Help required:

I am looking to put a fan shroud on my radiator to get a bit more efficiency out of the cooling system. No problems shown up yet but just being a bit pre-emptive. Has anyone got or know of a holden fan shrould that would work on an HR radiator and fan?
I have got a couple of later fibreglass/plastic ones but they are much too big, both in the fan size opening and also the width and height.
Thanks B

Funny you should mention this , we are in the process of making some to fit a stock radiator and grey motor combo at the moment, one of our members is an ex boily and he is going to do the design work , then I am going to have them laser cut and we are going to make 3 of them.

I know that is of absolutely no help to you but its the third time this week the subject has come up .......

Hey Blacky maybe you could make a stretched one😀. Fan hole would be similar, pretty much just wider each side of fan?

Funny, I was only thinking of this process the other day. Back when I was a young Harv, I did Tech Drawing at school. We learnt how to draw the transitions between a round and square object, like a square radiator and a round fan. The transition drawing would then act as a template to let you cut and fold the sheet steel to shape.

Sadly, I can't remember how to do those drawings any more. Think I can still remember how to draw third-angle projection though.

Cheers,
Harv

Yeah, centre of fan may be off a bit both side to side , up and down and fore and aft depending on engine placement

I think the plan is -

- cut a circle about 30mm bigger in diameter than the fan and tape it to the front of the blade

- measure to the 4 sides of the radiator to establish centre point

- measure back spacing from back of radiator to centre of fan
- make a CAD template :lol:
- transfer CAD design to steel sheet using Totally Extremely Xcellent Transfer Application :D :D :D :D
- cut out and fettle until it works
- once it fits, take to boilys and get them laser cut.

Mucking about with a Holden Shuttle fan shroud today. Probably should be silver soldering but went gung-ho with the MIG. More to do, but basic shape is there.
Picked up a Toyota W50 five speed. Next job after going through it with new bits.

Thats a spiffy looking grey motor you have there 8) 8)
Gazza - Western Wagon - and I had a play around last week with a shroud, he has ordered one from somewhere online and when it turns up we will keep going with it.

Grey motor is the one that came out of Project 2 and was reconditioned and modded up by Advanced Performance Auto in Sydney. I need to sell it as it will never be going back in. Just taking up space, but it does look nice. 😁

Shroud needs the centre cleaned up and bolt tabs welding on. And of course, seeing if it works!

From what i read the shrouds work really well, it will be interesting to see the result.

Rough job finished. It wil be a nightmare to change the fanbelt. Going to stick 1cm strips of black foam around the edges that butt up around the radiator.

Lovely - be interested to see the amount of improvement this makes

Me too Blacky.
Ute ran at a coolish 70-80 when moving but warmed rapidly to 100 when waiting at roadworks etc. I'm hoping to control that aspect. I had put a electric fan in front of aircon condenser already but havent yet tested its effectiveness.
