Steve Posted April 9, 2009 Share Posted April 9, 2009 After having to remove my fuel rail to fix a fuel leak (the fitting is now welded so wont leak again ), i was going to remove the water feeds that go to the IAC valve and the throttle body whilst i have the intake off. Is there any reason why i shouldnt do this? Can i just blank the feed pipes off or should they be joined together to keep a circuit? Thanks Quote Link to comment Share on other sites More sharing options...
Wez Posted April 9, 2009 Share Posted April 9, 2009 I am planning to block mine off as well, its another job on the todo list Quote Link to comment Share on other sites More sharing options...
Steve Posted April 9, 2009 Author Share Posted April 9, 2009 Are you gonna block them off or join both of the pipes back together to complete the water circuit? Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted April 9, 2009 Share Posted April 9, 2009 I removed the 2 feeds on the throttle body, but left the IACV one in place. One length of rubber hose from the block to the IACV and job sorted Quote Link to comment Share on other sites More sharing options...

One length of rubber hose from the block to the IACV and job sorted Thats what i was thinking, so basically it keeps it as stock but without going through the throttle body (and IACV in my case).

Chris Wilson Posted April 9, 2009 Share Posted April 9, 2009 If you use the car in very cold, humid weather the removal of the water feed to the TB *COULD* cause it to ice up and *COULD* cause the throttle to stick open. Would / V / Could is for you to decide. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted April 9, 2009 Share Posted April 9, 2009 I once had a Volvo ice up its throttle body with the heater pipes removed, in a UK winter. Icy, foggy morning, suddenly it wouldn't come back down from 4000 RPM Refitted the heater pipes and never had this problem again. Nver seen it on anything else, since, either.

paul mac Posted April 9, 2009 Share Posted April 9, 2009 mine are off, the IAC is just looped through till i could be a**ed to do a proper job, i have had no connection to the throttle body for around 2 years, 1 year of that was daily driving to work in the winter (car garaged), i now have a "spare" car that i use for work so the supra doesn't come out in the cold anymore, i would be slightly concerned if the car was outside all night in the dead of winter and maybe left for a few days you could get icing problems, the IAC would not be to much drama as eventually it would defrost as the engine got warm but a sticking throttle is pretty scary, at the end of the day mines a pampered pet that lives in a heated garage, if yours is outside and you expect it to run reliably all winter i would leave them on Quote Link to comment Share on other sites More sharing options...
