Polo rad
David Jenkins - 7/4/03 at 08:03 AM

Has anyone got a picture of a Polo rad in a Locost? As I said in another thread, I'm trying to decide whether to use a Polo or Micra rad, and I'd like to see all the options!

Also, which Polo is the one to go for? As far as I can tell, it's a 1 litre Mk1 or 2. Is this is correct?

ta,

David

David.

Dont use a Polo rad.

They usually have holes in.

mumble, mumble,...

Too many daft beggars on this web site...

grumble, mumble...

Not a locost, but a Westfie1d with a (hole free) Polo rad (I think an early 1.0)


David Jenkins - 7/4/03 at 12:36 PM

Thanks, F.W.

That's really useful - doesn't look too hard to fit, either.

What engine is that? I can't see enough to make it out.

And is that expansion tank as big as I think it is?!

David,

I am using a Polo rad in my Locost. These two pictures show the radiator in place but with nosecone and grille fitted. I'll try and remember to take a photo without the nosecone and send it to you. Eurocarparts were selling them for 33 quid, and it was listed as Polo 83-90 1.0 to 1.3 carb models.

HTH,

Eddy


David Jenkins - 7/4/03 at 01:29 PM

Erm... what photos?

I would like to see a photo without the nosecone though.

Also (being cheeky) can you tell me the width and height? (inches or cms - don't care which)

cheers,

David


Alan B - 7/4/03 at 01:44 PM

David there are links on Eddys post.

Note to Chris....links showing up differently would be nice if possible...


David Jenkins - 7/4/03 at 01:48 PM

Oh, yes... I see them.

(I usually do an underline around any links I post).

So the VW rad does fit, but it's still a close fit.

Still like to know the height & width, if anyone can tell me.

Ta,

David


zetec - 7/4/03 at 03:30 PM

Just checked, bit tricky with nose cone on but measured 47cm wide 35cm high. have a look on my photo section I think I put some on.


eddymcclements - 8/4/03 at 08:06 AM

David,

Sorry - forgot to take photos last night! Just wanted to add that it's not too tight a fit - there's probably an inch clearance all round, and the close fit is a good thing because it'll force the air to go through the rad instead of around the edges. I may even build a flange round the rad to seal it to the nosecone, so that ALL the air has to pass through.
I have an ex-Citroen Saxo "sucker" fan mounted close behind the rad; no cowling. The only reason for using this item is because it was the newest supermini in the scrappy that weekend. I've connected it up to a 12v supply and it creates a HUGE draught. I guess these Euro cars have to remain cool even in a Turin traffic jam, and chilly ol' UK isn't such a problem.

Regards,

Eddy

(makes mental note: must take photo, MUST take photo!)

It is a 2L Zetec that has been messed about with a bit to produce approx 200bhp!

The expansion tank is the dry sump oil tank which has now moved to the passenger footwell.

Don't know the height, but I think the width is 380mm. There is a wider rad (430mm) available.

I'm convinced!

If that radiator can cope with a 200bhp fire-breather then it will have absolutely no problems with my 100bhp X-flow...

David


David Jenkins - 12/4/03 at 06:08 PM

I bought a Polo rad today, using FastWestie's part number, but I'm wondering if they've given me the wrong thing...

The one I've got is 52cm wide across the whole thing, and there's no way it'll fit into the nosecone.

Can someone who's fitted one of these rads measure it up (e.g. EddieMcC) to let me know who got what wrong?

My suspicion is that they've got their part number mixed up...

Ta,

David

Hi David i have a polo rad in my car and it is a fairly close fit. I got a photocopy of a couple of pages from a factors catalog and have them in front of me now.
The smallest polo rad has a core size of 381 height 322 width and 34 mm dept, the mountings are two lugs top and bottom with a centre distance of 500mm which would equate to the 520 total width.
I used two bottom points into a couple of brackets and made two other brackets to attach to the tapped holes for the fan mountings at the top.It is mounted at an angle of about 15deg with the bottom forward.
The larger rad has a core size of 480 h x322 w x34 deep., and a total width of 600 across mounting centres.
I will try and take a photo of mine tommorow after work and post it tommorow night if it will be of use to you.
I have just been and measured my rad it is core zize 380w x 320h and total width of 480 across the tank ends. It came from a 1989 1100 polo so almost confirms to the catalog sizes.
Paul.

Sorry it's taken so long. I've taken a couple of photos without the nosecone; you can see them here and here.

I've also dug out the Eurocarparts receipt - their part no. is 203440491 and ref: 86712125 3E.

Hope this is some use.

Eddy

Damn!

It looks like I've got the smallest Polo rad - and it's not going to fit. I might have stood a chance if I was able to mount hard up against the front of the chassis, but there's a hose connection in the way.

Looks like I'm going to have to sweet-talk my supplier for a refund...

David


zetec - 14/4/03 at 03:05 PM

Mine looked the same at first but I managed to get hoses to fit OK.


