Hey all,

I'm Looking to upgrade my 260s radiator and like everyone I've noticed the aluminum ones on eBay. Can anyone who has one make some comments on their performance and maybe clarify the different ones that are available (2 and 3 core radiators have the same pic on the eBay ads)?

I found this one thread where they have one good review, hoping to add to that before I make the purchase.

Chinese cheaper than say Desert Cooler, PWR is most expensive.
Few i know have used all three, no issues at all.

For more effective heat transfer from engine to water, do not use ethylene glycol, ie the usual common anti freeze coolant, since wgen, in this country do we freeze!
Instead
Use product like Redline Water wetter, or Penrite Sin coolant, these do not contain ethylene glycol, are dafe to "dum"on a race track, and actually cause more efficient transfer of heat from hot metal into tje eatwr, and cause better air cooling as itasses through whatever radiator you use. It also makes our original equipment radiators work better!

I've one on my 240Z. Paid $180 delivered. Good product tho had to drill new mounting holes on one side to mate up with the rad. They were about 5-8mm out. No problems with standard clutch fan and have made the car run noticeably cooler.

I fitted mine and blew 2 heater cores before i realised it was the radiator not releasing pressure at the cap. It was clearly a manufacturing fault but the ebayer i bought it off refused to do anything about it because it was out of warranty.

I replaced my original radiator with a 3 core eBay radiator, apart from the 2mounting holes being out on one side by 1-2mm, mine has been going strong for the past 6months.car even runs cooler :). I run mine with twin thermos though.Overall I would recommend it or the price , I think mine was roughly 200 to my door.

Good thread!

So there appears no doubt hey are better and then even better again if we use Redline Water wetter, or Penrite Sin coolant.

So now where is the best place to buy them.  Are the local sources just as cheap as evilbay?  Which evilbay stores are good and which should be avoided?  maybe some store links could be posted of people's positive experiences?

Ash, do you sell these?

I have no idea Benny, I'm pretty sure he said 12, I just ran with it. I could have been suffering from shock!

I run the 'champion cooling' 3row with shroud and twin electric fans. It has been great on track and in peak hour traffic. The only issue is the shroud and fans are 8mm away from the water pump pulley, so if you go with that option there is zero chance of running the oem fan.

PWR is just too pricey for me  :o

12 core?  :-\
Computer says no.......

I got on from evilbay for $215. ASI brand
triple core, needs mods to fit.
Fins are very soft, so be careful.
Seems to be ok for me.

I had one built by "Alloy Race Radiators" in Dandenong Vic, all up was around $650 with a 12" Craig Davis fan all mounted ready to go. Has served me well for the past 4 odd years with the only problem (my fault!!) was blocked with dried up sediment from being in storgae while I was doing the engine conversions.. Flush your rads before you store them away!!!!

Get of those Chinese ones with the make an offer option. Offer way less and they'll take it. Redrill the mounting holes when you get it and you're laughing.

I have one of the ebay chinese ones in my car.
Cant speak to the performance side of it, as i have never had it running properly yet :-[
Quality is good, very happy with it, mounted up well.
They have a good finish on them and are very easy to polish up to a brilliant shine, if you so desire.
Delivery was good too.

When i was part of the Gemini forum, they did a big group buy of them, about 30 or so in one go.
Of those 30, there was 1 that had a slight weeping from the core, was replaced no worries.

Make sure you check/change the radiator cap to an appropriate cap to suit your application, eg, recovery system or not, pressure ect ect

Hey gents!

Thanks for all of the replies.

I get the impression that they perform well and will aim for a 3 core unit. I will ditch the mechanical fan and use thermo fans on the new radiator.

Please keep posting your experiences with the ebay radiators, as I'm sure this will be a useful reference for others.

Cheers!
Steve

Hi Steve, I use one on my track car (not a Z) but had to convert it to triple flow to make it effective. Not a difficult process and now it performs really well. The overall quality was very good (for the price) but the supplied cap was rubbish as others have noted.
I picked mine up from the eBayer, and then another turned up at my door a week later! So at effectivly $80 each, I'm really happy.

Ok you guys got me going as my car runs warm some times. So I find the biggest Chev radiator and it's the same size as my old metal one for $300- off eBay.
My question is, would an alloy radiator same specs run cooler than a metal one?
I intend putting in an oil cooler soon but should I do the radiator at the same time?
Cheers
