Richard, I've never seen or heard of your radiator being used in an OZ T3, so may not meet required specs. It sounds to me like its volume and surface area is inadequate, you may have a problem running at correct temperature, usually midway or a tad less on temp gauge.
Both the OEM (48mm) and BEHR (40-45mm) radiator overall core width equates to the width of the coolant tubing. Except the tubing is shaped like a series of flattened circles, running horizontally, each separated by about say 12mm.
From memory, there is a difference between those two brands by about a factor of one as to the number of horizontal tubes.
Maybe your old original radiator, flushed and tested professionally, might be the better solution.

Subject: Re: [Syncro_T3_Australia] RadiatorHi Ken, that mirrors my experiences (well except my original was cooling fine, it was suspected it had a leak, which it didn't, so I have it as a spare)
When you measure the core, what are you actually measuring? The Thermex one I have, the core was 30mm, but the tubes were ~12mm diameter and round, so not only were there fewer tubes, the surface area is also much smaller.

Hi ALL,
This topic never fails to confuse most of us, not helped by Just Kampers and Tooleys questionable offerings.
JKs ... is a very poor joke at 30mm core thickness, in fact this radiator ought only be sold in cold climate markets elsewhere:
From memory, someone here, possibly Scott, had to return one to JKs upon discovering its "thinness".
Tooleys ... BEHR part no. 8MK 376 713 631, the model quite a few of us have purchased, has a core thickness approx. 40mm.
My old VW OEM stamped radiator 068 121 253 E that I took out, has a core thickness of 48mm.
Along with installing the BEHR radiator, I took the opportunity to fit a replacement baffle set:
http://www.gowesty.com/search- results.php?search_phrase=radi ator+baffles
Also fitted a new radiator temperature switch. Bit sus though, think it was Chinese. Tested it first, found to be in working range.
Also fitted a sponge strip on the horizontal top of the radiator, similar idea as shown in ETKA parts catalogue schematic.
Observations: OEM vs BEHR.
OEM core is around 8mm thicker than the BEHR. Big OEM tick.
OEM quality of core construction is clearly superior than the BEHR. The core's coolant flow tubes look stronger and with larger volume and the separation foils are way way more robust. Big OEM tick.
The BEHR is an exact replacement fit for the space. Big tick.
Located vertically midway on both sides of the OEM is a metal bump strip to protect the core when fitting/removing the radiator. These are missing from the BEHR. I relocated them to the BEHR.
Fitting the GoWesty baffle set was a good idea, especially given two originals were missing! Obviously because when the Prestige A/C system was installed, they removed one vertical baffle that otherwise would be in the way of the A/C pipe reticulation they installed!
With a bit of thought, patience and experimentation, I successfully modified the baffle just enough so it again fitted quite well in the available space, despite the interference of the A/C pipework.
Prior to installing the BEHR, the OEM tended to run hot, especially when waiting at traffic lights, this scenario with 50-50% G12+ coolant and distilled water.
After installing the BEHR with same coolant mix, plus with full baffle set installed, the temp gauge is now reading too cold. If this persists through upcoming summer heat trial, then I'll drop back to a 40-60% mix.
So in conclusion, I really can't say for sure which of the components contributed most to the change in the temp gauge reading. Radiator? Baffles? Both? Winter temperature? But clearly, the removed old OEM radiator is a clear winner in terms of build quality and core thickness. But then again, the BEHR seems so far to be doing the cooling job well.
The other thought in hindsight was to instead, have the old OEM professionally cleaned and tested and if OK, try a refit and trial. Maybe too fiddly though.
I'm keeping the OEM for now, if anyone wants more info about it, let me know.
Cheers.

Hi I spoke to Richard Tooley yesterday from Tooleys and he measured the Behr radiator's he has in stock (x4)068 121 253DG and they are 43mm thick.

Hi Paul,
Thanks for the pics, they worked just fine this end and spurred me on to re-check and so snap a few pics as well.
So pics confirm your and my radiators are original OEMs with VW/Audi stamped logos and same part numbers.
My vernier shows the core thickness at 46.80mm, and not my previously stated 48mm. Need my glasses checked!
The other pic showing 45.00mm was the width of the indented frame at the end.
All this now suggests the BEHR core is around 3 to 4mm thinner than the OEM.
You can also shine a torch into the thermostat hole and see how much, if any, residual crap has built up on the inner surfaces and perhaps blocking the tubes ... a bit of a guide as to general health.
Interesting difference is your OEM radiator core and frame appears to have been painted black, whereas my OEM is bare aluminium all over.
Cheers.
Ken

I got mine from Tooleys in Sydney. Highly recommended. Peter from Port
Noted Phil. I made sure it was the thicker one when ordering as someone else had an issue with them I believe. But it was all good and it arrived quickly and is now happy in its new home!! Peter from Port.
