Greetings,
I've finally got to the point where I have my GTS on the road and now working out the bugs.
One of the more persistent issues is temperature with the 340. I thought I had it licked but It's still acting funny. When I go for a ride the Stewart Warner temp gauge says 185 and the factory temp gauge points straight up and reads 1/3 of the sweet spot, the gauges read normal but the engine seems hot and I hear the coolant burping around. I have no over flow bottle so the tube goes from the neck to under the car. Today I was leaving a trail of coolant drops as I was coming up the driveway.
I can't barley touch the rad even after it's sat for a while.
Top radiator hose has pressure lower isn't collapsed (at least when I look at it)
When its cold it starts right up. after a drive and the temp heats up it doesn't want to start.
