Audi 100 radiator woes

[pimpdriver]

Right, the radiator on my Audi 100 quattro (2.3 NF engine, 1990 G reg) was leaking.

I have a spare off the same car (G reg, fitted with 2.5 litre Oettinger version of the NF engine).

Here is my radiator: part no 443 121 251N


Here is the radiator off the 2.5 part no 447 121 251G


Putting the two together, they are slightly different.






The overall sizes are the same (from the edge of the cowl to the water pipes), however on mine, the fan cowl included the contoured piece to fit inside the wing, and on the 2.5 one, the contoured piece is part of the radiator.

However, if you look at the mounting holes they are offset on the 2.5 so if I fit that radiator, then it will be offset from where the mounting holes are on my 100.

When I looked on ebay for replacement radiators, it seems that one should fit all 100s from 82-90 (ie. the Typ44 years)

Shall I just try it and see, or get one of the radiators off my other 2 spare cars (NF auto, MC manual)

they have the same radiator for all cars.
