what radiator should i get for the mk1 to keep it cooler as i have a new engine for it?

A Mk1 GTI rad is fine for pretty much anything - especially with little, to no, accessories on the motor

are they easy to find?

ohh this motor has accessories! 1.6 bored to 1.8 with some headwork and my side draught weber

I mean power steering and a/c, which put a further load on the motor

You'd only run into issues if you have big compression with that setup. The top-fill radiator will run fine

Is a mk2 gti rad much bigger or better? curious to this myself.

Something you could do is get a twin fan shroud, not sure how much difference they make though.

ahh i see!
yeh i dont think there is big comp, it may be a bit higher however

i think a good flush should see the radiator working fine again hopefully

The Mk2 8v one is a fair bit bigger than the Mk1 top fill.

I have a twin fan setup on my Mk1 GTI rad, which seems to work well. I couldn't really say if it's any better as I haven't run it with a single one, though.

I used an Audi 80 1993 Model Radiator and twin thermofans for my Mk1. Its almost perfect sizewize and contains heaps more coolant than a Mk1 rad.

I rarely saw any Mk1s overheat due to small radiators, even the standard ones work fine if the rest of the cooling system is up to scratch.

I squeezed a twin fan Cordoba radiator into my MK I, but then I also put the cordoba motor in there too!

the top fill radiator is the same size as the gti/diesel ratiator too, its just that the gti/diesel radiators have separate expansion tank to make it a proper air free system and so is a little more effective...

and so yes, the diesel and gti radiators are the same.

I sourced a heap of Mk3 TDI radiators years ago. brand new. They worked a treat as when competing the temperatures would soar while actually thrashing my Golfs. Normal and hard street driving proved no problems with the standard radiators, at least down here in Tas.
I bought up all the stock of the radiators from the place that had them and have used them all up bar one. I am keeping that until I know Gunters fate.....
The later African Golfs had bigger radiators in them. 81 on.

As mentioned, a Mk1 GTI rad is more than enough! Does the job fine on my 20vt Mk1
