---------------------------- After having 2 coolant leaks, rear heater and a oil cooler hose, I decided to monitor my coolant systems pressure. I installed a couple of extra senders for the electric oil pressure gauge and a switch so I can now monitor my oil, fuel or coolant pressure. The coolant pressure is 0 when cold and slowly rises along with the coolant temperature to around 10 psi, I assumed it would sit around 10 psi while the engine is hot. Yesterday was the first time I have taken a long trip, about 3hrs since installing the sender. After climbing to 10 psi it started dropping off gradually after 30 minutes of driving to 2-4 psi and stayed there the rest of the trip, it did the same thing on the way home. I appeal to the wisdom of the list, do I have a problem? I can find no coolant leaks, drips or drops. Temperature here has been in the 20- 40 degree F range. Any ideas sought and appreciated.
