Radiator repair

Recommended Posts

Well, my radiator sprung a leak yesterday. I will probably take it to a radiator repair place tomorrow if I can. I am just posting this to ask you guys is there anything you would like to share about this job? I've never had a radiator repaired before but it seems simple enough. Is there anything you've learnt from experience that I should keep in mind though? :ermm:

I heard once that the 280zx grilles had another core when compared to 240 version. Maybe it might be worth coverting to 280zx considering how warm the weather is at the moment? Apparently the bolt holes on the zx one have to be lengthened for it to fit a z - I wonder if this would be the same for a k?

Just an idea..

Hey Lachlan.

Don't be surprised if you have to spring for a new radiator (or at least a new core). By the time a radiator starts to leak (unless it's from a stick or other puncture) there's a good chance that the rest of the core is pretty close to shot.

I'd be budgeting for a new one (good chance to upgrade to a heavy duty one)

Sorry to be mr negative about this :nervous:

time for aluminum radiator lach!!! im going to get a 22x19 aluminum griffen radiator when im ready to buy it...its about $208 shipped US money, i think thats a great price for what you get.

im not sure what material your radiator but im guessing cooper or brass, pretty much im guess they are going to weld the leak shut with special copper or brass rods.

i have an extra nissan 280z radiator if you want it but i think its cheaper to get it fixed, not sure what shiiping would be towards your way but if you want it let me know.

im getting my aluminum radiator at www.summitracing.com

Ahh, probably not a bad idea at all guys. My current radiator is stock from 1992 IIRC. If I could get a replacement radiator that fits and works better than stock for a decent price, I'd go with it. Any ideas where to start? Can I just go to a local radiator shop for this or would it be more specialised?

If Australia is like the USA, your Radiator shop can install a thicker core (more cooling tubes) into your upper and lower radiator tanks and mounting plates.

you can take it to any radiator shops/place and you can get them recored and you can tell them to make it thicker extra core or something if they dont have a similar replacement.

Aluminum would be great light and more efficient. i would get one when I have the $$$

try PWR radiators I heard they are really good they will make any dimension you want.

Let us know when you've replaced your radiator.

Hi guys, I rang up several places on the Gold Coast and the best deal looked like upgraded to 3-core for $375.

That sounds like a fair bit..!? Especially when you say you can get an aluminium radiator for $208 US...

Are aluminium radiator replacements a bolt-in thing?

Not usually. The one I saw a while back for "$200 something US dollars" also required a mounting kit as well. Then different hoses were required (or at least ONE different hose)

I might stick with the upgraded 3-core one then. Does 375 (293 USD) sound like a reasonable price? To recore it without upgrading was 300 (235 USD).

Well, I paid $250 USD about 4 years ago for a 3 row recore on my car. Radiator work was warrenteed for 2 years by the shop. It is still in excellent shape.

OH, Aluminum radiators have horizontal tubes, rather than vertical tubes. Nothing wrong with that, but they are quite different from OEM.

Hey Lachlan why dont you volunteer to be the 240K guiney pig for swapping radiator? :)

You can start measuring and go to your local wreckers and see whats similar

You can always buy a radiator hose and cut/modify it and also use a stainless muffler tip as a joiner free from exhaust places for offcuts

Then maybe just fabricate new mounting.

Might be a cheaper alternative.

If I would to spend AU$375 for recore i would just add more $$$ to upgrade to aluminum.

Goodluck!

Hey Lachlan.

I paid $300 for a 3 core rad for a Datsun 1600 14 years ago. This was from Z-16 in Sydney. Based on that, $375 for a H/D core for 240K is pretty good.

There's a guy called Turbovan at the Ozdat forums who'se just fitted a 1996 BMW 7 Series V8 alloy radiator in his SR powered 1600. This radiator cost him $400 brand new, but it also needs special mounts made up, and a pressurised overflow. Looks like it also has engine oil cooler fittings built into it (I'd have to confirm that, but that's what thye look like to me).

A couple of pics can be seen here:

Food for thought

Edit: Looks like you can't see the pics. You might have to head over to www.ozdat.com, and look for the "My now project" thread towards the top if the General Datsun Nissan Discussion. The photos of tha radiator are on page 4 of 6 of the thread.

Lachlan,

I used a 3 core radiator in my 240K last year, this was sourced from an R30 Skyline automatic.

I bypassed the trans oil cooler tank though and fitted a 91 Magna trans oil cooler.

To fit the R30 radiator you'll have grind/cut some off the mounting frame away so that it will fit into the radiator support panel, then drill a couple of holes in line with the K's mount holes.

For me this worked a treat, spent $50~ on a good radiator.

Hi guys, just wanted to add closure to this thread - I went for a standard recore - just 2 row as I don't really need anything more. Was $300 and was very quick. I had a bit of grief getting it back in (did up a clamp too tightly and squashed the outlet pipe on the bottom of the radiator :stupid:) but it's all good now. Thanks for all your help guys,
