[urq] Dialynx rad vs Stock rad w/ Aux rad delete

[Maurits Jonkergouw]

Thanks everyone for the replies. I've decided to go with the aux rad and a new stock radiator. The mint condition Nissens radiator I already had from the CoupeQ. has been 'upgraded' ie. my local radiator-shop welded the extra 2 headers for the aux rad and relocated the small header to the coolant reservoir: 40 euro's... now THAT is a cheap radiator :-)

I guess if you're in the process of getting a new exhaust manifold, rebuild turbo, oilcooler-lines and both radiators, you might want to look carefully how to spend your money ...

Can't wait to get my hands on my 'refurbished' quattro.

The aux rad was deleted a long time ago (also leaked) and never noticed increasing water/engine temps, not even during high speed travelling in summer. Although I have to say during this hot summer my exhaust manifold cracked at several places, but that's just coincidence :-)