David Jenkins - 14/4/03 at 03:26 PM

Trouble is, I can't get the nosecone over it!

The nose is really well made, with a good lip at the rear which makes it rigid. I can't "wiggle" the nose into the rad, and the glassfibre is far too rigid to "pop it over".

Also, the inside of the nose tapers quite sharply, which doesn't help.

I'm just going to have to find another rad...

B*ll*cks!

DJ

P.S. A question for Jasper - you've got Triton GRP - which rad are you using?


bob - 14/4/03 at 07:16 PM

Jasper is using the micra rad i found (sort of) for him,it came form a D-reg 1.0 micra that was being used as a skip.


David Jenkins - 15/4/03 at 07:11 AM

Thanks Bob...

Although I bought my rad from "German, Swedish & French", I did notice that they had a Datsun/Nissan catalogue on their shelf.

Might be able to negotiate an exchange instead of a return...

David

Postscript: I just rang "G,S & F" - they're happy to take the rad back & refund my money (Phew!)

My Polo radiator (see further up this topic for part no.) is 470mm x 330mm x 50mm. It is a plastic-and-ally construction, with the header tanks (actually mounted at either side) crimped into place. It has two rows of coolant tubes. The dimensions I have quoted are overall - not just the core size. It fits quite easily within the ST Motorsport GRP nosecone.

I believe the larger radiator is from a MkII Golf, and is more rectangular in shape - the Polo one is closer to square.

David - e-mail me directly if you need any further info - I'm not always on this site.

All the best,

Eddy


David Jenkins - 15/4/03 at 09:59 AM

Polo Mk3 Rads £55+vat £5 Carriage

if anyone is interested


poloace - 15/4/03 at 10:50 PM

Polo rads are this is my area of experince! I'm on my 5th one,

The mk1 & mk2 are smallest most compact a mk3 has small mounting pegs that would get in the way. Also MK3 GT is bigger . Some Mk2 have an intergral header/fillar cap on one side but for a locost application they will be to low to be used.

Very light and in my experience not that leaky.


dutchsuperseven - 19/4/03 at 07:00 PM

Me, myself & i used a golf mk2 radiator (1.3 1984?) in my machine. There should be a pic. in my photo archive. It fits well and the schrouding even accepts a ford fan.


David Jenkins - 20/4/03 at 04:32 PM

Eddy (and everyone else)

Panic over! I managed to swap my original wide Polo rad for a narrow one, VW part no 86712125 3E. This is the 470 x 330 x 50 sized one.

I've been annoying my neighbours this afternoon, angle grinding off my old brackets. I'll work out the new ones tomorrow, weather permitting.

Incidentally, I compared the size of the original Escort rad with this one - the Escort one has roughly 300mm x 20mm extra surface area, but the Polo one has a lot more pipes in it. I expect the Polo one to be more efficient!

rgds,

David

Oops! One more question - what fasteners were originally used to hold the rad? I can see the holes in the plastic, and I guess that they used fairly large self-tapping screws. Is this correct?

Northy - 26/8/03 at 02:12 PM

Sorry to drag up another old post, but I'm just about to sort the cooling out with one of these rads.

How does it all plumb together? Do I need a seperate header tank? If so where do I plumb it into? I'm not using a heater, so that should make it a little easier.

Cheers,


ned - 26/8/03 at 02:18 PM

Northy,

I know its for a 16v (but shares the block as 8v) but SBD have a diagram on their site of the plumbing for rad, header tank etc. wonder if it's of any use to you?

Ned.


Northy - 26/8/03 at 03:39 PM

Ned, be a good chap and put it on here!

PS You'll have U2U in a mo.

Cheers


ned - 26/8/03 at 03:41 PM

sorry, it's a bit on the large side, but you did ask!

Ned.


Northy - 2/9/03 at 02:34 PM

Sorry to drag this up yet again...

Could someone with a Polo rad tell me what connections it has on it? Is it just a large one at the top and bottom? Any other smaller connections? And could they also be so kind as to tell me the diameter of them?

The problem is I have a chance to get some decent silicon hoses at the weekend, but won't have the rad by then.

Cheers


Mix - 3/9/03 at 07:36 AM

Rad has only two hose connections, both on the same side, one top and bottom, outside diameter 32mm, (this is the diameter of the pipe not the retaining bulge).

Mick


Northy - 3/9/03 at 09:09 AM

Bless you! Which side are they on? Can the rad be fitted 'upside down' so to speak?

Cheers


eddymcclements - 3/9/03 at 01:36 PM

My Polo rad (see further up in this 5-month-old thread for details) has 32mm top and bottom connections on the near side of the car. It also has a small take-off for a bleed hose at the highest point of the rad on the same side. I can't see any other was of ensuring air is expelled other than by utilising this connection.

Eddy


eddymcclements - 4/9/03 at 11:01 AM

I thought I'd already posted this link to my radiator in which you can see the small bleed hose. Not connected to anything in this photo, though.
