Maverik Posted April 12, 2016 Share Posted April 12, 2016 Hi folks, I've just removed the interior AC assembly from a defender and this clear syrup type substance ran out the main AC refrigerant pipe... which I wasn't exactly anticipating... anyone able to shed any light on it for me? It has a bitter what I think of as a silicone smell...? Quote Link to comment Share on other sites More sharing options...
pat_pending Posted April 12, 2016 Share Posted April 12, 2016 It's the lubricating oil for the compressor. It gets pumped round the system with the gas, it may also have some leak detection dye in it. It's normal on all A/C systems. Quote Link to comment Share on other sites More sharing options...
Maverik Posted April 12, 2016 Author Share Posted April 12, 2016 Ah righty ho, I guess I need to top it up then when I stick it all back together? - any links for the stuff I'm looking for? Quote Link to comment Share on other sites More sharing options...
pat_pending Posted April 12, 2016 Share Posted April 12, 2016 It's call PAG oil, there are various viscosities available, spec should be in the manual but any A/C specialist will have the info'. No need for you to put any in as the oil is replenished when the system is re gassed, there are measured quantities for each component that's been drained/replaced. If you tell whoever re gasses the system what you've done, they'll be able to ensure the correct oil spec' and quantity are injected with the gas.
