Xtreme Motorsport Aluminum (inium) Radiator

[Kalamat88]

Hi all,

Browsing through Black Friday deals as the capitalist sucker that I am and came across this behemoth. Decent price, too.

Has anyone installed this? Might be some slight fitment issues to wiggle in, but in installing this, will it throw any codes or faults?

My ChatGPT friend mentioned the following being an issue:

• It lacks a probe fitting and purge, as listed — meaning if your original cooling system relies on sensors (e.g. temperature sensor, coolant level sensor) or built-in bleed/purge features, you might need custom solutions or additional parts.

Can't see any reason why it would be a problem. Coolant temp sensor doesn't sit on the radiator and stock rad doesn't have a purge/bleed valve either.

Looks like a straight swap, maybe some minor modification(s) to get it to fit properly but looks like it'll line up.

Stock radiator is usually fine though, unless you're in a hot country, though I've not tested in super hot (30C+) conditions on a regular basis!

I don’t see why you’d need such a radiator unless you’re rallying or full-on racing. I get that you live in a hot climate, but fitting the air conditioner radiator would be tricky. The car is built to run in places like the south of France and Spain, so if you’re having temperature issues, check the fan sensor for corrosion, the relays for fan speed, and the lower hard metal water pipe for leaks. Nissens offers perfectly fitting air con (940125) and water radiators (67284) for very little money.

Pardon our interruption...

I was looking for something like this for mine too from Toyosport,as i understand it will only take more time to heat up and more time to get warmer and warmer on heavy track use (or if you are turb'd/supercharged),only buying it as more sturdier than plastic and obliviously looks better lol.

To answer to the OP i cant see any issues fitting the one you linked,bit expenisve though for what it is.

Hey guys- really appreciate y’all’s comments.

Frank: Yeah, that’s what I was thinking (hoping), too. This one is 80 mm taller and 50 mm thicker than the OE radiator but I’m fine if I can shimmy it in there.
Thanks- didn’t know we didn’t have a purge on the OE radiator, good to know.

Also, while I do live in a hot country (southern Greece), it doesn’t see track time. It sees some Sunday cruises but mostly this is our road trip car; traversing mountains, long highway trips.

Turkie: Ah, good to know about the AC radiator. Hmm, it is overkill for sure. The logic behind putting this in is that a complete radiator flush is on my mind for the near future and while I’m at it, put in a brand new radiator that’s all metal. It’s probably from the trauma I had dealing with my E36 M3 that when it was first released, was 90 something percent recyclable- so much plastic: t-stat housing, water impeller on the water pump and of course the radiator. It was a ticking time bomb from all the horror stories I read so I always want to have the security that I know my cooling system is top notch. So yeah, no cooling issues, but just something I’m a bit overzealous about.

On another note, while bigger, it’s just as light if not lighter than the OE radiator. 3 kgs vs 3.9-4.0

Veiron- Definitely does look better haha. So putting one of these bigger radiators in will take the engine longer to heat up? That’s not good as it will cause premature wear in the long run… or maybe run a higher temperature t-stat..
