Well.... after reading the Big T's post a little while back regarding the danger of the fan shroud rubbing through the aluminium radiator cores on GU's and thinking to myself "better check that out", it happened. Green blood on the driveway. Bugger.

Upon removal and inspection, it turns out there's a pinhole in the ali radiator. Missus takes it to Natrad and the quote is.......$1,400!!!!! "you can't fix / weld an ali core radiator. Top tank is stuffed too." Strewth!!!

My questions to the brains trust are, can an aluminum radiator core be properly repaired? If so, does anyone know who does this in Perth?

Also, does anyone know of a good aftermarket replacement radiator for a 1999 4.5l petrol (TB45E) Nissan GU Patrol? I would prefer a traditional brass job for the obvious reasons. (BTW I'm aware of the PWR ones, they are about $1,100 from memory - must be something cheaper out there!)

Thanks in advance.

I cant believe the prices out there.
This is really becomming a joke...what a rip off. I've said it before...seems the 4wd owners are really getting whacked hard for parts and repairs.

Personally, I'd check out some wreckers, see what they charge and when you finally get a replacement radiator, spend some time fixing the rubbing problem from occuring again. Damn rip offs.....hate them with a passion.

I remember seeing an ad for a mob that convert alloy to brass for a fraction of the cost. I saw it in a just 4x4 mag can't remember their name but worth a try.

Hi there,
Sorry to hear of the woe.

Try Desert Cooler radiators, he is in Vic, and does exc ellent work, don't think he can repair your alloy one, but I would say he can certainly supply a suitable non-alloy replacement. He custom manufactures them for all types of vehicles, he has done 4 for me, 3 were hot rods, and 1 for a big block chev VN commodore in 5 core. Price was very good too, he advertises in the performance and hot rod mags regularly.
Hope it helps,

g'day V8,
try a motor bike radiator repairer, im in s.a. and have used a bloke in vic before, im afraid ive got no further information than that on him. (busted the radiator over 4 years ago) the radiator was fairly messed up and they welded it up and straightend it right out. if that fails, try a specialist alloy welder, might be cheaper than 1.4k!!!!!!!!!!! then again maybe not.

A mate of mine had his alloy rad repaired after the fan went into it.
No problems afterwards.
Worth checking out.

Had a pinhole in my GU radiator also and Natrad quoted me a similar price for a new one saying aluminium couldn't be welded (I have since been informed that it can be ... I think special rods are required?). When I persisted enquiring about repairing options they finally came up with the option of some special "glue" which is applied with heat. They won't guarantee it but I went this way and have had no problems since. Have done Googs and Border Track since and no signs of problems.

I took the radiator out myself and dropped it in to them. Cost....$40. A lot cheaper than $1400! I guess the trade off is reliability and a risk of problems in a remote area. I guess Natrad don't offer this option readily because they make more money out of selling you a new radiator.

Removing and replacing the radiator took a while. Even though they were still ok while they were easy to get at I also replaced the top and bottom hoses and all fan belts and the old ones are now in my spares kit.

Gday all

You could always try a product called “Bars Leaks” It is also a corrosion inhibitor seen this stuff in action on a 4 Core Tractor radiator, It had 3 Big holes in it and it stopped them all to our surprise.

Welding a aluminium radiator, if you can get access to a high frequency Tig Welder you could have a shot

Firstly, a big thanks to everyone for all the help and suggestions, the forum comes through again!

It's fixed!!! Both areas where the fan shroud had touched were ali welded for $50. I removed the radiator in 20mins and put back in tonight 15mins. Gotta be happy with that compared to $1,440.

The bloke who did it said he uses the welding rods from the guy at the Royal Show (as was mentioned above). He does motorbike radiators too (also as suggested).

Will look into getting hold of a reasonably priced brass one at leisure now.

Thanks again guys, owe you all a good drink or ten.

True Davoe.

Did get a quote from Magic Nissan when phoning around, a new factory radiator is $963 inc GST ex warehouse (2hrs).

Better than Natrad by a long way, but not as good as $50!
