    Default Any idea what these could be?

    Have been wondering what these in the engine bay of my Prado 120 could be:

    One is located in front of the radiator fan and has a grey plastic cap with 'H' on it.

    The other is located close to the dipstick and has a grey plastic cap with 'L' on it.

    Metal pipes are connected to them that appear to snake all over the show. Could it have something to do with a pressurized air system?

    If someone has a good idea what they are, I'd be very interested to know.

    Thank you for the replies, guys! There goes my hopes for some super-duper built-in air compressor system, guess I'll just have to stick to the little 72l compressor

    Just be sure to keep those caps on. It keeps dirt out the valves, and prevents someone from accidentally pushing the valve open. Aircon refrigerant is nasty stuff, you donít want it on your skin.
