adsdsasdasdasda Posted July 5, 2021 Share Posted July 5, 2021 Hey, guys recently I have noticed that my car had been leaking coolant. Luckily I caught it early and there is no damage but I want to get this fixed asap! I have a 1981 280zx and I can't figure out what this part/pipe is. Any help would be helpful full, the image below: P.S. If you find any diagrams that have this part please post them, I couldn't find any <3 Quote Link to comment Share on other sites More sharing options...
NewZed Posted July 5, 2021 Share Posted July 5, 2021 (edited) It might be the pipe to the air regulator heating block. The air regulator sits on an aluminum plate with coolant running through it. The plate gets hot and keeps the regulator closed. Probably hard to get to but all you need to do is replace the hoses. Here's a picture of the regulator. It has two large air hoses that connect on each side. The plate is underneath. Edited July 5, 2021 by NewZed Quote Link to comment Share on other sites More sharing options...

NewZed Posted July 5, 2021 Share Posted July 5, 2021 It's from the Factory Service Manual, Engine Fuel chapter. You can download it from the ClassicZcars.com site. https://www.classiczcars.com/files/category/14-280zx/ Quote Link to comment Share on other sites More sharing options...
