So, I finished my restoration gosh, almost 15 years ago. Not sure where the time went. 55 Bel Air 2dr HT, 265 V8 2bbl, With PS, and powerglide. All stock. I played with it a few years, not sure but put at least 1500 miles on it. Other things in life took over, but over the next couple years want to get back to it. Still looks great sitting in storage.

One problem I had back then is that I did a parade once, and I was overheating. I didn't have any issue driving around normal.

Is there a reproduction AC fan shroud available these days? I know they didn't have one originally unless it had AC. If there is, will it bolt to my V8 core support? I'm hoping for a nice metal one. Back when this happened I bought a plastic two piece one offered at the time, but never installed it (it just seemed so cheap looking). thanks, Brad_bb

If someone else can design it, I sure as heck can figure out how to fix it!

If the factory didn't use a fan shroud, then you probably do not need that to keep it cool. The fan shroud pulled air across the condenser instead of around it was its main purpose.

My suggestion is to make sure that the radiator is clean and that you aren't adding more heat than the cooling system can design. When the car is moving and you get more airflow, you can cool the vehicle. At idle, you have trouble. Check timing as well.

People fear change because it threatens what they know, or what they claim to know.

I don’t think Chevy ever put a shroud on any of their cars back in the day, even with air conditioning. They had a different fan with 5 blades instead of 4, but no shroud. Cars from back then had trouble keeping temperature even when new. Overheating was a common occurrence back then.
If it cools okay when you are moving, then airflow is your problem so a shroud should help. Here is a metal one from Classic Industries:

It says that shroud is for V8 core support with radiator in V6 position (in front of the core support). I have the V8 core support with radiator in the V8 position (behind the core support) unfortunately.

Summit Racing has a Danchuk #16626A, V8 in V8 radiator position. I put it on my 55, works good

What the previous poster said. I put that one on my car, it looks factory, and works very well.

Thanks, I had not found that metal V8, V8 shroud. Not sure if the diameter is small enough for stock fan but I just ordered it, so we'll see.

I do not have a specific recommendation; I have not owned a '55 this century. But, to function properly, the fan blade needs to 'sit' approx half in and half out of the shroud. So, the distance from the radiator to the fan blade will impact the 'depth' of any shroud you install (along with mating to the radiator and existing fan.

Air flows thru the radiator (bumper side to engine side) because there is a pressure differential. During driving at forward speed, the differential is supplied by out side air being forced against the radiator. At idle/stop and go, the fan creates a 'negative' pressure on the engine side of the radiator. A shroud increases this 'negative' pressure and 'more' flow results.

A fan with more blades (5, 6 ?) will provide 'increased' flow. But w/o a 'clutch' such fans are 'noisier' at higher rpm. Also, w/o a clutch, such fans will 'draw' more torque from the engine to rotate. Torque that could be used for other purposes (propulsion, a/c).

The 'clutch' (if used) also impacts the dimensional aspect of the installation.

Pick based on your priorities. But first I recommend you verify the radiator's functionality.

Just trying to be helpful.

Sorry about that. I didn’t notice it was for the radiator being the the 6 cylinder position. It looked like they had several options and I just chose the metal one. Here’s the correct one:
