Talking to the radiator shop yesterday, they said no dramas to re-core my radiator.

Before I do though... I want to double check that I have the correct one to begin with...

Its a 3 core, and it appears to have the Natrad symbol on the top tank... Is this perhaps a replacement unit? Or did Natrad supply GMH from the factory?

Also this appears to have the two fittings on the lower tank for the auto trans cooler?

Did they all have these? Or have I got an Auto Radiator?

Natra were oe suppliers for ford/Holden Chrysler back in the day. You can still buy those natra ones new if you want although the bands will be hq-hz I will also be auto.

So if Natrad were OE suppliers, how do we know that this is an aftermarket radiator?

If they were original OEM then I doubt part of the deal would have been allowing them to put their logo/stamp on it.

Thats a point. The symbol would be hidden by the fan guard however. No different to Bosch/Delco Remy bits having there name on bits though.

Since this radiator is not suited to my needs, what is available new in copper that fits LH/LX? Some that Ive seen advertised all mention the side mounting points need modifying? Is there anything still available new that dosnt need modifying?

Did the LH SLR have a 2 core or 3 core radiator?

If the side straps on your radiator are ok then your could get them fitted to a HQ-HZ radiator. You could buy a used manual HQ-HZ radiator and take it to the radiator shop with your radiator and have it recored and the Torana straps fitted.

You may also be able to cut the HQ-HZ straps so they look like Torana straps. The main difference is that the HQ-HZ straps have provision for mounting the plastic radiator shroud.

Hi Brad

Can you post a pic of the part number plate (the one with the number ending with 66 on it) on the top tank.
National Radiators were GM's OE supplier so a Natrad (nee: National Radiators) branded radiator will probably be aftermarket not original.

Ive had a few new holdens of that era and there was never any stamping on the top? tank of the radiator. I take your point with ignition/electrical,carby and brake parts, but the radiator nope, shouldnt be any different to all the other parts that get outsourced.

Though its possible that GM turned to another supplier and the branding was allowed to sneak through on some holdens of the era, but I doubt it.

Yeah maybe I just nick the straps off this one and then just throw it at some local down at Munro Martin Park,..

Thats if the straps are the correct type? How do I tell? Or do those numbers say its a Kingo Radiator?????

I don't think any LH come with a 3 row radiator.

Without looking at the side bands closer, the one pictured first appears to be an after market non OEM for a HQ/HZ (with the clutch fan shroud trimmed down to fit the torana engine bay) auto (trans cooler) with A/C (after market option 3 row) and the thermo fan switch blanked off.

9945194 looks like a Holden part number and B - 8 should be the date code February 1978 or 1988 or 1998???
Most likely an aftermarket radiator though.

Natra or NATional RAdiators or the OE manufactures for your vehicle, that is a genuine radiator for aholden of that age, if yours was a manual from the factory it would of been fitted with a manual Rad so it is not the original one for your car but it is a genuine radiator. NATRAD is the franchise for NATRA which only real exists as a name now. adrad are about the only other manufacturer of those except or the china ally stuff, that have a adrad stamp in the same spot. Natra used month/year codes on their cores so the B8 would be Feb 78/88/98.

Good point above by Terra... I didnt think about this... Using a 3 core will not allow the use of the fan guard unless its lengthened, something I saw Napes_au do.

So Ill have to go with a 2 core radiator.

I see there are listings for 2 core V8 and 6 cyl radiators?

What are the differences??? Is the hose outlets in different positions on a 6 or 8 cyl radiator?

Hose outlets are opposite sides on V8 to 6cyl (6cly same sides as chev V8) and the standard 6cyl radiator has wider side bands making the core smaller in width.

Yeah it is. Terralx is correct, you used to be able to get a 3row h/duty in the v8 narrow tank as well as the standard two row small tank v8. In not sure whether that was a torana option or kingswood option though.
