25th Anniversary Posted June 9, 2015 Report Share Posted June 9, 2015 Hi all I have a solid oem rad and a brand new alloy rad for a beams conversion, but is the alloy really the best one to go for? Link to comment Share on other sites More sharing options...
digs Posted June 9, 2015 Report Share Posted June 9, 2015 there was a big thread on this with someone doing test, came up with oem? in the site somewhere! Link to comment Share on other sites More sharing options...
25th Anniversary Posted June 9, 2015 Author Report Share Posted June 9, 2015 really?! I thought alloy rads kept the engine much cooler? Link to comment Share on other sites More sharing options...
_Chris_ Posted June 9, 2015 Report Share Posted June 9, 2015 http://www.celica-club.co.uk/forum/index.php?/topic/157717-alloy-rdiators/ Just to add a little info to the thread, the first alloy rad I had was part of a group buy & made by golpher which worked reasonably well. The second one I bought - and which seems to be the only design available - has a slightly taller core leaving little room for the top tank, hence flow is very poor as it only has about a 5mm gap to flow through. The second one I bought has only done a few hundred miles as the engine kept overheating and the block was cracked after investigation - which was cause & effect ? who knows. The rad is going for scrap either way. Link to comment Share on other sites More sharing options...
fletch Posted June 9, 2015 Report Share Posted June 9, 2015 Found my 50mm alloy rad great on my GT.larger capacity means fan hardly ever operates and never seems to need topping up unlike oem. Link to comment Share on other sites More sharing options...
digs Posted June 9, 2015 Report Share Posted June 9, 2015 Tbh though, if your not boosting not going to make much difference ? Alloy would look nicer ! How thick is the beams rad and the alloy one ? 1 Link to comment Share on other sites More sharing options...

Sherv Posted June 14, 2015 Report Share Posted June 14, 2015 For what its worth,I had a nearly newish rad in my gen 4,when we fitted the Beams we retained it..,we were doing away with the A/C to be fair,meaning there was now nothing in front of the rad so that increased air flow to the rad itself anyway.I also have a lower temp opening thermostat fitted.ive driven the car pretty damn hard at times and also spent time in traffic on way to JAE etc etc and the temp has barely moved from normal,somewhere just under halfway on my gauge.

A lot bigger than the ebay rads at least and bigger than the stock item. Link to comment Share on other sites More sharing options...
