Radiator Hairline Crack

Hello

Today I noticed a hairline crack at the base of the radiator filler neck, it trickles a small amount of coolant when driving and for a short while after until the car cools down. it's not losing heaps of coolant but don't want to be driving and have it open up and lose my coolant I'm not going to drive it until it's sorted in case it goes bang big crack.

Just looking at advise as to what I should do,

Is it worth removing the stock one and taking it to a radiator place and get the top tank replaced? $150-250

Or buy a brand new koyorad oem replacment radiator $250 http://www.ebay.com.au/itm/RADIATOR-NISSAN-SKYLINE-R33-R34-93-2001-MANUAL-VEHICLE-KOYO-RADIATOR-/200449233351?pt=AU_Car_Parts_Accessories&hash=item2eabb491c7

The car is used 99.5% on the street so a big expensive racing radiator would be overkill and unnecessary. And don't want a cheap china alloy one either

Anyone been here before what would be the best way to go?

Buy a new one. Fix it now and it might just break in another spot later.

Get a new alloy radiator now and less likely to have problems in the future. I bought a Greddy radiator when mine split. Best thing I think I could have done

Yeah I'll get a new one, not really keen on replacing the top tank idea.

I've looked the Blitz 41mm alloy rad and koyo alloy 53mm they are 500-600$ Not sure if it's overkill and a waste of money. Do these fit like oem?

Genuine Nissan.

What do these cost? Couldn't find anything online not sure if anywhere would have one and be able to have it to me within a week

This is dodgy as but I had a mazda bravo way way back when and the top tank split the whole lenght, being young and broke I pulled out the aerodite and put a healthy coat over it till I could afford a new one, 4 years later I replaced it cause it looked dodgy not cuss it was leaking :/

Solder up the crack or just get a replacement stock radiator from your local shop. It should last another 15 years. I just use stock radiators in my car with the RB30 and it doesn't overheat on track days.

Just fixed a Cracked Honda S2000 Gearbox case that cracked around the drain plug in 3 places (told son not to overtighten it 1000 times before putting the plug back in and what does he do?) with JB Weld. :)

I have heard people are also using it on radiators, but i can tell you his gearbox is not leaking and it saved me from pulling the box out and getting it welded back up again. (or replacing the box)

Dodgy as hell but it worked, dont know about the next gearbox oil change though......

The radiator top tank is plastic remember.

I was advided against repairing it when mine cracked. Especially if you are happy to just to get a cheaper than Jap brand radiator. Sounds like it will be fine for what you need. If you want to spend some money than the Greddy radiator is great. Fits perfectly and shroud fits on nicely

Really up to you but

I'm going to replace the radiator hoses to, would it be a good idea to replace the thermostat while I'm there?

The only Greddy radiator I can find online is $1099.!?

Would there be any cooling issues with the koyo oe replacment? Anyone used one?

If you have the standard clutch fan and shroud (assuming fan works fine), you're better off getting something that can use the shroud.

Take your pic, then either buy through there, RHDJapan, Import Monster, Nengun, or Jesse Streeter.

The top tank in my Bravo was plastic and it held up for 4 years with aerodite :)

Just looked like arse :/

Are these instock in aus or need to be sent from japan?

They all say factory air duct cannot be used with this radiator. I'm still using factory airbox is this a problem

What about fenix rads http://www.ebay.com.au/itm/Nissan-Skyline-R33-R34-93-02-Heavy-Duty-Alloy-Fenix-Radiator-/171117111768?pt=AU_Car_Parts_Accessories&hash=item27d75fe9d8 they look quality?

They get shipped from Japan.

You should be concerned about the shroud more than the air duct, but if you want to keep the duct, get OEM.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
