Re: Radiator Help

This is what I've decided to do with the Sportster, the rad is imported from the US, bought on eBay from these guys: http://stores.ebay.co.uk/USA-Speed-and-Restoration (very good service from them arrived next day with the fittings I asked for)

It's a 19" x 22" x 2 1/4" ali rad which should *just* fit in the nose cone of the Sportster sticking down underneath about 8cm - however that is higher up than the steering rack and the sump. It might need a bit of reshaping to clear the steering column but should just fit.

See attached some pictures comparing it to the standard face lift E30 325i rad (this is a tag bit bigger than the M10 rad I'm currently using).

Re: Radiator Help

I've plumbed in the new radiator now. Been for a 45 mile drive today, and it's very warm out. Temperature hovers just over 80 on the gauge most of the time. At low speeds or stopped it does go up a bit. Highest was around 88 where it stayed nice and still at traffic lights. When we got back I left it on idle on the drive way and the needle on the gauge never moved.

On one of the hills where before the temperature go noticeably and quickly now the gauge stays where it is a bit over 80, probably around 83 - 84. Which is excellent.

So on the whole it's sorted it. It could probably do with a bigger fan to move more air through the rad at low speeds / stopped if the outside temperature is even higher than today.

I've attached some pictures, there a load more on my website:
