AC switch

ss2115 · Apr 30th, 2018, 09:30

I am replacing the low pressure switch on the AC system of our 850.
Its the one on the evaporator pipe coming out of the firewall.

Apparently under the high pressure switch behind the headlight is a schroder valve (like a tyre valve), so it can be swapped out with little loss of gas.

Does anyone know if the low pressure switch is also over a schroder valve please???

I cannot guarantee that the 850 is the same but my V70 has a schrader valve under the low pressure switch.

The switch can be changed without evacuating the gas from the system, as you say.
