Re: Engine gets hot at idle

How many blades does your fan have? How many rows does your radiator have?

My fan has 7 and my radiator has 3 rows. My vacuum advance is on manifold vacuum and initial idle timing is set for around 10-12 BTC. No overheat at idle even when running AC on a hot day.

Getting a sending unit to match OEM temp gauges can be an exercise in frustration since different years require different sending units and a PO may have swapped either or both. The typical chain parts store sending unit generally won't work with the OEM gauge. Probably why you have the under dash units.
