I have a 1989 740GL with an aftermarket radiator. The radiator has the plug style temp sensor/fan switch. Up here in Minnesota, we never had an issue with the thing leaking. However, on a recent long distance drive through some higher terrain and doing several mountain climbs, the plug either worked itself loose or gave in to higher pressure and we lost some fluid (thought we blew a head gasket for a second...) I pushed the plug back in and rigged it with some high-temp tape. Back in the flat lands, we never had an issue with it. Could the mountain climbs caused higher pressure and the plug to unseat? If so, is there a fix for this. I was wondering about some gasket sealer or RTV, but am worried about how this would hold up and how it would adhere to the plastic radiator.
