As engine warms up, the temp needle rises to spang in the middle of the scale. After a few minutes of driving, it rises to very near to the top (somewhat, but not entirely, in the red), sits there for a minute or so, then marches back down to sit in the middle. Repeats every 4-5 minutes.
New thermostat. Replaced the mechanical voltage stabilizer with an electronic one (reads right at 10.0 volts). Gas gauge was steady all along, no change. Unwrapped the wiring about a foot to check for bad insulation, nothing untoward found.
It MAY be that the engine is actually heating up and cooling down, but there is no indication of a problem in performance, and the cycle seems pretty fast for actual changes in engine temp. Hard to tell, I have never been in a situation to be able to check with an IR thermometer when it reads hot.
And yes, the path from the intake manifold tower to the radiator inlet is clear.
Any ideas? Might be a fault in the temp sensor. Since I am in the US, getting one is pricey due to shipping. Does this sensor cross with anything more common (e.g., MG/Triumph etc)?
