2 core versus 3 core radiators

[Bloodyaussie]

I am interested in the difference in 2 and 3 core radiators and have been told that 3 core are really only any good for towing and that with a lot of 4wding they clog up to easily.

I am looking at a copper/brass job but am unsure which way to go.. I would like any input from people who have actually fitted one.

I have to sell an injector pump to pay for it (so want to make sure I get this right) and will be selling a near new alloy radiator ($80) that is shit...lol.

I have a 3 core and I reckon it's great. It dropped my temps heaps and only on a very long Hill on a hot day will the temp gauge get to half.

But I know a lot of people prefer two large cores, like the Aussie Desert Cooler brand.

I'm pretty sure no one has issues with copper 2 core radiators.
Unless your running a high power setup in the near future I'd just go a stock unit.

You dont want your motor running too cool.
who knows maybe you will tow a camper in the future,
If I had the opportunity to up grade I think I would go a 3 core
Go speak to Norm [the big yid] at Aussie desert coolers he'll
have a radiator that suits your needs

I have had concerns about running too cool as this can be an issue... as for going to Aussie desert coolers that is way out of my price range.

Thanks Winnie I did not know you bought a 3 core and good to hear from someone that has one.

How is it in the freezing cold months out your way?

Running too cool? That is what a thermostat is for, it opens and closes to regulate engine temps.

IMO any turboed td42 should have a basic radiator upgrade.

Can you run to cold by upgrading the radiator?? Unless you change the thermostat to a different temp a bigger radiator should only aid in ridding high heat easier but still within stock engine temp ranges

But heavy duty 2 core or 3 core as I know with 3 core there are smaller channels as apposed to a 2 core with larger????

Just following this for now till I get a chance to reply

Sorry to butt in / hijack thread, and excuse the lack of my mechanical expertise... Just quickly why could this be a problem? I just assumed the cooler the engine runs the better ?? Hence a 3 core rad would be the go ?
