Temperature Sender

[njsteve]

Well, I bought one of the Lectric Limited senders, installed it in the cyl head in the factory spot and it reads 25 degrees higher than the radiator water temperature measured with an accurate thermometer dipped into the coolant.

So much for the accurately calibrated reproductions. [img]<<GRAEMLIN_URL>>/thumbsdown.gif[/img]

The explanation provided above, that the cylinder head will give a higher temp reading than the block location may be true, but that doesn't explain the accuracy of the original factory senders. Were they undercalibrated to compensate for higher cyl head temps?
