Based on the thread title, how many radiators have you gone through ?? What brand ??

@Datatek There's two sensors on GEMS, but one dual sensor on Thor.
- Previous owner put a new rad in mid-2021.
- Replaced the above late-2022 with https://www.allfourx4.com.au/Radiator-suitable-for-Range-Rover-P38-V8-EFI-from-1999-on-PCC106850/
- Replaced the above late 2023 with a local shop's radiator. Looks very very similar to the above.

Hesitant to buy another, unless it's a full alu, until I've gotten to the core of the issue. Especially if this loss of power/limp mode thing is back.
 
Looks ok, but if it's leaking in less than a year, must be crap quality. As said before, leaks allow the coolant to boil, so fix these first.

Power / Limp issues need diagnostics, but unless the ECU gets silly temp readings, I can't see it being related.

Soneone on here got an all ally one from somewhere that seemed decent. Cannot recall the name. Regazzi? @Mark Piercy might remember.
 
So I got that heater hose off and it looks like the pipes are just fine :banana:
As I was wrestling with the hose, I could see coolant seeping out of it- it was split. Looks like whoever replaced it last just use a regular hose which was too small. The correct hose should be slightly flared at the heater-matrix end.

By some miracle I was able to find the correct hose at some wholesaler that was only 15 minutes from my house, otherwise it was going to cost me over $100 Aussie dollarydoos to get it imported from the UK :vb-groan2:

This is what I got https://www.ebay.co.uk/itm/335376708715 (PCH118830) it says hose-heater-out, I need the heater in, but it was the same part number for both out and in so... /shrug


In other news, I got under the car at night with a UV torch to try track down the other leak, and turns out it doesn't seem to be coming from the radiator after all. But rather, something dripping onto the bottom of it somehow. I couldn't definitively tell where another leak was, but I could see a bit of dried coolant on the lower part of the hose that goes from the thermostat to the water pump. So perhaps that might need replacing as well.

Dust with talc, follow the trail back ...

Got one from direnza in the UK. Great shiny box but the quality of the welding looked like it was done on a Saturday morning after a few drinks the night before!! That suggested to me that these rads are bought from the the same company that builds those sold on ebay for example and direnza pay them to add a panel with their name on into the fabrication process. It has held up tbh and does its job but if your a stickler for a decent finish you may be a tad dissatisfied 👍

Can you remember which member was doing a lot of towing and was buying a triple core one from somewhere? iirc he said yhe original LR one was double the Nissens one but he'd found something bigger than that?

Thanks for that one i need a new rad my Nissens one has started to leak only been in about 15 years :(

My Nissens rad has been on there about ten years, maybe a few years longer but has been fine so far, although it did struggle up Lodge Hill when towing a 3 ton digger.
