Labubre Posted August 18, 2021 Report Share Posted August 18, 2021 Hi there, Must change the radiator on my L16 510. Any validated radiator to recommend? Electric fan could be considered. Thanks Read about Champion radiator Found this one at https://www.protuninglab.com/ra-dat51068-2.html Thanks for advices Seb Quote Link to comment
datzenmike Posted August 18, 2021 Report Share Posted August 18, 2021 That is for the 521 which does have the L16 engine. I think they are the same size as the 510... probably fit. Well if you can find an old VW Rabbit radiator from the late '70s...http://dimequarterly.blogspot.com/2011/09/tech-how-to-installing-aluminum-vw.html Quote Link to comment
chukar Posted August 19, 2021 Report Share Posted August 19, 2021 Check out Koyo radiators. They seem to get good reviews from folks on ratsun and 510 Realm. Not cheap but it's supposed to be a nice radiator. Quote Link to comment
Draker Posted August 19, 2021 Report Share Posted August 19, 2021 Champions crack. go with the koyo. Good fit, need to space the standoffs with a few washers. Lower radiator hose can be tight but works. I have two of these. Quote Link to comment
banzai510(hainz) Posted August 19, 2021 Report Share Posted August 19, 2021 I have a champion but a 3 core you will need to put a 1/4 spacer between the core support and the radiator. Electric fan is not needed unless you live in the south of France. I believe the KOYOS need a spacer also as the radiator will hit the upper lip of the core support I have a OPL brand radiator(looked same as a Champion) and was bad from the start I had to run a 160 stat in it if anything higher it leaked really bad. My Champion I got now is better then the OPL brand. KOYO is expensive $$$$ 510 and 521 use the same radiators Quote Link to comment
Labubre Posted September 4, 2021 Author Report Share Posted September 4, 2021 Guess i will go for a 3 core chanpion CC487. Had a look at CHRRacing (they have a web site), but not sure about bulding quality, no feedback in Europe... I do live in south of France, and yes can be hot...but not as much as Cali i guess Quote Link to comment
Labubre Posted September 16, 2021 Author Report Share Posted September 16, 2021 Hi I will finally go for Koyo rad HH02598 for my 510. Before taking the pretty expensive plunge (will buy in US = ship + VTA = €€€), i did take a look at radiator dimensions and also check within angine bay for the fitting... Looks like a tight fitting! For my peace of mind, can anybody share installation feedback of this rad? No surprises??? Thanks Quote Link to comment

For my peace of mind, can anybody share installation feedback of this rad? No surprises??? Thanks I've got two of these installed. The areas of concern are the lower rad hose can be tight to the alternator pulley. Use a shorter belt if needed. The second part is that the standoffs that connect the radiator to the core support need to be shimmed out about 4-5mm. It's very minor, use a few washers. It's a great radiator. 1 Quote Link to comment
Labubre Posted October 14, 2021 Author Report Share Posted October 14, 2021 Here is my koyorad installed Perhaps you will see on last pic above that my mechanic choose to cut metal a little bit behing grille on passenger side, matter of pulling away the rad from the alternator. He also had to cut lips around the grille from inside engine bay to get the rad as close as possible from the metal. It worked...so i am a happy guy! Quote Link to comment

iceman510 Posted October 18, 2021 Report Share Posted October 18, 2021 (edited) Photos working for me as well. You may want to look into sealing around the edges where the radiator meets the body. Gaps there allow air to pass through that does not go through the radiator and reduces cooling. Edited October 18, 2021 by iceman510 1 Quote Link to comment
banzai510(hainz) Posted October 18, 2021 Report Share Posted October 18, 2021 If he has a 3 core I would not worry about it in Cool England Quote Link to comment
