Day881 Posted May 15, 2017 Share Posted May 15, 2017 I recently bought a polished top rad pipe to replace my stock one and just wondering if I can change it over without draining coolant and won't get any air in system or will it make a mess Quote Link to comment Share on other sites More sharing options...
mplavery Posted May 15, 2017 Share Posted May 15, 2017 (edited) Just get a bit of pipe (breather pipe), cleaned out plastic 6 pint bottle, take the rad cap off and place the pipe inside the rad (will only go in about 5cm) and into the bottle on the floor and syphon it out mate, just enough to remove the top pipe on a TT anyways Just taken mine off to get re gold plated Edited May 15, 2017 by mplavery (see edit history) Quote Link to comment Share on other sites More sharing options...

markssupra Posted May 16, 2017 Share Posted May 16, 2017 You wont get any from just draining enough to remove the top hose, although you could run the engine with the rad cap removed, once it starts to warm up, put the rad cap back on. Check your expansion tank after a few runs to make sure the coolant level is ok, the level will settle. Quote Link to comment Share on other sites More sharing options...

SupraLEDrears Posted May 16, 2017 Share Posted May 16, 2017 Don't worry about air, it's a self bleeding system Quote Link to comment Share on other sites More sharing options...
