Climate Control Servo for 78 450sl
 

My current climate control servo is leaking coolant...any gotchas associated with changing this part out myself?

if it's leaking in the main body it's likely "toast" since fluid has got into the motor. Yopu might try getting a rebuilt aluminum body one from George Murphy at Performance Analysis. He advertises in The Star and also Hemmings. good luck. he is rebuilding a second one for me now!
