Florida.
Check it out.
