Swampy442 Posted August 30, 2016 Share Posted August 30, 2016 Good, because 1.3bar is crazy pressure, stock id only 0.9 I think. Also is it a fake HKS? Link to comment Share on other sites More sharing options...

Chris Wilson Posted September 1, 2016 Share Posted September 1, 2016 Your heater matrix may not like a high coolant pressure should the temperature make it rise higher than stock. You can't buy new genuine matrices any more either. Link to comment Share on other sites More sharing options...
a98pmalcolm Posted September 1, 2016 Share Posted September 1, 2016 Arn't all after market rad caps 1.3 bar? All after market rads use 1.3bar caps. Even a TRD one is 1.3bar Sounds like a crap Rad Cap mate. My Mishimoto one leaked so I bought a blitz one from Paul and its been perfect Link to comment Share on other sites More sharing options...
Chris Wilson Posted September 1, 2016 Share Posted September 1, 2016 Just check the HKS one hasn't got any debris under the little sping loaded one way valve if you want to continue using it. The valve allows vacuum in the rad to pull fluid from the "overflow" reservoir. Link to comment Share on other sites More sharing options...
Jellybean Posted September 1, 2016 Share Posted September 1, 2016 OEM standard opening pressure is 0.95 to 1.25, minimum opening pressure of 0.8 HKS do a 1.1 bar cap for the R33, thats what I use Link to comment Share on other sites More sharing options...
