sdsurf Posted January 18, 2008 Report Share Posted January 18, 2008 Will it fit? Quote Link to comment
pope_face Posted January 19, 2008 Report Share Posted January 19, 2008 I think the short answer is... No. As far as I know, you need a 521 specific rad, although IIRC one from a 510 will fit... and seeing as a VW Rabbit one will fit in a 510, it should follow that it'll fit in a 521. Someone else might be able to verify... Do you need a replacement one? If it's super cheap (or free) you might be able to make it work... Quote Link to comment
datsunfish Posted January 19, 2008 Report Share Posted January 19, 2008 I would say dont bother trying.The 521 radiator sits damn close to the fan and the 79 is wider which will likely set it on a higher spot in the core support and put it further towards the radiator. I would persue the rabbit rad.Jegs catalog has custom fit rads for around $160.At least they used to.The 510 and 521 radiator are the exact same thing so if a place cant get a 521 ask them for a 510..

sjeff64 Posted January 19, 2008 Report Share Posted January 19, 2008 I have been running a rabbit radiator in my 521 for many years. It will never over heat on you if you use the stock fan. I have run mine with no fan on the motor for several year with just an electric fan with a on off switch. now that my front end is straight enough I can put the stock fan back on!!!and use the electric as a back up here is the article I used : http://www.dimequarterly.tierranet.com/articles/tech_rabbitrad.html Quote Link to comment

datzenmike Posted January 19, 2008 Report Share Posted January 19, 2008 The '79 is also probably a 3 core and will be thicker front to back. That's why the '75 an on rad support is not straight across, but bulges to the front to make more room. The L20B rad is almost certainly wider too. Just remember that anything can be made to fit, that isn't a drop in. Quote Link to comment
shane_lxi Posted January 20, 2008 Report Share Posted January 20, 2008 My friend patrick (acesn8s) is running a scirrocco radiator. Fits nice, kinda spendy, but it's a good looking radiator :D. Quote Link to comment
banzai510(hainz) Posted January 20, 2008 Report Share Posted January 20, 2008 buy a 510 radiator for a 521 . 620 will not fit due to the bottom tube near the alternator Quote Link to comment
