Solid mounted fan with fan shroud question?????

[resq302]

Ok, with the 90 degree plus weather and really high humidity we have been having here, I have been considering getting a repro fan shroud and brackets.  My question is.... will my solid mounted fan hurt, help, or no effect, on the cooling system with adding a fan shroud.

This is for my 69 Charger which has a 22" 053 radiator that was recored to a high efficency 2 core rad.  They could not fit in an extra 3rd row into it.  Recently with the hot and humid weather, I have been running at around 210 with getting up to 230 idling in traffic or at a traffic light.  I know a fan shroud will greatly benefit the cooling system at an idle but my concern is the solid fan since usually cars with fan shrouds have the clutch type fan.  Prior to this heat spell, the car would run about 190 with cooling down to 180 driving. I know there is no coolant leaks or anything wrong with the cooling system as I did a coolant pressure test up to 16 psi with the hand pump and it held steady with very very slight movement.  I am just uncomfortable with the higher temps it has had as I do not want to cook the motor.

I know this will not be factory correct for my car as the 22" rads never came with a fan shroud when you got a big block and manual trans.  However, the fan shroud and brackets can be removed when I go to a concours event.  I even considered getting an electric pusher fan to mount in front of the rad but that would mean running a lot of wiring with a manual on/off switch that I would have to hide under the dash somewhere.  The fan shroud would also be a safety aspect too for when I am not going to concours shows.

Anyone have any insight on this?

I had a solid fan on my 73 Ford pickup.  It was a 4 blade fan.  It didn't take me long to hit the junkyard and get a fan off a galaxie.  It had 7 blades with fan clutch.  With the solid setup, it made a huge roar above about 60mph.  The 7 blade fan with fan clutch really quietened the thing down.  And it did a better job of cooling the engine.   Do you have room enough for a shroud and fan clutch setup?  That would be the preferred arrangement.

  The shroud + clutch fan would be my preferance as well.

Brian,

my 69 Coronet R/T with 440 and 053 has the solid fan as well as the shroud. Having the shroud on makes all the difference in my car as to whether it overheats or not.

Concourse is cool but being able to drive and enjoy the car is pretty important too don't you think? Sitting on the side of the hwy because you were too proud to put on a shroud to avoid overheating is a pretty serious trade off.

However, the fan shroud and brackets can be removed when I go to a concours event.

I have to remove the radiator to remove the shroud. I'm thinking you would have to too.

69Coronet,

If I have to pull the radiator to do so, then so be it.  After this year, I doubt that I will be needing to attend any AACA events for awards as I am hoping to get my Senior at Hershey this year.  After I get the Senior, the only thing I can do to go higher is the Grand Nationals which for the most part are too far away to travel to.

I agree about being able to drive the car, which I do now.  This was the whole reason for the debate if I could do the solid fan with a shroud or not.  The nice thing is that I would only have to pull the radiator to remove the brackets and shroud if I need to.  That job would not take that long to correct vs. installing an electric fan and then having to run or remove the wiring if I need to go to a concours event.

As it is, I think I might have figured out the over heating issue (hopefully).  Today on the way to cruise night two blocks from where I keep my car, the thing got up to 220.  On the way home, it was cooler, but so was the outside temps and the humidity was a lot lower as well.  A block away from my house, it was 180 and then was creeping up pretty quickly and got to 220 at my parents house.  This is leading me to believe that my t-stat is partially blocked or not opening like it should.  I am going to order one of the new t-stats that should it fail, will fail in the open position so as to not over heat the engine.

Brian,

Milidon makes a high flow stat.....get one of those and drill hole in the outer ring to bleed off the air in the system.

Would a high flow stat work ok with a stock water pump?

Yep, no problem.
