My wife's Series V also ran hot for the first two years we owned it.
Attempts to relieve this included: different fan and a triple cored
radiator. Finally during a rebuild on the upper half of the engine we
discovered the heads cooling portals were almost completely clogged with
corrosion. Certainly a cleaned out rewelded head would alleviate this
problem.....but nooooo!!!
At this point we decided to test the heat of the radiator coolant
independantly of the gauge. Sure enough, the gauge was reading higher
temperatures than the coolant actually was. A look up under the dash
revealed a loose wire on the temp. gauge. Swiftly repaired and the car has
rarely read higher than halfway (85?) on the gauge since then.
Of course, I don't think that this was the cure for the overheating engine
but after all the other steps were taken it was nice to have the deceptive
gauge brought into line.
