Today I found a hole in my radiator, so now I think its time to get it refurbed with an extra core, does anyone know how much this will cost?? and where in the Midlands I may get it done????.

TIA

I googled and found these over your way. My comp radiator was rebuilt at Serck in Nottingham in 1990, but I had one done locally. I would estimate about between 80-100. The one pictured in front on mine was done by Mansfield Radiators in 2006 apprx not 2002.( http://www.mansfieldradiators.com/ ) and he did a better job than Sercks. My how time flies..

These rads are two core and Mansfield Radiators inferred then that three core would only be a little cheaper than two core 99.

Talking to a well respected Radiator man in London, he told me a radiator should never need three rows if it was designed with two - the only reason a radiator struggles to cool, is if it's blocked, so two new rows will be more than sufficient. Three rows could mean you struggle to get the car up to its running temperature - especially in the winter.

I didn't have mine done but talking to the guy who would have done it I got the answer that what he called a "sports core" would only increase the cooling by 10-15% max, as the tubes would be smaller and closer together. This doesn't increase the surface area very much and can slow the throughput of air. It was also about twice the price of a standard recore.
This was Bryan & Son, Tunbridge Wells. They did a nice job on the rad of a friends Chrysler Valiant. Big rad, not that cheap though.

There is plenty of room for an extra core in the Saab rad. I have only run an extra core on modified engines with an electric fan. The rad ends need to be in good condition, the core can be scrap. It should cost around 80-120 to re-core with an extra row. As said it only will give around 15pc extra cooling, but that is a fair bit extra. A good electric fan with thermostat control mounted up against the rad can help. This will only come on when required, so helps with warm up time, along with the rad blinds Saab sold.
Its not all to do with surface area, you need a temperature differential, so the same fin area positioned in a large flat area will give better heat transfer compaired to the same fin area positioned in a row.

"Woody,just one more daft question,does it matter what condition the rad is in?????"

If the side tanks are in good condition and the top and bottom rails are OK they will be cleaned and transferred. If the rails are damaged/rotten it may cost more to repair these parts.
I don't have any experience of three row rads. Having a pusher fan, thermostatically controlled, is possibly a better option than the extra cost of the three row, as Richard suggests.

Sure you must be related to Dr Who. Looks like it has appeared out a time warp from the factory in Trollhattan.

Thanks Woody! Maybe, Saab might have done it like that. The rest is mostly original.

In reply to Simon's remarks, I had an extra core put in mine about 2 years ago,c ost about 130 I think, it does stay nice and cool in the summer, but as Simon say's it does struggle to get up to temperature in the winter.
