Tricky-Ricky Posted March 12, 2007 Share Posted March 12, 2007 Can anyone explain the purpose of the water pipe bypass arrangement in the pic? http://www.imagestation.com/picture/sraid225/p942cda9fa035fa5a4b2b93834ceaa970/ea5a4c9c.jpg Quote Link to comment Share on other sites More sharing options...
Andy-No-Knee Posted March 12, 2007 Share Posted March 12, 2007 It is supposed to cool the rear piston as some think that it gets hotter than the rest due to it being the last in the line. Dont ask me how that bypass works, as it looks like it is taking hot from the top of the rad rather than cold from the bottom. Quote Link to comment Share on other sites More sharing options...

I think this was a problem on the MK 3 but solved on mk4 Quote Link to comment Share on other sites More sharing options...
Andy-No-Knee Posted March 12, 2007 Share Posted March 12, 2007 Well they also do it on the 1JZGTE so you may be right. But that is what the water bypass pipe looks like. Quote Link to comment Share on other sites More sharing options...
Pete Posted March 12, 2007 Share Posted March 12, 2007 Wouldn't this affect the flow rate and therefore decrease the efficiency of the water system? Quote Link to comment Share on other sites More sharing options...
