Rather than splash out on a one off rad, I have found a polo one that is bigger than the standard bike one and will also allow me to put my oil cooler directly under, problem is the bike rad has a pressurised cap on and also a feed to the expansion tank and also a feed to the thermostat housing, the polo rads do not have a cap or the 2 smaller outlets I need, what are my options???

I have a rad from a polo in my westfield; think its the one from the first generation 1.0l polo. Afaik everyone uses them; even highly tuned ones. They are alu and very light.

They come standard with two main connection (think its 32mm), one vent to the headertank (8mm i believe) and one M22 hole for the fanswitch.

If you get a header tank from a scrapyard you should be fine.

what about my other current feed from rad to thermostat housing??

Can you put a T piece in the hose near the rad to the thermostat?

Got any pictures of your current set up or the new rad?

I assume that the connection from the termhostat is to get the air out? If so, it should be routed to your header tank. Most header tanks have one outlet for linking to the main pipes and one for de-airing. You can use T-s to link up all the high points in your system.

On you chassis question; I don't know the indy design in detail but Westfield have a special S-curve hose in their online shop for it. Perhaps that is of use?

Haven't checked your supplier but I do advice you to check at your local parts supplier or the VW dealer. In the Netherlands they are quite competivive on price. I paid 84 Euro's for my brand new rad at VW dealer.

hope it helps.

Buy a rad cap that does not have the pressure spring (or remove one yourself).
Use this as the polo rad cap.
This will cause the small pipe from the neck to be open (and will leak), but connect this to your header tank.
This will act to bleed off any air and help your rad fill faster.

if you could be bothered to post links to the pictures you want us to look at, then I would be bothered to look at them and advise you...

However, it appears all you need is a header tank with a pressure cap, connected to the thermostat housing and also the bottom hose..

Below you can see a picture of a polo rad with oil cooler underneath..



And a header tank

Here's my 2003 R1 cooling layout with a Polo rad...
