Hallgeir Posted October 9, 2013 Share Posted October 9, 2013 Hello all. My radiator failed on me this weekend. Car is Discovery 2A TD5 2003MY. While searching for prices for a replacement radiator, I came across this. http://www.ebay.co.uk/itm/LAND-ROVER-DISCOVERY-DEFENDER-2-4-TD4-2-5-TD5-ALUMINIUM-ALLOY-RACE-RADIATOR-RAD-/390631351015?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item5af37162e7 Has anybody tried it? Will it give more cooling? I have asked the seller, but not gotten a response, is the radiator old style with both small connections fully open or new style with closed and restricted? Does anybody know this? Any better options out there? best regards, Hallgeir Quote Link to comment Share on other sites More sharing options...
Nigelw Posted October 10, 2013 Share Posted October 10, 2013 God knows but 42mm is wider than a standard rad so it is possible also I am told Aluminium is a better material for heat exchange. But I am a little lost on the cost. £200 is a little bit cheap me thinks! Quote Link to comment Share on other sites More sharing options...
reb78 Posted October 11, 2013 Share Posted October 11, 2013 also I am told Aluminium is a better material for heat exchange. I'm not sure that it is is it? I'm pretty sure there was a discussion on this in the international forum on the thread discussing HFHs v8 rad. Some of the more knowledgeable chaps suggested that heat transfer was more efficient in a copper rad. With the whole uprated rad thing, I'm of the opinion that unless you have a highly tuned truck that is overheating as a result of lack of a standard rad cooling capacity, then there is no point spending money on the 'uprated' ones. In a way, I have kind of proven this for myself by wasting a bit of money fitting an uprated heavy duty (4 core) rad from M&D to my mildly tuned 200tdi. It has made bugger all difference to the cooling. But, then it wasn't overheating before, so why would it?! I guess I just potentially have more cooling capacity that I probably won't need anyway!

My disclaimer was "I am told" but then again it could be that I read it in one of the comics that I subscribe to. I always thought the 200Tdi over cooled a lot of the time even with the standard rad.

Hallgeir Posted October 11, 2013 Author Share Posted October 11, 2013 Copper is more conductive than aluminium and could be a better option, but aluminium is cheaper, stronger and weldable. I dont think overcooling is a big problem, have removed viscous fan and fitted Kenlowe. When water is too cold the thermostat will close the radiator off? Have some tuning, de-EGR, de-CAT, de-midpipe, large intercooler, VNT and remap. Most of the time heat is not a problem, but cannot tow a heavy(2-3 tons) trailer uphill for very long before temperature starts to move. Is 42mm wider than standard? Thought that was just what the standard was? best regards, Hallgeir Quote Link to comment Share on other sites More sharing options...
Hallgeir Posted October 21, 2013 Author Share Posted October 21, 2013 Having received the radiator, it is neither the old type nor the new. Both lower connections are fully open, but no internal baffles. Does the baffle really matter? The restriction, is it important? There is a second restriction on the inlet to the fuel cooler so you would think the 1 restriction would control the flow. best regards, Hallgeir Quote Link to comment Share on other sites More sharing options...
