Reply to "Oil Temp and Coolant Temp"

Hi John

I don't usually visit this forum; however, another member informed me of your post. As Larry points out, my oil temp sender is in the oil pan and the water temp sender is in the water pump. I haven't seen the final article; so, I do not know if the water temp sender info was edited out. In the article, I mention relocating it further from the bypass and raising the sender temp to 190 to allow more heat in the coolant. The car was running too cool. In the water pump, the water temp sensor sees the temp of coolant just prior to entering the block. I would have preferred a location just aft of the radiator or even in the radiator's return tank. However, the oriface was already present on the water pump and not in those other locations and I saw no disadvantage using it. I suppose one could argue the water pump is an ideal location as it is closest to the actual temp that the coolant quenches the block. Honestly, I would go through no extra effort to reproduce that location.
