Ahmedsinc 414 Report post Posted July 14, 2015 Needing a good used M10 thermostat please. Picked up an '85 318i as a daily while Pigpen is off the road, temp needle never moved out of the blue zone when bringing it home last week. Highway driving and less than 6* outside when brought home, ran in the driveway for approx 30 min today and still on the cool side. Failing that, is it possible to unstick a stuck thermostat? Will go for new if no other choice but figured someone might have a good old one laying about after a cooling system service. Chur! Quote Share this post Link to post Share on other sites
