Airflow speed through a radiator is a major influence on the heat it loses. Vehicle speed affects this, in rough proportion to the engine effort, thus giving crude self-regulatory feedback. Where an additional volvo cooling fan is driven by the engine, this also tracks engine speed similarly.. Engine-driven fans are often regulated by a viscous-drive clutch Use a section of heater hose or clear vinyl tubing that fits the nipple and put funnel into the hose.
