Hi. I bought a new radiator, fan shroud, and fans for my ‘72 Chevelle. I was surprised to see that the shroud had no bolt holes for biltong the shroud to the radiator or the fans to the shroud. The shrouds that I have seen in the past have had nice riveted holes for secure fastening. Mine is just flat sheet metal. Seems strange to me. I called champion and was told they no longer supply bolting as many people have strong preferences on how this is done. My question to the group: is this normal for me to mark holes and use simple self taping sheet metal screws (no riviots or anything)? Any best practices to use?

thank you!

I put a 71-72 fan and fan shroud on my 69 and I don't recall drilling any holes.

The fan shroud mounting holes on my 70 are on the top plate, none in the new Champion radiator
I did have to drill two holes in the bottom of the fan shroud on the 70 because the new Champion radiator was too thick to use the original bottom clips to the core support.

It sounds like you are talking about an aftermarket electric fan kit?

If so, yes, many require you to fabricate your own mounts or buy them separately and “adjust” them as necessary

You should have come on here before you bought anything for some advise

That Metal Shroud will likely Heat Soak the Rad Core, which make Cooling Down the Coolant hard to do
and the unknown Efans maybe from China are Strong enough to Pull Air thru the Rad Core and A/C Condensor etc.
to keep your Car's Engine Coolant Cool enough while Driving on the Hwy or in the City

I thought he meant that the shroud was sheet metal at first but I think maybe he was talking about the radiator itself, not the shroud.?

Maybe both? He mentioned calling “champion” to ask about it and also buying a radiator, shroud and “fans” (plural) so I took it as he bought a whole aftermarket electric kit, but we need more specifics to be sure.

Hi. I bought a kit from Champion. Picture attached. The radiator fan shroud that needs bolted to the radiator is sheet metal and there are no holes (or supplied hardware). The ones I e seen in the past do have holes. That’s why I ask. I find it strange that the fans/fan shroud and radiator that I bought from champion all together and was shipped together, doesn’t have holes to mount it together. Strange...

I would return all that and buy a Champion Radiator 3 core and use the factory clutch fan and shroud... After seeing all the issues people have with electric fans convinced me to forget about electric fans and Pertronix points replacement sets for that matter..

Who/whom is the Manufacturer of the Efans ?

What are the Measurements of the Rad's Core ??

How are you going to Mount the Rad to the Support Panel ???

Do you have the Stock Top Panel for holding the Top of the Rad to the Support Panel ????

On the Bottom there should be Metal & Rubber Brackets to support the Bottom of the Rad !!

I would be looking to put a Plastic/Fibre Glass Shroud on that Rad
for either Efans or a Mech Clutch Fan setup
There are different ways to do that
BeCool and Flex A Lite sell Various Brackets for Mounting the Efans/Shrouds to a Rad

I have the same set up on my 69 with a 427 and have had no overheating issues. I used stainless steel machine screws with nylock nuts to fasten the fans to the shroud, I also made nylon spacers to hold the shroud off the radiator tubes so it wouldn't rub on them. I fastened the shroud to the radiator with stainless sheet metal screws. I also put each fan on a 70amp relay and used a Dakota Digital fan controller.

I have a Champion radiator in my 65' SS and had to remove the factory metal shroud off the core support. The rad is bolted straight to the core support. I called them this evening about a fan setup. I'm running a March pulley system and have 2 1/2 inches of clearance between the rad and the WP pulley. George told me that with a dual 12" fan and shroud setup I should be fine. If any interference I can attach the fan directly to the rad and return the shroud for a refund.
