300TE Temp Sensor Question
Hello to all,
I've got a 1991 300TE 4matic. I've verified the aux fan resistor is open and the coolant temp sensor on the receiver/dryer is not functioning. Both will be replaced shortly.
Here's my question:
Can someone confirm that the coolant temp sensor on the recvr/dryer does not breach the pressure boundary of the a/c system? I would imagine it does not, but I'd hate to blow R12 in my face when I try to replace the sensor if the sensor is part of the boundary.
Your help is appreciated!!
