noxu Posted April 1, 2022 Share Posted April 1, 2022 Sorry to bring up an old topic but due to corroded pipes I am going to get the rear air pipes welded up but after reading old topics am not sure if they should be welded up as two seperate pipes or made into a loop, I cannot find a schematic in my manual and talking to other owners there is an arguement that they should be looped to allow coolant to circulate. Can anybody confirm the correct way to isolate the rear air con Quote Link to comment Share on other sites More sharing options...
Lexus Owners Club Posted April 4, 2022 Share Posted April 4, 2022 Looping the pipes would be best to allow the coolant to circulate and bypass the A/C unit Quote Link to comment Share on other sites More sharing options...
