I used a smaller pulley from a Poly 318 to speed up the pump & pan on a later RB; same bolt pattern, depth is the trick.
Blade pitch matters on aircraft prop engines & watercraft, not sure what options exist for cooling fans.
Radiator fins aren't plugged with paint/dirt/whatever, are they ?

Since you went from 50/50 coolant mix to nearly straight water with chemical wetter,
that has an effect like having a 30% gpm pump boost,
due to the greater thermal capacity of straight water.
To me that indicates the system is “airflow limited” not liquid & pump side limited.
I would now boost airflow somehow to further test.
Start by blowing more air on the parked stationary vehicle with a large electric floor fan or leaf blower.
If this added boost of airflow lowers the liquid temperature down to the 180 degree setting of the thermostat,
then try a larger diameter fan, or a same diameter fan with more blades and/or pitch.
My thoughts as well. The thing is it runs about same place on the gauge driving down the road at 55 mph I cant get the idea out of my head that the fan blade is to small for the shroud opening. and/or not enough blade pitch The cars Ive had in the past you could really feel suction in front of the radiator at idle . This one IMO doesnt pull like I think it should/could. And it doesnt really help much when i bring it up off idle Also, base timing was almost 18-19 degrees , I bumped that down to about 15 to see if it had any effect , So far nuttin

I pulled the water pump off of it tonight so I have a baseline / know exactly what I have.
And its an 8 blade pump and the fins go all the way to the outer edge of the casting , just barely fits in the hsg itself . So I think its as good as Im gonna get in regards to a pump

A few years ago I battled a cooling issue with my Charger and I went through the same process as you. Long story short scale/rust/crud in the block broke loose and lodged in the radiator cooling tubes, which limited flow through the radiator. I had the radiator rodded and I put in a tefba filter which solved the problem. I was surprised how much crud it captured. I talked to Gus (fourgearsavoy) a week back and he recently had a similar experience - he put in a filter and trapped a bunch of crud. If all else fails, have the radiator rodded and put in a filter (at least temporarily).

I cant get the idea out of my head that the fan blade is to small for the shroud opening. and/or not enough blade pitch The cars Ive had in the past you could really feel suction in front of the radiator at idle . This one IMO doesnt pull like I think it should/could.
Bill, I don't know what blade style of fixed fan your running, but is it possible the fan's mounting is flipped or "backwards"?,....just a thought, you never know?....I've seen it before Mike

And its a direct drive fixed design 7 blade I currently have a couple friends cking for a smaller diam wp pulley. And if can find one i would like to update to a fixed blade if i can To speed up fan speed and coolant flow.

My new toy went out last night for the 1st cruise under my ownership.
1966 Satellite hemi auto 3.54 dana
And I feel the car runs a little warmer than I would prefer. right at half way up the stock gauge on the interstate. But once in stop and go traffic it warmed up a little more then I would prefer,. it,,went nearly to the top of the gauge. and spit out some coolant once parked .
The ride back home on the interstate it remained in the center of the gauge the entire drive. That I think I can live with .
I have to find out what thermostat is in it .
Car is a street hemi, auto, approx. a 18" fixed blade fan , stock radiator and shroud. the OE rad had a new 3 row core done when the car was done. But has only had maybe 1000 miles on it in 15 plus years.
I don't know yet if the block is bored or not. SO I need to do some digging. before getting to radical.
BUT, ,,,,,
My questions is, has anyone used the stuff called water wetter , results good or bad .
If I can cool it off maybe 20 degrees I would feel much better . The weather last nite was nice upper 80s for the drive up and maybe lower 80s for the drive home If it cools fine on the freeway but not at low speed then it is probably an airflow issue. Might need a fan with more blades or perhaps the position of the fan inside the shroud needs to be fixed. Also a good idea to verify that the radiator is in good shape. If the car has been sitting a lot then the radiator core could have some plugged up passages. Cars that sit a lot develop lots of little problems like that. rite there --- ^^^^^^^

I'll throw this in here; When I built my first stroker, it would heat up around town, did good on the road, but got warm at slow speeds and them would boil over from heat soak when I parked it. Annoying and embarrassing. After a lot of experimenting, I pulled a fan from (I think) an 80s Dodge pick-up. It is huge. The blades are big and have a lot of pitch to them. The problem was, of course, that it wouldn't fit in the Cuda's shroud. It would fit the clutch just fine, but was too big to go into the shroud.
Fortunately, the blades are aluminum. I just marked them, cut them down to size and installed it. That did it. It moves an enormous amount of air. I had it on that engine for several years and have now had it on this Hemi for 4 or 5 years. But it will wear out a clutch every few years, depending on the amount of driving time it gets.
The fan may not be perfectly round or in balance. But it has not given me any problems and I spin the Hemi to 7,000.
Just one experience.
Master, again and still
