Noz Posted May 11, 2019 Share Posted May 11, 2019 Can anyone advise where I should pick up the water from and where I can feed it back into. I'm thinking to tap into the water neck that enters the engine from the top water hose. Any experience would be great please. Link to comment Share on other sites More sharing options...
kwalker705 Posted May 11, 2019 Share Posted May 11, 2019 I tapped into the top water neck for a return , Then on the lower back side of the water pump there is an outlet that i used a feed. I pulled out the barb fittings and drilled and tapped both to NPT threads and fitted adaptors from NPT to -4AN. but if you still have the barbed fittings out of both you should manage to run a hose direct.

Noz Posted May 11, 2019 Author Share Posted May 11, 2019 Thanks mate. Is the water neck not cool water going into the engine from the rad? Link to comment Share on other sites More sharing options...
kwalker705 Posted May 11, 2019 Share Posted May 11, 2019 Thanks mate. Is the water neck not cool water going into the engine from the rad? Just checked the coolant flow diagram. It is indeed feed on the water neck and return on the back of the pump...... Link to comment Share on other sites More sharing options...
Noz Posted May 11, 2019 Author Share Posted May 11, 2019 Legend. Thanks mate! What type of lines do you use. Just normal braided? Link to comment Share on other sites More sharing options...
kwalker705 Posted May 12, 2019 Share Posted May 12, 2019 Legend. Thanks mate! What type of lines do you use. Just normal braided? I use Black nylon braided rubber line with -4AN fittings. Fitted a heat sleeve to the lines close to the turbo/manifold though as the nylon braid doesnt tent to cope so well with heat. Link to comment Share on other sites More sharing options...

SupraTRD_MK4 Posted May 13, 2019 Share Posted May 13, 2019 Thanks mate. Is the water neck not cool water going into the engine from the rad? This would be wrong mate. The flow from the water neck is hot side water. As the coolant flows from the top of radfiator from this point down to the bottom of the radiator, it is cooled and then fed into the water pump side as cold water. You can even feel the difference and logically that is how it is as hot water/ steam would rise and cold water would not. Link to comment Share on other sites More sharing options...

Noz Posted May 13, 2019 Author Share Posted May 13, 2019 Because I have the 2jzge. Could I then use the disconnected pipes from the throttle body? Looks to be the same locations to me. Link to comment Share on other sites More sharing options...
