If you didn't have problems with old radiator, then stick with something similar.

Good point

It is true though. "Generally" speaking most manufacturers have the cooling system sorted to a degree.

The issue is idiots like some of us here including myself modify things causing overheating issues

It iis not easy to stay away from engine mods when you have a good diesel rig. The need for more power is an addiction.

I will be in the market for a radiator, real soon, so I recently spoke to a retired radiator expert. He recommended a copper/brass radiator unless you completely clean and flush the system. You need to pay particular attention to the heater core, because the iron deposits create a battery-like effect with an alloy radiator, causing them to fail quickly.

I just had to do the welch plug behind the power steering pump. It's an absolute PITA with having to pull out the pump, while managing to drop the new welch plug between the A/C pump mounting bracket & engine block(impossible to fish it out). I didn't know there's damn welch plug there, otherwise I would've replaced it last year.
The amount of rust crud that was coming out of the leaking welch plug was unreal, 'cos I only used a chemical bottle to break down the rust two weeks ago while reverse flushing it again few times. All this is old rust afaict 'cos with new coolant with distilled water should've stopped further rust. I'm still reluctant to use a stronger flushing chemical 'cos of the fear of more leaks developing from the chemical breaking down rust and much more.

Alloy radiators are basically aluminium alloy, aren't they?! Assuming that is the case, there shouldn't be any iron deposits?

What's wrong with your radiator?

Mine is a copper one by the looks of it. It's been going good for years since I bought the vehicle, regardless of cylinder head and engine block having serious rust buildup issues.

Mine is weeping from a corner, where it was repaired a couple of years ago. The iron deposits are the rust in the block and heater core.

My radiator (89 GQ 4.2 TD) was weeping when hot and under pressure (Electrolysis?)

It was repaired 2 yrs ago but I have now given up and put an Al alloy unit in as recommended by my 4x4 mechanic / specialist 4wd guy. He uses the same type in his rigs so went that way too.

Looking forward to another 27yrs of trouble free motoring.

Bundoora radiators cant fault it.
