Used original Smiths electric water & oil temp gauges & sending units from my racing MG. Manifold location for water temp & oil pan location for oil temp. 50/50 water glycol with 2 cans of H2O Wetter. Ambient temps now 65 deg F in TX, water temp hits 210 deg F & oil temps hits 215-200 deg. Laser shot of radiator show about 180 deg F. All air burped out of system, 10 quarts of oil in engine, oil cooler and filter. This is way too hot for my liking especially when summer temps here will hit 95 to 100 deg F. Could both sending units be bad? Any opinions are appreciated. |
Why are you concerned about 210°F? That's well within normal range and far from overheating or boiling over - unless you're running straight water with no pressure cap.
As others have pointed out, the 160°F thermostat is too low, and a 180° or 190° would be much better. As you have noted, it made no difference on your temperatures.
