Sundaydriver Posted July 11, 2014 Share Posted July 11, 2014 Hi, So I need to replace the rad, as it's very slowly weeping. I am planning to do a few odd trackdays, perhaps four or five times a year I guess, unless I get totally hooked ! I may look to more bhp with mods at some point, with the k series. Task: 1- alloy rad 2- upgrade/renew fans 2- triple return/bypass mod ? ( can you tell I'm not sure ha ha ! ) 3- PRT 4- temp sensor 5- renew necessary hoses Been advised to sort above while doing the job, anything I missed off ?

Martin R Posted July 11, 2014 Share Posted July 11, 2014 We need some clarification on triple return bypass mod? Link to comment Share on other sites More sharing options...
DeanB Posted July 11, 2014 Share Posted July 11, 2014 Paint your towing post, or if it's badly corroded get a stainless one. Mine has rusted right through! Link to comment Share on other sites More sharing options...
Sundaydriver Posted July 11, 2014 Author Share Posted July 11, 2014 Dean, thanks, good idea ! Triple heart bypass ... Adrian at Corinium Motorsport suggested I consider an updated rad, I kind of understood his explanation , kind of . He says it forces water to take the long route through the rad , due to Blanks , maybe he's meaning a triple core ? Link to comment Share on other sites More sharing options...

Martin R Posted July 11, 2014 Share Posted July 11, 2014 No need for a race rad. A standard ally one will do IMO. Link to comment Share on other sites More sharing options...
@ndy Posted July 11, 2014 Share Posted July 11, 2014 This is what I fitted - CLICK HERE Never had temperature problems since fitting even on some very hot days on track Link to comment Share on other sites More sharing options...
Sundaydriver Posted July 12, 2014 Author Share Posted July 12, 2014 Thanks Martin. Kosmo, might be me, but link not working ? Thanks again for your help :-) Link to comment Share on other sites More sharing options...
MilesH Posted July 12, 2014 Share Posted July 12, 2014 Dave, you won't need a triple pass rad, they are not advised for road cars. As Martin said you just need an uprated ally one like in the link above or a similar one from Eliseparts: http://www.eliseparts.com/products/show/84/224/aluminium-upgraded-radiator/ It gets rid of the plastic end caps on the standard rad which are known for bursting and is also a larger capacity with extra cooling fans. I've ran 230bhp off one for 4 years on track and never had an issue. p.s. it's Neil at Corinium Motorsport not Adrian Link to comment Share on other sites More sharing options...
Sundaydriver Posted July 12, 2014 Author Share Posted July 12, 2014 Miles, cheers, costs are stacking up ... ;-) Link to comment Share on other sites More sharing options...
scatty Posted July 13, 2014 Share Posted July 13, 2014 I put an uprated ally one on mine. Again, I had the same question and was told the triple wasn't really needed... It was either from Elise parts or Elise shop. One was a bit cheaper than the other. Both good places to buy from.. Link to comment Share on other sites More sharing options...
kayj_prod Posted July 13, 2014 Share Posted July 13, 2014 I just replaced mine with the ally EP one. Quite happy with it. My original rad was fine, but I had to replace the heater matrix due to a leak and figured the rad was probably near end of life too. I changed the front end hoses too, though I fitted PRT a couple of years ago so the back was done. (PRT is way easier with the rear clam off.) Maybe change the coolant tank while you've got the system drained? When you change your rad, be prepared for the inevitable seized bolts. Worth buying some new C clips and SS bolts before you start the job... and a new hack saw blade! Link to comment Share on other sites More sharing options...
Sundaydriver Posted July 14, 2014 Author Share Posted July 14, 2014 Thanks Kayj, Scatty. Anyone upgraded their fans from standard ? Link to comment Share on other sites More sharing options...
kayj_prod Posted July 14, 2014 Share Posted July 14, 2014 I thought about it, but now seeing how efficiently it deals with bringing the temperature down at the rad, I'm glad I didn't bother. ...but I know you're thinking about the track too.

Sundaydriver Posted July 14, 2014 Author Share Posted July 14, 2014 Well I've checked the max/min level, at cold before a run out to Shelsley Walsh on Sunday, and again tonight. So, a round trip of around 100 plus miles, with some spirited driving. There's no change in the level. Link to comment Share on other sites More sharing options...
