Radiator fan ties
David Jenkins - 11/4/03 at 11:52 AM

As I've just decided to change my radiator I've discovered that I need a few of those push-through ties used to hold the fan against the radiator.

Anyone know where I can get a handful?

Any electrical or diy hardware should have a selection of different size tie wraps. Or the tool stall if you have a car boot or market nearby.

yours, Pete.

I was thinking more of the kind you get with the fans - it's a long "wire" made of plastic with a button on one end. You push the "wire" through and push another button over the end.

Sorta like this... <bad ASCII art alert>

The "wire" is very thin and goes easily through the rad's matrix and through the little holes in the fan mounting.

I've use the two I got with the fan and, once they're on, they don't come off intact!

cheers,

David

I can get hold of a few ties you can have as a freebie......

for example, I have 8mm wide by 380mm long - look like the tings the US army handcuff people with. Colour is black.

Also have some about 200mm long and 4mm wide.

Let me know if you want any. Liquid hospitality at any time in the uture could be a repayment

Steve,

Thanks for the offer, but I have hundreds of the conventional cable ties, in all sorts of sizes.

It's the specific ones I'm after...

Try calling the people who make the fan, suspect they will post some out, might even get them free being such a loyal customer.

Car Builder Solutions sell them, £3 plus £1.50 postage. www.nfauto.co.uk

Click on CBS products and they are about half way down the page.

Is it ok to use the ordinary cable ties then ? Won't the heat allow 'em to stretch ?


David Jenkins - 11/4/03 at 06:55 PM

HSD - thanks, I'll try them. Looking through my catalogues (now I'm at home) I see that most sell these ties, but at anything from £4 - £6.50 + VAT & packing!

Jonti - I don't think the ones I'm talking about will stretch - they're made from a not very flexible, tough plastic.

Cheers,

David

I wouldnt use plastic cable ties for this use but you can get some nice stainless ones but they are rather expensive at a pound each from my local factors. RS also sell them in bulk and i am presently thinking of a good use for some at work.

As stated above, there are special ties for mounting fans directly to radiators, but plain ordinary nylon zip ties do the job too.
The method is to pass a zip tie through a plastic "washer" (just a 19mm dia scrap of plastic with a small hole punched in it), and through the fan and radiator. Thread another plastic washer over the zip tie, then cut one of the "buckles" off a spare zip tie, and slide it down over the zip tie being used, snug it down tightly against the plastic washer/radiator, and snip off the excess zip tie stem.

It's a hell of a lot cheaper than the "proper" ties, and mine have lasted for 3 1/2 years so far.

Well cheers chaps I'll give it a go with me vanilla cable ties then. The washer trick is a good 'un too, stops u putting sideways pressure on the fins.. thanks Rorty

I used a rad from a volvo. These have a steel frame around the vertical sides.

I just welded four metal strips about 100mm long from the steel frame across the rad to the fan cage mounts. Before welding on, I welded some bolts on the strips for the fan.

This method puts no stress on the rad as its effectively 'surface mounted' the fan.

Am planning to go the cable tie route.

One question, do you need anything between the fan and the rad?

Dan.


stephen_gusterson - 15/4/03 at 11:34 AM

I used some springy rubber foam strip between the rad and the fan housing - stops rubbing and also sives some compliance if you are using a 'clamping' action as a cable tie would cause.


scutter - 15/4/03 at 03:37 PM

Thanks, Stephen was starting to fret for no reason.

I don't place anything between the fan and radiator. As long as the cable ties are fully tightened, their natural elasticity will keep the fan really tight against the fins, so no movement is possible anyway.
Depending on the shape of the fan shroud, sticking foam strips around it may restrict the size of the opening, thereby reducing its efficiency.
If you do choose to go with a foam strip, use the correct product (neoprene), as some of the "draught excluder" type foam strips will disintegrate in time, leaving the fan to move around freely.


stephen_gusterson - 16/4/03 at 12:45 PM

I used neoprene strip.

If anyone needs some, I can get hold of it.
