Better radiator.

[Carolyn]

I put a replacement 'Coolparts' radiator in last year.  It kept sucking up air (as they do).  Despite replacing both O rings for fatter ones and doubling up on hose clamps, it was still doing it.  A couple of weeks ago I replaced the top O ring again, but it's still playing silly buggers.

I decided to bite the old bullet and go for a slightly more expensive radiator.  I sourced the one MR2 Ben sells, but for a better price.  It's £20 more than the Coolparts one.

It arrived this morning.  It has proper 'wing-nut' type bleed screws as standard (rather than the flat-headed things on the Coolparts one), which is encouraging and the plastic end-tanks seem more substantial. It has a lable saying AHE Cooling LTD  #TO2334

Another case of just going for price ain't the best idea.

And here's a couple of pics:

Nice work, be interested to see how you get on.  Re: the air, would that explain the varying levels in the expansion tank, with the Coolparts ones fitted?

Probably.

Hi Carolyn
Did the AHE rad come with a pressure test "certificate"?

Didn't see one.  I'll look in the box when I'm next in the workshop.
