psymon Posted March 15, 2006 Share Posted March 15, 2006 Fitted my Koyo rad today, anyone know how much more coolant it takes ? Also does it matter which way the tranny cooler has to be mounted, vertical or horizontal or doesn't it matter ? And thirdly how much extra tranny fluid do I need to buy ?

psymon Posted March 16, 2006 Author Share Posted March 16, 2006 Anyone? Going to Mr toyota to buy some type iv but don't know how much to get Link to comment Share on other sites More sharing options...
Alex Posted March 16, 2006 Share Posted March 16, 2006 Keep going till it's 100% full, how much you need is dependent on how much you flushed out of the system...but if the stock system need 9L's for a full flush and the Koyo rad is bigger I'd have bought a 3rd tub of 4Life... The tranny fluid only goes into the thick pipe running through the cooler...I'd expect you need a litre or 2 depending on how ling the lines are that connect it to the 'box. Toyota T-IV....flush the autobox sump at the same time. So I'd get 5+L of T-IV to fill both.. The orientation shouldn't matter but I'd mount it so the fins are horizontal as that looks normal...if you're mounting it straight on to the wind.

tango Posted January 17, 2007 Share Posted January 17, 2007 Hi Im also interest on the KOYO radiator? how much is it, is it for the TT Auto? Link to comment Share on other sites More sharing options...
psymon Posted January 18, 2007 Author Share Posted January 18, 2007 There is not a specific Koyo rad for the Auto. If you change it you need a tranny oil cooler, installed too. Most of the traders offer these Si Link to comment Share on other sites More sharing options...
Sheefa Posted February 21, 2007 Share Posted February 21, 2007 I will have a MKIV store Tranny Cooler available shortly for cheap tango if you need one? I also have this Rad fitted. Bloody good so far. But then it's only winter! Link to comment Share on other sites More sharing options...
