Stock water pump, fan and radiator, no shroud. Was wondering if an additive like water wetter would be helpful. Or would a fan shroud be a better fix.

I am throwing a bottle of Water wetter in tomorrow , Cant hurt. I am thinking to get a good aftermarket coolant gauge . So I know if correct reading. I do not not enough money to have my radiator redone by Glen Ray. That will be some other year. will putting a trans cooler help?

While I agree a shroud only helps with low speed cooling, once you hit 30mph or so the cooling is all air flow from moving, not from the fan. Showing 200 on the gauge while on the highway is to be expected if you're running a 195 t-stat. Now if he was running a 180 t-stat and doing 200 on the highway, then I would say your cooling system does need some attention. BobN, what temp rating of t-stat are you using? And yes the redline water wetter does help, I've used it.

I broke the new engine in Friday, stayed right at 180 the entire 25 minutes. And it doesn't make a mess like the green stuff. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

Now if he was running a 180 t-stat and doing 200 on the highway, then I would say your cooling system does need some attention. Your thermostat only regulates the minimum temperature, not the maximum. If an engine runs down the highway at 200 degrees with a 195 thermostat, then it will run down the highway at 200 degrees with a 160 thermostat. At best a lower rated thermostat will just delay the amount of time it takes to get to the system operating temperature. The only time a thermostat will affect maximum temps (assuming no failure mode) is if the thermostat is artificially keeping the minimum system temperature above it's normal operating temperature. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

What I did not like was stuck in traffic it would creep up to 200 and I dont have a shroud right now. So I decided to try this electic fan along with my stock fan and it did the trick. I have it on a toggle switch and I only turn it on when stuck in traffic and it brings it right back down to 180. Ron

Once I found a shroud the problem was fixed. Finding the shroud was fun, ended up putting a radiator from a 69 Imperial in and a bud of mine happened to see the shroud hanging on the wall of some boneard he was visiting and called me. Heck of an eye to see that. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
