The parts stores temp senders have the WRONG RESISTANCE values.

You need to add resistors in paralel to get them to read right. Use you infared thermometer gun and add/substract resistance. Get a resistor pack from Radio Shack with combination of resistors around 10 ohms.




If this is the case (why not it's only Mopar?), then has anybody ever thought to post the proper resistance range for the OEM sender so we can compare? I can imagine this would be hard to do for somebody who has one....

Also, is it safe to say that if the aluminum WP housing is pegging around 165* with the IR thermometer, then the coolant inside would be within a few degress? Or could there be a huge difference?
