Water pump pulley bolts

Oh and just FYI 3/4 bolts were too long. 1/2 inch with a lock washer should do the trick.

 

If your not wanting to keep an original appearance ;a lot of folks use the Champion 2 row rad. I use that unit about 7yrs w/o issue cept, the drain plug contacts the cross member; I had to trim away some lip on the member to open the drain cock easily. I didn't use plastic ties - I attached the fan to rad w/ flat metal strips and bolted fan to radiator. Others here, have some other suggestions they may offer.

 

I have seen the Champion ones while searching lately. Otherwise never heard of them. Two rows is probably enough. Thanks for the insights.

 

Two rows is enough! I run AC and two is enough for me.

 

Is this it? https://www.championradiators.com/2-row-Ford-Maverick-radiator-20-driver-1971-1977

I have a 1970...

 

Yes, that's the one!

 

Geez they want a hundred bucks for the aluminum shroud, plus another 30 bones to ship it.. There has to be another way to mount one of these electric fans.

 

If you can weld just make your own shroud. That is what I had to do when I made a custom offset shroud. Not hard just time consuming.

 

i just measured with a toothpick until it poked through the back side of the pulley with the spacer removed...took the original bolt to home depot and found a matching size, yet shorter. was easy.

heres a vid i did showing what i did.

 

use a relay. my vid shows how.

 

You can make your shroud and don't necessarily have to weld. All u need is some flat metal strips, bolts, n sheet metal.
It goes w/o saying, a few basic tools and little ingenuity.
Here is what mine looks like...

 

That's probably a little more my speed. I haven't tried to weld anything since high school and also I don't have a welder Lol.

 

Why have a shroud at all? Most electric fans have their own shroud. Anything addition simply blocks air flow through the radiator once the car is moving. I mounted my fan directly to the radiator. Also helps remedy electric fan to water pump clearance issues. It kept my 351W and now 302 cool in the staging lanes and heavy traffic.

 

It's just a more solid and secure way to mount the fan to radiator than using those plastic zip tie things.

 

I could tell the difference when I added the shroud to my car. I drove for a year or so B4 I made the shroud. I put a piece of light weight cardboard on the side the fan didn't cover - cardboard wouldn't cling to radiator. After shroud was added cardboard clung to radiator -- That tell's me I gained air flow at lower speeds. I need all the airflow I can get, running AC in 90+ temps, waiting for long periods, like mile long train crossings. The cardboard test made a believer out of me!
