Speaking of replacement radiator caps - Does anyone know anything (good or bad) about the 'THERMOCAP' Radiator Caps with the built-in calibrated thermometer that JEGS sells in their catalog? If it is good, what pressure selection would be optimum for the 5.7?

Thanks,

should be around 15 psi i would think, look at the cap on the truck should say.
