Servo Hot Water Valve Assembly

The Servo Hot Water Valve Assembly (part number 461170) is a precision climate control component designed for custom vehicle heating systems, particularly in classic car restorations and modern hot rod builds. This assembly manages hot water circulation to cabin heaters with servo-controlled accuracy, allowing drivers to maintain consistent cabin temperatures without manual adjustment.

This valve assembly provides smooth, gradual adjustments that maintain stable cabin warmth across varying engine load conditions. The compact 5.15 x 2.8 x 6.2 inch form factor (weighing just 0.43 lbs) allows flexible mounting in engine bays or under-dash installations, while its construction ensures durability in high-heat environments typical of engine compartments.

This servo valve assembly is ideal for builders and mechanics installing custom climate control systems in street rods, muscle cars, and classic vehicles where OEM heating solutions are inadequate or unavailable. Installation requires integration into the vehicle's heating system for optimal performance.
