Is 210 too hot? What's the safe point?

Killer50stang · Sep 11, 2004

With my setup I've been running a constant 210 and I hate it. I'd like to run around 170 or even 190. If I add a pusher fan, how much will that help me. The fan I have now is a Hayden fan, kind of small and I'm not sure how much Cfm's it puts out. My problems is clearance with my setup between my huge radiator and my blower, I have but 3" if that. That's why I figured I could add a pusher. My current fan sits to the side and is not staight to the motor. Any ideas for cooling? ....I've even tried the Water Wetter by Redline...no difference!

210 is a little warm for Aluminum heads. Try Intalling a 180 Thermosat

your fan set up sounds a little strange. have you considered some dual fans that are slim (i.e. Spal)? i might guess that if your fan was more up to speed, your temps would drop (though you did not relate what temps you run in what situations - im just making an inference from what you said).

good luck.

Mine runs 210*F but only when its 110*F outside and I run the AC. That is the best my Mark VIII fan and FMS 8005C radiator can do. You probably need more fan and/or radiator to run cooler. Once you are over the thermostat set point a low temp thermostat won't make any difference, it will still get just as hot.

Good Luck, Don

I have had some success with Redline's water wetter. I am not usually a fan of additives that supposedly help bandaid larger problems, but without cash in the bank to do a proper radiator/fan upgrade, I broke down and tried it out. It seems to work well.

I wasnt under the impression that water wetter was a "band-aid" but rather a racing product. I know that at the shop I used to work for we put it in almost all cars. No Anti-freeze, and we had some anti corossion agents as well. Worked... but water is a better transfer agent anyway... dunno I put it in the 65 and it dropped the temps about 8 degrees farenheit

Camman, remember you live where freezing protection is not much of an issue. you are spot on - water transfers heat ~2.4 times better than E/G coolant.

ive never noticed a tangible difference with the use of Water Wetter myself, but it certainly cant hurt.

i can see each of your points. our cars were designed and tested to withstand idling and high speed operation in freezing and very hot ambients temps. today, many components are not workin as they once did. i see a 160 thermostat (when the car is still running at 220*) as a band aid - WW is not (no more so than running 60% water instead of 50%).

oh yeah, Camman, what types of corrosion and lubrication products did you guys use in the shop? was this for dedicated track cars or street cars (i assume this shop was in Vegas)...... im just curious.

This is a good point, temperatures here never get below zero, and rarely below freezing. This would give cars out here the advantage of not using antifreeze These were mostly purpose built machines. Think folks with lots of money and new sports cars that are not quite fast enough(don't have any idea what that is like). I believe the anti-corrosion product was made by prestone, but it is much cheaper to run Anti-freeze. Out here I run about 70/30 water/anti and have no problems. I do throw in a bottle of water pump lubricant just to be on the safe side

Added to all the above - the pusher fan will likely not help matters as it further blocks off air flow to radiator. A puller fan is more efficient than a pusher. Check out www.spal-usa.com. They have a fully shrouded 24X16 dual 11" set up that move almost 3000 cfm than is not very thick, and the fans are not in the center to interfere with the water pump. Can't you make some mods to move the radiator forward a bit to create some more room? Sounds to me like you need more fan...

Go here to find the answer to your fan controller problems - it's the best thing out there for controlling an electric fan and/or water pump.

being that im going to do an electric fan over the winter, maybe i should ask this now........ do i want the fan to pull or push? benefits or disadvantages?

Miller - ur question was already answered

ive seen mine run close to 210 when im running it hard. mine runs a constant 190-195 w/a 180t-stat & water wetter (didnt seem to make a difference)

thanks for the info; i run about the same ratio. you hit one reason i asked on the head - it is often cheaper to just run a small ratio of antifreeze rather than to buy special addititives. i was just curious.
i too, have no idea what it is like to have a new car. nor do i know what it is like when that new car is not nice enough and i feel this burning impulse drop it off to a shop to have it made faster.

thanks again for the info.

Michael Yount · Sep 12, 2004

If you have sufficient fan and radiator capacity, your coolant temp should be just about equal to your t'stat temp, or your fan activation range - whichever is higher. Said another way, if your system runs at 195F w/180F t'stat - your system isn't capable of rejecting anymore heat. As ambient temps climb - so will your operating temp. You're running right 'on the edge'. I'd get more fan and/or radiator capacity.

anytime bro... the shop was right next to shelby american, so I got to get my feet wet in there every once in a while, when we had time to step away from the series one.

camman - may be out for SEMA in Nov; buddy wants to tour the Shelby facility -- is that a worthwhile way to spend a few hours?

Is 210 too hot? What's the safe point?
